Description

  The present invention relates to an incentive type demand response system.

  In recent years, there has been a strong demand for energy usage management in accordance with legal revisions caused by the global warming issue. Attempts have been made to introduce demand response (hereinafter referred to as DR) that suppresses peak power consumption by providing services such as paying (hereinafter referred to as incentive).

  With regard to such power DR, incentive calculation methods corresponding to power reduction targets have been proposed from the standpoint of power suppliers for the purpose of optimizing incentives to be paid to consumers (see Patent Document 1).

JP 2006-12273 A

  Incentives by DR are composed of basic rewards and pay-as-you-go rewards. The basic remuneration is a fixed remuneration obtained when contracting with the DR, and the pay-as-you-go remuneration is a success remuneration (variable remuneration) for performing the DR. Therefore, the incentive due to DR varies.

  The background of the necessity (importance) of incentives is to alleviate residents' dissatisfaction by suppressing facility power such as air conditioning with the implementation of DR. However, when the incentives that vary as described above are distributed to the residents, if the amount of distribution is small, the residents cannot realize the distribution of the incentives.

  Normally, incentives from electric power companies are paid to the owner of the building, so even if the incentive can be properly calculated as in the technique disclosed in Patent Document 2, it is distributed to the residents. If there are fewer incentives, it will be difficult to mitigate and eliminate residents' dissatisfaction with the decline in comfort associated with DR. In other words, the satisfaction of the resident due to the incentive is not satisfied, the DR is dissatisfied, and it is difficult to continue the DR.

  The present invention has been made to solve the above-described problems, and provides a demand response system that allows residents to feel the distribution of incentives and can reduce the possibility of continuation of demand response. The purpose is to do.

[Principle of Invention 1]
The inventor proposed to change the baseline of the setting value of the target device of the DR in a direction to alleviate the power reduction based on the incentive as a method of allocating the incentive to residents (Japanese Patent Application No. 2006-2006). 086765). However, in this method, depending on the situation, a set value change of, for example, about 0.1 ° C. may occur. The reason is that the proposed distribution method is a method that considers equality to residents.

  On the other hand, in terms of the resident's feeling, always or equality is not necessarily a priority, and the cumulative type like the so-called point method (result is not always), or the fair opportunity type like the lottery method (result is Non-equality) may also be employed.

  Then, the inventor adopts a threshold value that allows the resident to feel the environmental change in the setting value change according to the incentive, and if the incentive is less than a certain threshold value, it is carried over to the next DR without being distributed ( Carry over), and when it becomes possible to change the set value that satisfies the threshold value, it came to light that the operation (cumulative type and fair opportunity type) that distributes incentives to residents is effective.

[Principle of Invention 2]
When the incentive is carried over as described above, the resident feels that the incentive by DR has not been obtained. In addition, when the incentive can be received, it may not be recognized and may be missed. This disappoints the expectation of incentive reduction and makes it difficult to alleviate and eliminate the dissatisfaction with the decrease in comfort associated with the implementation of DR.

  Therefore, the inventor will notify the resident in advance that the incentive will be carried over next time, notify the resident that the incentive has been carried over, and carry over until the incentive is returned. It was thought that it was effective to notify the residents of the expected number of times. Thereby, the rise of the dissatisfaction with the resident's DR can be suppressed, and the possibility that it is difficult to continue the DR can be reduced.

  If it is automatically carried over until the cumulative value of the incentive exceeds the threshold value, the resident may be dissatisfied with having not obtained the DR incentive. The inventor noticed that such dissatisfaction was caused by “asymmetry of information” between the building owner and residents. Therefore, we came up with the idea that “information asymmetry” can be eliminated by providing information on the status of carry-over of incentives to residents.

[First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a DR system according to the first embodiment of the present invention. The present embodiment is an example corresponding to Principle 1 of the invention described above. In the present embodiment, an example in which the room temperature setting value of the air conditioner is used as the control setting value of the target device of the DR will be described. However, as an example of the setting value, the humidity setting value of the air conditioner or the radiation air conditioning system Air conditioning setting values such as the temperature setting value of the radiant panel used in the above are conceivable.

The DR system includes a monitoring device 1 that controls DR target devices and an environment improvement setting device 2.
The environment improvement setting device 2 calculates the incentive distribution amount for each system based on the current DR based on the incentive amount paid to the customer as consideration for the DR and the reduction capacity for each system, and calculates the incentive allocation amount and the previous DR. It is consumed by the system-specific incentive calculation unit 20 that calculates the total amount of the carried-in incentive distribution amount for each system, and by changing the control setting value of the target device in the direction of mitigating power reduction during the setting value change period. The set value change width calculation unit 21 for calculating the change width of the control set value for each system and the change width for each system calculated by the set value change width calculation unit 21 are set in advance so that the total cost matches the total cost. Carryover determination unit 22 (carryover processing) for determining whether or not the set carryover threshold for each system is exceeded. ) And the control setting value of the target device of the relevant system in the set value changing period only for the system whose control setting value change range exceeds the corresponding threshold value, The setting change unit 23 that gives an instruction to the monitoring device 1 so as to change the power reduction only, and the incentive accumulation unit for each system that stores the incentive distribution amount carried over from the previous DR for each system 24, target system facility information, which is necessary facility information when calculating the cost for changing the set value, incentive amount information indicating the amount to be paid by the electric power company by performing DR, and when performing DR Among the reduction capacity for each system, which is the power that each system reduces, the set value change period information that specifies the set value change period, and the incentive that the owner obtains System-based incentive reduction rate information indicating the system-based incentives reduction rate for reducing the person, and a storage unit 25 for storing in advance a system-based carryover threshold.

  FIG. 2 is a flowchart for explaining the operation of the DR system of the present embodiment. First, the system-specific incentive computing unit 20 of the environment improvement setting device 2 operates with information on the incentive amount paid to the consumer from the electric utility as a consideration for the DR and the electric power supplied from the electric utility to the consumer. Among the devices, information on the reduction capacity by system in which the reduction capacity that is the power to be reduced by the target device of the DR is determined for each system of the target device from the storage unit 25, and the system is carried over from the previous DR Information on different incentive allocation amounts is acquired from the system-specific incentive storage unit 24, and based on the acquired information, the total amount of the incentive allocation amount based on the current DR and the incentive allocation amount carried over from the previous DR Is calculated for each system (step S1 in FIG. 2).

  The system refers to a group in which DR target devices are divided according to some standard. As an example of a system, there are each floor of a building, for example. It is also conceivable that a plurality of buildings are targeted for DR and each building is divided into different systems. The electric utility pays incentives as consideration for the electric power (total reduction capacity) that demands reduction from consumers. The customer may determine in advance the reduction capacity for each system in which the total reduction capacity is allocated for each system, and register the information on the reduction capacity for each system in the storage unit 23.

  Here, as an example, the total incentive amount is 8000 yen, the system is 3 systems of A, B and C, the reduction capacity of the A system is 5 kW, the reduction capacity of the B system is also 5 kW, and the reduction capacity of the C system 10 kW. Here, in order to preferentially distribute incentives to a system that bears a large amount of reduction capacity, the incentive allocation amount by the current DR is determined using the distribution ratio of reduction capacity by system. In the case of the above conditions, the allocated amount is as shown in Table 1 below.

  As is clear from Table 1, the reduction capacity ratio is a percentage obtained by dividing the reduction capacity by system by the sum of the reduction capacities by system. Part of the incentive is paid to the customer, and this amount changes depending on the amount carried over from the previous DR, so the total incentive allocation amount is the amount shown in Table 1. Then, it is multiplied by the system-specific incentive return rate registered in advance in the storage unit 25, and further added to the system-specific incentive distribution amount carried over from the previous DR.

The total incentive amount paid by the electric power company is TM [yen], the reduction capacity ratio of the target system is R1 [%], the incentive return rate by system is R2 [%], and each system is carried over from the previous DR When the incentive distribution amount is MB [yen], the system-specific incentive calculation unit 20 calculates the total incentive distribution amount M [yen] for each system using equation (1).
M = MA + MB
= {TM × (R1 / 100) × (R2 / 100)} + MB (1)

  The first term on the right side in this equation (1), that is, MA = {TM × (R1 / 100) × (R2 / 100)} is the incentive distribution amount for each system by the current DR.

  Next, the setting value change width calculation unit 21 of the environment improvement setting device 2 changes the control setting value of the target device (in the example of the present embodiment, the room temperature setting value of the air conditioner) in a direction that reduces power reduction. The change amount of the control set value is calculated for each system so that the cost consumed by the system and the system-specific incentive calculation unit 20 match the system-specific incentive distribution amount M calculated in step S1 (step S2 in FIG. 2).

Here, an example of a simple calculation method of the change width ΔT _sp [K] of the room temperature set value T _sp is shown. The system-specific incentive calculation unit 20 calculates the system-specific incentive distribution amount M [yen], the outside air introduction amount of the target system G _OA [m ³ / h], and the known specific gravity of _air ρ _air [kg / m ³ ] , C _air [kJ / kg · K], known specific heat of _air , D [yen / kJ] for a metered charge of energy used, H [h] for a predetermined set value change period, When the known heat source performance coefficient indicating the energy consumption efficiency (Coefficient Of Performance) of the target device (air conditioner) is COP [−], the change width ΔT _sp [K] of the room temperature set value T _sp of the target system is expressed by the equation (2). ).
ΔT _sp = M / (G _OA ρ _air C _air DH / COP) (2)

Values other than the incentive distribution amount M for each system used in the equation (2) may be registered in the storage unit 25 in advance. The outside air introduction amount G _OA of the target system varies depending on the conditions such as the season, but a typical value based on the past air conditioning operation results may be registered in the storage unit 25 in advance. Further, the metered charge D of the energy used can be obtained from the metered charge of the electric power determined by the electric power company. The length H of the set value change period can be obtained from the set value change period information registered in the storage unit 25. Equation (2) calculates the energy consumed by the air conditioner by changing the control setting value (for example, the room temperature setting value), calculates the cost from this energy, and the cost and the incentive distribution amount for each system match. The change width of the set value is calculated.

  Subsequently, the carryover determination unit 22 of the environment improvement setting device 2 sets the carryover threshold for each system in which the change range of the control set value calculated by the set value change range calculation unit 21 in step S2 is registered in the storage unit 25 in advance. It is determined for each system whether or not it exceeds (step S3 in FIG. 2). As the carry-over threshold, a value that allows a resident to feel an environmental change (in the example of the present embodiment, for example, 1 ° C. is a threshold value for changing a room temperature setting value), or a change width that can be input to an air conditioner. A value may be set in advance for each system.

  The setting change unit 23 of the environment improvement setting device 2 changes the set value specified by the set value change period information only for the system for which the change width of the control set value has been determined to exceed the corresponding carry-over threshold for each system. In the period, in the monitoring apparatus 1, the control setting value of the target device of the system is changed so as to reduce the power reduction by the amount of change determined by the setting value change width calculation unit 21 for the system. An instruction is given to it (step S4 in FIG. 2).

  In the setting value change period, the monitoring device 1 sets the control setting value of the target device of the system instructed to be changed from the setting changing unit 23 of the environment improvement setting device 2 by the change width instructed from the setting changing unit 23. Change to mitigate power savings. The control set value before the change is set by a building manager, for example. Moreover, the monitoring apparatus 1 returns the control setting value of the target apparatus of each system | strain to the value before a change automatically after completion | finish of a setting value change period or according to the instruction | indication from the setting change part 23. FIG. That is, the setting change unit 23 may give an instruction to the monitoring device 1 so that the changed control setting value is returned to the value before the change after the end of the setting value change period.

  Furthermore, the monitoring device 1 limits the operation of the target device of each system (for example, temporarily powers off) in response to an instruction from a higher-order demand management system (not shown), for example, during the DR target period. Realize power reduction according to the above-mentioned system-specific reduction capacity.

FIG. 3 is a diagram for explaining an example of setting value change in the present embodiment. Here, an example is shown in which the room temperature set value is changed to a direction that reduces power reduction (a direction in which the room temperature set value is lowered) during cooling. In FIG. 3, T _sp indicates a room temperature setting value before incentive allocation (for example, a room temperature setting value determined by a building manager), T _sp ′ indicates a room temperature setting value after incentive allocation, and E indicates power before incentive allocation. The consumption amount E ′ indicates the power consumption amount after incentive allocation.

  As is apparent from FIG. 3, in the present embodiment, the power consumption of the consumer is increased by changing the set value. An increase in the power consumption baseline can also be expected to facilitate the power reduction by DR. In addition, since the baseline is raised based on the incentive amount to the end, the cost does not increase for the consumer compared to before the introduction of DR.

  When the change in the control setting value is performed for the system for which it is determined that the change width of the control setting value exceeds the corresponding carry-over threshold, the carry-over determination unit 22 stores the change in the control setting value in the incentive accumulation unit 24 for each system. The incentive distribution amount MB of the relevant system is cleared to 0 (step S5 in FIG. 2).

  Further, the carry over determination unit 22 does not change the control set value for the system for which it is determined that the change width of the control set value does not exceed the corresponding carry over threshold, and the system-specific incentive calculation unit 20 performs the step It is decided to carry over the incentive distribution amount MA of the system by the current DR calculated in S1 to the next DR, and the incentive distribution amount MB of the system stored in the system-specific incentive storage unit 24 is stored in the incentive distribution amount MA. Is added to the cumulative incentive distribution amount MB of the system (step S6 in FIG. 2).

  Two calculation examples of this embodiment are shown below.

[Calculation Example 1]
In this calculation example 1, the incentive distribution amount MA by the current DR is 2000 yen, the incentive distribution amount MB of the system stored in the system-specific incentive storage unit 24 is 3000 yen, and the total incentive distribution amount 5000 is set The change width of the control set value (room temperature set value) of the system calculated by the value change width calculation unit 21 is 0.5 ° C., and the carry-over threshold value of the system previously registered in the storage unit 25 is 1.0 ° C. To do.

  In the case of this calculation example 1, since the change width of the control set value does not exceed the carryover threshold, the control set value of the system is not changed, and the incentive distribution of the system stored in the system-specific incentive accumulation unit 24 is performed. The incentive distribution amount MA by this time DR = 2000 yen is added to the amount MB = 3000 yen. As a result, the cumulative incentive distribution amount MB of the system is updated to 5000 yen.

[Calculation Example 2]
In this calculation example 2, the incentive distribution amount MA by the current DR is 5000 yen, the incentive distribution amount MB of the system stored in the system-specific incentive storage unit 24 is 5000 yen, and the set value from the total incentive distribution amount 10000 yen The change width of the control set value (room temperature set value) of the system calculated by the change width calculation unit 21 is 1.1 ° C., and the carry-over threshold value of the system previously registered in the storage unit 25 is 1.0 ° C. .

  In the case of this calculation example 2, since the change width of the control set value exceeds the carryover threshold, the control set value of the system is changed by 1.1 ° C., and the system of the system stored in the system-specific incentive accumulation unit 24 is changed. Change the incentive allocation amount MB = 5000 yen to 0 yen.

  As described above, in this embodiment, DR incentives are distributed in the form of a return of comfort to the residents of the building where the target device is installed, thereby reducing residents' dissatisfaction due to the implementation of DR. Can do. In this embodiment, when the change width of the control setting value according to the incentive allocation amount is equal to or less than the carryover threshold, the control setting value is not changed, and the incentive allocation amount is carried over to the next and subsequent DRs. By performing the setting value change when the change width of the setting value exceeds the carry-over threshold, it is possible to realize an operation in which the resident can realize the distribution of incentives. Thereby, it can be expected that the possibility that the DR contract can be continued is improved.

  When the set value change period starts in the middle of the DR target period, the power consumption baseline for evaluating the DR reduction amount is calculated based on the results before the set value change. It will be the result of blocking. Therefore, the set value change period may include the DR target period, and the set value change period may start before the DR target period. If the set value change period starts before the target period of DR, the baseline of power consumption for evaluating the reduction amount of DR is calculated based on the actual power consumption during the set value change period. However, the amount of reduction will not decrease.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. The present embodiment is an example corresponding to Principle 2 of the invention described above. FIG. 4 is a block diagram showing the configuration of the DR system according to the second embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. In the present embodiment, an example in which the room temperature setting value of the air conditioner is used as the control setting value of the target device of the DR will be described. However, as in the first embodiment, other examples of the setting value include air conditioning Air conditioning setting values such as the humidity setting value of the machine and the temperature setting value of the radiation panel used in the radiation air conditioning system are conceivable.

The DR system of the present embodiment includes a monitoring device 1, an environment improvement setting device 2a, and a carry over information notification device 3.
The environment improvement setting device 2a of the present embodiment includes a system-specific incentive calculation unit 20, a set value change width calculation unit 21, a carryover determination unit 22, a setting change unit 23, a system-specific incentive accumulation unit 24, The storage unit 25 and a system-specific carry-over information notification unit 26 that notifies the resident of the carry-over status of the incentive through the carry-over information notification device 3.

  FIG. 5 is a flowchart for explaining the operation of the DR system of the present embodiment. Since the processing of steps S1 to S6 in FIG. 5 is as described in the first embodiment, description thereof is omitted.

  The carry-over information notification unit 26 for each system of the environment improvement setting device 2a determines carry-over when the change width of the control setting value does not exceed the carry-over threshold and the incentive allocation amount MA by the current DR is carried over to the next DR. When the cumulative incentive distribution amount MB of the system stored in the system-specific incentive storage unit 24 is updated for the system determined by the unit 22 (step S6 in FIG. 5), the current date and time is from the set value change period. In the previous case, the carry-over information notification device 3 notifies the resident of the system that the incentive will be carried over next time (step S7 in FIG. 5).

At this time, the incentive distribution amount MA of the system according to the current DR and the cumulative incentive distribution amount MB of the system may be notified together.
As a notification method to the resident, for example, among the carryover information notification devices 3 installed for each system, the carryover information notification device for the system determined to carry over the incentive distribution amount MA by the current DR to the next DR There is a method of displaying information on 3 or outputting sound to the carry-over information notification device 3.

  In addition, the e-mail address of the employee's terminal in the building is registered in advance in the storage unit 25 for each system, and the incentive distribution amount MA by the current DR is addressed to the employee's terminal determined to carry over to the next DR. The mail may be transmitted from the carryover information notification device 3.

  FIG. 6 shows a display example of information displayed on the screen 30 of the carryover information notification device 3 by the process of step S7. In this example, the resident is notified of the plan to carry over the incentive (carry over), the incentive allocation amount MA (for today) by the current DR, and the cumulative incentive allocation amount MB.

  Further, when the set value change period is reached, the carry-by-system-by-system notification unit 26 notifies the residents of the system through the carry-over information notification device 3 that the incentive has been carried over next time (step S8 in FIG. 5). At this time, the cumulative incentive distribution amount MB of the system may be notified together. The notification method to the resident is as described above.

  FIG. 7 shows a display example of information displayed on the screen 30 of the carryover information notification device 3 by the process of step S8. In this example, the resident is notified of carrying over the incentive and the cumulative incentive distribution amount MB.

  Further, the carry-over information notification unit 26 for each system, for the system determined to carry over the incentive allocation amount MA by the current DR to the next DR, the average value of the incentive allocation amount MA of the system and the current It is also possible to calculate the estimated number of carry-overs until the incentive is returned from the current cumulative incentive allocation amount MB, and to notify the residents of the system through this carry-over information notification device 3. Good (step S9 in FIG. 5). At this time, the incentive distribution amount MA of the system according to the current DR and the cumulative incentive distribution amount MB of the system may be notified together.

  FIG. 8 is a diagram for explaining a method of calculating the expected number of carry-over until the incentive is reduced in the present embodiment. As described above, for the system that is determined to carry over the incentive allocation amount MA by the current DR to the next DR, the incentive allocation amount MA of the system by the current DR and the system stored in the system-specific incentive accumulation unit 24 If the total incentive distribution amount M with the cumulative incentive distribution amount MB is known, it is possible to calculate the change range of the control setting value of the current system by the method described in step S2.

Therefore, for the system determined to carry over the incentive allocation amount MA by the current DR to the next DR, the cumulative incentive allocation amount updated in the process of step S6 is MB ′ (MB ′ = M = MA + MB), If the average value of the incentive allocation amount MA of the system is MAave, the total incentive allocation amount Mn used when calculating the change range of the control setting value n times after the present can be obtained by the following equation. . From this total incentive distribution amount Mn, it is possible to predict the change range of the control set value after n times by the method described in step S2.
Mn = MB ′ + n × MAave (3)

  As is clear from FIG. 8, every time the incentive is carried over, the change width of the control set value increases, so that the change width of the control set value eventually exceeds the corresponding carry-over threshold. For example, in the example of FIG. 8, when the change width of the control setting value after the next time is predicted at the second carry-over time, it can be predicted that the change width of the control setting value after the fifth time exceeds the carryover threshold. Therefore, the expected number of carry-overs until the incentive is returned (including the current carry-over number) is 5.

  FIG. 9 shows a display example of information displayed on the screen 30 of the carryover information notification device 3 by the process of step S9. In the example of FIG. 9, the incentive is scheduled to be carried over, the expected number of carry-overs of the incentive is 5, the incentive allocation amount MA (for today) by the current DR, and the cumulative incentive allocation amount MB And the resident is notified.

  As described above, in the present embodiment, by providing information on the status of carry-over of incentives to residents, it is possible to suppress the rise of residents' dissatisfaction with DR and it may be difficult to continue DR. Can be reduced.

  In addition, in the example of FIG. 6, FIG. 7, FIG. 9, the incentive amount information is notified to the resident. The amount information may or may not be notified according to the circumstances of each site. Good.

[Third Embodiment]
In the first and second embodiments, the change width of the control set value is calculated using the length of the set value change period as a fixed value. However, the present invention is not limited to this. Instead, a set value change period calculation unit may be provided.

In this case, the set value change period calculation unit uses the change amount of the control set value as a fixed value, and the cost consumed by changing the control set value of the target device in a direction to mitigate power reduction and the incentive allocation amount by system The length of the set value change period is calculated for each system so that M matches. For example, if the change width ΔT _sp [K] of the room temperature set value T _sp is set to a preset value, it goes without saying that the length H [h] of the set value change period can be calculated by the equation (2).

  When a set value change period calculating unit is provided instead of the set value change width calculating unit 21, the carry-over threshold for each system registered in advance in the storage unit 25 is not the change width of the control set value but the length of the set value change period. Is set for In this case, the carryover threshold may be set in advance for each system so that the resident can feel the environmental change.

  The carryover determining unit 22 determines for each system whether or not the length of the set value change period calculated by the set value change period calculating unit exceeds the corresponding carryover threshold (step S2 in FIGS. 2 and 5). Equivalent to

  The setting change unit 23 performs the setting value change period of the length calculated by the set value change period calculation unit only for the system in which the length of the set value change period is determined to have exceeded the corresponding carry-over threshold. An instruction is given to the monitoring device 1 so as to change the control setting value of the target device of the system in a direction that reduces the power reduction by a preset change width (step S4 in FIGS. 2 and 5). As described in the first embodiment, the set value change period may include the DR target period and start before the DR target period.

  When the control set value is changed for the system for which the length of the set value change period is determined to exceed the corresponding carry-over threshold, the carry-over determination unit 22 stores the change in the incentive accumulation unit 24 for each system. The incentive distribution amount MB of the system is cleared to 0 (step S5 in FIGS. 2 and 5).

  In addition, the carry over determination unit 22 does not change the control set value for the system for which it is determined that the length of the set value change period does not exceed the corresponding carry over threshold, The incentive distribution amount MA is added to the incentive distribution amount MB of the system stored in the system-specific incentive accumulation unit 24 (step S6 in FIGS. 2 and 5).

  The carry-over information notification unit 26 for each system determines that the length of the set value change period does not exceed the carry-over threshold and the carry-over determination unit 22 determines that the incentive distribution amount MA by the current DR is carried over to the next DR. For the system, the processing described in steps S7 to S9 in FIG. 5 is performed.

  However, in the process of step S9, the length of the set value change period after n times is predicted from the total incentive distribution amount Mn described in Expression (3) according to Expression (2), and the length of the set value change period is calculated. Predicting the point in time when the value exceeds the carryover threshold, the expected number of carry-overs until the incentive is reduced is calculated.

  Other configurations and operations are as described in the first and second embodiments. Thus, the first and second embodiments can be applied to the case where the length of the set value change period is calculated with the change width of the control set value as a fixed value.

  The environment improvement setting devices 2 and 2a described in the first to third embodiments are realized by a computer having a CPU (Central Processing Unit), a storage device, and an interface, and a program for controlling these hardware resources. be able to. The CPU executes the processes described in the first to third embodiments in accordance with a program stored in the storage device.

  The present invention can be applied to an incentive type demand response system.
