Description

[Technical field]

[0001] The present invention relates to a management fee calculation device and a management fee calculation method for calculating a fee for providing a power management service. [Background technology]

[0002] It has been proposed to provide a service that controls the charging and discharging of storage batteries used by consumers (see, for example, Patent Document 1). When calculating the remuneration to be received in consideration for providing such a service, a fixed amount of remuneration can be calculated as a usage fee for the storage battery, or the remuneration can be calculated according to the amount of electricity used by the consumer (see, for example, Patent Document 2).

[0003] However, due to the liberalization of electricity, the value obtained by discharging from and charging to storage batteries has become more diverse, making it difficult to calculate the remuneration. For this reason, it is no longer appropriate to calculate the remuneration as a uniform flat rate or pay-as-you-go system. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-137368 A [Patent Document 2] JP 2013-169067 A Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a technology that calculates a fee for the provision of a power management service that manages the electricity used by a consumer, which fee is satisfactory to both the consumer and the power management service provider. [Means for solving the problem]

[0006] To solve the above problems, the present invention provides: A management fee calculation device that calculates a fee for a power management service provided by a power management service provider that manages power used by a consumer, comprising: a profit information acquisition unit that acquires information regarding an economic profit obtained by implementing the power management service; a value index acquisition unit that acquires a value index indicating a value realized for the consumer by the power management service; a difficulty level index acquiring unit that acquires a difficulty level index indicating a difficulty level related to implementation of the power management service; a price calculation unit that calculates a price for the power management service by apportioning the economic benefit acquired by the profit information acquisition unit to the consumer and the power management service provider based on the value index and the difficulty index; The present invention is characterized by comprising:

[0007] According to this, the compensation for the power management service is calculated by apportioning the economic benefits obtained from the implementation of the power management service to the consumer and the power management service provider based on a value index that indicates the value realized for the consumer by the implementation of the power management service and a difficulty index that indicates the difficulty of implementing the power management service, so that a compensation that is satisfactory to both the consumer and the power management service provider can be calculated.

[0008] In the present invention, a calculation criterion table in which the value index and the difficulty index for each type of power management service are associated with each other; a type-based benefit recording unit that records the type of the implemented power management service and the economic benefit in association with each other; Equipped with The benefit information acquisition unit acquires the economic benefit for the type of the implemented power management service from the type benefit recording unit; the value index acquisition unit and the difficulty level index acquisition unit acquire the value index and the difficulty level index for the type of the implemented power management service from the calculation criterion table; The compensation calculation unit may calculate the compensation for the power management service by apportioning the economic benefit for each type of power management service implemented between the consumer and the power management service provider based on the value index and the difficulty index for that type.

[0009] According to this, by providing a calculation standard table which associates a value index and difficulty index for each type of power management service, and a type benefit recording section which records the type of power management service implemented in association with the economic benefit, it is possible to calculate a compensation which is satisfactory to both the consumer and the management service provider depending on the type of power management service implemented.

[0010] In the present invention, The calculation criterion table may be changeable.

[0011] According to this, if the value for the consumer that should be realized through the implementation of the power management service changes due to a change in the content of the contract between the consumer and the management service provider, if the difficulty of implementing the power management service changes due to changes in the system or market conditions, or if the content of the power management service changes, it is possible to change the value index and difficulty index for the power management service for each type of power management service set in the calculation standard table, thereby making it possible to calculate a price that is satisfactory to both the consumer and the power management service provider.

[0012] In the present invention, the value realized at the consumer is value obtained by controlling the power used at the consumer, The degree of difficulty may be a degree of difficulty in controlling the power used in the consumer so as to obtain the value.

[0013] According to this, the compensation is calculated by apportioning it between the consumer and the power management service provider based on a value index that indicates the value that can be obtained by controlling the power used by the consumer, and a difficulty index that indicates the difficulty of controlling the power used by the consumer so as to obtain this value, so that a compensation that is satisfactory to both the consumer and the management service provider can be calculated.

[0014] In the present invention, The control of the electric power used in the consumer may be performed by controlling at least one of a load, an energy storage device that stores input electric energy, and a power generation device used by the consumer.

When an electricity management service provider provides an electricity management service that satisfies the above requirements, the provider can calculate a price that is satisfactory to both the consumer and the management service provider. Here, the energy storage device is not limited to a device that stores input electrical energy in the form of electrical energy, such as a storage battery, but may be a device that operates a heat pump using input electrical energy and stores the energy in the form of thermal energy by boiling hot water using the heat pump, and the energy storage device is not limited to these. Also, the power generation device may be a solar power generation device or a fuel cell, and the power generation type is not limited to these.

[0016] In the present invention, The fee calculation unit may calculate the fee for the power management service by apportioning the economic benefit and costs related to the equipment used by the consumer between the consumer and the power management service provider based on the value index and the difficulty index.

[0017] According to this, the price for the power management service is calculated by apportioning the costs related to the equipment used by the consumer between the consumer and the power management service provider, in addition to the economic benefits obtained from the implementation of the power management service. Therefore, even in cases where the power management service provider bears the costs required for the installation and maintenance of the equipment used by the consumer to provide the power management service, these costs are also apportioned between the consumer and the power management service provider, making it possible to calculate a price that is more satisfactory to both the consumer and the power management service provider.

[0018] The present invention also provides a method for producing a semiconductor device comprising the steps of: A method for calculating a fee for a power management service provided by a power management service provider that manages power used by a consumer, comprising: obtaining information regarding economic benefits obtained by implementing the power management service; obtaining a value index indicating a value realized for the consumer by the power management service; obtaining a difficulty index indicating a difficulty of implementing the power management service; calculating a price for the power management service by apportioning the economic benefit between the consumer and the power management service provider based on the value index and the difficulty index; The present invention is characterized by comprising:

[0019] According to this, the compensation for the power management service is calculated by apportioning the economic benefits obtained from the implementation of the power management service to the consumer and the power management service provider based on a value index that indicates the value realized for the consumer by the implementation of the power management service and a difficulty index that indicates the difficulty of implementing the power management service, so that a compensation that is satisfactory to both the consumer and the power management service provider can be calculated.

[0022] [Application example] Hereinafter, application examples of the present invention will be described with reference to the drawings. FIG. 1 shows a power management system 100 to which the present invention is applied.

[0023] In the power management system 100, a management service provider provides a service for controlling the charging and discharging of a storage battery 105 to a consumer 104 that receives power from a commercial power system 101, thereby realizing various values.

[0024] The compensation for the provision of the management service is calculated according to the contents of the service menu that realizes various values. Specifically, the actual profit obtained by the battery control unit 109 is recorded in the electricity usage record database 110 in association with the service menu. In addition, the apportionment determination table 111 registers, for each service menu, a customer value index (hereinafter also simply referred to as "value index") that is an index for evaluating the value realized by the consumer through the service menu, and a difficulty index that evaluates the difficulty level when the service provider implements the charge / discharge control corresponding to the service menu.

[0025] The management fee calculation unit 1 obtains the actual profit of the implemented service menu from the electricity usage record database 110, and obtains the value index and difficulty index of the service menu from the apportionment determination table 111. Then, the actual profit obtained by the implemented service menu is apportioned to the customer and the service provider based on the value index and difficulty index of the service menu, thereby calculating the consideration for the provision of the management service (service consideration). Here, the management fee calculation unit 1 corresponds to the management fee calculation device of the present invention.

[0026] The service price calculation method will be described with reference to the flowchart shown in FIG. First, the storage battery control unit 109 performs charge / discharge control of the storage battery 105 (step S1). Figure 6 shows an example of the service menu implemented on a certain day (target day). The service menu implemented here includes peak shifting, adjustment power market, and imbalance avoidance.

[0027] Next, the profit information acquisition unit 11 of the management fee calculation unit 1 acquires the actual profit amount for the implemented service menu from the electricity usage record database 110 (step S2). FIG. 4(B) shows an example of data in the electricity usage record database 110 in which the actual profit obtained by the charge / discharge control implemented on the above-mentioned target date is recorded for each service menu. Here, the actual profit of peak shift is 1,000 yen, the actual profit of the adjustment power market is 100 yen, the actual profit of imbalance avoidance is 1,000 yen, and the actual profit of the adjustment power market is 1,000 yen. The profit is 600 yen. Here, the profit information acquisition unit 11 corresponds to the profit information acquisition unit of the present invention.

[0028] Next, the value index acquisition unit 12 of the management fee calculation unit 1 acquires the value index and difficulty index of the implemented service menu from the apportionment determination table 111 (steps S3 and S4). Fig. 3(B) shows an example of the data configuration of the apportionment determination table 111. Here, the value index and difficulty index of the peak shift are 50 and 50, respectively, the value index and difficulty index of the adjustment power market are 10 and 90, respectively, and the value index and difficulty index of imbalance avoidance are 20 and 80, respectively. Here, the value index acquisition unit 12 and the difficulty index acquisition unit 13 correspond to the value index acquisition unit and difficulty index acquisition unit of the present invention, respectively.

[0029] Next, the calculation unit 14 of the management fee calculation unit 1 calculates the service fee by apportioning the actual profit acquired in step S2 between the service provider and the consumer based on the value index and the difficulty index acquired in steps S3 and S4. Here, a total of 1,160 yen is allocated to the service provider for peak shifting: 1000×(50 / (50+50))=500 yen, for the adjustment power market: 100×(90 / (10+90))+100×(90 / (10+90))=180 yen, and for imbalance avoidance: 600×(80 / (20+80))=480 yen. On the other hand, the consumers are allocated 1000×(50 / (50+50))=500 yen for the peak shift, 100×(10 / (10+90))+100×(10 / (10+90))=20 yen for the adjustment power market, and 600×(20 / (20+80))=120 yen for imbalance avoidance, totaling 640 yen. Of this, 1,160 yen allocated to the service provider is calculated as the service fee. Here, the service fee is calculated by allocating the actual profit obtained by the implemented service menu in accordance with the ratio between the value index and the difficulty index. The method of calculating the service fee by allocating the actual profit to the customer and the service provider based on the value index and the difficulty index is not limited to this. Here, the calculation unit 14 corresponds to the fee calculation unit of the present invention.

[0030] In this way, according to the present invention, it is possible to provide a technology that calculates a remuneration that is acceptable to both the consumer and the service provider in consideration for the provision of a service that controls the storage battery 105, which is a service that manages the electricity used by the consumer.

[0031] Example 1 (Power Management System) In the following, a power management system 100 including a management fee calculation unit 1 according to a first embodiment of the present invention will be described in more detail with reference to the drawings. The following description of the embodiment merely exemplifies the present invention, and the present invention is not limited to the specific form described below. The present invention can be modified in various ways within the scope of its technical concept.

[0032] 1 shows a schematic configuration of an energy management system 100 including a management fee calculation unit 1 according to a first embodiment of the present invention. The energy management system 100 includes at least the management fee calculation unit 1, a storage battery 105, a storage battery power conditioner 106, a charge / discharge measurement unit 107, a system measurement unit 108, a storage battery control unit 109, an electricity usage record database 110, and an apportionment determination table 111.

[0033] In the power management system 100 , a load 103 that consumes power supplied through a power line 102 connected to a commercial power system 101 is provided at a consumer 104 .

[0034] The storage battery 105 is charged with power supplied from the commercial power system 101 through the power line 102, and supplies discharged power to the load 103 or the commercial power system 101. Between the storage battery 105 and the power line 102, a converter is provided to convert AC power supplied from the power line 102 into DC power. A storage battery power conditioner (power conditioner) 106 is connected to the storage battery 105, which converts the DC power discharged from the storage battery 105 into AC power, and a charge / discharge measurement unit 107 is connected between the storage battery power conditioner 106 and the power line 102, which measures the power charged to the storage battery 105 and the power discharged from the storage battery 105. The storage battery 105 corresponds to the electric energy storage device of the present invention that stores input electric energy in the form of electric energy.

[0035] A system measurement unit 108 is provided between the commercial power system 101 and the load 103, which measures the power supplied from the commercial power system 101 through the power line 102 or the power supplied to the commercial power system 101. Although omitted in Fig. 1, the AC power supplied from the commercial power system 101 is supplied to the load 103 and the storage battery 105 via a distribution board, and the power discharged from the storage battery 105 is supplied to the load 103 and the commercial power system 101 via the distribution board.

[0036] A battery control unit 109 that controls charging and discharging of the storage battery 105 is communicatively connected to the storage battery 105. The battery control unit 109 may be, for example, an EMS (Energy Management System) provided in the consumer 104, or may be a device that controls the storage battery 105 and the like through the EMS. The power management service control unit 121 may be provided in the consumer 104, or may be installed in an office or the like of a management service provider and connected to the EMS via a network.

[0037] The power measured by the charge / discharge measurement unit 107 and the power measured by the grid measurement unit 108 are transmitted to and recorded in an electricity usage history database 110. In addition, information on the type of management menu that has been implemented is transmitted from the storage battery control unit 109 to the electricity usage history database 110 as information on control over the storage battery 105, and the information is recorded therein.

[0038] The electricity usage record database 110 is connected to the management fee calculation unit 1. In addition, the management fee calculation unit 1 is connected to an apportionment determination table 111. The electricity usage record database 110 corresponds to the type-based benefit recording unit of the present invention.

[0039] (Management Fee Calculation Department) In the power management system 100, the charging and discharging of the storage battery 105 is controlled, thereby making it possible to manage the power used by the consumer 104. Various values ​​are known as values ​​that electricity has, such as the value of the amount of electricity (kWh value), the value of capacity (supply capacity) (kW value), the value of adjustment capacity (ΔkW value), environmental value, BCP value, etc., and these values ​​are becoming increasingly diversified. By controlling the charging and discharging of the storage battery 105, various values ​​can also be realized at the consumer 104. In the power management system 100 of this embodiment, the management service provider provides a service of controlling the charging and discharging of the storage battery 105 as a power management service, based on a request from the consumer 104, in order to realize various values ​​of power.

[0040] Here, the storage battery 105 is owned or managed by a management service provider, and charges and discharges the storage battery 105 for the consumer 104. The consumer 104 may own the storage battery 105, and the management service provider may provide a service for controlling the charging and discharging of the storage battery.

[0041] The charge / discharge control services provided by the management service provider include a plurality of types of charge / discharge control services according to the value to be realized. Here, BCP refers to maintaining the remaining charge of the storage battery 105 above a certain value in order to maintain daily life and business activities by supplying the power discharged from the storage battery 105 to the load 103 when the supply of power from the commercial power system 101 is stopped due to a breakdown or accident in the commercial power system 101 or due to a disaster. Peak shifting refers to supplying the power discharged from the storage battery 105 to the load 103 during periods of high power demand. The day-night shift is a shift from daytime to nighttime consumption of power supplied from the commercial power system 101 by charging the storage battery 105 at nighttime when electricity rates are low, discharging the power stored in the storage battery 105 during the daytime when electricity rates are high, and charging the storage battery 105 with power supplied from the commercial power system 101 during a time period when load power demand is low. The adjustment power market is a market in which adjustment power for matching demand and supply in response to fluctuations in demand and supply is traded. By changing the power consumed by the load 103 of the consumer 104 from the power supplied from the commercial power system 101 to the power discharged from the storage battery 105, it is possible to adjust the demand in a direction to decrease, and this can be traded as adjustment power. It is also possible to adjust the demand in a direction to increase by charging the storage battery 105 with the power supplied from the commercial power system 101. Imbalance avoidance is a market in which the difference between demand and supply is adjusted in 30-minute increments when a difference between a planned value and an actual value occurs. As for avoiding imbalance, the demand can be adjusted to decrease by changing the power consumed by the load 103 of the consumer 104 from the power supplied from the commercial power grid 101 to the power discharged from the storage battery 105, and this can be traded to avoid imbalance. In addition, the demand can be adjusted to increase by charging the storage battery 105 with the power supplied from the commercial power grid 101. Self-consignment is a service provided by a general electric utility when a person who owns a power generation facility transmits electricity to another business establishment, etc. of the person who owns the power generation facility via the transmission and distribution network maintained and operated by the general electric utility, and other-party consignment is a service provided by a general electric utility when transmitting electricity to a business establishment, etc. of a person other than the person who owns the power generation facility. Environmental value is the reduction in carbon dioxide emissions by a power generation facility that does not use fossil fuels, and the reduced carbon dioxide emissions can be traded bilaterally or in the market as emission rights.

[0042] By managing electricity, as described above, it is possible to realize and actualize the value of electricity. Here, various values ​​of electricity are realized by controlling the charging and discharging of the storage battery 105. Specifically, it is possible to generate real profits by implementing different types of charging and discharging control corresponding to the respective values ​​of electricity.

[0043] FIG. 2 is a functional block diagram of the management fee calculation unit 1. The management fee calculation unit 1 is composed of a general computer. That is, the management fee calculation unit 1 is a computer having a processor such as a CPU or GPU, a main storage device such as a RAM or ROM, an auxiliary storage device such as an EPROM, a hard disk drive, or a removable medium, and a communication interface for connecting to a network. The removable medium may be, for example, a USB memory or a disk recording medium such as a CD or DVD. The auxiliary storage device stores an operating system (OS), various programs, various tables, etc., and the programs stored therein are loaded into the working area of ​​the main storage device and executed, and each component is controlled through the execution of the programs, thereby realizing each function that matches a predetermined purpose, as described below. However, some or all of the functions may be realized by a hardware circuit such as an ASIC or an FPGA. The management fee calculation unit 1 may be composed of a single computer, or may be composed of multiple computers that cooperate with each other.

[0044] The management fee calculation unit 1 has a profit information acquisition unit 11, a value index acquisition unit 12, a difficulty index acquisition unit 13, and a calculation unit 14. Here, the management fee calculation unit 1 corresponds to the management fee calculation device of the present invention. The management fee calculation device of the present invention may include an electricity usage record database 110 and an apportionment determination table 111. The profit information acquisition unit 11 acquires the electricity usage record obtained by the charge / discharge control of the storage battery 105 from the electricity usage record database 110. As shown in FIG. 3, the electricity usage record database 110 includes a service menu, which is a type of management service provided by the management service provider. The menu of services provided by the customer and the amount of actual profit obtained by the management service are associated with each other and recorded as actual values ​​of electricity usage. There is no limitation on the method of associating such a management service menu with the actual profit and recording it in the electricity usage record database 110. For example, a fee table of a general electric utility that supplies power through the commercial power grid 101 may be provided, and the actual profit for the implemented service menu may be calculated based on this fee table and the amount of power consumption of the consumer 104 measured by the grid measurement unit 108. In addition, in the case of a market transaction, information on the actual profit may be obtained from a server of an institution that operates the market, and recorded in the electricity usage record database 110 in association with the implemented management service.

[0045] The value index acquisition unit 12 acquires a value index which is an index indicating the value realized by the management service for the consumer. As long as this value index is an index indicating the value realized by the management service for the consumer, the method of evaluating the value when indexing is not limited. The value index acquisition unit 12 corresponds to the value index acquisition unit of the present invention.

[0046] The difficulty index acquisition unit 13 acquires a difficulty index which is an index indicating the difficulty of implementing the management service. As long as the difficulty index is an index indicating the difficulty of implementing the management service, the method of evaluating the value when indexing is not limited. Furthermore, the difficulty of implementing the management service may be either technical difficulty or economic difficulty for ensuring profits, or may include both. The difficulty index acquisition unit 13 corresponds to the difficulty index acquisition unit of the present invention.

[0047] The calculation unit 14 acquires the actual profit, value index, and difficulty index from the profit information acquisition unit 11, value index acquisition unit 12, and difficulty index acquisition unit 13, respectively, depending on the type of management service provided, and calculates the consideration for the provision of the management service (service consideration) based on this information. The service consideration is calculated by apportioning the actual profit between the consumer and the service provider based on the value index and difficulty index. This apportionment between the consumer and the service provider is carried out ideally in order to calculate the service consideration. The calculation unit 14 corresponds to the consideration calculation unit of the present invention.

[0048] FIG. 3(A) shows an example of the data configuration of the apportionment decision table. In the apportionment decision table, for each service menu, a value index indicating the value realized by the management service for the consumer and a difficulty index indicating the difficulty of implementing the management service are registered. In the apportionment decision table, a value number is assigned as a number for identifying the service menu. For example, value number 1 corresponds to the BCP service menu, and C1 and D1 are registered as the value index and difficulty index for this service menu. Similarly, value number 2 corresponds to the peak shift service menu, and C2 and D2 are registered as the value index and difficulty index for this service menu. Value number 3 corresponds to the day / night shift service menu, and C3 and D3 are registered as the value index and difficulty index for this service menu. Value number 4 corresponds to the adjustment power market service menu, and C4 and D4 are registered as the value index and difficulty index for this service menu. Value number 5 corresponds to the service menu of self-consignment, and C5 and D5 are registered as the value index and difficulty index corresponding to this service menu. Value number 6 corresponds to the service menu of imbalance avoidance, and C6 and D6 are registered as the value index and difficulty index corresponding to this service menu. Value number 7 corresponds to the service menu of other company consignment, and C7 and D7 are registered as the value index and difficulty index corresponding to this service menu. Value number 8 corresponds to the service menu of environmental value (relative), i.e., a service in which environmental value is traded on a relative basis, and C8 and D8 are registered as the value index and difficulty index corresponding to this service menu. Value number 9 corresponds to the service menu of environmental value (market), and C10 and D11 are registered as the value index and difficulty index corresponding to this service menu. This corresponds to a service menu, i.e., a service for trading environmental value in the market, and C9 and D9 are registered as the value index and difficulty index corresponding to this service menu. Similarly, Cn and Dn are registered as the value index and difficulty index for the menu to which value number n is assigned. The service menu of the management service is not limited to this, and specific numerical values ​​are actually registered for the value index and difficulty index Ci and Di (1≦i≦n) shown here. The apportionment determination table 111 corresponds to the calculation standard table of the present invention.

[0049] FIG. 4(A) shows an example of an actual profit table recorded in the electricity usage record database 110. In the actual profit table, actual profits obtained by implementing the management service are registered for each service menu. In the actual profit table, a value number is assigned as a number for identifying the service menu. For example, Pr1 is registered as actual profit obtained by implementing the BCP service menu with value number 1. Similarly, Pr2 is registered as actual profit obtained by implementing the peak shift service menu with value number 2. Pr3 is registered as actual profit obtained by implementing the day / night shift service menu with value number 3. Pr4 is registered as actual profit obtained by implementing the adjustment power market service menu with value number 4. Pr5 is registered as actual profit obtained by implementing the self-consignment service menu with value number 5. Pr6 is registered as actual profit obtained by implementing the imbalance avoidance service menu with value number 6. Pr7 is registered as actual profit obtained by implementing the other company consignment service menu with value number 7. Pr8 is registered as the actual profit gained by implementing the service menu of environmental value (relative) with value number 8. Pr9 is registered as the actual profit gained by implementing the service menu of environmental value (market) with value number 9. Similarly, Prn is registered as the actual profit gained by implementing the service menu assigned value number n. The service menu is not limited to this, and actual profit Pri (1≦i≦n) shown here is actually registered as a specific numerical value. The actual profit recorded in the actual profit table is calculated for an appropriate period (target period) such as one day, one week, one month, three months, six months, one year, etc., depending on the cycle or timing for calculating the service fee. In addition, since the same service menu may be implemented multiple times during the target period, the actual profit table may record the actual profit in association with the date and time when the management service was implemented. In such a case, the profit information acquisition unit 11 acquires information recorded as the actual profit for the period required to calculate the service fee from the actual profit table.

[0050] The calculation unit 14 calculates the compensation for the provision of the management service based on the actual profit, the value index, and the difficulty index registered in association with the value number corresponding to the provided management service. The calculation unit 14 calculates the compensation Fp(i) for the management service of the value number i (1≦i) using a coefficient fpi(Ci,Di) (where 0≦fpi(Ci,Di)≦1) expressed as a function of the value index Ci and the difficulty index Di, as follows: Fp(i) = Pri × fpi(Ci,Di) Here, the coefficient fpi(Ci,Di) is a coefficient for calculating the compensation for the provision of the management service by apportioning the profits obtained by the management service between the service provider and the consumer. Here, if Fc(i)=Pri×(1-fpi(Ci,Di)), 0≦1-fpi(Ci,Di)≦1, and Fp(i)+Fc(i)=Pri. That is, this Fc(i) represents the apportionment to the consumer when the profits obtained by the management service are apportioned between the service provider and the consumer. In this way, the coefficients fpi(Ci,Di) and 1-fpi(Ci,Di) are coefficients that respectively represent the apportionment to the service provider and the consumer when the profits obtained by the management service are apportioned between the service provider and the consumer.

[0051] (Service price calculation method) The above-mentioned service fee calculation method will be described with reference to the flowchart of Fig. 5. The service fee calculation method described below corresponds to the management fee calculation method of the present invention. This management fee calculation method is realized by loading a program stored in the auxiliary storage device of the management fee calculation unit 1 into the working area of ​​the main storage device and executing it by the processor, so it can also be configured as a program executed by a computer. First, a service provider performs charge / discharge control of the storage battery 105 as a power management service (step S1).

[0052] FIG. 6 shows a schematic diagram of the management service performed from 0:00 to 24:00 on a target day. This one day is divided into seven time slots Pd1 to Pd7 from the viewpoint of the management service. The three time slots Pd1, Pd5, and Pd7 are time slots without any particularly valuable menu, and the management service is not performed during these time slots. The time slot Pd2 is the time slot in which the value of peak shifting is the highest, and the management service of discharging the storage battery 105 for peak shifting is performed during this time slot. The time slots Pd3 and Pd4 are the time slots in which the value of the adjustment power market is the highest, and the management service of discharging the storage battery 105 to supply adjustment power traded through the adjustment power market is performed during these time slots. The time slot Pd6 is the time slot in which the value of imbalance avoidance is the highest, and the management service of discharging the storage battery 105 for imbalance avoidance is performed during this time slot. Here, the management service of discharging the storage battery 105 is described as an example, but the management service also includes control of obtaining actual profits by charging the storage battery 105.

[0053] When the management service is implemented in this way, the service menu, which is the content of the implemented management service, and the actual profit obtained by implementing the management service are associated and registered in the electricity usage record database 110. FIG. 4(B) is a diagram showing an example of the service menu and the amount of actual profit registered in the electricity usage record database 110 for the target day. Here, the actual profit of the peak shift with value number 2 is 1000 yen, the actual profit of the adjustment power market with value number 4 is 100 yen, and the actual profit of the imbalance avoidance with value number 6 is 600 yen. Note that on the target day, the management service corresponding to the adjustment power market of the service menu is implemented in the time slots Pd3 and Pd4, so in FIG. 4(B), these are distinguished by the branch number attached to the value number and the time slot in which the management service was implemented. The time slot Pd3 corresponds to 13:00 to 13:59 on July 1, 2020, and the time slot Pd4 corresponds to 14:00 to 15:59 on July 1, 2020.

[0054] The time period during which the management service was performed is obtained from the battery control unit 109 and registered in the electricity usage record database 110. When the same service menu is performed multiple times during a target period, a cumulative value obtained by adding up the actual profits over the target period may be registered, but as will be described later, even when the apportionment determination table 111 is allowed to be changed, it is preferable to be able to identify the actual profit for each implementation so that the service fee can be calculated in accordance with the applied apportionment determination table 111.

[0055] Next, the profit information acquisition unit 11 of the management fee calculation unit 1 acquires information on the service menu of the management services implemented during the target period and the actual profits obtained by implementing the management services from the electricity usage record database 110 (step S2). Here, the profit information acquisition unit 11 of the management fee calculation unit 1 acquires the service menu of the management services and the actual profits obtained by implementing these management services as shown in FIG. 4(B).

[0056] Next, the value index acquisition unit 12 and the difficulty index acquisition unit 13 of the management fee calculation unit 1 determine the apportionment The value index and the difficulty index of the implemented service menu are obtained from the table 111 (steps S3 and S4).

[0057] FIG. 3(B) shows a specific example of the apportionment decision table 111. In FIG. 3(B), since BCP is not included in the service menu that the management service provider should provide to the consumer, the values ​​of the value index and the difficulty index are omitted. For peak shifting with value number 2, the value index C2=50 and the difficulty index D2=50. For daytime / nighttime shifting with value number 3, the value index C3=70 and the difficulty index D3=70. For the adjustment power market with value number 4, the value index C4=10 and the difficulty index D4=90. For self-consignment with value number 5, the value index C5=30 and the difficulty index D5=70. For imbalance avoidance with value number 6, the value index C6=20 and the difficulty index D6=80. For other company consignment with value number 7, the value index C7=40 and the difficulty index D7=60.

[0058] As described above, the service menus of peak shifting, power adjustment market, and imbalance avoidance are implemented during the target period. Therefore, here, the value index acquiring unit 12 and the difficulty index acquiring unit 13 acquire the value index 50 and difficulty index 50 of peak shifting, the value index 10 and difficulty index 90 of the power adjustment market, and the value index 20 and difficulty index 80 of imbalance avoidance from the apportionment determination table 111.

[0059] Next, the calculation unit 14 of the management fee calculation unit 1 calculates the service fee (step S5).

[0060] As described above, peak shifting, the power adjustment market, and imbalance avoidance are implemented as management services during the target period. At this time, management services from the power adjustment market are provided twice. The actual profits obtained from peak shifting, the power adjustment market, and imbalance avoidance are 1,000 yen, 100 yen, and 600 yen, respectively. In addition, the value index and difficulty index of peak shifting are 50 and 50, respectively, the value index and difficulty index of the power adjustment market are 10 and 90, respectively, and the value index and difficulty index of imbalance avoidance are 20 and 80, respectively. In this case, the coefficient fpi(Ci,Di) is expressed as fpi(Ci,Di)=Di / (Ci+Di). Here, if the values ​​obtained by the value index acquisition unit 12 and the difficulty index acquisition unit 13 from the apportionment determination table 111 are substituted for C2, D2, C4, D4, C6, and D6, respectively, fp2(C2, D2) = 50 / 100, fp4(C4, D4) = 90 / 100, and fp6(C6, D6) = 80 / 100.

[0061] Using the above values, the service fee Fp is calculated as follows: Fp= Pr2×fp2(C2,D2)+Pr4×fp4(C4,D4)+Pr4×fp4(C4,D4)+Pr6×fp6(C6,D6)= 1000×(50 / 100)+100×(90 / 100)+100×(90 / 100)+600×(80 / 100)= 1,160 yen In this case, the allocation Fc of the actual profits obtained by the management service in the target period to the consumers is calculated as follows. Fc= Pr2×(1-fp2(C2,D2))+Pr4×(1-fp4(C4,D4))+Pr4×(1-fp4(C4,D4))+Pr6×(1-fp6(C6,D6))= 1000×(1-(50 / 100))+100×(1-(90 / 100))+100×(1-(90 / 100))+600×(1-(80 / 100))= 640 yen

[0062] As described above, the service fee calculation executed in the management fee calculation unit 1 according to the first embodiment According to this method, the actual profit, which is the economic benefit obtained by providing the charging and discharging service of the storage battery 105, is calculated by apportioning it between the consumer and the service provider based on the value index and the difficulty index, so that a service fee that is satisfactory to both the consumer and the service provider can be calculated.

[0063] In this one day, three types of management services are implemented, but the management services to be implemented are not limited to these. Also, although the management service has been described as controlling the storage battery 105 to discharge the stored power, the management service also includes control of charging the storage battery 105.

[0064] (Modification) In the first embodiment, the management fee calculation unit 1 obtains the actual profit for each service menu from the electricity usage record database 110, and divides this actual history between the service provider and the consumer to calculate the compensation for the provision of the management service. When the consumer purchases and manages the equipment including the storage battery 105 by himself, the calculation can be performed in the above-mentioned manner, but the management form of the equipment including the storage battery 105 is not limited to this. For example, the management service provider may install the equipment including the storage battery 105 owned by the management service provider for use by the consumer, and the management of the equipment may be performed by the management service provider. In such a case, the profit obtained by implementing the management service, which is the subject of the allocation when calculating the compensation for the provision of the management service, may include not only the actual profit, but also the initial cost required for installation and the operating cost required for maintenance and management divided according to the target period. Such initial cost and operating cost or the cost divided for the target period may be stored in the cost storage unit 15 provided in a predetermined area of ​​the auxiliary storage device included in the management fee calculation unit 1, as shown in FIG. 7. In addition, the profit information acquiring unit 11 may acquire these costs from a device that manages information on the initial cost, operating cost, and the like related to the storage battery 105.

[0065] In this way, according to the management fee calculation unit 1 in the modified example, even if the service provider bears the costs required for the installation and maintenance of the storage battery 105, these costs are also apportioned between the consumer and the service provider, making it possible to calculate a fee that is more satisfactory to both the consumer and the service provider.

[0066] Example 2 The following describes a power management system 200 including a management fee calculation unit 1 according to a second embodiment of the present invention. Fig. 8 shows a schematic configuration of the power management system 200. Configurations common to the first embodiment will be designated by common reference numerals and detailed descriptions thereof will be omitted. The power management system 200 includes at least a management fee calculation unit 1, a storage battery 105, a storage battery power conditioner 106, a charge / discharge measurement unit 107, a system measurement unit 108, a storage battery control unit 109, an electricity usage record database 110, an apportionment determination table 111, and an apportionment determination table management unit 112.

[0067] The power management system 200 includes an apportionment determination table management unit 112 that manages the apportionment determination table 111. The apportionment determination table management unit 112 manages the apportionment determination table 111 used to calculate the service fee, and updates the apportionment determination table 111 as necessary. As shown in FIG. 3, the apportionment determination table 111 records a service menu, a value index, and a difficulty level index in association with each other. The configuration of the service menu may change due to changes in the system related to power, changes in the configuration of the power management system 200, changes in the contents of the contract between the customer and the power management service provider, etc. In addition, the value of the value index may change due to changes in the contents of the contract between the customer and the power management service provider. In addition, the difficulty level index may change due to changes in the system related to power or the market situation related to power. In response to these cases, the apportionment determination table management unit 112 updates the apportionment determination table 111. Here, the management fee calculation device of the present invention includes a management fee calculation unit 1 and an apportionment determination table management unit 112, and may further include an electricity usage record database 110 and an apportionment determination table 111.

[0068] The apportionment determination table management unit 112 is configured by a general computer. That is, the apportionment determination table management unit 112 is a computer having a processor such as a CPU or GPU, a main storage device such as a RAM or ROM, an auxiliary storage device such as an EPROM, a hard disk drive, or a removable medium, an input device such as a keyboard or a mouse, and a communication interface for connecting to a network. The removable medium may be, for example, a USB memory or a disk recording medium such as a CD or DVD. The auxiliary storage device stores an operating system (OS), various programs, various tables, etc., and the programs stored therein are loaded into the working area of ​​the main storage device and executed, and each component part is controlled through the execution of the programs, thereby realizing each function that matches a predetermined purpose, as described later. However, some or all of the functions may be realized by a hardware circuit such as an ASIC or an FPGA. The apportionment determination table management unit 112 may be configured by a single computer, or may be configured by multiple computers that cooperate with each other. The apportionment determination table management unit 112 may also be configured by a computer common to the management fee calculation unit 1.

[0069] 9 shows a functional block diagram of the apportionment determination table management unit 112. The apportionment determination table management unit 112 includes an input unit 1121, an apportionment basic information acquisition unit 1122, and a table update unit 1123. The input unit 1121 is configured with an input device such as a keyboard, a mouse, or a touch panel display, and receives an instruction to change the value index or the difficulty level index. The apportionment basic information acquisition unit 1122 is configured including a communication interface, and when there is information (basic information) that is the basis for determining the value index or the difficulty level index, it acquires such basic information from an external server or the like. The table update unit 1123 changes the value index or the difficulty level index registered in the apportionment determination table 111 based on the change instruction received by the input unit 1121 or the basic information acquired by the apportionment basic information acquisition unit 1122. The table update unit 1123 may change the apportionment determination table 111 as needed in response to a change instruction received or a change to the basic information, or may change the table in accordance with the timing of calculation of the fee for providing the management service.

[0070] Fig. 10 is a flowchart for explaining a service fee calculation method including changes to the apportionment determination table 111. The same processes as those in Fig. 5 are designated by the same reference numerals and detailed explanations are omitted.

[0071] If the service menu, value index, and difficulty index are recorded in the apportionment decision table 111, steps S11 and S12 are omitted, and charge / discharge control of the storage battery 105 is performed as a management service (step S1). Then, the service fee is calculated (step S14). The service fee calculation process in step S14 includes steps S2 to S5 of the flowchart shown in FIG.

[0072] Next, if an instruction to change the apportionment determination table 111 is received via the input unit 1121, or if the apportionment basic information acquisition unit 1122 acquires a change in the basic information, i.e., if the table update unit 1123 judges Yes in step S15, the process proceeds to step S11, where a value index for each menu is set (step S11), a difficulty index for each menu is set (step S12), and the contents of the apportionment determination table 111 are changed. Then, the process proceeds to step S1, where charge / discharge control of the storage battery 105 is performed, and the service fee is calculated based on the updated apportionment determination table 111 (step S14).

[0073] If an instruction to change the apportionment determination table 111 via the input unit 1121 has not been accepted, and if the apportionment basic information acquisition unit 1122 has not acquired a change in the basic information, that is, If the table update unit 1123 determines No in step S15, the process proceeds to step S1, where charge / discharge control of the storage battery 105 is performed, and the service fee is calculated based on the same apportionment determination table 111 as before (step S14).

[0074] As described above, by making the apportionment determination table management unit 112 of Example 2 capable of changing the apportionment determination table 111, the managed fee calculation unit 1 can change the value index and difficulty index for each service menu set in the apportionment determination table 111 when the value of the consumer that should be realized by implementing the service menu changes due to a change in the contents of the contract between the consumer and the service provider, when the difficulty of implementing the service menu changes due to a change in the system or market conditions, or when the contents of the service menu change, and a fee that is satisfactory to both the consumer and the service provider can be calculated.

[0075] Example 3 In the following, a power management system 300 including a management fee calculation unit 1 according to a third embodiment of the present invention will be described. Fig. 11 shows a schematic configuration of the power management system 300 according to the third embodiment of the present invention.

[0080] The power management system 200 is provided with a power management service control unit 121 that controls the storage battery 105, the fuel cell 113, the solar cell 116, and the heat pump water heater 119. That is, the power management service control unit 121 controls the charging and discharging of the storage battery 105, the power generation of the fuel cell 113 and the solar cell 116, and the heating of hot water by the heat pump water heater 119. The power management service control unit 121 may be, for example, an EMS (Energy Management System) provided in the consumer 104, or may be a device that controls the storage battery 105, etc. through the EMS. Furthermore, the power management service control unit 121 may be provided in the consumer 104, or may be provided in an establishment or the like of a management service provider and connected to the EMS via a network.

[0081] Information relating to the control of the storage battery 105, fuel cell 113, solar cell 116, and heat pump water heater 119 from the power management service control unit 121, i.e., the contents of the menu of management services implemented by the management service provider by controlling the storage battery 105, etc., is stored in the electricity usage history database 110. In addition to the grid measurement unit 108 and charge / discharge measurement unit 107, a fuel cell power measurement unit 115, a solar cell power measurement unit 118, and a heat pump power measurement unit 120 are connected to the electricity usage history database 110, and the amount of power input and output in association with the management services implemented by the management service provider is recorded.
