Description

  The present invention relates to a power retail management apparatus and a power retail management method.

  Conventionally, power supply to power consumers has been done exclusively by power companies, but with the revision of the Electricity Business Law, it has become possible for power retailers to enter. When a power retailer supplies retail power purchased from a power generator to a plurality of contracted power consumers, the power retailer must adjust the power supply amount so that the supply and the demand are the same amount at the same time. However, unexpected demand fluctuations may occur.

  Therefore, a power retail system has been proposed that adjusts supply and demand so as to be able to cope with unforeseen fluctuations in demand on the day, and secures power necessary for supply to power consumers (see, for example, Patent Document 1). ).

[1. Electricity retail management processing]
First, the power retail management processing according to the embodiment will be described. FIG. 1A is an explanatory diagram of power retail management processing according to the embodiment. In this embodiment, power retail management processing is executed by the power retail system.

  As illustrated in FIG. 1A, the power retail system according to the embodiment includes a plurality of power generation devices, a plurality of smart meters, and a power retail management device. The power generation device, the smart meter, and the power retail management device are connected to each other via a communication network or a dedicated line.

  The transmission / distribution network and the transmission / distribution network management device are managed and operated by the power company CB. In addition, the transmission / distribution network is managed by the transmission / distribution network management device. The power retail management apparatus is managed and operated by a power retailer CA. The electric power retailer CA makes a purchase contract for the generated electric power in advance with a plurality of electric power producers CE. Further, the power retailer CA makes a power retail contract with a plurality of power consumers CD in advance. The power retail management device provides the generated power supplied from the respective power generation devices of the plurality of power producers CE to the plurality of power consumers CD via the power distribution network of the power company CB.

  The plurality of smart meters are respectively provided in a residence or facility of the electric power consumer CD. These smart meters detect the power usage of each of the plurality of power consumers CD, and transmit information on the power usage to the power retail management apparatus via the communication network. The amount of power used is the amount of power consumed by the power consumer CD, and is the amount of power supplied from the transmission / distribution network to the equipment of the power consumer CD.

  In addition, the power retail management apparatus receives information on the amount of power generated by each power generation apparatus from each power generation apparatus via the communication network. The power generation amount is the amount of power supplied from the power generation device to the power transmission and distribution network under the control of the power retail management device. Each power generation device acquires a power total amount adjustment parameter from the power retail management device via a communication network, and the power generation amount output from the power generation device to the power distribution network so as to obtain a power generation amount corresponding to the power total amount adjustment parameter. To control.

  The flow of the power retail management method executed by the power retail system configured as described above will be described with reference to FIG. 1B. FIG. 1B is an explanatory diagram of a power retail management method according to the embodiment. As shown in FIG. 1B, each smart meter transmits information on the amount of power used by each power consumer CD via the communication network (step S1). Each power generator transmits the amount of power generated to the power retail management apparatus via the communication network (step S2).

  The power retail management apparatus calculates a power total amount adjustment parameter for each power generation apparatus based on information for each of the areas EA to ED (hereinafter sometimes collectively referred to as area E) (step S3). In such processing, the power retail management device uses the power generation amount for each power generation device for making the total amount of power generation and the total amount of power usage the same amount at the same time. By calculating based on the power generation amount of the power generation device, a power supply and demand plan is created, and a total power amount adjustment parameter for each power generation device is obtained.

  For example, for each region E, the power retail management device associates the power usage amount of the power consumer CD existing in the same region with the power generation amount of the power generation device. In addition, when the power generation amount is insufficient, the power retail management device associates the shortage of power generation amount with the power generation amount of the power generation devices existing in other regions. In this case, the power retail management apparatus selects, as another area, an area that is closest to the area where the power generation amount is insufficient and has a power generation apparatus that can supply the power generation amount. For example, the power retail management apparatus selects an area where the number of times of crossing the connection points between the transmission and distribution networks of different electric power companies is small as another area, or selects an area where the distance of the power transmission and distribution route is the closest as another area .

  As described above, the power retail management device preferentially associates the power consumer CD and the power generation device in the same region with the supply and demand, and the power generation device that is close to the region for the shortage of the power generation amount. An electric power supply and demand plan is created in association with the electric power consumer CD, and a total electric power amount adjustment parameter for each power generator is obtained.

  Further, when the type of the power generation device is selected by the power consumer CD, the power retail management device further selects the power generation amount for each power generation device in the region E corresponding to the type of the power generation device selected by the power consumer CD. An electric power supply and demand plan is created by calculating based on the state of the electric power generation amount and the electric power usage amount for each power generation, and the total electric power amount adjustment parameter for each power generation device is obtained.

  Next, the power retail management device transmits information on the created power supply and demand plan to the transmission / distribution network management device via the communication network (step S4). The information on the power supply / demand plan is information indicating a schedule of power generation amount to be supplied to the transmission / distribution network and power consumption amount consumed from the transmission / distribution network during a predetermined period TA (eg, 30 minutes).

  Further, the power retail management apparatus transmits the calculated total power amount adjustment parameter to each power generation apparatus via the communication network (step S5). Each power generator adjusts the amount of power generated to be supplied to the power distribution network based on the total power adjustment parameter (step S6).

  As described above, in the power retail management processing according to the embodiment, the power total amount adjustment parameter for each power generation device is set based on the power consumption amount for each region of the power consumer CD and the state of the power generation amount for each region of the power generation device. calculate. Therefore, in this power retail management process, it is possible to appropriately manage the power transmission / distribution path while performing the same amount control simultaneously. For example, it is possible to reduce the transmission / distribution path between the power generation device and the power consumer CD from being long distance, and it is possible to reduce the crossing over the transmission / distribution networks of different power companies CB, and to increase the transmission / distribution cost. Transmission and distribution loss can be reduced.

As shown in FIG. 6, the power generation amount table includes “power generation device ID”, “power generation company”, “region”, “type of power generation device”, “contract power generation amount”, “power generation amount”, “maximum”. Information that associates information on “electric power generation amount” and “power generation fee” is included.

  “Power generation device ID” is identification information of the power generation device 12, and “power generation company” is information of the power generation company CE. The “region” is information on a region where the power generation device 12 is present, and here is a region corresponding to each power transmission and distribution network 4. For example, the region “EA” indicates that the power generation device 12 is connected to the transmission / distribution network 4a, and the region “EB” indicates that the power generation device 12 is connected to the transmission / distribution network 4b. “EC” indicates that the power generation device 12 is connected to the power transmission and distribution network 4c.

  The “contract power generation amount” is a power generation amount set in a contract between the power retailer CA and the power generation company CE. For example, for the power generation device 12 having the power generation device ID “E101” shown in FIG. 6, the minimum contract power generation amount is set to 1 MW / h, and the maximum contract power generation amount is set to 2 MW / h. The minimum contract power generation amount is the minimum power generation amount required from the power retail management device 2 to the power generation device 12, and the maximum contract power generation amount is the power required from the power retail management device 2 to the power generation device 12. This is the upper limit of power generation. The power generator CE having the power generation device 12 that cannot respond to the request for the maximum contract power generation amount from the power retail management device 2 is required to pay a penalty from the power retailer CA.

  The “type of power generation device” is information indicating the type of power generation device 12.

The “electric power generation amount” is information on the electric power generation amount during the predetermined period TA, and is information on the electric power generation amount requested by the control unit 22 to each power generation device 12 using the total electric power adjustment parameter. The “maximum power generation amount” is the maximum power generation amount that can be generated by each power generation device 12 in the next predetermined period TA. “Power generation fee” is a purchase fee of generated power per kilowatt.

[3.4. Adjustment parameter calculation unit 44]
The adjustment parameter calculation unit 44 performs the same amount control simultaneously based on the selection information table, the power usage amount table, and the power generation amount table, and the power generation amount and the power consumer CD of the power generation devices 12 existing in the same region E. The power total amount adjustment parameter for each power generation device 12 is calculated based on the state of the power usage amount.

  The simultaneous equal amount control is a selection in which the total amount of power generated by the power generators 12 of the power producers CE1 to CEm and the total amount of power used by the power consumers CD1 to CDn are the same per predetermined period TA. The adjustment parameter calculation unit 44 predicts the total amount of power usage during the next predetermined period TA based on the current total amount of power usage during the predetermined period TA, and performs the same amount control simultaneously. Note that the total amount of power generation and the total amount of power usage do not have to be exactly the same, and the total amount of power generation may be greater than the total amount of power usage.

  The adjustment parameter calculation unit 44 sets one or more power generation devices 12 corresponding to the selection information as the power generation device 12 that supplies power according to the power usage of each power consumer CD in the same region E as the power consumer CD. Selection is made for each power consumer CD from among the plurality of power generation devices 12 so that the existing power generation devices 12 are given priority.

  The adjustment parameter calculation unit 44 assigns each power generator 12 to each power consumer CD with “minimum contract power generation amount” as a lower limit and “maximum contract power generation amount” as an upper limit. The difference between the “electric power generation amount” and the “maximum contract electric power generation amount” in the electric power generation amount table is the surplus electric energy, and the electric power generation amount corresponding to the extra electric energy increases the electric power consumption of the electric power consumer CD. Yes. The adjustment parameter calculation unit 44 may assign the maximum power generation amount to the power consumer CD with the maximum power generation amount as an upper limit for the power generation device 12 having a larger “maximum power generation amount” than the “maximum contract power generation amount”. it can. For the power generation amount exceeding the “maximum contract power generation amount”, a power rate higher than the normal rate is set.

  The adjustment parameter calculation unit 44 sets the “maximum power generation amount” exceeding the “maximum contract power generation amount”, for example, when simultaneous control of the same amount cannot be performed due to the presence of the power generation device 12 that cannot secure the “minimum contract power generation amount”. The power consumer CD can be assigned as the upper limit.

  Here, it is assumed that the selection information table is in the state shown in FIG. 4, the power usage amount table is in the state shown in FIG. 5, and the power generation amount table is in the state shown in FIG. In this case, for example, the adjustment parameter calculation unit 44 allocates the generated power of the power generation device 12 that performs solar power generation to the power consumer CD having the user ID “U101”.

  The power generation device 12 that performs solar power generation is, for example, the power generation devices 12 with the power generation device IDs “E101”, “E106”, and “E108”, and among these power generation devices 12, the power consumer CD with the user ID “U101” The power generated by one or more power generators 12 existing in the same region E is preferentially assigned to the power consumer CD having the user ID “U101”.

  The power generation device 12 with the power generation device ID “E101” exists in the region “EA”, and the power generation devices 12 with the power generation device IDs “E106” and “E108” exist in the region “EB”. Further, the electric power consumer CD of the user ID “U101” exists in the area “EA”. Therefore, the adjustment parameter calculation unit 44 preferentially assigns the power generation device 12 with the power generation device ID “E101” to the power consumer CD with the user ID “U101”. When the power generation amount of the power generation device 12 with the power generation device ID “E101” is all assigned to another power consumer CD, the adjustment parameter calculation unit 44 generates the power generation devices 12 with the power generation device IDs “E106” and “E108”. Among them, the power consumer CD having the user ID “U101” is allocated to the power generation device 12 having a sufficient power generation amount.

  Further, for example, the adjustment parameter calculation unit 44 allocates the power generation amount of the power generation apparatus 12 that performs solar power generation, wind power generation, and hydropower generation (non-pumping) to the power consumer CD having the user ID “U102”. . The adjustment parameter calculation unit 44, for example, has the same region “EA” as the power consumer CD of the user ID “U102” among the power generation devices 12 of the power generation device IDs “E101” to “E103”, “E106” and “E108” Are assigned to the power consumer CD of the user ID “U102” with priority given to the power generation amount of the power generation devices 12 of the power generation devices ID “E101” to “E103”. The adjustment parameter calculation unit 44 assigns the power generation device 12 with the power generation device IDs “E101” to “E103” with a lower power generation fee to the power consumer CD with the user ID “U102” with priority. Can do.

  In addition, for example, the adjustment parameter calculation unit 44, for the power consumer CD of the user ID “U103”, the power generation amount of the power generation device 12 that generates natural energy and the power of the power generation device 12 that performs thermal power generation. The power generation amount is 50% of the power generation amount, and the power generation amount of the power generation device 12 existing in the same region “EB” as the power consumer CD of the user ID “U103” is preferentially assigned. Examples of the natural power generation include solar power generation, wind power generation, and hydropower generation (non-pumped water). Thermal power generation is, for example, thermal power generation (natural gas), thermal power generation (oil), and thermal power generation (coal).

  Further, for example, the adjustment parameter calculation unit 44 assigns the generated power to the power consumer CD having the user ID “U104” with priority from the lowest generated power generation fee based on the power generation amount table. For example, the adjustment parameter calculation unit 44 prioritizes the power generated by the power generation device 12 of the power generation device ID “E105” that exists in the same region “EB” as the power consumer CD of the user ID “U104” and has the lowest power generation fee. And assign. In addition, the adjustment parameter calculation unit 44 considers the extra charge added for each of the coupling devices 8a and 8b, and preferentially assigns the power generator 12 that does not require the extra charge to the power consumer CD.

  As described above, the adjustment parameter calculation unit 44 refers to the selection information table, the power usage amount table, and the power generation amount table so that the total amount of power usage and the total amount of power generation amount become the same amount at the same time as a whole. Based on the state of the power generation amount and the power usage amount for each type of the power generation device 12 selected by the power consumer CD and for each region E, the power generation device 12 and the power generation amount are allocated to the power consumer CD.

  The adjustment parameter calculation unit 44 calculates a power total amount adjustment parameter for adjusting the power generation amount for each power generation device 12 for each predetermined period TA based on the information on the power generation device 12 and the power generation amount thus allocated. The total power adjustment parameter is information for designating the amount of power generated in the next predetermined period TA.

  In addition, when each electric power consumer CD does not specify the type of the power generation device 12, the adjustment parameter calculation unit 44 is based on the state of the power generation amount and the power usage amount for each region E regardless of the type of the power generation device 12. The total power adjustment parameter for each power generator 12 can be calculated.

  In addition, the adjustment parameter calculation unit 44 assigns the power generation device 12 and the power generation amount to each power consumer CD and calculates the total power adjustment parameter for each predetermined period TA. Therefore, the power consumer CD transmits selection information from the smart meter 11 in units of TA for a predetermined period to the power retail management apparatus 2, thereby generating a type of generated power that meets the demand of the power consumer CD in units of TA for a predetermined period. Can be provided.

  In addition, when the power generation device 12 of a type corresponding to the selection information cannot be selected for some of the power consumers CD, the adjustment parameter calculation unit 44 selects the power generation device 12 that is not of the type corresponding to the selection information as a part of the power. By assigning to the consumer CD, the same amount control is performed with priority.

The usage amount information acquisition unit 42 acquires information on the amount of power supplied from the plurality of power generation devices 12 respectively possessed by the plurality of power generators CE to the power transmission and distribution network 4 as information on the amount of power generation. The power generation amount information acquisition unit 43 acquires information on the amount of power supplied from the power transmission and distribution network 4 to each of the plurality of power consumers CD as information on the amount of power used. The adjustment parameter calculation unit 44 sets a power total amount adjustment parameter for making the electric power generation amount and the electric power consumption the same amount as a whole as a whole. Based on the state of usage, it is calculated for each power generation device 12. The adjustment parameter transmission unit 45 transmits the total power amount adjustment parameter to the power generation device 12.
