[0021] The consumer installation system 10 is a system used by an electric power consumer. FIG. 2 is a diagram showing an example of the configuration of the consumer installation system 10.

[0027] The power conditioning systems 13 may be disconnectably connected to the internal power grid 18. The number of power conditioning systems 13 connected to the internal power grid 18 may be changed by disconnecting the internal power grid 18 from one or more power conditioning systems 13.

[0028] The number of charging devices 15 connected to internal power system 18 is not limited to a specific number. One charging device 15 may be connected to internal power system 18, or multiple charging devices 15 may be connected to internal power system 18. Alternatively, no charging devices 15 may be connected to internal power system 18.

[0029] The charging devices 15 may be disconnectably connected to the internal power system 18. The number of charging devices 15 connected to the internal power system 18 may be changed by disconnecting one or more charging devices 15 from the internal power system 18.

[0030] The number of power sources 17 connected to internal power system 18 is not limited to a specific number.

[0031] The power sources 17 may be disconnectably connected to the internal power system 18. The number of power sources 17 connected to the internal power system 18 may be changed by disconnecting one or more power sources 17 from the internal power system 18.

[0032] The following description will be given taking as an example a case where the consumer installed system 10 includes one or more power loads 11, one or more power storage systems 12, one or more charging devices 15, one or more electric vehicles 16, and one or more power sources 17. The power loads 11, the power storage systems 12, the power conditioning systems 13, the storage batteries 14, the charging devices 15, the electric vehicles 16, and the power sources 17 are also collectively referred to as power facilities.

[0033] The type of customer installation system 10 is not limited to a specific type. For example, the power system 1 may include a customer installation system 10 configured as a factory and a customer installation system 10 configured as a private residence. The configuration of the customer installation system 10 may differ from one customer installation system 10 to another. In particular, the type and number of power facilities included in the customer installation system 10 may differ from one customer installation system 10 to another.

[0034] The internal power system 18 is a power system that exchanges power with each of the power facilities within the customer installed system 10. The internal power system 18 is also connected to the commercial power system 910 or the microgrid 20, and receives input of power from the commercial power system 910 or the microgrid 20. In the case of a contract that allows reverse power flow, the internal power system 18 may output power to the commercial power system 910 or the microgrid 20.

[0035] The power loads 11 are devices that consume power. As described above, the number of power loads 11 included in the customer installation system 10 is not limited to a specific number. Furthermore, the types of power loads 11 included in the customer installation system 10 are not limited to a specific type. The customer installation system 10 may include multiple power loads 11 of different types.

[0036] The storage battery 14 stores (charges) and discharges electricity. The power conditioning system 13 converts the charging and discharging power of the storage battery 14 between DC and AC. The power conditioning system 13 converts the charging power from the internal power system 18 to the storage battery 14 from AC to DC. The power conditioning system 13 also converts the discharging power from the storage battery 14 to the internal power system 18 from DC to AC.

[0037] The power conditioning system 13 also controls the charging and discharging of the storage battery 14. Specifically, the power conditioning system 13 causes a current to flow from the power conditioning system 13 to the storage battery 14, thereby charging the storage battery 14. The power conditioning system 13 also causes a current to flow from the storage battery 14 to the power conditioning system 13, thereby discharging the storage battery 14.

[0038] The power storage system 12 may be configured as a single device. Specifically, the power conditioning system 13 and the storage battery 14 may be configured integrally. Furthermore, one power storage system 12 may include a plurality of storage batteries 14 and a single power conditioning system 13 shared by the plurality of storage batteries 14.

[0039] The electric vehicle 16 is equipped with a storage battery and a motor and runs on electric power. The charging device 15 is installed so that it can be connected to and disconnected from the electric vehicle 16. When the electric vehicle 16 is connected, the charging device 15 controls the charging of the storage battery 14 of the electric vehicle 16. When charging the storage battery 14 of the electric vehicle 16, the charging device 15 converts AC power from the internal power system 18 into DC power, and allows DC current to flow from the charging device 15 to the storage battery 14 of the electric vehicle 16.

[0040] The charging device 15 may control discharging in addition to controlling charging of the storage battery 14 of the electric vehicle 16. When discharging the storage battery 14 of the electric vehicle 16, the charging device 15 causes a direct current to flow from the storage battery 14 of the electric vehicle 16 to the charging device 15. The charging device 15 then converts the direct current power from the storage battery 14 of the electric vehicle 16 into alternating current power and outputs it to the internal power system 18. The following describes an example in which the charging device 15 controls charging and discharging of the storage battery 14 of the electric vehicle 16. Charging and discharging of the storage battery 14 of the electric vehicle 16 is also referred to as charging and discharging of the electric vehicle 16.

[0041] The power source 17 is a device that supplies power. As described above, the number of power sources 17 included in the customer installation system 10 is not limited to a specific number. Furthermore, the type of power source 17 included in the customer installation system 10 is not limited to a specific type. For example, the power source 17 may be a solar cell. Furthermore, the power source 17 may be a generator. The customer installation system 10 may be provided with a plurality of power sources 17 of different types.

[0042] The power conditioning system 13, the charging device 15, and the control device 100 may each be treated as the power load 11. When the power source 17 consumes power, the power source 17 may be treated as the power load 11 with respect to power consumption.

[0043] The control device 100 generates an operation plan for a planning object and controls the planning object according to the generated operation plan. In particular, the control device 100 generates a plan for the input and output of power to the planning object. The control device 100 then controls the planning object so that the planning object inputs and outputs power according to the generated plan. The planning object can be considered as a control object. The control device 100 is an example of a planning device. The control device 100 is configured using, for example, a computer.

[0044] 1 , the control device 100 can be configured to plan the microgrid system 2. In this case, the control device 100 may generate an operation plan for the microgrid 20 and the customer installed system 10 connected to the microgrid 20.

[0045] For example, the control device 100 may generate a plan for the input and output of power between the microgrid 20 and the commercial power system 910. Then, the control device 100 may generate a plan for the input and output of power between the consumer installation system 10 and the microgrid 20 for each consumer installation system 10 so that the generated plan can be realized. Then, the control device 100 may transmit the plan generated for each consumer installation system 10 to the control device 100 of the consumer installation system 10, and cause the plan to be executed.

[0046] 2 (controller 100 of consumer installed system 10), the control device 100 can target the planning of the power equipment of consumer installed system 10. Specifically, the control device 100 can target the planning of power load 11, power storage system 12, electric vehicle 16, power source 17, or some of these.

[0047] For example, the control device 100 may generate a plan for the input and output of power between the power load 11, the power storage system 12, the electric vehicle 16, and the power source 17. The control device 100 may then control the power load 11, the power storage system 12, the electric vehicle 16, and the power source 17 so as to execute the generated plan.

[0048] In controlling the power storage system 12, the control device 100 transmits instructions to the power conditioning system 13 to charge and discharge the storage battery 14. In controlling the electric vehicle 16, the control device 100 transmits instructions to the charging device 15 to charge and discharge the electric vehicle. The control device 100 may be configured by combining multiple devices, such as by providing a control device 100 for each power facility.

[0049] Fig. 3 is a diagram showing an example of the configuration of the control device 100. In the configuration shown in Fig. 3, the control device 100 includes a communication unit 110, a storage unit 180, and a processing unit 190. The processing unit 190 includes a degradation characteristic information acquisition unit 191, a planning unit 192, and a control unit 193.

[0050] The communication unit 110 communicates with other devices. In particular, the communication unit 110 receives information used for planning, such as status information of the planning target, from the other devices. The communication unit 110 also transmits control commands to the planning target.

[0051] The storage unit 180 stores various types of data. For example, the storage unit 180 stores information used for planning, such as status information of the planning target received by the communication unit 110. The storage unit 180 is configured using a storage device included in the control device 100.

[0052] The processing unit 190 executes various processes by controlling each unit of the control device 100. The functions of the processing unit 190 are executed, for example, by a CPU (Central Processing Unit) included in the control device 100 reading out a program from the storage unit 180 and executing it.

[0053] The deterioration characteristic information acquisition unit 191 acquires deterioration characteristic information. The deterioration characteristic information is information that indicates the deterioration characteristics of the planning target, such as the storage battery 14. The deterioration characteristic information acquisition unit 191 corresponds to an example of a deterioration characteristic information acquisition means. The storage unit 180 may store the deterioration characteristic information, and the deterioration characteristic information acquisition unit 191 may read out the deterioration characteristic information from the storage unit 180. Alternatively, the planning target may store the deterioration characteristic information, and the deterioration characteristic information acquisition unit 191 may receive the deterioration characteristic information from the planning target via the communication unit 110.

[0054] The planner 192 generates an operation plan for the planning object. The planner 192 is an example of a planning means. Specifically, the planner 192 sets conditions related to the operation of the planning object, such as the specifications of the planning object, the state of the planning object, and plans already scheduled for the operation of the planning object, as constraints in an optimization problem. The planner 192 also sets an evaluation function that indicates an evaluation of the operation of the planning object relative to a goal, using the input and output of power in the planning object as arguments. The planner 192 then solves the optimization problem to search for a solution that improves the evaluation indicated by the evaluation function under the set constraints. The planner 192 adopts the input and output of power of the planning object obtained as a solution to the optimization problem as an operation plan for the planning object.

[0055] The planning unit 192 may generate an operation plan that indicates average input / output power or average input / output power amount for each time interval, such as 30 minutes, over a period from a certain point in time, such as 24 hours from the time of planning. The planning unit 192 may use watts (W) or kilowatts (kW) as the unit of power. The planning unit 192 may use watt-hours (Wh) or kilowatt-hours (kWh) as the unit of power amount.

[0056] The evaluation function set by the planning unit 192 can be various evaluation functions depending on the goal of the operation of the planning target. For example, the planning unit 192 may set an evaluation function that indicates a better evaluation the smaller (cheaper) the commercial electricity price is over the entire target period of the plan, but is not limited to this.

[0057] The planning unit 192 may generate constraint conditions or objective functions for an optimization problem using the following information: device specification information, service-related information, power supply and demand information, device status information, operating condition information, and device degradation characteristic information, or some of these. Note that in the following, the descriptions in brackets [ ] indicate examples of units.

[0058] (Device Specification Information) The planning unit 192 may use the following information or some of the information listed above as device specification information. Upper limit [kW] of charging power of the storage battery 14 Upper limit [kW] of discharging power of the storage battery 14 Upper limit [kWh] of the remaining amount of power stored in the storage battery 14 Lower limit [kWh] of the remaining amount of power stored in the storage battery 14 Charging efficiency (AC / DC conversion efficiency) of the power conditioning system 13 Discharging efficiency (DC / AC conversion efficiency) of the power conditioning system 13 Type of the power conditioning system 13 if it is a power conditioning system (such as a distinction between a hybrid PCS or a separate PCS)

[0059] (Service-Related Information) The planning unit 192 may use the following information or some of the information as the service-related information: Whether or not reverse power flow from the consumer installed system 10 to the commercial power grid 910 is permitted (for example, when there is a possibility of reverse power flow, such as when the consumer installed system 10 provides adjustment power to the commercial power grid 910) The mode of the energy management service (peak cut, peak shift, self-consumption, or the like) The peak cut threshold [kW] when the consumer installed system 10 performs peak cut The power selling price [yen / kWh] when the consumer installed system 10 sells power to the commercial power grid 910 The commercial power purchasing price by time period [yen / kWh]

[0060] The planning unit 192 may generate an operation plan using the actual value, current value, and planned value of the service-related information, or some of these values. The planned value of the service-related information may be accompanied by information indicating whether it can be changed.

[0061] (Power supply and demand information) The planner 192 may use the following information or some of the information as the power supply and demand information: A cumulative value [kWh] of the demand load power amount for each customer installed system 10 or device A cumulative value [kWh] of the generated power amount of the power source 17

[0062] The power supply and demand information may include information indicating the amount of input and output power for each device or system, or may include information indicating the amount of input and output power for the consumer installed system 10. The planner 192 may generate an operation plan using actual values, current values, and planned values ​​of the power supply and demand information, or some of these values. Information indicating whether the planned values ​​of the power supply and demand information can be changed may be added to the planned values.

[0063] (Device Status Information) The planner 192 may use the following information as device status information: Current value [kWh] or SOC [%] of the remaining power of the storage battery 14

[0064] (Operational Condition Information) The planner 192 may use the following information or some of the information listed above as the operational condition information: Parallel-off operation plan (plan for whether the planned target is to be connected to or disconnected from the power grid) Planned value of self-consumption amount (amount of reduction in electrical energy stored in the device or system due to its own consumption) [kWh] Planned value of supplementary charging amount (amount of power generated within the device or system, or amount of power supplied from sources other than the power system 1) [kWh]

[0065] The self-consumption amount in the operating condition information may include the amount of energy reduction due to self-discharge of the device or system, the amount of energy reduction due to deterioration of the device or system, or both. The operating condition information may be accompanied by information indicating whether it is changeable. If the operating condition information is changeable, the planner 192 may use the conditions indicated by the operating condition information as initial values ​​in the optimization problem.

[0066] (Deterioration characteristic information of storage battery 14) The planner 192 may use the following information or some of the information as the deterioration characteristic information of the storage battery 14: Information indicating deterioration characteristics of the storage battery 14 that depend on charge / discharge power Information indicating deterioration characteristics of the storage battery 14 that depend on the imbalance in the amount of charge / discharge power Information indicating deterioration characteristics of the storage battery 14 that depend on the remaining amount of power stored

[0067] As described above, the planner 192 may generate an operation plan using part of this information. Furthermore, the information used by the planner 192 to generate the operation plan is not limited to this. For example, the planner 192 may generate an operation plan using information indicating the deterioration characteristics of devices other than the storage battery 14, such as the deterioration characteristics of a solar cell, in addition to or instead of the information indicating the deterioration characteristics of the storage battery 14.

[0068] By generating an operation plan using the operating condition information for the period covered by the plan, the planning unit 192 is expected to be able to generate an operation plan for a device or system that has unique operating constraints, such as an electric vehicle 16, a heat pump water heater, or a microgrid system 2.

[0069] For example, the planner 192 may use the following operational condition information for the electric vehicle 16: Parallel-off operation plan: whether the electric vehicle is connected to a charger / discharger; Self-consumption amount: the amount of decrease in the storage capacity due to the running of the electric vehicle; Supplementary charging amount: the amount of increase in the storage capacity due to charging the electric vehicle away from home.

[0070] Furthermore, if the power load 11 is a heat pump water heater, the planning unit 192 may use the following operational condition information: Self-consumption: Amount of reduction in hot water storage capacity (converted into power amount) due to hot water supply by the water heater Whether reverse power flow is possible: Reverse power flow is not possible (power is not output from the heat pump water heater)

[0071] Furthermore, the planner 192 may use the following operating conditions for the microgrid system 2. Parallel-off operation plan: whether the microgrid 20 is connected to the commercial power grid 910 (whether the microgrid 20 is disconnected from the grid); Self-consumption amount: the amount of decrease in the amount of power due to consumption within the microgrid system 2; Supplementary charging amount: the amount of increase in the amount of power due to power generation within the microgrid system 2.

[0072] Furthermore, by having the planning unit 192 generate an operation plan using information indicating the deterioration characteristics of the storage battery 14, it is expected that it will be possible to generate a longer-term operation plan, such as a 20-year operation plan, with relatively high accuracy.

[0073] The planner 192 may set the constraint condition shown in Equation (1) as one of the constraint conditions using the information on the parallel-off operation plan.

[0074]

[0075] Here, t denotes a time interval. ｔ indicates the parallel-off operation plan in time interval t. ｔ = 0, and D indicates that the inverter is not disconnected (in parallel). ｔ = 1. In the case of a parallel-off operation plan for an individual device, the device being disconnected from the internal power grid 18 corresponds to being parallel-off, and the device being connected to the internal power grid 18 corresponds to not being parallel-off. However, the method of expressing the parallel-off operation plan is not limited to a specific one.

[0076] P ｔ indicates the input / output power in the time interval t that is the target of the parallel-off plan. ｔ For example, in the case of input power, P ｔ ≧0, and in the case of output power P ｔ ≦0. Alternatively, in the case of input power, P ｔ ≦0, and in the case of output power P ｔ ≧0.

[0077] Here, "x" indicates multiplication. ｍａｘ is the input / output power P ｔ indicates the upper limit of P ｍｉｎ is the input / output power P ｔ This indicates the lower limit of P ｍａｘ and the value of P ｍｉｎ The value of may be determined in advance according to the specifications of the target of the parallel-off plan.

[0078] When the planning target is a device or system that has a storage battery 14 and does not discharge, such as an electric vehicle 16 that does not discharge or a microgrid system 2 that does not perform reverse power flow, the planning unit 192 may set the constraint condition shown in equation (2) as one of the constraint conditions using the operational condition information.

[0079]
