Description

  The present invention relates to a control device, a control method, and a program.

  A so-called actual quantity system is currently employed as a system for determining the capacity and the electricity charge of power supplied to businesses represented by buildings and factories. The actual quantity system is a system that determines contract power based on the maximum power demand in the past year. However, the maximum demand power means the maximum value of power consumption for 30 minutes.

  For this reason, if the amount of power consumption for a certain 30 minutes increases, even if the amount of power consumption is small at other times, the electricity bill for the next year may be relatively high. Therefore, it is important to suppress the peak of power consumption and suppress the power consumption for 30 minutes as much as possible. It is also desirable to suppress the peak of power consumption from the viewpoint of power supply and demand efficiency.

  Accordingly, various techniques for suppressing the peak of power consumption have been proposed (see, for example, Patent Document 1). Patent Document 1 describes an apparatus that prevents a demand of a consumer from exceeding a target value by creating an operation schedule of a large number of air conditioners that temporally disperse areas where air conditioning does not work. Yes.

JP 2013-135582 A

  Conventionally, the actual amount system has been adopted only when electric power is supplied to an operator. However, in the future, the actual amount system may be adopted even when power is supplied to the house. Here, since many air conditioners as assumed in Patent Document 1 are rarely installed in a house, when the device described in Patent Document 1 is applied to a house, devices other than the air conditioner are used. The time for stopping various devices including the above is dispersed in terms of time. In such a case, it is considered difficult to suppress power consumption without impairing the comfort of the user in the house.

  The present invention has been made under the above circumstances, and an object thereof is to suppress power consumption without impairing the comfort of a user in a house.

  In order to achieve the above object, the control device of the present invention includes an acquisition unit that acquires a measured value of total power supplied from a commercial power source to a plurality of electrical devices installed in a house, and a measured value in a predetermined period. If the integrated value up to the current time exceeds the threshold, the controlled device that operates by consuming power for a time longer than a predetermined length among a plurality of electrical devices is controlled, and the power consumption of the controlled device Control means for limiting the integrated value in the period of the total power to a target value or less by suppressing.

  ADVANTAGE OF THE INVENTION According to this invention, power consumption can be suppressed without impairing the comfort of the user in a house.

  FIG. 2 shows a hardware configuration of the control device 10. As shown in FIG. 2, the control device 10 is configured as a computer having a processor 11, a main storage unit 12, an auxiliary storage unit 13, an input unit 14, an output unit 15, and a communication unit 16. The main storage unit 12, auxiliary storage unit 13, input unit 14, output unit 15, and communication unit 16 are all connected to the processor 11 via the internal bus 17.

  The processor 11 includes a CPU (Central Processing Unit). The processor 11 exhibits the functions described later by executing the program P1 stored in the auxiliary storage unit 13.

  The main storage unit 12 includes a RAM (Random Access Memory). The main storage unit 12 loads the program P1 from the auxiliary storage unit 13. The main storage unit 12 is used as a work area for the processor 11.

  The auxiliary storage unit 13 includes a nonvolatile memory represented by an HDD (Hard Disk Drive) or a flash memory. The auxiliary storage unit 13 stores various data used for the processing of the processor 11 in addition to the program P1. The auxiliary storage unit 13 supplies data used by the processor 11 to the processor 11 in accordance with an instruction from the processor 11 and stores the data supplied from the processor 11.

  The input unit 14 includes an input key and a capacitive pointing device. The input unit 14 acquires information input by the user and notifies the processor 11 of the information.

  The output unit 15 includes a display device represented by an LCD (Liquid Crystal Display) and a speaker. The output unit 15 according to the present embodiment forms, for example, a touch screen by being formed integrally with a pointing device that constitutes the input unit 14. Then, the output unit 15 displays various graphics and characters to the user according to instructions from the processor 11 and reproduces an acoustic signal.

  The communication unit 16 includes a communication interface circuit for communicating with the measurement device 20, the electrical device 30, the terminal 40, and the server 60 connected to the control device 10 via a communication line. The communication unit 16 notifies the processor 11 of information included in a signal received from the outside, and transmits a signal indicating the information output from the processor 11 to an external device.

  FIG. 3 shows a functional configuration of the control device 10. The functions of the control device 10 shown in FIG. 3 are realized by the above hardware operating in cooperation. In FIG. 3, the electric device 30 is shown as a general term for the electric devices 31 to 39. The control device 10 has, as its function, an acquisition unit 110 that acquires information used for control by the control device 10, a control unit 120 that controls each component of the control device 10, and information used by the control device 10. A storage unit 130 that stores information and a UI (User Interface) unit 140 that receives information from the user and presents the information to the user are included.

  The acquisition unit 110 is realized mainly by the cooperation of the processor 11 and the communication unit 16 illustrated in FIG. The acquisition unit 110 acquires device information regarding the electrical device 30 from the measurement device 20, the electrical device 30, the terminal 40, and the server 60. The device information includes the measured value of the total electric power of the electric device 30 measured by the measuring device 20, the current set value and the operation mode of the electric device 30, and the set value and the operation mode newly designated by the user. It is. Further, the acquisition unit 110 requests the server 60 to transmit information used by the control unit 120 in accordance with an instruction from the control unit 120, and acquires information from the server 60 in response to the request. Then, the acquisition unit 110 outputs the acquired information to the control unit 120, and the control unit 120 stores this information in the storage unit 130. However, the acquisition unit 110 may store information directly in the storage unit 130 without using the control unit 120.

  The control unit 120 is realized mainly by the processor 11, the main storage unit 12, and the communication unit 16 shown in FIG. The control unit 120 refers to device information held in the storage unit 130 and the server 60 to control the controlled device. This controlled device is a long-term operating device that consumes electric power and operates over a longer time than a predetermined time in the electric device 30. The controlled device is, for example, an electrical device in which the average length of one time of operation in the past in the house 200 is longer than a predetermined length to be described later, and the past usage history of the electrical device 30 is used. Based on this, the control unit 120 selects the electric device 30.

  As shown in FIG. 3, the control unit 120 includes, as its function, a device suppression module 121 that suppresses power consumption of the electrical device 30, a suppression release module 122 that cancels suppression of power consumption for the electrical device 30, It has the prediction module 123 which estimates the power consumption of the apparatus 30, and the threshold value update module 124 which updates the threshold value for controlling the electric apparatus 30.

  The device suppression module 121 controls the controlled device of the electrical device 30 when the integrated value up to the current time of the total power of the electrical device 30 in the specified period exceeds the threshold, and the power consumption of the controlled device By limiting the value, the integrated value of the total power during the specified period is limited to a target value or less. The threshold value is an upper limit value of the power consumption that is assumed that the total power consumption of the electrical device 30 during the specified period does not exceed the target value when the currently operating electrical device 30 continues to operate. The derivation of the threshold will be described later. In the following description, the integrated value of electric power and the amount of electric power are used in combination with no particular distinction.

  The suppression release module 122 releases the suppression of power consumption for the controlled device within a range where the total power consumption of the electrical device 30 during the specified period is assumed not to exceed the target value.

  The prediction module 123 predicts the transition of the power consumption of the controlled device within the specified period and the power consumption of the short-term operating device during the specified period based on the device information. The short-term operating device is a device other than the controlled device that is the long-term operating device among the electric devices 30 and is a device that does not fall under the control target of the control device 10.

  The threshold update module 124 updates the threshold used by the device suppression module 121 and the suppression release module 122 based on the device information.

  The storage unit 130 is realized mainly by the auxiliary storage unit 13 shown in FIG. The device information stored in the storage unit 130 is temporarily stored by the control unit 120, and old information that has passed a certain period since being stored in the storage unit 130 is stored in the server 60 by the control unit 120. The This certain period is, for example, one day or one week. The device information stored in the storage unit 130 includes operating device information 131 related to the currently operating electrical device 30, suppression device information 132 related to the controlled device whose power consumption is currently suppressed by the device suppression module 121, and Is included.

  FIG. 4 shows an example of the operating device information 131. Of the operating device information 131, “operating device” is a number for identifying the device, and in FIG. 4, a number equal to the reference numerals of the electrical devices 31 to 39 is used. The “instantaneous power consumption” is an instantaneous value of the power consumption of the device in operation, and is updated using a value periodically output from the acquisition unit 110. The “apparatus setting value” is a parameter set for an operating apparatus, and is updated using a value periodically output from the acquisition unit 110.

  The “operation type” indicates whether the average operation time of the device is longer than a predetermined length, and is information for identifying the long-term operation device and the short-term operation device. A long-term operating device whose “operation type” is long corresponds to a controlled device to be controlled by the control unit 120, and a short-term operating device whose “operation type” is short-term does not correspond to a controlled device. Since “operation type” is information that is frequently used by the control unit 120, it is acquired by the acquisition unit 110 from the server 60 and stored in the storage unit 130.

  The “suppression priority” is a priority for determining a controlled device that suppresses power consumption among a plurality of controlled devices. A controlled device having a large “suppression priority” is controlled by the device suppression module 121 in preference to a controlled device having a small “suppression priority”. The “suppression priority” is calculated by the device suppression module 121. The “operation start time” is the time when the device starts operating, and is the time when information indicating that the device has started operating is first acquired by the acquisition unit 110.

  FIG. 5 shows an example of the suppression device information 132. Among the suppression device information 132, “device being suppressed” is a number for identifying the device, and in FIG. 5, a number equal to the reference numerals of the electrical devices 31 to 39 is used. The “operation frequency” is the total operation time per day of the device, and is acquired from the server 60 by the acquisition unit 110 and stored in the storage unit 130. “Effect on comfort” is an index related to the comfort of the user of the energy management system 100, and indicates whether the start / stop of the device is related to the comfort of the resident of the house 200. This “influence on comfort” is acquired from the server 60 by the acquisition unit 110 and stored in the storage unit 130.

  Further, the “release priority” is a priority for determining a controlled device that releases the suppression of power consumption among the controlled devices whose power consumption is suppressed. The controlled device having a large “release priority” is controlled by the suppression release module 122 in preference to the controlled device having a small “release priority”. The “release priority” is calculated by the suppression release module 122.

  The “pre-suppression set value” is a parameter set for the device immediately before power consumption is suppressed by the device suppression module 121, and is included in the operating device information 131 when power consumption is suppressed. It is equal to “device setting value”. The “predicted power consumption” is a predicted value of the power consumption in a specified period when the suppression of power consumption is released. However, the “predicted power consumption” is the power consumption after the current time and is predicted by the prediction module 123.

  Returning to FIG. 3, the UI unit 140 is realized mainly by the processor 11 and the communication unit 16 illustrated in FIG. 2. The UI unit 140 determines data to be displayed on the screen of the terminal 40 and transmits this data to the terminal 40.

  For example, the UI unit 140 causes the terminal 40 to display a setting value instructed by the user. The text 141 in FIG. 6 indicates that the user has permitted the peak cut control as a mode for dealing with the actual amount system.

  Further, the UI unit 140 displays a screen indicating the control result so that the user can check the result of these controls when the power consumption is suppressed or canceled by referring to the suppression device information 132. Let FIG. 7 shows an example of a screen showing the result of suppressing power consumption. Note that the UI unit 140 may notify the user of the current suppression state by displaying a pop-up indicating the suppression content on the television receiver or the terminal 40 when the power consumption is suppressed.

  Also, the UI unit 140 refers to the suppression device information 132 and displays a screen showing these devices so that the user can check the devices whose power consumption is currently suppressed. In FIG. 8, controlled devices whose power consumption is suppressed are shown with double circle marks 142. In FIG. 8, a mark 142 in the rooms R2, R6, and R7 indicates that the power consumption of the floor heating facility is suppressed, and a mark 142 in the room R3 indicates that the power consumption of the air conditioner is suppressed. Indicates.

  The energy management system 100 may be configured without the terminal 40, and the UI unit 140 may be realized by the input unit 14 and the output unit 15 illustrated in FIG.

  Returning to FIG. 1, the measurement device 20 uses the sensor attached to the power line for supplying power from the commercial power supply 70 to the electrical devices 31 to 39, and is consumed by being supplied from the commercial power supply 70 to the house 200. Measure. The sensor according to the present embodiment is a current transformer and is attached to a power line of a distribution board of the house 200. This sensor outputs a signal indicating the value of the current flowing through the power line to the measuring device 20. Since the voltage applied to the house 200 from the commercial power supply 70 is defined in advance, the measuring device 20 can obtain the power supplied from the commercial power supply 70 to the house 200 from the output of the sensor. Then, the measuring device 20 repeatedly transmits information indicating the measured power value to the control device 10.

  However, the measuring device 20 may measure the power or the integrated value of the power amount as indicating power. Since the differential value of the integrated value of the electric power or the electric energy is equal to the electric power and mutual conversion is easy, the integrated value and the electric power can be treated as equivalent.

  The commercial power source 70 is a power network or a system power source operated by an electric power company. The commercial power source 70 supplies electric power to the house 200 with a predetermined voltage such as AC 100V or 200V.

  The electric devices 31 to 39 are home appliances and facilities that are managed by the energy management system 100. The electric devices 31 to 39 include, for example, an air conditioner, a lighting device, an IH (Induction Heating) cooking device, a refrigerator, a floor heating facility, and a hot water storage type water heater.

  The terminal 40 is, for example, a personal computer installed in the house 200, a wall-mounted remote controller, or a tablet terminal or a smart phone carried by a user who is a resident of the house 200. The terminal includes an input unit for receiving input from the user and an output unit for presenting information to the user. The input unit is, for example, a switch, a button, an input key, or a microphone. The output unit is, for example, a display screen or a speaker represented by an LCD (Liquid Crystal Display). The terminal 40 may have a touch screen in which an input unit and an output unit are integrally formed.

  The terminal 40 receives information input from the user to the input unit and transmits this information to the control device 10 or notifies the user of information generated by the control device 10. The information input by the user includes, for example, a setting value for operating the electrical devices 31 to 39. The information generated by the control device 10 includes, for example, information for configuring and updating the display screen, and acoustic data reproduced by a speaker.

  The network 50 is a communication network outside the house 200 and is a wide area network represented by the Internet, for example.

  The server 60 is a device that collectively manages information used by each of the control devices 10 installed in a plurality of houses. The server 60 stores device information received from the control device 10. Further, the server 60 acquires and stores the demand data represented by the maximum demand power of each house, the month when the maximum demand power is updated, and the contract power table obtained from the electric power company via the network 50. .

  The server 60 acquires the total power consumption of the electrical device 30 in the specified period from the measuring device 20 through the control device 10 at the end time of the specified period. When the acquired total power consumption is larger than the currently stored maximum demand power, the server 60 updates the maximum demand power to the acquired total power consumption, and updates the maximum demand power update month. Update to the current month. Further, the server 60 calculates the monthly maximum power demand for each of January to December. The monthly maximum power demand means the maximum power demand for one month and is updated annually for each month. If the current month becomes the renewal month without the maximum demand power value being updated for one year, the maximum demand power is calculated using the maximum monthly demand power for the past 11 months and the current month. Update, and update the update month to the month to which the maximum value belongs.

  FIG. 9 shows an example of the device information database 61 stored in the server 60. In the device information database 61, “Electrical device” is a number for identifying the electrical devices 31 to 39, and in FIG. 9, a number equal to the code of the electrical devices 31 to 39 is used.

  The “average power consumption” is an average value of power consumption when the electric device 30 is operating. This “average power consumption” may be calculated from the operation history of the electrical device 30 or may be obtained from the specifications of the electrical device 30. The “average operation time” is an average value of one operation time from the start of operation of the electrical device 30 to the end of operation. This “average operating time” is obtained from the history of operating states notified from the electrical device 30 to the control device 10.

  The “operating type” is classified according to whether the “average operating time” of the electrical device 30 is longer than a predetermined time, and the “operating type” of the electrical device 30 having a long “average operating time” is long-term. The “operating type” of the electrical device 30 having a short “average operating time” is a short term. The predetermined time is, for example, 30 minutes.

  The “final operation start time” indicates the time when the electrical device 30 last started operation. The “operation frequency” indicates an average value of the time during which the electrical device 30 is operating within one day. In addition, “existence” is assigned to “influence on comfort” when the model of the electrical device 30 is, for example, an air conditioner or a floor heating facility, and “none” is assigned otherwise.

  Further, the “rising pattern” is obtained by classifying the transition of power consumption after activation of each electrical device 30 into the three patterns shown in FIG. The “rise time” indicates the time from when the electric device 30 is activated until the power consumption converges to a steady state.

  FIG. 10 shows an example of transition corresponding to A, B, and C of the “rising pattern”. The A pattern is a pattern in which power consumption increases immediately after the start of operation due to the influence of an inrush current. For example, a vacuum cleaner corresponds to the A pattern. The B pattern is a pattern in which the inrush time is short and the influence of the inrush current is small, and the power consumption is constant immediately after the start of operation. For example, the lighting device corresponds to the B pattern. The C pattern is a pattern in which power consumption is gradually reported immediately after the start of operation without being affected by the inrush current by the soft start function. For example, an air conditioner corresponds to the C pattern.

  Next, control processing executed by the energy management system having the above configuration will be described with reference to FIGS. The control process shown in FIG. 11 is executed every minute, for example.

  First, the control unit 120 determines whether or not execution of suppression control is permitted by the user (step S1). Specifically, the control unit 120 determines whether or not the user has input to the terminal 40 that permission to execute peak cut control for accommodating the actual amount system.

  When it determines with execution of suppression control not being permitted (step S1; No), the control part 120 complete | finishes a control process. On the other hand, when it determines with execution of suppression control being permitted (step S1; Yes), the control part 120 is the integrated value of the total electric power until the present time of the electric equipment 30 in regulation time is more than a threshold value. It is determined whether or not (step S2).

  When it determines with the integrated value of total power being more than a threshold value (step S2; Yes), the control part 120 performs an apparatus suppression process (step S3). This device suppression process is a process in which the device suppression module 121 suppresses the power consumption of the controlled device. Details of the device suppression process will be described later.

  On the other hand, when it determines with the integrated value of total power not being more than a threshold value (step S2; No), the control part 120 performs suppression cancellation | release process (step S4). This suppression cancellation process is a process in which the suppression cancellation module 122 cancels the suppression of power consumption. Details of the suppression release processing will be described later.

  Following the device suppression process (step S3) or the suppression release process (step S4), the control unit 120 executes a prediction process (step S5). This prediction process is a process in which the prediction module 123 predicts the power consumption in the specified period of the controlled device and the short-term operation device. Details of the prediction process will be described later.

  Next, the control part 120 performs a threshold value update process (step S6). This threshold update process is a process in which the threshold update module 124 updates the threshold. Details of the threshold update process will be described later. Thereafter, the control unit 120 ends the control process.

  Next, details of the device suppression process (step S3) shown in FIG. 11 will be described with reference to FIG.

  In the device suppression process, the device suppression module 121 refers to the “operation type” of the operating device information 131 and determines whether the controlled device to be controlled is currently operating (step S31).

  If it is determined that the controlled device is not currently operating (step S31; No), the device suppression module 121 ends the device suppression process. On the other hand, if it is determined that the controlled device is currently operating (step S31; Yes), the device suppression module 121 calculates the ratio of the remaining operating time for each controlled device that is operating, and gives priority to suppression. The degree is calculated (step S32).

  Specifically, the device suppression module 121 acquires the average operation time stored in the server 60 and the operation start time of the operation device information 131. Then, the device suppression module 121 predicts the operation end time by adding the average operation time to the operation start time. The device suppression module 121 calculates the ratio of the remaining operation time from the current time to the predicted operation end time to the average operation time. And the apparatus suppression module 121 makes a suppression priority low, so that this ratio is large. Thereby, the power consumption of the controlled device having a low remaining operating time ratio is preferentially suppressed.

  FIG. 13 shows an example of calculating the suppression priority. In the example shown in FIG. 13, a natural number starting from 1 is assigned to each device as the suppression priority in descending order of proportion.

  Returning to FIG. 12, after step S <b> 32, the device suppression module 121 suppresses power consumption of the device having the highest suppression priority (step S <b> 33). Specifically, the device suppression module 121 stops or interrupts the operation of the controlled device having the maximum suppression priority, or changes the operation mode of the controlled device to suppress the output. For example, the device suppression module 121 changes the cooling operation of the air conditioning device to the air blowing operation, or changes the set temperature of the cooling operation to a high value. Thereby, the total power consumption of the electric equipment 30 will fall.

  Next, the device suppression module 121 deletes the controlled device targeted for suppression from the operating device information 131 and adds it to the suppression device information 132 (step S34). After the device suppression module 121 transmits a control command to the controlled device in step S33, it may take time until the power consumption of the controlled device actually decreases. In such a case, there is a possibility that the control command is repeatedly transmitted to the same controlled device in step S33 that is repeatedly executed. By executing the procedure of step S34, such repeated transmission can be prevented.

  Next, as a result of suppressing the power consumption of the device, the device suppression module 121 determines whether or not the value predicted for the integrated value of the total power of the electrical device 30 in the specified period is equal to or less than the target value (step S35). . Specifically, the device suppression module 121 executes a process equivalent to a prediction process (step S5) described later, and determines whether or not the integrated value of the total power at the end time of the specified period is equal to or less than the target value. To do.

  If it is determined that the predicted value is not less than or equal to the target value (step S35; No), the device suppression module 121 updates the predicted value of total power (step S36). Specifically, the device suppression module 121 updates the predicted power consumption of the controlled device in a specified period after the current time to a value obtained by subtracting the suppressed power consumption of the controlled device. Thereafter, the device suppression module 121 repeats the processing after step S33. Thereby, suppression of the power consumption with respect to a to-be-controlled apparatus is repeated until it is estimated that the integrated value of the total electric power in a regulation period will become below a target value.

  On the other hand, when it is determined that the predicted value is equal to or less than the target value (step S35; Yes), the process executed by the control unit 120 returns from the device suppression process to the control process shown in FIG.

  Next, details of the suppression release process (step S4) shown in FIG. 11 will be described with reference to FIG.

  In the suppression cancellation process, the suppression cancellation module 122 first refers to the suppression device information 132 and determines whether there is a controlled device whose power consumption is being suppressed (step S41).

  When it determines with there being no apparatus currently suppressed (step S41; No), the suppression cancellation | release module 122 complete | finishes a suppression cancellation | release process. On the other hand, when it is determined that there is a device being suppressed (step S41; Yes), the suppression cancellation module 122 acquires “operation frequency” and “influence on comfort” of the suppression device information 132, and the cancellation priority. Is calculated. Specifically, the suppression cancellation module 122 sets “operating frequency” as a reference value, and when “impact on comfort” is present, sets a value that is twice the reference value as a cancellation priority, When the “effect” is “none”, a value obtained by multiplying the reference value by an equal magnification is set as the release priority.

  Next, the suppression cancellation module 122 selects a combination having the highest cancellation priority from all combinations of controlled devices being suppressed (step S43). For example, the suppression release module 122 selects a combination of the electric devices 36, 37, 38, and 39 in the example shown in FIG.

  Next, the suppression release module 122 determines whether or not a value obtained by adding the power consumption when the selected controlled device is activated to the predicted power consumption of the controlled device in a specified period after the current time is equal to or greater than a threshold value. (Step S44).

  If the determination in step S44 is affirmative (step S44; Yes), the suppression release module 122 excludes the selected combination from the combinations of controlled devices (step S45). Thereafter, the suppression release module 122 repeats the processing after step S43. For example, in step S43 executed for the second time in the example shown in FIG. 13, a combination of the electric devices 36, 37, and 38 is selected.

  On the other hand, when the determination in step S44 is negative (step S44; No), the suppression release module 122 acquires the setting value before suppression from the suppression device information 132, and the combination selected in step S43 executed last. The suppression of power consumption for the device is released (step S46). Thereby, the state of the controlled device in which the power consumption is suppressed is restored to the state before the power consumption is suppressed. At this time, the suppression cancellation module 122 deletes the device whose suppression is canceled from the suppression device information 132 and adds it to the operating device information 131.

  Thereafter, the process executed by the control unit 120 returns from the suppression release process to the control process shown in FIG.

  Next, details of the prediction process (step S5) shown in FIG. 11 will be described with reference to FIG.

  In the prediction process, the prediction module 123 first predicts the standby power amount during the specified period of the electrical device 30 that is not operating (step S51). Specifically, the prediction module 123 uses the minimum value of power consumption in the past 24 hours held in the storage unit 130 as standby power, and calculates a predicted value Ew of standby power consumption in a specified period after the current time ( Step S51).

  Next, the prediction module 123 refers to the “operation type” of the operating device information 131 and acquires the number N of controlled devices in operation (step S52).

  Next, the prediction module 123 determines whether N is zero (step S53). That is, the prediction module 123 determines whether or not there is a controlled device.

  When it determines with N being zero (step S53; Yes), the prediction module 123 transfers a process to step S58. On the other hand, when it determines with N not being zero (step S53; No), the prediction module 123 substitutes 1 to the variable n (step S54). The variable n is a number assigned for convenience to the controlled device in operation.

  Next, the prediction module 123 predicts the power consumption amount El (n) of the nth controlled device in a specified period after the current time based on the transition pattern of the power consumption after activation of the controlled device ( Step S55). Specifically, the prediction module 123 reads “operation start time” of the operating device information 131 and “average power consumption”, “average operating time”, “rise pattern”, and “rise time” of the device information database 61. Thus, the power consumption El (n) is predicted from the read information.

  Specifically, when the time from the operation start time Ts to the current time Tn is longer than the rise time Tt, El (n) = Pa × ( The power consumption amount El (n) is calculated by the arithmetic expression of (Tk−Tn). In FIG. 16, a region corresponding to the power consumption amount El (n) calculated in this way is indicated by hatching.

  When the time from the operation start time Ts to the current time Tn is shorter than the rise time Tt, the power consumption El (n) is calculated using the average power consumption Pa and the end time Tk of the specified time. . However, when the rising pattern is the A pattern, the power consumption El (n) is calculated assuming that the power consumption during the rising time is equal to twice the average power consumption Pa, and when the rising pattern is the C pattern, the rising power The power consumption amount El (n) is calculated assuming that the power consumption during the time is equal to ½ times the average power consumption Pa.

  That is, the power consumption El (n) of the controlled device whose rising pattern is the A pattern is El (n) = (Pa × 2) × (Tt− (Tn−Ts)) + Pa × (Tk− (Tn + (Tt) -(Tn-Ts)))). In FIG. 17, a region corresponding to the power consumption amount El (n) calculated in this way is indicated by hatching.

  Next, the prediction module 123 determines whether or not the variable n is equal to N (step S56).

  If it is determined that the variable n is not equal to N (step S56; No), the prediction module 123 adds 1 to the variable n (step S57), and repeats the processing after step S55.

  On the other hand, when it determines with the variable n being equal to N (step S56; Yes), the prediction module 123 calculates the prediction power consumption of the controlled apparatus in a regulation period (step S58). Specifically, the prediction module 123 sequentially calculates the standby power predicted value Ew calculated in step S51 and the integrated value Ep up to the current time of the power consumption measured by the measuring device 20 in the specified period, in step S55. The predicted power consumption Ef is calculated by adding the N power consumptions El (n). That is, the prediction module 123 calculates the predicted power consumption Ef according to an arithmetic expression of Ef = Ep + Ew + ΣEl (n).

  Next, the prediction module 123 predicts the transition of the integrated value of power consumption by the controlled device from the current time to the end time of the specified period (step S59). Specifically, the prediction module 123 predicts a transition in which the integrated value increases at a certain rate from the power consumption amount Ep at the current time and reaches the power consumption amount Ef.

  Next, as illustrated in FIG. 18, the prediction module 123 refers to the “operation type” of the operation device information 131 and acquires the number M of short-term operation devices in operation (step S <b> 510).

  Next, the prediction module 123 determines whether or not M is zero (step S511). That is, the prediction module 123 determines whether or not there is a short-term operating device in operation.

  When it determines with M being zero (step S511; Yes), the prediction module 123 transfers a process to step S516. On the other hand, when it determines with M not being zero (step S511; No), the prediction module 123 substitutes 1 to the variable m (step S512). The variable m is a number assigned for convenience to a short-term operating device in operation.

  Next, the prediction module 123 predicts the power consumption amount Es (m) of the m-th short-term operating device in a specified period after the current time (step S513). Specifically, the prediction module 123 refers to the operation start time Ts of the operation device information 131 and the average power consumption Pa and the average operation time Ta of the device information database 61, and Es (m) = Pa × Ta. The power consumption amount Es (m) is calculated according to the following equation.

  Next, the prediction module 123 determines whether or not the variable m is equal to M (step S514).

  When it determines with the variable m not equal to M (step S514; No), the prediction module 123 adds 1 to the variable m (step S515), and repeats the process after step S513.

  On the other hand, when it determines with the variable m being equal to M (step S514; Yes), the prediction module 123 calculates the estimated power consumption of the short-term operation apparatus in a regulation period (step S516). Specifically, the prediction module 123 calculates the predicted power consumption ES by adding the M power consumptions Es (m) sequentially calculated in step S513. That is, the prediction module 123 calculates the predicted power consumption ES according to the arithmetic expression of ES = ΣEs (m). The predicted power consumption amount ES corresponds to the amount of power that is supplied from the commercial power supply 70 to the short-term operation device from the current time to the end time of the specified period.

  Thereafter, the process executed by the control unit 120 returns from the prediction process to the control process shown in FIG.

  Next, details of the threshold update process (step S6) shown in FIG. 11 will be described with reference to FIG.

  In the threshold update process, the threshold update module 124 first acquires the maximum demand power Eh stored in the server 60 (step S61).

  Next, the threshold update module 124 acquires the predicted power consumption Ef, ES from the storage unit 130 (step S62).

  Next, the threshold update module 124 calculates the control target value Eh2 of the controlled device from the maximum demand power Eh acquired in step S61 and the predicted power consumption ES of the short-term operating device (step S63). Specifically, the threshold update module 124 calculates the control target value Ph2 by subtracting the predicted power consumption ES of the short-term operating device from the maximum demand power Eh according to the arithmetic expression of Eh2 = Eh−ES.

  Next, the threshold update module 124 calculates and updates a threshold from the predicted power consumption Ef acquired in step S62 and the control target value Eh2 calculated in step S63 (step S64). Thereafter, the process executed by the control unit 120 returns from the threshold update process to the control process shown in FIG.

  Calculation of the threshold when the number M of short-term operating devices in operation is zero will be described with reference to FIG. In this case, since M is zero, the control target value Eh2 is equal to the maximum demand power Eh. That is, the equation Eh = Eh2 holds. In the example shown in FIG. 20, the electric devices 31, 32, and 34 that are controlled devices are operating at the current time Tn. At this time, the prediction module 123 obtains the predicted power consumption Ef. Then, the threshold update module 124 calculates the maximum demand power Eh and the slope of the line L2 between the coordinates (Tn, Ep) and the coordinates (Tk, Ef) from the current time Tn to the end time Tk of the specified period. A line L3 indicating the threshold value is calculated. However, the line L1 in FIG. 20 indicates the integrated value of the measurement values obtained from the measurement device 20.

  In the line L3 calculated in this way, when the electric device 30 operating at the current time continues to operate, the total power consumption of the electric device 30 in the specified period exceeds the maximum demand power as the target value. Indicates a threshold value that does not exist. That is, if the total power consumption exceeds a threshold value by any point in time within the specified period, if the power consumption is not suppressed by controlling any of the electrical devices 30 operating at that time, the specified period It is expected that the total power consumption will exceed the maximum demand power.

  Line L2 is the transition predicted in step S59 in FIG. 15, and the transition from the current time Tn to the end time Tk of the integrated value of power supplied from the commercial power supply 70 to the controlled device and consumed. It corresponds to. The line L3 corresponds to the line L2 moved upward by (Eh−Ef). In other words, the line L3 indicating the threshold value as the sum obtained by adding the predicted transition to the difference (Eh−Ef) obtained by subtracting the value Ef at the end time Tk from the maximum demand power Eh. Is derived.

  Next, calculation of a threshold when there is a short-term operating device in operation will be described with reference to FIG. In this case, the inequality Eh2 <Eh is established. In the example shown in FIG. 21, the electrical device 33 as a short-term operating device starts operating between time Tn and time T (n + 1). Since the power consumption amount Ep until the current time T (n + 1) exceeds the threshold obtained in FIG. 19, the device suppression module 121 suppresses the power consumption of the controlled device having a large suppression priority. The prediction module 123 calculates the predicted power consumption Ef, ES, and the threshold update module 124 calculates the control target value Eh2. Then, the threshold update module 124 defines from the current time T (n + 1) based on the control target value Eh2 and the slope of the line L5 between the coordinates (T (n + 1), Ep) and the coordinates (Tk, Ef). A line L6 indicating a threshold up to the end time Tk of the period is calculated.

  The line L5 is the transition predicted in step S59 in FIG. 15, and the integrated value of the power supplied from the commercial power supply 70 to the controlled device and consumed is from the current time T (n + 1) to the end time Tk. It corresponds to the transition until. The line L6 corresponds to the line L5 moved upward by (Eh2-Ef). In other words, the sum obtained by adding the predicted transition to the difference (Eh2−Ef) obtained by subtracting the predicted power consumption ES from the predicted power consumption ES and the value Ef at the end time Tk from the predicted transition. As a result, a line L6 indicating the threshold is derived.

  When the integrated value of the total power exceeds the maximum demand power Eh within the specified period, the control unit 120 refers to the contract power table stored in the server 60 and sets a new maximum demand power Eh.

  As described above, the control device 10 according to the present embodiment controls a controlled device that operates by consuming power over a longer time than a predetermined time in the electric device 30. In general, it can be said that the start and stop of such a long-term operating device has a small influence on the comfort of the resident of the house 200. For this reason, power consumption can be suppressed without impairing comfort.

  Moreover, the control apparatus 10 controlled the controlled apparatus with a small ratio of remaining operation time preferentially over other controlled apparatuses, and suppressed power consumption. It is considered that the start / stop of the controlled device having a small ratio of the remaining operation time has a smaller influence on the comfort of the resident. For this reason, power consumption can be effectively suppressed without impairing comfort.

  Moreover, the control apparatus 10 selected the to-be-controlled device which cancels | releases suppression of power consumption based on the parameter | index regarding comfort and operation time. Thereby, suppression of the power consumption with respect to the electric equipment required for a user can be prevented as much as possible.

  Moreover, the control apparatus 10 updated the threshold value by adding the transition of the power consumption amount of the controlled device to the sum obtained by subtracting the predicted power consumption amounts ES and Ef from the maximum demand power as the target value. As a result, a threshold is set that allows the user to use the device freely as long as the currently operating device continues to operate and the total value of the total power during the specified period does not exceed the maximum demand power. can do.

  Further, the control device 10 calculates the predicted power consumption based on the transition pattern of the power consumption after activation of the controlled device. For this reason, it is possible to accurately calculate the predicted power consumption and accurately control the power consumption.

Embodiment 2. FIG.
Next, the second embodiment will be described focusing on the differences from the first embodiment. In addition, about the structure which is the same as that of the said Embodiment 1, or equivalent, while using an equivalent code | symbol, the description is abbreviate | omitted or simplified. As shown in FIG. 22, the energy management system 100 according to the present embodiment is different from that according to the first embodiment in that it includes a power generation device 81, a power conditioner 82, and a power conversion device 83. .

  The power generation device 81 is a device that generates power using, for example, a solar power generation panel, a wind power generation device, or a fuel cell. The power generator 81 generates DC power. The power conditioner 82 is a device that converts the DC power generated by the power generator 81 into AC power and supplies the AC power to the house 200.

  The power conversion device 83 is connected to the commercial power source 70, the power conditioner 82, and the electric devices 31 to 39 via a power line. The power conversion device 83 determines the amount of power supplied to each of the electrical devices 31 to 39 from the power generation device 81 and the commercial power supply 70. In addition, the power conversion device 83 is connected to the control device 10 via a communication line, and transmits information regarding the determined power supply amount to the control device 10.

  Then, the apparatus suppression process which concerns on this Embodiment is demonstrated using FIG. The device suppression process shown in FIG. 23 is different from that according to the first embodiment in that step S35a is executed subsequent to step S34.

  In step S <b> 35 a, the device suppression module 121 determines whether or not the predicted value of the total amount of purchased power during the specified period has become equal to or less than the target value as a result of suppressing power consumption. This total amount of electric power purchased is equal to a value obtained by subtracting the amount of electric power generated by the power generator from the total amount of electric power consumed by the electrical device 30. In other words, the total amount of power purchased is equal to the amount of power consumed by being supplied from the commercial power supply 70 to the electrical device 30.

  Subsequently, the suppression release processing according to the present embodiment will be described with reference to FIG. The suppression release process shown in FIG. 24 is different from that according to the first embodiment in that step S44a is executed subsequent to step S43.

  In step S44a, the suppression release module 122 adds the power consumption of the selected combination of devices to the predicted power consumption, and determines whether or not the value obtained by subtracting the power generated by the power generation device 81 is equal to or greater than a threshold value. In other words, the suppression release module 122 determines whether or not the power supplied from the commercial power supply 70 and consumed by the electrical device 30 when the suppression is released is equal to or greater than a threshold value.

  As described above, the control device 10 according to the present embodiment executes suppression of power consumption in consideration of generated power. Thereby, power consumption can be suppressed while effectively using generated power.

Embodiment 3 FIG.
Subsequently, the third embodiment will be described focusing on differences from the above-described second embodiment. In addition, about the structure same or equivalent to the said Embodiment 2, while using an equivalent code | symbol, the description is abbreviate | omitted or simplified. The energy management system 100 according to the present embodiment is different from that according to the first embodiment in that it includes a power storage device 90 as shown in FIG.

  The power storage device 90 is, for example, a battery mounted on an electric vehicle, and is connected to the power conversion device 83 via a power line. The power storage device 90 stores the power supplied from at least one of the commercial power supply 70 and the power generation device 81 and supplies the stored power to the electric device 30 via the power conversion device 83.

  Subsequently, a control process according to the present embodiment will be described with reference to FIG. This control process is related to the second embodiment in that the determination of step S8a is executed when the determination of step S2 is affirmed, and step S9a is executed when the determination of step S8a is affirmed. Is different.

  In step S8a, control unit 120 determines whether or not the remaining amount of power stored in power storage device 90 exceeds the amount by which the integrated value of power consumption exceeds the threshold. That is, the control unit 120 determines whether or not the power supplied from the commercial power supply 70 to the electric device 30 can be suppressed to a threshold value or less by supplying power from the power storage device 90.

  When determination of step S8a is denied (step S8a; No), the control part 120 performs an apparatus suppression process, without making the electrical storage apparatus 90 supply electric power. On the other hand, when the determination in step S8a is affirmed (step S8a; Yes), the control unit 120 does not execute the device suppression process, and causes the power storage device 90 to receive power corresponding to the excess used in the determination in step S8a. Is supplied to the home (step S9a).

  Thereby, it is possible to suppress the total power consumption that is supplied and consumed from the commercial power supply 70 to the electrical device 30 by effectively using the remaining power amount without suppressing the power consumption of the electrical device 30.

  Note that there is an upper limit for power supply from the power storage device 90 via the power conversion device 83, and if the power storage device 90 supplies the maximum amount of power and the excess cannot be compensated, Even if this is sufficient, it is necessary to execute device suppression processing.

  In addition, some power storage devices 90 have a minimum capacity value, and even when the remaining power storage amount is sufficient to compensate for the excess amount, the minimum capacity value is subtracted from the remaining power storage amount. May be insufficient. Even in this case, it is necessary to execute the device suppression process even if the remaining amount of power storage is sufficient.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.

  For example, the energy management system 100 may be configured without the storage unit 130, and the server 60 may store the operating device information 131 and the suppression device information 132. Further, the server 60 may be omitted to constitute the energy management system 100, and the storage unit 130 may store the device information database 61. When the server 60 is omitted and the network connection function of the control device 10 is also omitted, the control device 10 cannot acquire the contract power table of the power company via the network 50. At this time, the contract power table may be input from the terminal 40.

  Further, in the above embodiment, when the power consumption exceeds the maximum demand power, the maximum demand power stored in the server 60 is automatically updated. Also good.

  Further, the prediction module 123 predicts that the integrated value of power consumption by the controlled device increases at a certain rate, but is not limited thereto. For example, the prediction module 123 may predict the transition based on the past operation history of the controlled device, or when the operation of the controlled device is predicted to end before the end time of the specified period. May predict the transition in consideration of the end of the operation.

  Further, the threshold update module 124 calculates a threshold that changes with time as indicated by a line L3 in FIG. 20 and a line L6 in FIG. 21, but the present invention is not limited to this. Since the control process shown in FIG. 11 is executed every minute, the threshold update module 124 may calculate only the threshold referred to in the next control process. For example, referring to FIG. 20, if the current time is Tn, only the value at time T (n + 1) of the line L3 is calculated as a threshold value used in the next control process, and when the current time becomes T (n + 1). Only the value at time T (n + 2) of line L3 may be calculated as the threshold value used in the next control process.

  The functions of the control device 10 according to the above-described embodiment can be realized by dedicated hardware or by a normal computer system.

  For example, the program P1 stored in the auxiliary storage unit 13 of the control device 10 is stored in a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk) or the like. And distributing the program P1 to the computer, it is possible to configure an apparatus that executes the above-described processing.

  Further, the program P1 may be stored in a disk device included in a server device on a communication network represented by the Internet, and may be downloaded onto a computer, for example, superimposed on a carrier wave.

  The above-described processing can also be achieved by starting and executing the program P1 while transferring it through the communication network.

  Further, the above-described processing can also be achieved by executing all or part of the program P1 on the server device and executing the program P1 while the computer transmits / receives information related to the processing via the communication network. .

  Note that when the above functions are realized by sharing an OS (Operating System) or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. Alternatively, it may be downloaded to a computer.

  The means for realizing the function of the control device 10 is not limited to software, and part or all of the means may be realized by dedicated hardware (circuit or the like).
