Description

[Technical field]

[0001] The present invention relates to an information processing device, an information processing method, and a program. [Background technology]

[0002] Conventionally, self-dispatch is known as a mechanism for transmitting power output from a power generation facility to a demand facility via a power grid managed by a third-party entity (see Patent Document 1). In order to perform self-dispatch, it is required to match a power generation plan or demand plan formulated in advance with the power generation record or demand record in the actual supply in 30-minute increments. In a configuration that applies a power source that generates power using renewable energy, it is possible to balance the difference between the planned amount of power generated and the actual amount of power generated by using a power storage device provided in the power generation facility. In particular, in a configuration that uses a power source in which the predicted value of the generated power meets the expected power demand on average, a power storage device with a large storage capacity is required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of an information processing device to which the present disclosure is applied will be described with reference to the drawings.

[0013] As shown in Fig. 1, a power management system 11 including a first information processing device 10 of an embodiment may be configured to include the first information processing device 10, a second information processing device 12, a third information processing device 13, a fourth information processing device 14, and a network 15. In Fig. 1, the first information processing device 10, the second information processing device 12, the third information processing device 13, and the fourth information processing device 14 may communicate information via the network 15. The power management system 11 may manage information for operating a power supply and demand system 19 including a plurality of power sources 16, a plurality of power demand areas 17, and a power transmission and distribution network 18.

[0014] The first information processing device 10 is assumed to be used at least by a first business operator that is a self-transportation business operator. The first business operator may treat at least one first power source 20 and at least one first power demand area 21 as objects of management. The first business operator may have the first power source 20 as an asset. The first business operator may have the first power demand area 21 as an asset. The first business operator may treat the power demand area of ​​another business operator that belongs to the same association as the first power demand area 21 that is the object of management of the first business operator. The first business operator may also serve as a retail electricity business operator.

[0015] The at least one first power source 20 may include a plurality of first power sources 20. The first power source 20 is a power source 16 that generates power using renewable energy. The power source 16 may include a power storage device. The first power demand area 21 is a power demand area 17 to which power is supplied from the first power source 20 by self-dispatch.

[0016] The second information processing device 12 is assumed to be used by a second business operator that is a retail electricity business operator. The second business operator may purchase electricity from power generation business operators including at least the first business operator, and sell the electricity to consumers. The consumers may include the second business operator itself. The consumers may have a second electricity demand area 22. The second electricity demand area 22 is subject to management by the second business operator. In addition, the second electricity demand area 22 is an electricity demand area 17 to which electricity is supplied from various electricity sources 16 including the first electricity source 20 through sales from the retail electricity business operator.

[0017] The third information processing device 13 is assumed to be used by a third business operator that adjusts supply and demand in the electricity supply and demand system 19. For example, in Japan, the third business operator is OCCTO (Organization for Cross-regional Coordination of Transmission Operators).

[0018] The fourth information processing device 14 is assumed to be used by a fourth business entity that forecasts the weather in the area where the first power source 20 is installed.

[0019] In the electricity supply and demand system 19, when the first business uses the electricity transmission and distribution network 18 for self-dispatch, the first business is required to report to the third business the planned values ​​of the demand and supply of electricity through self-dispatch at a predetermined time interval (e.g., 30 minutes). The first business is also required to make the planned values ​​and actual values ​​at the predetermined time interval coincident. If a discrepancy between the planned values ​​and the actual values, that is, an imbalance occurs, a penalty (imbalance fee) is imposed according to the imbalance. In the following description, the planned value of the demand for electricity through self-dispatch is also referred to as the "first demand energy planned value." The planned value of the supply of electricity through self-dispatch is also referred to as the "first supply energy planned value."

[0020] Furthermore, in the electricity supply and demand system 19, when the second business operator uses the electricity transmission and distribution network 18 for retail sales, the second business operator is required to report to the third business operator planned values ​​of electricity demand and supply for retail sales in a predetermined time unit (e.g., 30 minutes). The second business operator is also required to match the planned values ​​and actual values ​​in a predetermined time interval. In the following explanation, the planned value of the electricity demand amount in the electricity demand area managed by the second business operator is also referred to as the "second demand energy planned value." The planned value of the supply amount of electricity to be supplied to the electricity demand area managed by the second business operator is also referred to as the "second supply energy planned value."

[0021] In the electricity supply and demand system 19 of the present embodiment, it is required that the actual value in the self-consignment business be brought closer to the planned value, and that the actual value in the retail business be brought closer to the planned value.

[0022] As shown in FIG. 2, the first information processing device 10 includes a communication unit 23 and a controller 24.

[0023] The communication unit 23 may include a communication module that communicates with the second information processing device 12, the third information processing device 13, and the fourth information processing device 14 via the network 15. The communication unit 23 may transmit and receive various information and commands. For example, the communication unit 23 may receive, as information, the amount of power generated for each different time period that is a predetermined time interval from the first power source 20 that is the management target of the first information processing device 10 used by the first business operator. Also, the communication unit 23 may receive, as information, the amount of power consumed for each time period from the first power demand area 21 that is the management target of the first information processing device 10 used by the first business operator. Also, the communication unit 23 may receive, as information, a predicted value of the amount of power to be purchased from a power generation business operator other than the first business operator.

[0024] The controller 24 includes one or more processors and memories. The processor may include a general-purpose processor that loads a specific program to execute a specific function, and a dedicated processor specialized for a specific process. The dedicated processor may include an application specific integrated circuit (ASIC). The processor may include a programmable logic device (PLD). The PLD may include a field-programmable gate array (FPGA). The controller 24 may be either a system-on-a-chip (SoC) or a system in a package (SiP) in which one or more processors work together.

[0025] The controller 24 calculates a first predicted value based on weather forecast information. The first predicted value is a predicted value of the amount of power generated by all the first power sources 20 that generate power from renewable energy and are managed by the first business operator, in other words, the first information processing device 10. The first power sources 20 that generate power from renewable energy are, for example, solar power sources and wind power sources. The weather forecast information is, for example, a predicted value of the amount of solar radiation and a predicted value of wind volume. The controller 24 calculates the first predicted value for the first power source 20 based on forecast information of the amount of solar radiation in the installation area of ​​the solar power generation first power source 20. The controller 24 calculates the first predicted value for the first power source 20 based on, for example, forecast information of the wind volume in the installation area of ​​the wind power generation first power source 20. The controller 24 may acquire weather forecast information from the fourth information processing device 14 via, for example, the communication unit 23.

[0026] The controller 24 calculates the second predicted value by subtracting the estimation error from the first predicted value. The estimation error is the difference between the lower limit of a prediction range estimated for the first predicted value and the first predicted value. The estimation error may be, for example, a value obtained by multiplying the first predicted value by a predetermined coefficient less than 1, such as 0.9. Alternatively, the estimation error may be, for example, the lower limit of a range of actual values ​​collected for the same past first predicted value. Therefore, the second predicted value is a predicted value of the amount of power that is likely to be secured.

[0027] The controller 24 calculates a third predicted value based on the environmental information of the first power demand area 21. The third predicted value is a predicted value of the amount of power used in the first power demand area 21. The environmental information is, for example, a temperature forecast value in the first power demand area 21 and an operation forecast of equipment in the first power demand area 21. The temperature forecast value improves the forecast accuracy of the amount of power for an air conditioner whose load varies depending on the temperature. The operation forecast improves the forecast accuracy of the amount of power for equipment such as a factory whose load varies depending on the operating status.

[0028] In a configuration in which a plurality of first power demand areas 21 are managed by the first information processing device 10, the third predicted value may be the sum of the predicted values ​​of the amount of power used in each of the plurality of first power demand areas 21.

[0029] The controller 24 calculates a fourth predicted value based on the third predicted value. The fourth predicted value is a predicted value of the amount of power to be supplied from the first power source 20 to the first power demand area 21. Specifically, the fourth predicted value is the amount of power in the first power demand area 21 that is required to supply the third predicted value to the first power demand area 21. The controller 24 may calculate the fourth predicted value by dividing the third predicted value by a value obtained by subtracting the transmission loss rate from 1. The transmission loss rate may be the transmission loss rate between the first power source 20 and the first power demand area 21.

[0030] In a configuration in which a plurality of first power demand areas 21 are managed by the first information processing device 10, the fourth predicted value may be a sum of predicted values ​​of the amount of power to be supplied from the first power source 20 to each of the plurality of first power demand areas 21. The predicted value of the amount of power to be supplied from the first power source 20 to each of the plurality of first power demand areas 21 may be based on a predicted value of the amount of power used in each of the plurality of first power demand areas 21.

[0031] The controller 24 determines whether the second predicted value exceeds the fourth predicted value for each of a plurality of time periods included in the unit time. The unit time is, for example, one day. The controller 24 calculates the first power supply amount plan value by accumulating the fourth predicted value in the time period in which the second predicted value exceeds the fourth predicted value by the unit time.

[0032] The controller 24 calculates a first demand energy plan value based on the first supply energy plan value. The first demand energy plan value is a predicted value of the amount of energy to be supplied to the first power demand area 21. The first demand energy plan value is the amount of energy corresponding to the first supply energy plan value and transmitted to the first power demand area 21. The controller 24 may calculate the first demand energy plan value by multiplying the first supply energy plan value by a value obtained by subtracting a transmission loss rate from 1.

[0033] The controller 24 controls the communication unit 23 to transmit the calculated first supply energy plan value and first demand energy plan value as information. The first supply energy plan value and the first demand energy plan value may be transmitted to the third information processing device 13 as planned values ​​from the first business entity that is a self-consignment business entity. The first supply energy plan value is a planned value of the amount of energy supplied from the first power source 20 to the power transmission and distribution network 18 as self-consignment. The first demand energy plan value is a planned value of the amount of energy supplied from the power transmission and distribution network 18 to the first power demand area 21 as self-consignment.

[0034] The controller 24 may control the communication unit 23 to transmit the first predicted value and the fourth predicted value to the second information processing device 12 as information.

[0035] The controller 24 may calculate a fifth predicted value obtained by subtracting the fourth predicted value from the first predicted value as a second supply energy plan value. The controller 24 may calculate a second demand energy plan value based on the second supply energy plan value. The second demand energy plan value may be a plan value of the amount of power supplied to at least one second power demand area 22 to which power is supplied from the first power source 20 that is the management target of the first information processing device 10. The second demand energy plan value is the amount of power transmitted to the second power demand area 22, which corresponds to the second supply energy plan value. The controller 24 may calculate the second demand energy plan value by multiplying the second supply energy plan value by a value obtained by subtracting the transmission loss rate from 1.

[0036] When the first utility company purchases electricity as a retail electricity supplier from a power generation supplier other than the first utility company, the controller 24 may calculate a second supply energy plan value and a second demand energy plan value by adding a predicted value of the amount of electricity to be purchased from the power generation supplier to the fifth predicted value.

[0037] The controller 24 may control the communication unit 23 to transmit the calculated second supply energy plan value and second demand energy plan value as information. The second supply energy plan value and the second demand energy plan value may be transmitted to the third information processing device 13 as planned values ​​from the first business entity, which is a retail electricity business entity. The second supply energy plan value is a planned value of the amount of energy to be supplied from the first power source 20 to the power transmission and distribution network 18 as retail sales. The second demand energy plan value is a planned value of the amount of energy to be supplied from the power transmission and distribution network 18 to the second power demand area 22 as retail sales.

[0038] The controller 24 may calculate a third actual value, which is the amount of power sold from the first utility as a self-wheeling utility to the first utility as a retail electricity utility, as described below. The controller 24 may acquire, as information, from the first power source 20, a first actual value, which is the amount of power actually generated by all the first power sources 20. The controller 24 may acquire, as information, from the first power demand area 21, the amount of power actually consumed by all the first power demand area 21. The controller 24 may calculate a second actual value by dividing the amount of power by a value obtained by subtracting the transmission loss rate between the first power source 20 and the first power demand area 21 from 1. The controller 24 may calculate the above-mentioned third actual value by subtracting the second actual value from the first actual value.

[0039] The controller 24 may associate environmental value information with the third actual result value. The controller 24 may control the communication unit 23 to transmit the environmental value information. The environmental value information is information indicating that the electricity is generated from renewable energy. The environmental value information includes both information issued in real time and information issued after a certain period of time, such as a non-fossil certificate. The controller 24 may transmit the environmental value information to a consumer who purchases electricity from the first business operator as a retail electricity business operator, for example.

[0040] As shown in FIG. 3, the second information processing device 12 includes a communication unit 25 and a controller .

[0041] The communication unit 25 may include a communication module that communicates with the first information processing device 10 and the third information processing device 13 via the network 15. The communication unit 25 may transmit and receive various information and commands. For example, the communication unit 25 receives the first predicted value and the fourth predicted value as information from the first information processing device 10. In addition, the communication unit 25 may receive a predicted value of the amount of power to be purchased from a power generation company other than the first company as information.

[0042] The controller 26 includes one or more processors and memories. The processor may include a general-purpose processor that loads a specific program to execute a specific function, and a dedicated processor specialized for a specific process. The dedicated processor may include an ASIC. The processor may include a PLD. The PLD may include an FPGA. The controller 24 may be either an SoC or a SiP in which one or more processors work together.

[0043] The controller 26 may calculate a fifth predicted value obtained by subtracting the fourth predicted value from the first predicted value as a second supply energy plan value. The controller 26 may calculate a second demand energy plan value based on the second supply energy plan value. The controller 26 may calculate the second demand energy plan value by multiplying the second supply energy plan value by a value obtained by subtracting the transmission loss rate from 1. When the second business operator purchases power from a power generation business operator other than the first business operator, the controller 26 may calculate the second supply energy plan value and the second demand energy plan value by adding a predicted value of the power amount of the power to be purchased from the power generation business operator to the fifth predicted value.

[0044] The controller 26 may control the communication unit 25 to transmit the calculated second supply energy plan value and second demand energy plan value as information. The second supply energy plan value and the second demand energy plan value may be transmitted to the third information processing device 13 as planned values ​​from the second business operator, which is a retail electricity business operator. The second supply energy plan value is a planned value of the amount of power supplied to the power transmission and distribution network 18 from the power sources 16 managed by the second business operator, including the first power source 20, as retail sales. The second demand energy plan value is a planned value of the amount of power supplied to the second power demand area 22 from the power transmission and distribution network 18 as retail sales.

[0045] Next, the first transmission process executed by the controller 24 of the first information processing device 10 in this embodiment will be described with reference to the flowchart in Fig. 4. The first transmission process is periodically started, for example, at an arbitrary time point before the time point set for submission to the third business operator.

[0046] In step S100, the controller 24 acquires weather forecast information for the area in which the first power source 20 is installed. The latest weather forecast information among the information acquired in advance from the fourth information processing device 14 may be used as the weather forecast information. Alternatively, the weather forecast information may be read from the fourth information processing device 14. After acquisition, the process proceeds to step S101.

[0047] In step S101, the controller 24 calculates a first predicted value based on the weather forecast information acquired in step S100. After the calculation, the process proceeds to step S102.

[0048] In step S102, the controller 24 calculates a second predicted value by subtracting the estimation error from the first predicted value calculated in step S101. After the calculation, the process proceeds to step S103.

[0049] In step S103, controller 24 acquires environmental information in first power demand area 21. After acquisition, the process proceeds to step S104.

[0050] In step S104, the controller 24 calculates a third predicted value based on the environmental information acquired in step S103. After the calculation, the process proceeds to step S105.

[0051] In step S105, the controller 24 calculates a fourth predicted value based on the third predicted value calculated in step S104 and the transmission loss rate between the first power source 20 and the first power demand area 21. After the calculation, the process proceeds to step S106.

[0052] In step S106, the controller 24 calculates a first power supply amount plan value based on the second predicted value calculated in step S102 and the fourth predicted value calculated in step S105. After the calculation, the process proceeds to step S107.

[0053] In step S107, the controller 24 calculates a first demand energy plan value based on the first supply energy plan value calculated in step S106 and the transmission loss rate between the first power source 20 and the first power demand area 21. After the calculation, the process proceeds to step S108.

[0054] In step S108, the controller 24 controls the communication unit 23 to transmit the first supply power amount plan value calculated in step S106 and the first demand power amount plan value calculated in step S107 to the third information processing device 13. After transmission, the process proceeds to step S109.

[0055] In step S109, the controller 24 determines whether or not the power generated by the first power source 20 is set to be sold to a retail electricity supplier. If it is set to be sold, the process proceeds to step S110. If it is not set to be sold, the process proceeds to step S111.

[0056] In step S110, the controller 24 controls the communication unit 23 to transmit, as information, the first predicted value calculated in step S101 and the fourth predicted value calculated in step S105 to the second information processing device 12. After the transmission, the first transmission process ends.

[0057] In step S111, the controller 24 determines whether the first business is set to be an electricity retailer. If the first business is set to be an electricity retailer, the process proceeds to step S112. If the first business is not set to be an electricity retailer, the first transmission process ends.

[0058] In step S112, the controller 24 calculates a second power supply amount plan value based on the first predicted value calculated in step S101 and the fourth predicted value calculated in step S105. After the calculation, the process proceeds to step S113.

[0059] In step S113, the controller 24 calculates a second demand power amount plan value based on the second supply power amount plan value calculated in step S112. After the calculation, the process proceeds to step S114.

[0060] In step S114, the controller 24 controls the communication unit 23 to transmit the second supply power amount plan value calculated in step S112 and the second demand power amount plan value calculated in step S113 to the third information processing device 13. After the transmission, the first transmission process ends.

[0061] Next, the second transmission process executed by the controller 24 of the first information processing device 10 in this embodiment will be described with reference to the flowchart of Fig. 5. The second transmission process starts, for example, after the date and time for which the first power supply plan value was created has passed.

[0062] In step S200, the controller 24 calculates a first performance value by summing up the amounts of power actually generated by the first power sources 20 for each predetermined time interval, which are acquired as information from all the managed first power sources 20. After the calculation, the process proceeds to step S201.

[0063] In step S201, the controller 24 sums up the amounts of power consumed in the first power demand areas 21 for each predetermined time interval, which are acquired as information from all the first power demand areas 21 that are subject to management. By summing up, the amount of power consumed at the date and time for which the first supply power amount plan value is created is calculated. After the calculation, the process proceeds to step S202.

[0064] In step S202, the controller 24 calculates a second actual value by dividing the amount of power calculated in step S201 by a value obtained by subtracting from 1 the transmission loss rate between the first power source 20 and the first power demand area 21. After the calculation, the process proceeds to step S203.

[0065] In step S203, the controller 24 calculates a third performance value by subtracting the second performance value calculated in step S203 from the first performance value calculated in step S200. After the calculation, the process proceeds to step S204.

[0066] In step S204, the controller 24 associates the environmental value information with the third result value calculated in step S203. After the association, the process proceeds to step S205.

[0067] In step S205, the controller 24 controls the communication unit 23 so as to transmit, to the consumer, the environmental value information associated with the third result value in step S205. After the transmission, the second transmission process ends.

[0068] Next, the third transmission process executed by the controller 26 of the second information processing device 12 in this embodiment will be described with reference to the flowchart of Fig. 6. The third transmission process starts after receiving the first predicted value and the fourth predicted value as information from the first information processing device 10, for example.

[0069] In step S300, the controller 26 calculates a second power supply amount plan value based on the received first predicted value and fourth predicted value. After the calculation, the process proceeds to step S301.

[0070] In step S301, the controller 26 calculates a second demand power amount plan value based on the second supply power amount plan value calculated in step S300. After the calculation, the process proceeds to step S302.

[0071] In step S302, the controller 26 controls the communication unit 25 to transmit the second supply power amount plan value calculated in step S300 and the second demand power amount plan value calculated in step S301 to the third information processing device 13. After the transmission, the third transmission process ends.

[0072] The first information processing device 10 configured as described above includes a controller 24 that calculates a first predicted value of the amount of power generated by all the first power sources 20 based on weather forecast information, calculates a second predicted value by subtracting an estimation error from the first predicted value, calculates a third predicted value of the amount of power used in at least one first power demand area 21 based on environmental information of the at least one first power demand area 21, calculates a fourth predicted value of the amount of power to be supplied to the at least one first power demand area 21 from all the first power sources 20 based on the third predicted value, calculates a first supply energy plan value by accumulating the fourth predicted values ​​in a time period in which the second predicted value exceeds the fourth predicted value among multiple time periods included in a unit time, and calculates the amount of power to be supplied to the first power demand area 21 based on the first supply energy plan value as a first demand energy plan value, and a communication unit 23 that transmits the first supply energy plan value and the first demand energy plan value as information. The prediction accuracy of the amount of power consumed in the power demand area 17 is higher than the prediction accuracy of the amount of power generated using renewable energy. Based on such a phenomenon, the first information processing device 10 calculates a planned value of the amount of power to be supplied to the power transmission and distribution network 18 (first supply power planned value) based on the planned value of the amount of power consumed in the power demand area 17 (first demand power planned value) rather than the amount of power generated by the power source 16. Therefore, the first information processing device 10 can calculate a planned value (first supply power planned value) that reduces the difference from the actual value. As a result, the first information processing device 10 can reduce the size or omit the capacity of the power storage device, thereby reducing the installation cost.

[0073] In order to increase the reliability of generating power of an amount equal to or greater than the first planned supply amount, a first power source 20 having a relatively large generating capacity compared to the expected demand is used. The remaining power, obtained by subtracting the power to be supplied to the first power demand area 21 from the power generated by the first power source 20, is sold to the retail electricity supplier, so that the first power source 20 owned by the first supplier can be effectively utilized. The retail electricity supplier generally receives power from a plurality of power sources 16 distributed over a wider range than the self-wheeling supplier. Therefore, the prediction of the power generated by the power sources 16 distributed over a wider range is generally averaged, so that the ratio of the difference between the planned value and the actual value to the actual value is relatively small. Therefore, the difference between the predicted value and the actual value of the power generated by the self-wheeling supplier can be absorbed by the predicted value and the actual value of the power generated by all the power sources managed by the retail electricity supplier.

[0074] Moreover, the first information processing device 10 calculates a fifth predicted value obtained by subtracting the fourth predicted value from the first predicted value as a second supply energy plan value, calculates a second demand energy plan value to be supplied to at least one second power demand area 22 to which power is supplied from the power source through sale based on the second supply energy plan value, and transmits the second supply energy plan value and the second demand energy plan value as information. With this configuration, the first information processing device 10 can transmit planned values ​​of the supply energy and demand energy as an electricity retailer (the second supply energy plan value and the second demand energy plan value).

[0075] Moreover, the first information processing device 10 associates environmental value information with a third actual value obtained by subtracting a second actual value obtained by dividing the amount of power actually consumed by at least one first power demand area 21 by a value obtained by subtracting the transmission loss rate between the first power source 20 and the first power demand area 21 from 1 from a first actual value of the amount of power actually generated by all first power sources 20, and transmits the environmental value information. With this configuration, the first information processing device 10 can add environmental value information as added value to the power sold to consumers by the first business operator as a retail electricity business operator.

[0076] The non-fossil fuel certificate included in the environmental value information is issued based on the actual value (amount of received power) of the meter for each power plant. In a plurality of power plants each belonging to a retail generation balancing group and a self-dispatch generation balancing group, it is preferable to allocate each power plant to the retail generation balancing group and the self-dispatch generation balancing group. This is because it is easy to certify the amount of received power of the power plant. The reason why the certification is easy is explained below. A meter of a general electricity transmission and distribution company installed only one at one power plant (power generation location) can measure the total amount of generated power (also called the amount of received power). As described above, in a configuration in which a plurality of power plants belong to the retail and self-dispatch generation balancing groups, the amount of retail power is measured by allocating any power plant to self-dispatch and another power plant to retail, so that the certification of the non-fossil fuel certificate becomes easy. This is because in the current system in Japan, the value measured by the meter at the power plant is certified as a non-fossil fuel certificate. The control for allocating retail or self-consignment for each power plant may be performed by the first information processing device 10 in FIG.

[0077] However, if any one business has only one power plant, it is not possible to separate the amount of received power into a retail power generation balancing group and a self-consignment power generation balancing group. This is because only one meter is installed, and therefore only the amount of generated power (received power) of the single power plant can be measured, and as a result, it is not possible to physically separate and measure the amount of self-consignment and retail.

[0078] As a method of dividing the above-mentioned events, the calculated value of the retail portion based on the power generation plan value divided into self-consignment and retail and the notified value of partial supply is used as the target of environmental value information. Even if it takes a certain period of time for the amount of electricity to be certified and become a non-fossil fuel certificate, it is possible to associate in real time and instantly estimate the environmental value of the retail portion calculated by the present invention.

[0079] Moreover, in the first information processing device 10, at least one first power demand area 21 includes a plurality of first power demand areas 21, the third predicted value is a sum of predicted values ​​of the amount of power used in each of the plurality of first power demand areas 21, and the fourth predicted value is a sum of predicted values ​​of the amount of power to be supplied from the first power source 20 to each of the plurality of first power demand areas 21 based on the predicted value of the amount of power used in each of the plurality of first power demand areas 21. With this configuration, the first information processing device 10 can transmit a first supply energy plan value and a first demand energy plan value for self-dispatch to the plurality of power demand areas 17.

[0080] The second information processing device 12 configured as above includes a communication unit 25 that receives the first predicted value and the fourth predicted value as information from the first information processing device 10, and a controller 26 that calculates a fifth predicted value obtained by subtracting the fourth predicted value from the first predicted value as a second supply energy plan value, calculates a second demand energy plan value to be supplied to at least one second power demand area 22 based on the second supply energy plan value, and transmits the second supply energy plan value and the second demand energy plan value as information to the communication unit 25. With such a configuration, the second information processing device 12 can transmit the plan values ​​of the supply energy and the demand energy as a retail electricity supplier (the second supply energy plan value and the second demand energy plan value).
