DETAILED DESCRIPTION OF THE INVENTION

[0011] 1 is a schematic diagram of an information processing system S according to this embodiment. The information processing system S includes an information processing device 1, a generator 2, and a storage battery 3 that can communicate with each other via a network NW. The network NW includes, for example, a mobile communication network, a fixed communication network, or the Internet.

However, the respective numbers of information processing devices 1, generators 2, and storage batteries 3 are not limited to this. For example, the processing executed by the information processing device 1 of this embodiment may be executed by a plurality of information processing devices 1 that are distributed.

[0013] An overview of the processing executed by the information processing device 1 of this embodiment will be described. The operation of the control unit 11 of the information processing device 1 includes: when detecting an error between predicted and actual power supply and demand, determining whether the error indicates a power shortage; when determining that the error indicates a power shortage, determining which of a first method of generating power using the generator 2 and a second method of purchasing power from an external source and discharging it from the storage battery 3 has a lower power procurement cost or carbon dioxide emissions; and when determining that the error indicates a power surplus, determining which of a third method of reducing the amount of power generated by the generator 2 and a fourth method of charging the surplus power to the storage battery 3 to reduce the amount of purchased power has a lower power procurement cost or carbon dioxide emissions; and procuring power using the method with the lower power procurement cost or carbon dioxide emissions. With this configuration, even if an error occurs between predicted and actual power supply and demand, the information processing device 1 can achieve simultaneous equalization by compensating using both the generator 2 and the storage battery 3. Furthermore, the information processing device 1 can reduce power procurement costs or carbon dioxide emissions.

[0014] The information processing device 1 is a device that controls a generator 2 and a storage battery 3. In this example, the information processing device 1 is a power conditioner. The information processing device 1 supplies power to one or more consumers.

[0015] In FIG. 2, the internal configuration of the information processing device 1 will be described in detail.

[0016] The information processing device 1 includes a control unit 11, a communication unit 12, and a storage unit 13. The components of the information processing device 1 are connected to each other via, for example, a dedicated line so that they can communicate with each other.

[0017] The control unit 11 includes, for example, one or more general-purpose processors including a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The control unit 11 may include one or more dedicated processors specialized for specific processing. Instead of including a processor, the control unit 11 may include one or more dedicated circuits.

[0020] The generator 2 is a power device that generates electrical energy. In this case, the generator 2 is a fuel cell. Alternatively, the generator 2 may be any device capable of generating electricity.

[0021] The storage battery 3 is a battery that can be used repeatedly by being charged. The storage battery 3 may be called a secondary battery or a rechargeable battery.

[0022] Hereinafter, the information processing method performed by the information processing device 1 will be described in detail with reference to FIGS.

[0023] In step S1, the control unit 11 of the information processing device 1 detects an error between the prediction and the actual result of the power supply and demand. The prediction and the actual result data are acquired by the control unit 11 and stored in the storage unit 13.

[0024] In step S2, the control unit 11 determines whether the error indicates a power shortage.

[0025] If the answer is Yes in step S2, the control unit 11 determines in step S3 which of the following has a lower power procurement cost or carbon dioxide emissions: a first method of generating power using the generator 2, or a second method of purchasing power from an external source (for example, a grid) and discharging it from the storage battery 3. It is possible to arbitrarily set whether to compare the power procurement cost or the carbon dioxide emissions between the first method and the second method.

[0026] The method for calculating the power procurement cost or the carbon dioxide emission amount is arbitrary. For example, the calculation of the carbon dioxide emission amount may be performed by the following method. (1) When generating electricity The control unit 11 calculates the amount of carbon dioxide emitted per kWh from the amount of carbon dioxide emitted when the fuel in the fuel cell is burned and the power generation efficiency, and multiplies this by the amount of power generation. (2) When purchasing electricity For example, the following website publishes the amount of carbon dioxide emissions per kWh of purchased electricity for each electricity supplier. The control unit 11 multiplies the published amount of emissions by the amount of electricity purchased. https: / / ghg-santeikohyo.env.go.jp / files / calc / r05_coefficient.pdf (3) When selling electricity The control unit 11 subtracts the value obtained by multiplying the amount of carbon dioxide emissions per kWh in the case of power generation by the amount of electricity sold.

[0027] If the control unit 11 determines that the second method has a lower power procurement cost or a lower carbon dioxide emission amount, it sets the battery priority mode in step S4. The name of the mode can be set arbitrarily.

[0028] In step S5, the control unit 11 determines whether the error between the prediction and the actual result (hereinafter also simply referred to as "error") is equal to or less than the amount of stored power in the storage battery 3.

[0029] If the answer is Yes in step S5, the control unit 11 discharges the storage battery 3 to compensate for the error in step S6. Specifically, the control unit 11 discharges the storage battery 3 so as to compensate for the error.

[0030] If the answer is No in step S5 (ie, if the error exceeds the amount of stored electricity), the control unit 11 determines whether the error is equal to or less than the sum of the amount of stored electricity and the power generation reserve of the generator 2 in step S7.

[0031] If the answer is Yes in step S7, the control unit 11 performs full discharge of the storage battery 3 and power generation by the generator 2 in step S8 to compensate for the error.

[0032] If the answer is No in step S7, in step S9, the control unit 11 performs the following to address the error: power generation of the entire power generation surplus capacity of the generator 2 and full discharge of the storage battery 3. In this case, since the entire error cannot be filled, the remaining error is not addressed.

[0033] If the control unit 11 determines in step S3 that the power procurement cost or carbon dioxide emission amount of the first method is lower, the control unit 11 sets the generator priority mode in step S10.

[0034] In step S11, the control unit 11 determines whether the error is equal to or less than the power generation reserve of the generator 2.

[0035] If the answer is Yes in step S11, the control unit 11 controls the generator 2 to generate power in response to the error in step S12, thereby compensating for the error.

[0036] If the determination in step S11 is No, the control unit 11 determines in step S13 whether the error is equal to or smaller than the sum of the amount of stored electricity in the storage battery 3 and the power generation reserve of the generator 2.

[0037] If the answer is Yes in step S13, the control unit 11 executes in step S14 power generation of the entire power generation surplus capacity of the generator 2 and discharge of the storage battery 3 in response to the error.

[0038] If the answer is No in step S13, in step S15, the control unit 11 performs the following to address the error: power generation of the entire remaining power generation capacity of the generator 2; and discharge of the entire remaining charge capacity of the storage battery 3. The remaining error that has not been filled is abandoned.

[0039] If the answer is No in step S2 (i.e., there is surplus electricity), the control unit 11 determines in step S21 which of the following methods has a lower electricity procurement cost or carbon dioxide emissions: the third method of reducing the amount of electricity generated by the generator 2, or the fourth method of charging the surplus electricity to the storage battery 3 to reduce the amount of electricity purchased.

[0040] If the control unit 11 determines in step S21 that the power procurement cost or carbon dioxide emission amount of the fourth method is lower, the control unit 11 sets the generator priority mode in step S22.

[0041] In step S23, the control unit 11 determines whether the error is equal to or smaller than the reduction margin of the amount of power generated by the generator 2.

[0042] If the answer is Yes in step S23, the control unit 11 reduces the amount of power generated by the generator 2 in response to the error, thereby compensating for the error.

[0043] If the answer is No in step S23, the control unit 11 determines in step S25 whether the error is equal to or smaller than the sum of the reduction margin of the power generation amount of the generator 2 and the charging margin of the storage battery 3.

[0044] If the determination in step S25 is Yes, the control unit 11 reduces the total amount of available power reduction of the generator 2 and charges the storage battery 3 in response to the error in step S26.

[0045] If the answer is No in step S25, in step S27, the control unit 11 reduces the entire amount of the reduction reserve capacity of the generator 2 and charges the entire amount of the charge reserve capacity of the storage battery 3 in response to the error. If the error cannot be filled, the control unit 11 gives up on dealing with it.

[0046] In step S21, it is determined that the third method has a lower power procurement cost or a lower carbon dioxide emission amount, and the control unit 11 sets the battery priority mode in step S28.

[0047] In step S29, the control unit 11 determines whether the error is equal to or less than the remaining charge capacity of the storage battery 3.

[0048] If the answer is Yes in step S29, the control unit 11 causes the storage battery 3 to be charged in step S30.

[0049] If the determination in step S29 is No, the control unit 11 determines in step S31 whether the error is equal to or smaller than the sum of the reduction margin for the amount of power generated by the generator 2 and the charging margin for the storage battery 3.

[0050] If the determination in step S31 is Yes, the control unit 11 reduces the entire reduction margin of the power generation amount of the generator 2 and charges the storage battery 3 in response to the error in step S32.

[0051] If the answer is No in step S31, in step S33, the control unit 11 reduces the entire amount of power generation reserve of the generator 2 and charges the entire amount of charge reserve of the storage battery 3 to compensate for the error. If the error cannot be compensated for, the control unit 11 gives up on dealing with it.

[0052] As described above, according to this embodiment, the operation of the control unit 11 of the information processing device 1 includes: when detecting an error between the predicted and actual power supply and demand, determining whether the error indicates a power shortage; when determining that the error indicates a power shortage, determining which of the following methods has a lower power procurement cost or carbon dioxide emissions: a first method of generating power using the generator 2 or a second method of purchasing power from an external source and discharging it from the storage battery 3; and procuring power using the method with the lower power procurement cost or carbon dioxide emissions: when determining that the error indicates a power surplus, determining which of the following methods has a lower power procurement cost or carbon dioxide emissions: a third method of reducing the amount of power generated by the generator 2 or a fourth method of charging the surplus power to the storage battery 3 to reduce the amount of purchased power; and procuring power using the method with the lower power procurement cost or carbon dioxide emissions. With this configuration, even if an error occurs between the predicted and actual power supply and demand, the information processing device 1 can achieve simultaneous equalization by compensating using both the generator 2 and the storage battery 3. Furthermore, the information processing device 1 can reduce power procurement costs or carbon dioxide emissions.

With this configuration, the information processing device 1 can compensate for the error and achieve simultaneous equalization.

[0055] Furthermore, according to this embodiment, the operation of the control unit 11 includes, when it is determined that the power procurement cost of the fourth method is lower, comparing the error with the reduction margin of the power generation of the generator 2, and, when it is determined that the error is equal to or less than the reduction margin, reducing the power generation of the generator 2 in response to the error. The operation of the control unit 11 includes, when it is determined that the error exceeds the reduction margin, comparing the error with the sum of the reduction margin of the power generation of the generator 2 and the charging margin of the storage battery 3, and, when it is determined that the error is equal to or less than the sum, reducing the entire reduction margin of the power generation of the generator 2 and charging the storage battery 3 in response to the error.
