Description

[Technical field]

[0001] The present invention relates to an energy resource control method, a control device, and a program. [Background technology]

[0002] In recent years, issues with the conventional large-scale, centralized energy systems have become apparent, and as the introduction of renewable energy continues to expand, there has been a shift to distributed energy systems that utilize relatively small-scale energy resources that are dispersed over a region. Energy resources introduced on the consumer side, such as cogeneration systems such as solar power generation or household fuel cells, storage batteries, electric vehicles, and negawatts (saved electricity), are becoming more widespread.

[0003] Although each of these energy resources owned by homes or factories is small, a mechanism and concept known as a "virtual power plant (VPP)" has been proposed, in which these can be bundled (aggregated) using advanced energy management technology that utilizes the Internet of Things (IoT) and remotely and centrally controlled to adjust the balance of electricity supply and demand and function as if it were a single power plant.

[0004] In an energy control system using such a VPP mechanism, an aggregator is provided that performs integrated control of consumer energy resources, distributed energy resources, etc. The aggregator transmits power commands to operate the consumer's energy resources under control conditions according to the power service in which the consumer participates, thereby operating the energy resources under desired control conditions.

[0005] Patent Document 1 discloses a technique for transmitting a restoration operation message (state restoration command) to a consumer's target energy resource when the operation under such desired control conditions is to be terminated. As a result, the energy resource that receives the restoration operation message can terminate the control under the desired control conditions and operate under, for example, the operating conditions before the desired control conditions.

[0014] (How the present invention was arrived at) Prior to describing the present invention, the background to the invention will be described with reference to Fig. 1. Fig. 1 is a diagram showing an overview of an energy control system 1001 according to a comparative example. Fig. 1 is a diagram showing an overview of a virtual power plant (VPP). Note that a VPP is a system that comprehensively controls power generation facilities and energy resources scattered on a power grid or below a power receiving point, and controls them as if they were a single power plant (virtual power plant).

[0015] As shown in FIG. 1, the energy control system 1001 includes a community, a resource aggregator, and an aggregation coordinator. The number of communities, resource aggregators, and aggregation coordinators included in the energy control system 1001 is not limited to the number shown in FIG. 1. The resource aggregator and the aggregation coordinator may be collectively referred to as a power aggregator or an aggregator. Hereinafter, the resource aggregator and the aggregation coordinator are also collectively referred to as an aggregator. The aggregation coordinator may be collectively referred to as a power aggregator or an aggregator. The power aggregator or aggregator corresponds to a provisional specified wholesale supplier or a specified wholesale supplier.

[0016] Each community is composed of a plurality of consumers. FIG. 1 shows an example in which three communities composed of consumers A1 to A3, consumers B1 to B3, and consumers C1 to C3 are formed. One community is composed of, for example, one or more consumers managed by a resource aggregator. Resource aggregator A manages the power supply and demand of consumers A1 to A3, resource aggregator B manages the power supply and demand of consumers B1 to B3, and resource aggregator C manages the power supply and demand of consumers C1 to C3. Each of resource aggregators A to C manages the power supply and demand of one or more consumers different from each other. The number of consumers constituting a community is not limited to three. Moreover, consumers in a community do not need to be geographically close to each other.

[0017] At least one of the multiple consumers may have energy resources such as a solar cell (power generation facility), a storage battery (battery facility), or an electric water heater (hot water storage facility) using heat pump technology such as EcoCute (registered trademark).

[0018] Resource aggregators and aggregation coordinators are businesses that integrate and control consumer-side energy resources, distributed energy resources, etc., and provide energy services from virtual power plants (VPPs).

[0019] The resource aggregator is provided in each community, for example, and controls power for a plurality of consumers in the community. Various types of information are transmitted and received between the resource aggregator and the plurality of consumers.

[0020] For example, a consumer that owns a power generation facility transmits information about the amount of power generated by the power generation facility to the resource aggregator, and the resource aggregator transmits information about the amount of power reduction allocated to the consumer to the consumer.

[0021] The aggregation coordinator aggregates the amount of electricity controlled by the resource aggregator and trades adjustment power with businesses such as electricity transmission and distribution businesses or electricity retailers.

[0022] In such an energy control system 1001, the aggregator may control the energy resources of a consumer under desired control conditions based on a request from a general electricity transmission and distribution company, an electricity retailer, or a consumer. The desired control conditions are, for example, conditions based on an electric power service such as peak shaving or demand response (DR).

[0023] The aggregator may transmit a power command message to one energy resource to operate the energy resource under control conditions based on a plurality of power services. The aggregator may transmit a power command message to operate the energy resource under control conditions for realizing, for example, two power services, peak shaving and demand response. Note that the power service is not limited to peak shaving and demand response, and may be a service related to power provided in a specific country, a specific region, etc.

[0024] In this case, when the aggregator transmits a state restoration message to terminate one of the two power services, both power services may be terminated, i.e., control under the desired control conditions may not be terminated appropriately. For example, this may occur when the aggregator transmits one power command message that integrates two power services.

[0025] Therefore, the inventors of the present application have conducted extensive research into energy resource control methods and the like that can properly end control under desired control conditions, and have devised the energy resource control method and the like described below.

[0026] Peak shaving (peak shaving of electricity demand) refers to the restriction of electricity usage (consumption) by consumers during peak electricity demand times. In general, peak shaving is an electricity service that adjusts consumers' peak electricity to a specified power value (one example of a target power value) or less. Peak shaving is important because electricity suppliers need to install power generation facilities of a scale corresponding to the peak electricity demand. For this reason, contract power and basic charges are often set based on the maximum electricity demand in time units such as 30 minutes, and peak shaving also benefits consumers by reducing their electricity bills, making it an electricity service primarily for consumers.

[0027] Peak-cut control is performed for a longer period than, for example, demand response control, and is performed constantly, for example, 24 hours a day for a year.

[0028] Demand response (electricity demand response) refers to stabilizing the overall balance of power supply and demand, achieving planned simultaneous equalization, etc., by controlling the energy resources of consumers and changing the power demand pattern. Demand response also includes indirect control, such as setting the power rate higher during a specified period of power demand (e.g., peak time) than during non-peak times, or providing incentives (such as bonuses) to consumers for reducing power consumption by retail electricity companies, in addition to directly controlling energy resources. Demand response is an electric power service that adjusts the power of consumers during such a specified period to a specified power value (an example of a target power value).

[0029] Control for demand response is performed for a shorter period than peak cutting control, for example. Control for demand response is performed, for example, only for a few hours in a day when there is high power demand or power supply (for example, from 12:00 to 15:00). Demand response is, for example, a power service mainly for general power transmission and distribution businesses and retail electricity businesses. General power transmission and distribution businesses procure adjustment power from aggregators, etc. via the market or through bilateral contracts in order to adjust power supply and demand, etc., and retail electricity businesses procure adjustment power from aggregators, etc. in order to avoid imbalances, etc.

[0030] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components that are not described in the independent claims are described as optional components.

[0031] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0032] Furthermore, in this specification, terms indicating relationships between elements such as "same" and numerical values ​​and numerical ranges are not expressions that only indicate a strict meaning, but are expressions that also include a substantially equivalent range, for example, a difference of about a few percent (e.g., about 10%).

[0033] (Embodiment) Hereinafter, a method for controlling energy resources according to the present embodiment will be described with reference to FIGS.

[0034] [1. Energy control system configuration] First, the configuration of the energy control system according to the present embodiment will be described with reference to Figs. 2 to 4. Fig. 2 is a first diagram showing an overview of the energy control system 1 according to the present embodiment. Fig. 3 is a second diagram showing an overview of the energy control system 1 according to the present embodiment. Fig. 4 is a block diagram showing a functional configuration of an energy resource control device 10 according to the present embodiment. Note that, for convenience, only consumers 20 and 30 are shown in Fig. 3.

[0035] 2 and 3, an energy control system 1 according to the present embodiment includes an energy resource control device 10 and a plurality of consumers 20 to 50 (hereinafter also referred to as a plurality of consumers 20, etc.). The energy control system 1 is an energy control system in which the energy resource control device 10 controls the power demand of the energy resources of the plurality of consumers 20, etc.

[0036] Here, the energy resource is a device that can generate and / or consume energy (electricity) and can receive commands (messages) from the energy resource control device 10, and is hereinafter also referred to as a target device. A device that can receive commands via a controller or the like (not shown) is also referred to as a target device. A device that can generate and / or consume energy (electricity) but cannot receive commands (messages) from the energy resource control device 10 is hereinafter also referred to as a non-target device.

[0037] The energy resource control device 10 is connected to target devices (e.g., target devices 21 and 31) owned by multiple consumers 20, etc., so as to be able to communicate wirelessly or via wired communication, and transmits to the target devices a power command message (control command) for causing the target devices to perform control under desired control conditions, and a state restoration message (state restoration command) for stopping the control under the desired control conditions.

[0038] Here, restoration means transitioning the energy resource from a state in which it operates based on the control from the energy resource control device 10 to a state in which it is controlled by local control, etc. When a target device operating based on a control command from the energy resource control device 10 acquires a state restoration command, the target device ends the operation based on the control command and enters a state in which it cannot be controlled by the energy resource control device 10 until it acquires the next control command. Also, for example, when the target device is operating based on a control command from the energy resource control device 10, it does not have to be able to operate in an operating state such as an automatic operation state in which local control is performed until it acquires a state restoration command.

[0039] The energy resource control device 10 is, for example, an information processing device (server device) owned by a resource aggregator. The energy resource control device 10 may communicate with external servers such as servers of general electricity transmission and distribution companies, electricity retailers, weather information providers, and servers of supply and demand adjustment markets, but these are not shown in the drawings.

[0040] 4, the energy resource control device 10 includes an acquisition unit 11, a command generation unit 12, an output unit 13, and a storage unit 14. The energy resource control device 10 is realized by a computer including a communication interface for communicating with each target device, a volatile memory which is a temporary storage area for executing a program, an input / output port for transmitting and receiving signals, a processor for executing the program, etc. Each function of the energy resource control device 10 is realized by the processor executing the program.

[0041] The acquisition unit 11 acquires measurement data including at least one of data on power (peak power) at a power receiving point of a customer facility (e.g., a residence) and input / output power of one or more target devices. The acquisition unit 11 may acquire the measurement data from each of the multiple target devices, or may acquire the measurement data from a controller that controls the multiple target devices. The acquisition unit 11 is configured to include, for example, a communication interface.

[0042] The measurement data may include data on the amount of power generated, the amount of power stored, the amount of hot water stored, the amount of usage, the operation mode, etc. of the target device.

[0043] The power data at the receiving point of the consumer's facility is the power or the amount of power at the receiving point of the facility with the power system 100 (see FIG. 3). The power is, for example, the peak power supplied from the power system 100 to the consumer's facility. In the case of the consumer 20, the power is the maximum value of the power used by the consumer 20. The peak power can be obtained, for example, by a sensor that measures the power supplied from the power system 100. The power and the amount of power are, for example, time series data of the forward or reverse power flow from the power system 100 to the consumer's facility.

[0044] The input / output power of one or more target devices includes power supplied from the power system 100 to one or more target devices (e.g., consumed or stored power) or power supplied by one or more target devices (e.g., generated or discharged power). The power can be acquired by a sensor that measures the power input or output to each of the one or more target devices.

[0045] The facility is not limited to a residence, but may be an apartment building, a building, a hospital, a school, or any other building in which the target device is installed.

[0046] The command generating unit 12 generates various commands for controlling the target devices. The command generating unit 12 generates the above-mentioned power command message (control command) and state restoration message (state restoration command). The command generating unit 12 generates the power command message based on, for example, measurement data and contract details. For example, the command generating unit 12 generates a control command for each of one or more target devices in accordance with the contents of a contract regarding power between a consumer who owns the target device and an aggregator or a command from a general electricity transmission and distribution company, an electricity retailer, or the like.

[0047] Furthermore, the command generating unit 12 generates a state restoration command based on the input / output, state, contract details, etc. of the target device. The command generating unit 12 does not generate a state restoration command uniformly for each of the one or more target devices, but generates a state restoration command only for a target device that satisfies a predetermined condition among the one or more target devices. The predetermined condition is that the target device is not participating in another power service at or after the end of one power service.

[0048] The command generating unit 12 is realized by a processor or the like.

[0049] The output unit 13 outputs the command generated by the command generating unit 12 to a target device corresponding to the command. The output unit 13 transmits the command by wireless communication, for example. The output unit 13 includes, for example, a communication interface. The output unit 13 is an example of a command transmitting unit.

[0050] The storage unit 14 stores various information used for generating commands in the command generating unit 12. The storage unit 14 stores information for identifying the multiple consumers 20, etc., service contents related to the power demand contracted by the multiple consumers 20, etc., a list of target devices owned by the multiple consumers 20, etc. The storage unit 14 may also store measurement data acquired by the acquisition unit 11, commands generated by the command generating unit 12, etc. The storage unit 14 is realized by, for example, a semiconductor memory, etc., but is not limited to this.

[0051] 2 and 3 again, each of the multiple consumers 20 etc. has one or more target devices (one or more energy resources) and is a consumer that has a contract to be controlled by the energy resource control device 10. The one or more target devices of the multiple consumers 20 etc. are controlled by the energy resource control device 10 according to the contents of the contract.

[0052] In addition, the multiple consumers 20, etc. may be consumers included in one group (community) (for example, consumers A1 to A3, etc. shown in Figure 1) or consumers included in different groups (for example, consumers A1, B1, C1, etc. shown in Figure 1).

[0053] 3, consumer 20 has target equipment 21 and non-target equipment 22, and consumer 30 has target equipment 31 and non-target equipment 32. Note that the configurations of other consumers 30, 40, and 50 are similar to those of consumer 20 or 30, and description thereof will be omitted. Furthermore, the number of target equipment and non-target equipment possessed by each of the multiple consumers 20, etc. is not particularly limited, and each may be two or more.

[0054] Examples of the target devices 21 and 31 include solar cells (power generation equipment), secondary batteries such as storage batteries (storage battery equipment), electric vehicles, electric water heaters (hot water storage equipment) using heat pump technology such as EcoCute (registered trademark), and devices (load equipment) such as air conditioners and refrigerators. Each of the target devices 21 and 31 is communicatively connected to the energy resource control device 10 directly or via a controller or the like. It is sufficient that the energy control system 1 includes at least one target device. It is noted that, hereinafter, for the sake of distinction, the target device 21 may be referred to as a first target device 21, and the target device 31 may be referred to as a second target device 31.

[0055] The non-target devices 22 and 32 are devices that cannot be controlled by the energy resource control device 10, and examples of such devices include a hairdryer and a hair clipper. For example, the non-target devices 22 and 32 do not have a communication function. Note that there may be cases where the energy resource control device 10 does not control a solar cell (power generation equipment), in which case the solar cell becomes a non-target device.

[0056] [2. Operation of the Energy Control System] Next, the operation of the energy control system 1 configured as above will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is a flowchart showing the operation (energy resource control method) of the energy resource control device 10 according to this embodiment. Note that, hereinafter, a plurality of target devices including the target devices 21 and 31 will also be described as a plurality of target devices 21, etc. Also, hereinafter, an operation in the case of reducing the amount of power used by a plurality of target devices 21, etc. will be described. Also, the energy resource control method is a control method for providing one or more power services including one power service for adjusting the power value in one or more target devices (one or more energy resources) to a target power value.

[0057] 5, the acquisition unit 11 acquires measurement data from a plurality of target devices 21, etc. (S11). The acquisition unit 11 acquires measurement data from the target devices 21, etc. installed in each of the plurality of consumers 20, etc., regardless of the contents of the power service contract for each of the plurality of consumers 20, etc. Step S11 is an example of a data receiving step.

[0058] The acquisition unit 11 acquires the measurement data at predetermined time intervals, for example, but the acquisition timing is not limited to this. In addition, the measurement data may be acquired in parallel while steps S12 to S21 described later are being executed.

[0059] The acquiring unit 11 outputs the acquired measurement data to the command generating unit 12. The command generating unit 12 may store the measurement data in the storage unit .

[0060] Next, the command generating unit 12 judges whether or not the power service is being provided (S12). The command generating unit 12 makes the judgment in step S12 based on whether or not the current time is included in the period covered by the power service. If the power service is being provided (Yes in S12), the process proceeds to step S13, and if the power service is not being provided (No in S12), the process proceeds to step S21.

[0061] Next, if the power service is currently being performed (Yes in S12), the command generating unit 12 calculates a control amount (S13). The control amount is, for example, a value of power or power amount calculated using measurement data. The command generating unit 12 calculates the overall reduction or increase amount of power in one or more consumers 20 managed by the energy resource control device 10 as the control amount based on information based on the measurement data and the contents of the power service (for example, an upper limit value of power usage, a command value from an external server, etc.). The command generating unit 12 may, for example, calculate the total power usage in multiple consumers 20 based on information based on the measurement data, and calculate the difference between the calculated total power usage (total usage amount) and the power usage (allowable usage amount) permitted in the power service as the control amount. Note that when control is not required, the control amount is 0.

[0062] The information based on the measurement data may include, for example, at least one of the power at the receiving point of each facility of the multiple consumers 20, etc. with the power grid 100 (see Figure 3), the total power at multiple receiving points bundling the facilities of each facility of the multiple consumers 20, etc., the input / output power of each of one or more target devices installed in the facility, and the total input / output power of each of the one or more target devices of the multiple consumers 20, etc.

[0063] The power at the power receiving point is, for example, the power of the facility, and the total power is, for example, the total value of the power of each facility. The input / output power is, for example, the charging power and discharging power of the target devices 21 and 31, and the total input / output power is, for example, the total value of the charging power and discharging power of each of the multiple target devices 21, etc.

[0064] The allowable amount of power is the total amount of power that the power system 100 can supply to each of the multiple consumers 20, etc. For example, an allowable amount of usage is set for each time period. The allowable amount of power is, for example, a threshold (upper limit) for the amount of power that can be supplied from the power system 100.

[0065] When there are multiple power services currently being implemented, the command generating unit 12 calculates the control amount based on the allowable usage amount of each of the multiple power services. The command generating unit 12 also calculates the control amount for each time period, for example. Any known method may be used to calculate the control amount.

[0066] Next, the command generating unit 12 selects an energy resource (target device) to be controlled (S14). The command generating unit 12 selects one or more target devices installed in one or more consumers participating in the currently implemented power service as the energy resource to be controlled, based on the contract details of the multiple consumers 20, etc. stored in the storage unit 14.

[0067] In step S14, target devices that cannot implement the power service or whose implementation is limited may not be selected as energy resources to be controlled. In other words, in step S14, it is determined whether the target devices are target devices that can implement the power service being implemented, and only target devices that can implement the power service may be selected as energy resources to be controlled. For example, when reducing the amount of power supplied from the power system 100, it is possible to control a secondary battery, which is an example of a target device, to discharge it. Therefore, a secondary battery whose stored amount or dischargeable amount is 0 or less than a predetermined value may not be selected as an energy resource to be controlled. Target devices that participate in the power service but cannot be controlled by the energy resource control device 10 and target devices installed in consumers that do not participate in the power service are excluded from the energy resources to be controlled.

[0068] Next, the command generating unit 12 determines an operation mode and a command value for the selected energy resource so as to achieve the control amount calculated in step S13, and generates a control command for operating the selected energy resource in the determined operation mode and command value (S15). In step S15, the command generating unit 12 determines an allocation of command values ​​for each consumer from the overall control amount (e.g., reduction amount) of one or more consumers 20, etc. managed by the energy resource control device 10. Step S15 is an example of a control command generating step.

[0069] The control command is generated, for example, by using a control amount. In other words, the control command is generated, for example, by using at least measurement data. That is, the command generating unit 12 generates a control command for controlling one or more target devices, for example, by using at least measurement data. Furthermore, the command generating unit 12 may further generate a control command for controlling one or more target devices based on an ongoing power service.

[0070] The operation mode is a mode in which the target device is operated, and includes, but is not limited to, an energy saving mode, a power storage mode, a discharge mode, a heating mode, a cooling mode, and the like. The command value includes, but is not limited to, a reduction amount of power, a power storage amount, a discharge amount, and an allowable power amount. The unit of the command value includes, but is not limited to, W, Wh, A, Ah, and the like. The command generation unit 12 allocates the command value to the selected energy resource so as to achieve the control amount. For example, the control command is generated for one or more target devices that satisfy a predetermined condition. In the case of an energy resource that can only set an operation mode, or when control of only an operation mode such as standby or stop is sufficient, only the operation mode is generated as the control command. That is, in this case, the control command does not need to include a command value, etc.

[0071] In this manner, the command generating unit 12 functions as a control command generating unit that generates a control command. The command generating unit 12 outputs the generated control command to the output unit 13.

[0072] Next, the output unit 13 transmits the control command acquired from the command generating unit 12 to one or more target devices or controllers (S16). Step S16 is an example of a command transmitting step.

[0073] Next, the command generating unit 12 judges whether or not it is the timing to transmit a state restoration command (S17). For example, if the time is a predetermined time, the end time of the power service being performed, or the time elapsed since the last transmission of the state restoration command has exceeded a predetermined time, the command generating unit 12 judges that it is the timing to transmit a state restoration command (Yes in S17) and proceeds to step S18, and if not, it judges that it is not the timing to transmit a state restoration command (No in S17) and proceeds to step S11 without selecting an energy resource to be restored to state. Note that the end time of the power service being performed also includes a time a predetermined period before the end time of the power service (for example, time t3 shown in FIG. 6). The predetermined period here is set in advance based on, for example, the time required for the processing shown in FIG. 5, the time required for communication between the energy resource control device 10 and the target device, and the like.

[0074] Next, when it is time to send a state restoration command (Yes in S17), the command generating unit 12 selects an energy resource to be restored to its state (S18). The command generating unit 12 selects one or more target devices installed in a participating consumer whose power service has ended as the energy resource to be restored to its state.

[0075] Here, when a consumer participates in multiple power services, the command generating unit 12 selects one or more target devices installed in the consumer where all of the multiple power services have been completed as energy resources to be restored to their states. For example, when there are multiple power services including a first power service, the command generating unit 12 extracts, from among the multiple consumers 20, consumers that do not participate in any power service other than the first power service at or after the end of the first power service, and selects one or more target devices installed in the extracted one or more consumers as energy resources to be restored to their states. In other words, the command generating unit 12 does not select one or more target devices installed in a consumer where a power service other than the first power service is being implemented at the end of the first power service, as energy resources to be restored to their states.

[0076] In addition, not participating in the service includes at least one of the following cases: a consumer in which the energy resource is installed is not covered by other power services (is not participating in other power services), and a consumer in which the energy resource is installed is covered by other power services but the energy resource has no spare capacity (e.g., remaining capacity) and cannot be controlled by the energy resource control device 10.

[0077] Next, the command generating unit 12 determines the restoration state of one or more target devices after the end of the first power service among the multiple power services, and generates a state restoration command for controlling the one or more target devices in the determined restoration state. Specifically, the command generating unit 12 determines an operation mode and a command value after restoration for the target devices selected in step S18, and generates a state restoration command for operating the target devices in the determined operation mode and command value (S19). For example, the command generating unit 12 generates a state restoration command only for an energy resource that does not participate in a power service different from the first power service among the one or more target devices after the end of the first power service. That is, the command generating unit 12 does not generate a state restoration command for each of the multiple target devices uniformly. The command generating unit 12 does not generate a state restoration command for all of the one or more consumers that participated in the first power service. Step S19 is an example of a state restoration command generating step. Also, determining an operation mode and a command value after restoration is an example of determining a restoration state. The unit of the command value includes, but is not limited to, W, Wh, A, Ah, etc. The command value may be, for example, a target remaining capacity value (%), etc. In the case of an energy resource for which only an operation mode can be set, or when control of only an operation mode such as standby, stop, and automatic operation is sufficient, only the operation mode is generated as a control command. In other words, in this case, the control command does not need to include a command value, etc.

[0078] For example, when providing an electric power service that adjusts the electric power at the power receiving point of a facility in which one or more target devices are installed to a predetermined power value or less, the energy resource control device 10 does not generate a state restoration command for one or more target devices installed in the facility. The electric power service is a so-called peak cut, and the electric power service is always provided. Therefore, the command generating unit 12 does not generate a state restoration command for one or more target devices installed in a consumer who has contracted for the electric power service. In this way, in step S19, the command generating unit 12 may determine whether or not to generate a state restoration command based on whether or not the consumer in which the selected target device is installed participates in a predetermined electric power service. Also, the command generating unit 12 may determine whether or not to generate a state restoration command based on whether or not the consumer in which the selected target device is installed participates in a predetermined electric power service and whether or not control related to the electric power service is activated.

[0079] The recovery state is determined, for example, as follows: The recovery state is determined, for example, according to the type of the target device.

[0080] For example, when one or more target devices include a secondary battery, the command generating unit 12 may determine at least one of a standby state, an automatic operation state, and a state opposite to the control command generated in step S15 as the return state for the secondary battery. The standby state is, for example, a state in which the secondary battery is not charged or discharged and control by a control command from the energy resource control device 10 can be started. The automatic operation state is a normal operation state of the secondary battery, for example, a state in which the secondary battery operates based on preset schedule information or algorithm. The automatic operation state can also be said to be a state in which the secondary battery operates under conditions determined on the secondary battery side (for example, a controller) regardless of the control command from the energy resource control device 10. Which state is to be the return state may be determined in advance by a contract or the like, for example, or may be determined according to the state of the secondary battery when it returns.

[0081] Also, for example, the opposite state to the control command generated in step S15 is a state in which the secondary battery is charged if a control command to discharge the secondary battery was generated in step S15. Furthermore, if one or more target devices include a secondary battery, the command generating unit 12 may further determine at least one value of the input and output of power (input / output power) in the restored state, and generate a state restore command including the determined value. The input value is, for example, the amount of charge, and the output value is, for example, the amount of discharge.

[0082] Furthermore, for example, when one or more target devices include a device having a heat storage function (for example, an electric water heater), the command generating unit 12 may determine an automatic operation state in which local control is performed as the restoration state for the device.

[0083] Furthermore, for example, when one or more target devices include a device having a power generation function (for example, a generator), the command generating unit 12 may determine an automatic operation state in which local control is performed as the restoration state for the device.

[0084] In this way, the command generating unit 12 functions as a state restoration command generating unit that generates a state restoration command. The command generating unit 12 outputs the generated state restoration command to the output unit 13.

[0085] Next, the output unit 13 transmits the state restoration command acquired from the command generating unit 12 to one or more target devices or controllers (S20). After transmitting at least one of the control commands generated in step S15 to one or more target devices, the output unit 13 transmits the state restoration command generated in step S19 to the one or more target devices. Step S20 is an example of a command transmitting step.

[0086] Next, the command generating unit 12 judges whether or not the current time is the next control period (S21). The control period is a period for generating and transmitting a control command, and is set in advance. The control period may be, for example, one minute, ten minutes, or one hour. For example, when a consumer introduces a real-time electricity pricing system (RTP) in which the unit price of electricity is changed at short intervals such as every 30 minutes, the control period may be set to a period shorter than the short period. If the current time is the next control period (Yes in S21), the command generating unit 12 proceeds to step S11 and performs a series of processes from step S11 again. If the current time is not the next control period (No in S21), the command generating unit 12 returns to step S21 and waits until the next control period.

[0087] It is to be noted that the determination in step S17 shown in Fig. 5 does not have to be performed. In other words, the processes in and after step S18 may be executed every time a control command is transmitted.

[0088] The output unit 13 may transmit the control command and the status restoration command to one or more target devices in the same message format. In other words, the command generation unit 12 may generate the control command and the status restoration command using the same message format.

[0089] Note that steps S13 to S16 and steps S17 to S20 may be performed in parallel.

[0090] Next, the operation of the energy control system 1 will be described with reference to Fig. 6. Fig. 6 is a sequence diagram showing the operation (method of controlling energy resources) of the energy control system 1 according to the present embodiment. Fig. 6 illustrates a control method in the case where one or more power services include a first power service and a second power service. The first power service starts before the start time of the second power service and ends after the second power service ends. The second power service is a power service whose end time falls during the control period of the first power service. The first power service is an example of another power service, and the second power service is an example of one power service.

[0091] The first target device 21 is an energy resource installed in the consumer 20, and participates in both the first power service and the second power service. In other words, the consumer 20 participates in both the first power service and the second power service. The second target device 31 is an energy resource installed in the consumer 30, and participates in only the second power service of the first power service and the second power service. In other words, the consumer 30 participates in only the second power service of the first power service and the second power service. The first target device 21 and the second target device 31 are examples of one or more energy resources.

[0092] Also, time t1 shown in the figure indicates the start time of the first power service, time t2 indicates the start time of the second power service, time t3 indicates the end time of the second power service, and time t4 indicates the end time of the first power service. Time passes in the order of times t1, t2, t3, and t4. The period from time t1 to time t4 is the control period of the first power service, and the period from time t2 to time t3 is the control period of the second power service. Note that the second power service may be a power service whose start time is set before time t1.

[0093] The first power service is, for example, a power service that is implemented for a long period of time or all the time, such as peak shaving. The second power service is, for example, a power service that is implemented only for a period of about a few hours, such as demand response (for example, three hours in the case of tertiary adjustment capacity (2) in the supply and demand adjustment market).

[0094] First, at time t1, a first power service is started. When the operation shown in Fig. 5 is executed at time t1, the energy resource control device 10 generates a first control command corresponding to the first power service for the first target device 21 and transmits the generated first control command to the first target device 21.

[0095] This allows the energy resource control device 10 to perform control according to the first power service on the first target device 21. Note that the second target device 31 that does not participate in the first power service is not selected in step S14 shown in Fig. 5, and therefore a control command according to the first power service is not transmitted to the second target device 31 at time t1.

[0096] The energy resource control device 10 transmits the first control command to the first target device 21 at each control period until time t2. If there is no change in the control content from the previously transmitted first control command, the energy resource control device 10 may not transmit the first control command. This allows the energy resource control device 10 to reduce the amount of communication between the energy resource control device 10 and the target device.

[0097] Next, at time t2, the second power service is started. When the operation shown in Fig. 5 is executed at time t2, the energy resource control device 10 generates a second control command corresponding to the first power service and the second power service for the first target device 21, transmits the generated second control command to the first target device 21, and generates a third control command corresponding to the second power service for the second target device 31, and transmits the generated third control command to the second target device 31. It can also be said that the energy resource control device 10 switches the control command to be transmitted to the first target device 21 from the first control command to the second control command at time t2. The first control command and the second control command are control commands having the same transmission destination and differing from each other in at least one of the operation mode and the command value.

[0098] As a result, the energy resource control device 10 can perform control on the first target device 21 in accordance with the first power service and the second power service, and can perform control on the second target device 31 in accordance with the second power service.

[0099] In step S14 executed at time t2, the energy resource control device 10 selects the first target device 21 and the second target device 31 as energy resources to be controlled. If the target device participates in at least one of a plurality of power services being implemented, the energy resource control device 10 selects the target device as an energy resource to be controlled.

[0100] Then, in step S15, the energy resource control device 10 determines, for the first target device 21, an operating mode and command values ​​corresponding to the first power service and the second power service, and determines, for the second target device 31, an operating mode and command values ​​corresponding to the second power service.

[0101] 6, for convenience, the second control command and the third control command are illustrated as being transmitted at different timings, but in reality, the second control command and the third control command are transmitted at the same timing. A selection process may be performed according to priority, such as transmitting the second control command or the third control command with a larger command value first.

[0102] The energy resource control device 10 transmits the second control command to the first target device 21 and transmits the third control command to the second target device 31 for each control period during the period from time t2 to time t3.

[0103] Next, at time t3, the second power service ends. When the operation shown in Fig. 5 is executed at time t3, the energy resource control device 10 generates a first control command corresponding to the first power service for the first target device 21 and transmits the generated first control command to the first target device 21. In step S15 executed at time t3, the energy resource control device 10 determines an operation mode and a command value corresponding to the first power service in which the control period is continuing for the first target device 21. In addition, in step S14 executed at time t3, the energy resource control device 10 does not select the second target device 31 as an energy resource to be controlled because the participating power service is not being implemented.

[0104] Furthermore, when time t3 is the timing to transmit a state restoration command (Yes in S17), the energy resource control device 10 selects the second target device 31 as an energy resource to be restored to its state in step S18. The energy resource control device 10 determines that the second target device 31, which is a device in which a participating power service is not being implemented and which has not transmitted a state restoration command, is an energy resource to be restored to its state. Furthermore, in step S18 executed at time t3, the energy resource control device 10 determines that the first target device 21, which is a device in which at least one of the participating power services is being implemented, is not an energy resource to be restored to its state.

[0105] Then, in step S19, the energy resource control device 10 generates a state restoration command only for the second target device 31 selected in step S18 out of the first target device 21 and the second target device 31.

[0106] As a result, since a state restoration command is not transmitted to the first target device 21, the energy resource control device 10 can prevent the control according to the first power service from being terminated in the first target device 21 during the implementation period of the first power service. Furthermore, since a state restoration command is transmitted to the second target device 31, the energy resource control device 10 can terminate the control according to the second power service in the second target device 31. Thus, the energy resource control device 10 can appropriately terminate the control under the desired control conditions. After time t3, the second target device 31 operates in any one of a standby state, an automatic operation state, and a state opposite to the control command acquired at time t2 to time t3 until it next acquires a control command from the energy resource control device 10.

[0107] Next, at time t4, the first power service ends. At time t4, the energy resource control device 10 executes the operation shown in Fig. 5, and therefore does not select the first target device 21 as an energy resource to be controlled in step S14 because the participating power service is not being implemented. Furthermore, if time t4 is the timing for transmitting a state restoration command (Yes in S17), the energy resource control device 10 selects the first target device 21 as an energy resource to be restored to state in step S18. The energy resource control device 10 determines that the first target device 21, which is a device in which a participating power service is not being implemented and which has not transmitted a state restoration command, is an energy resource to be restored to state.

[0108] Then, in step S19, the energy resource control device 10 generates a state restoration command only for the first target device 21 selected in step S18 out of the first target device 21 and the second target device 31.

[0109] As a result, a state restoration command is transmitted to the first target device 21, and the energy resource control device 10 can end the control according to the first power service in the first target device 21. Therefore, the energy resource control device 10 can appropriately end the control under the desired control conditions in the first target device 21. After time t4, until the first target device 21 next acquires a control command from the energy resource control device 10, the first target device 21 operates in any one of a standby state, an automatic operation state, and a state opposite to the control command acquired at time t1 to time t4.

[0110] [3. Effects, etc.] As described above, the energy resource control method according to the present embodiment is a method for controlling energy resources that provides two or more power services for adjusting the power value of one or more energy resources to a target power value. The two or more power services include one power service and other power services different from the one power service. The energy resource control method includes a control command generating step (S15) for generating a control command for controlling one or more energy resources, a state restoration command generating step (S19) for determining a restoration state of one or more energy resources after the end of one power service among the two or more power services and generating a state restoration command for controlling the one or more energy resources in the determined restoration state, and a command transmitting step (S16, S20) for transmitting the control command generated in the control command generating step to the one or more energy resources and then transmitting the state restoration command generated in the state restoration command generating step to the one or more energy resources. Then, in the state restoration command generating step (S19), a state restoration command is generated for an energy resource that does not participate in another power service among the one or more energy resources at the end of one power service.

[0111] As a result, a state restoration command is not transmitted to the energy resource participating in a power service different from the first power service. Therefore, according to the energy resource control method, at the end of the first power service, the control by the control command of the energy resource not participating in the different power service can be ended, so that the control under the desired control condition can be ended appropriately.

[0112] The other power services include a power service that adjusts the power at the power receiving point of the facility in which the one or more energy resources are installed to a predetermined power value or less. In the state restoration command generating step (S19), when the other power services are provided for the one or more energy resources installed in the facility, a state restoration command is not generated for the one or more energy resources.

[0113] As a result, for an energy resource participating in the second power service that is constantly or long-term controlled, when the first power service ends, the energy resource control device 10 does not generate a state restoration command. That is, it is possible to prevent the second power service from ending due to a state restoration command in the energy resource. Therefore, according to the energy resource control method, it is possible to more reliably end control under desired control conditions appropriately.

[0114] In addition, in the state return command generation step (S19), if one or more energy resources include a secondary battery, at least one of a standby state, an automatic driving state performing local control, and a state opposite to the control command generated in the control command generation step (S15) is determined as the return state for the secondary battery.

[0115] This makes it possible to return the energy resource to any one of a standby state, an automatic operation state, or a state opposite to the control command, thereby improving the convenience of the method for controlling the energy resource.

[0116] Furthermore, in the state restoration command generating step (S19), if a state opposite to the control command generated in the control command generating step (S15) is determined as the restoration state, at least one of the values ​​of the power input and output (input / output power) in the restoration state is further determined, and a state restoration command including the determined value is generated.

[0117] This makes it possible to set the state of the energy resource after the end of the power service to a desired state when the restored state is the opposite state to that of the control command, thereby further improving the convenience of the energy resource control method.

[0118] Moreover, in the state restoration command generating step (S19), if one or more energy resources include a device having a heat storage function, the automatic operation state in which local control is performed is determined as the restoration state for that device.

[0119] This allows the device to boil hot water when the temperature of the hot water is low. For example, it is possible to prevent disruptions to the user's life, such as being unable to use hot water, due to participation in the power service.

[0120] Moreover, in the command transmission steps (S16, S20), a control command and a state restoration command are transmitted to one or more energy resources in the same message format.

[0121] This allows the control command and the status restoration command to be transmitted using a common message format, which makes it easier to transmit the commands than when the control command and the status restoration command use different message formats.

[0122] The energy resource control method further includes a data receiving step (S11) of receiving measurement data measuring at least one of the power at a power receiving point of the facility and the input / output power of the one or more energy resources from one or more energy resources installed in the facility or a controller controlling the one or more energy resources. Then, in a control command generating step (S15), a control command is generated using at least the measurement data.

[0123] As a result, a control command is generated based on the measurement data, and therefore, according to the energy resource control method, the content of the control command (for example, the operation mode and the command value) can be more appropriately determined.

[0124] As described above, the energy resource control device 10 (an example of a control device) according to the present embodiment is a control device for providing two or more power services for adjusting the power value of one or more energy resources to a target power value. The two or more power services include one power service and another power service different from the one power service. The energy resource control device 10 includes a command generating unit 12 (an example of a control command generating unit) that generates a control command for controlling one or more energy resources, a command generating unit 12 (an example of a state return command generating unit) that determines a return state of one or more energy resources after the end of one power service among the two or more power services and generates a state return command for controlling the one or more energy resources in the determined return state, and an output unit 13 (an example of a command transmitting unit) that transmits the control command generated by the command generating unit 12 to the one or more energy resources and then transmits the state return command generated by the command generating unit 12 to the one or more energy resources. The command generating unit 12 generates a state return command for an energy resource that does not participate in another power service at the end of one power service among the one or more energy resources. As described above, the program according to the present embodiment is a program for causing a computer to execute the above-described energy resource control method.

[0125] This provides the same effects as the above-mentioned energy resource control method.

[0128] In the above embodiment, an example is described in which a control command including a command to reduce power consumption is output as a control command, but the content of the control command is not limited to this, and may be, for example, a command to increase power consumption or to increase the amount of stored power. For example, when there is a surplus of power, control such as increasing the amount of stored power is performed.
