DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection forms, steps, and step order 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 not recited in independent claims will be described as optional components.

[0011] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0012] (Embodiment) [overview] FIG. 1 is a diagram listing power services provided to electric utilities or consumers in the integrated management and control of distributed energy resources. One specific example of the integrated management and control of distributed energy resources is the concept of a virtual power plant (VPP). A VPP is a concept that virtually aggregates small-scale power generation facilities, energy storage facilities, and demand facilities (i.e., consumer-side energy resources) owned by businesses (i.e., consumers), such as general households and non-electric utilities, and treats them as a single large power plant to adjust the balance of power supply and demand in the market. To achieve this goal, VPPs operate various power services, such as reducing power consumption by demand facilities and discharging and generating power from energy storage facilities or power generation facilities. Naturally, each power service controls different consumer-side energy resources. Note that FIG. 1 also lists power services that may be launched in the future. Although the following embodiments will focus on consumer-side energy resources, the energy resources are not limited to consumer-side energy resources.

[0013] FIG. 2 is a diagram for explaining the connection mode between the components surrounding the energy resource management system according to the embodiment.

[0014] FIG. 2 shows variations in the connection topology of a general consumer-side energy resource. As shown in the figure, the consumer-side energy resource 62 has a variety of connection topology, such as connection topology A, connection topology B, and connection topology C. Specifically, in connection topology A, a management controller 61 in a consumer 60a receives a control command (or a command value indicating a specific control amount, etc.) from an electric utility 91 or an electric power-related market 92, and controls the consumer-side energy resource 62. In connection topology B, a control command from an electric utility 91 or an electric power-related market 92 is received by an energy management server 70 (a processing server for an energy management system) outside the consumer 60b, and is further received by the management controller 61 in the consumer 60b, and controls the consumer-side energy resource 62. In connection topology C, a control command from an electric utility 91 or an electric power-related market 92 is received by an energy management server 70 outside the consumer 60c, and controls the consumer-side energy resource 62 in the consumer 60c. As described above, the consumer-side energy resource 62 has various connection topologies, and it is necessary to convert the received command into an appropriate control command depending on the connection topology and deliver it to the consumer-side energy resource 62. Note that the connection topologies may be other than the above-mentioned connection topologies A, B, and C.

[0015] However, in the current situation where each consumer receives various power services and connects various devices as consumer-side energy resources 62 in different connection forms, assembling such appropriate control commands is complicated. Therefore, in the present invention, at least one of the first control server 80 and the second control server 10, which exchange information between the electric utility 91 or the power-related market 92 and the consumers 60a to 60c (or the energy management server 70), is equipped with a function for autonomously assembling a control command. This makes it possible to autonomously generate a control command and control the consumer-side energy resources 62 depending on the connection form in which the consumer-side energy resources 62 are connected and the type of power service being used on the side closer to the consumers 60a to 60c than the first control server 80 and the second control server 10. In other words, the consumer-side energy resources 62 can be controlled more easily.

[0016] In the following embodiment, an example will be described in which the second control server 10 is equipped with the above functions. The first control server 80 has the function of relaying control commands received from an electric utility 91 or an electric power-related market 92 and outputting them to the second control server 10, and outputting service provision information related to the electric power service to be provided to the second control server 10. Such functional division is suitable, for example, when the first control server 80 and the second control server 10 are servers with roles as shown in FIG. 3. FIG. 3 is a diagram illustrating specific examples of the first control server and the second control server according to the embodiment. As shown in FIG. 3, as an example, in Case A, the first control server 80 is realized as a business server of an AC (Aggregation Coordinator). In that case, the second management server 10 is realized as a business server of an RA (Resource Aggregator) and a control PFer (Platformer). As another example, as shown in Case B, the first control server 80 is realized as a business server of the AC and the RA. In other words, in this case, the AC and the RA may be the same business server. In this case, the second management server 10 is realized as a business server of the control PFer.

[0017] Incidentally, the presence or absence of control functions for control in response to commands in each of the connection topologies described using FIG. 2 can be further subdivided as shown in FIG. 4. FIG. 4 is a diagram for explaining variations in control functions in each connection topology. In FIG. 4, consumer A corresponds to consumer 60a in connection topology A, consumer B corresponds to consumer 60b in connection topology B, and consumer C corresponds to consumer 60c in connection topology C. Also, in FIG. 4, a circle indicates the presence of a control function. For example, case 1 indicates that the management server (second management server 10 in this embodiment) has the control function. While it is not generally assumed that the management server does not have the control function, if each consumer has the control function, it is also possible to configure the management server not to have the control function (not shown). As shown in the figure, for the three connection topologies described above, the control functions can be allocated to each section in 14 cases.

[0018] [composition] Next, the configuration of an energy resource management system according to an embodiment and the data configuration of data transmitted and received in each configuration will be described with reference to Figures 5 to 12. The energy resource management system is realized by a first management server 80 and a second management server 10, or by the second management server 10 alone.

[0019] Fig. 5 is a block diagram showing the functional configuration of a second management server according to an embodiment Fig. 6 is a block diagram showing the functional configuration of a management controller according to an embodiment.

[0020] The second management server 10 includes a device information acquisition unit 11, a connection topology information acquisition unit 12, a control function layout information acquisition unit 13, a provided service information acquisition unit 14, a command value acquisition unit 15, a unit price information acquisition unit 16, a control unit 17, and an output unit 18. The second management server 10 can fulfill each of the above functions by executing a predetermined program using a processor and memory. The control unit 17 generates a control command from the information acquired by the device information acquisition unit 11, the connection topology information acquisition unit 12, the control function layout information acquisition unit 13, the provided service information acquisition unit 14, the command value acquisition unit 15, and the unit price information acquisition unit 16, and outputs the generated control command from the output unit 18.

[0021] The device information acquisition unit 11 is a functional unit that acquires device information related to the consumer-side energy resources 62. The device information is dynamic information for identifying the current operating status of each device of the consumer-side energy resources 62, and is information indicating, for example, the operating mode, such as the cooling mode or heating mode, and the set temperature of an air conditioner, the amount of power generated by a power generation facility, and the discharged power and remaining capacity of a storage battery. The device information also includes measurement data from power meters, distribution boards, and other power measuring instruments. The device information serves as a judgment index for determining whether to supply generated power to the market based on the current operating status of the device, and whether the set temperature can be changed to reduce power demand, and thus whether there is room for controlling the device.

[0022] The connection mode information acquiring unit 12 is a functional unit that acquires connection mode information related to the connection mode of the consumer-side energy resource 62. FIGS. 7 and 8 are diagrams illustrating data configurations of the connection mode information according to the embodiment. As shown in FIG. 7, the connection mode information associates a consumer ID for identifying a consumer from other consumers with information about the connection mode for identifying the connection mode of each consumer. Although shown as blank in FIG. 7, the connection information is information necessary for connecting to the management controller 61 or the energy management server 70. As shown in FIG. 8, the connection mode information associates a consumer ID, an appliance ID for identifying an appliance corresponding to each appliance of the consumer-side energy resource 62 from other appliances, an appliance type for identifying the appliance type, and information about the fixed performance of the appliance (e.g., rating information). That is, the appliance information acquiring unit 11 acquires dynamic information of the consumer-side energy resource 62, and the connection mode information acquiring unit 12 acquires static information of the consumer-side energy resource 62.

[0023] The control function location information acquisition unit 13 is a functional unit that acquires control function location information regarding the location of control functions used to control the consumer-side energy resources 62. FIG. 9 is a diagram showing the data configuration of control function location information according to an embodiment. As shown in the figure, the control function location information associates a consumer ID with an electricity service type ID for distinguishing the type of electricity service from other electricity service types. The control function location information can be said to be information for identifying where the management function is located when each consumer uses each electricity service. Note that in the example shown in the figure, for simplicity, it is assumed that the control functions are not located in multiple locations for the same consumer for the same service, but the control functions may be located in multiple locations.

[0024] The provided service information acquisition unit 14 is a functional unit that acquires provided service information related to the electricity service. FIG. 10 is a diagram illustrating the data configuration of the provided service information according to an embodiment. As illustrated in the figure, the provided service information associates an electricity service ID for distinguishing the electricity service from other electricity services, an electricity service type ID, a start date and time, an end date and time of the electricity service, and information about incentives for using the electricity service. Some electricity services start and end within a specific period, while others are provided constantly (there is essentially no start date and end date and time). Here, as examples of electricity services, a demand response with an electricity service ID of “DR0000001,” i.e., an electricity service in which incentives are provided according to the amount of electricity reduced (or increased) over a certain period, and a peak cut with an electricity service ID of “PC0000001,” i.e., an electricity service in which control is exercised to reduce electricity during peak hours every day, are illustrated. The electricity services are not limited to these two examples; any other electricity services are conceivable, and are included in the provided service information with their respective assigned electricity service IDs.

[0025] FIG. 11 is a diagram showing the data structure of participation information according to an embodiment. Each consumer may manage the electricity service they use in the form of participation information. The participation information is acquired by a participation information acquisition unit (not shown) and is used when generating a control command in the control unit 17. As shown in the figure, the participation information links the electricity service ID and each consumer's use of the electricity service to an opt-in consumer indicated by a consumer ID, and each consumer's non-use of the electricity service to an opt-out consumer indicated by a consumer ID. Although FIG. 11 manages both opt-in consumers and opt-out consumers, it is also possible to manage only one of them. Furthermore, consumers who do not receive the corresponding electricity service may be permanently managed as opt-out consumers.

[0026] The command value acquisition unit 15 is a functional unit that acquires control commands received from the electric utility 91 or the electricity-related market 92 via the first management server 80. That is, the command value acquisition unit 15 acquires control commands linked to the services included in the provided service information.

[0027] The unit price information acquisition unit 16 is a functional unit that acquires unit price information indicating the purchase price of received power from the grid power source and the sale price of discharged power to the grid power source, as indicated in the details of the contract between each consumer and the electric power company. FIG. 12 is a diagram showing the data configuration of unit price information according to an embodiment. As shown in the figure, the unit price information links the consumer ID, the basic fee in the contract, the purchase price in the contract, and the sale price in the contract. By using the unit price information, it is possible to generate a control command taking into account the purchase price and sale price of each consumer as necessary.

[0028] The control unit 17 uses the acquired device information, connection configuration information, control function layout information, provided service information, participation availability information, and unit price information to perform calculations necessary to realize the acquired command values, and generates control commands for the consumer-side energy resources 62 of each consumer. Any existing calculation method, such as mathematical programming, can be applied as a method for generating control commands from command values. The control unit 17 then outputs the generated control commands to the output unit 18. Note that the control unit 17 can generate control commands if it has at least the control function layout information, provided service information, and device information. Therefore, components other than the device information acquisition unit 11, control function layout information acquisition unit 13, provided service information acquisition unit 14, and control unit 17 are not essential for the second management server 10.

[0029] The output unit 18 outputs the generated control command to a necessary component so that the customer-side energy resource 62 is controlled in accordance with the command.

[0030] As shown in Fig. 6, the management controller 61 is one of the multiple management controllers 61 shown in Fig. 2. Note that in connection configuration C shown in Fig. 6, there is no management controller 61, but the energy management server 70 has the functions of the management controller 61. The management controller 61 includes a device information acquisition unit 611, a control command value acquisition unit 612, a weather information acquisition unit 613, a unit price information acquisition unit 614, a control unit 615, and an output unit 616. The management controller 61 can fulfill each of the above functions by executing a predetermined program using a processor and memory.

[0031] The device information acquisition unit 611 is a functional unit that acquires device information.

[0032] The control command value acquisition unit 612 is a functional unit that acquires a control command (or a control command value indicating a specific control amount, etc.).

[0033] The weather information acquisition unit 613 is a functional unit that acquires weather information (weather forecasts, etc.) related to the weather at the location of the facility where the consumer-side energy resource 62 is installed. The weather information affects, for example, the power generation efficiency of the power generation equipment and the operating efficiency of the air conditioner, which is a consumer equipment, and is therefore used to update the control amount indicated in the control command value.

[0034] The unit price information acquisition unit 614 is a functional unit that acquires unit price information.

[0035] The control unit 615 determines whether or not the control command value needs to be updated, and if updating is not necessary, outputs the control command value to the output unit 616 so that it is output to the consumer-side energy resource 62.

[0036] The output unit 616 outputs the control command value to a necessary component so that the consumer-side energy resource 62 is controlled accordingly. The output unit 616 also outputs the acquired device information to the second management server 10 via the energy management server 70 or directly.

[0037] [Example of operation] The energy resource management system configured as described above operates as follows. Fig. 13 is a flowchart showing an example of the operation of the energy resource management system according to the embodiment. As shown in Fig. 13, when the operation of the energy resource management system is started, the connection mode information acquisition unit 12 acquires connection mode information (S11). The acquired connection mode information is stored in a storage unit (not shown) or the like and used continuously, but, for example, new connection mode information may be acquired every time the command value acquisition unit 15 acquires a command, and the newly acquired connection mode information may be used each time.

[0038] Next, the control function layout information acquisition unit 13 acquires the control function layout information (S12). The acquired control function layout information is stored in a storage unit (not shown) or the like and used continuously, but for example, the command value acquisition unit 15 may acquire new control function layout information each time it acquires a command, and the newly acquired control function layout information may be used each time.

[0039] Next, the provided service information acquisition unit 14 acquires the provided service information (S13). The acquired provided service information is stored in a storage unit (not shown) or the like and is continuously used, but for example, the command value acquisition unit 15 may acquire new provided service information every time it acquires a command, and the newly acquired provided service information may be used each time.

[0040] Then, using this acquired information, the control unit 17 generates a control command.

[0041] Specifically, the control unit 17 determines whether the control function arrangement is an arrangement in which a control command should be issued under the first control (S14), and if it is determined that the arrangement is an arrangement in which a control command should be issued under the first control (Yes in S14), the control unit 17 generates a control command under the first control (S20).

[0042] If it is determined that the arrangement is not one in which a control command should be issued under the first control (No in S14), the control unit 17 determines whether the control function arrangement is one in which a control command should be issued under the second control (S15), and if it is determined that the arrangement is one in which a control command should be issued under the second control (Yes in S15), the control unit 17 generates a control command under the second control (S30).

[0043] If it is determined that the arrangement is not one in which a control command should be issued under the second control (No in S15), the control unit 17 determines whether the control function arrangement is one in which a control command should be issued under the third control (S16), and if it is determined that the arrangement is one in which a control command should be issued under the third control (Yes in S16), the control unit 17 generates a control command under the third control (S40).

[0044] When it is determined that the arrangement does not require a control command in the third control (No in S16), the control unit 17 ends the process without generating a control command.

[0045] Fig. 14 is a flowchart showing an example of the operation of the first control according to the embodiment. That is, Fig. 14 is a subflow of step S20 shown in Fig. 13. Here, generation of a control command for case 1 shown in Fig. 4 will be described as the first control. As shown in Fig. 14, first, in the second management server 10, the unit price information acquisition unit 16 acquires unit price information (S21). The acquired unit price information is stored in a storage unit (not shown) or the like and used continuously, but, for example, new unit price information may be acquired each time the command value acquisition unit 15 acquires a command, and the newly acquired unit price information may be used each time.

[0046] Next, the command value acquisition unit 15 acquires the command value (S22), and the device information acquisition unit 11 acquires the device information (S23).

[0047] The control unit 17 generates a control command (S24) and outputs it to the output unit 18. In case 1 shown in FIG. 4, the second management server 10 generates control commands for all power services, so regardless of the connection topology shown in FIG. 2, the control unit 17 calculates control commands for one or more consumer-side energy resources 62 shown in FIG. 2. When the service provided in the current slot that includes the current time (for example, when the current time is 12:00, the slot is from 12:00 to 12:30), which is the slot including the current time, is peak shaving, the control unit 17 collects information on the received power and devices of the consumers who provide the service, i.e., Opt-in consumers, and generates a control command for the consumer-side energy resources 62 so that the received power does not exceed an upper limit. When the service provided in the current slot is a downward demand response (DR) and peak shaving to reduce procurement costs, the control unit 17 collects information on the received power and devices of the Opt-in consumers and generates a control command for the consumer-side energy resources 62 so that both the downward demand response and peak shaving are achieved. The control unit 17 may generate control commands for both services simultaneously, or may generate them one by one. The control command calculated by the control unit 17 may be a command for the current slot, a command for the next slot (for example, if the current time is 12:00, a slot from 12:30 to 13:00), or a command for the next 24-hour slot (00:00 to 24:00), and there is no limit to the time period or duration that the control command applies to. The length of one slot may be 30 minutes, or may be 1 hour, etc. The output unit 18 outputs the generated control command (S25).

[0048] Fig. 15 is a communication sequence diagram showing information transmitted and received during the operation of the energy resource management system according to the embodiment. Fig. 15 is a diagram showing the overall operation of the energy resource management system in the case of the first control, taking the above into consideration. In Fig. 15, the electric utility 91 and the electric power-related market 92 are collectively referred to as the electric utility / electric power-related market 99, and the energy management server 70 and the management controller 61 are collectively referred to as the energy management server / management controller 79.

[0049] 15, the energy management server / management controller 79 transmits connection mode information, control function arrangement information, and provided service information to the second management server 10. On the other hand, the first management server 80 transmits the provided service information to the second management server 10.

[0050] Furthermore, the energy management server / management controller 79 transmits participation possibility information to the second management server 10. From the information transmitted and received up to this point, the second management server 10 can determine which of the first to third control based on the control function arrangement should be used to generate a control command.

[0051] Here, the electric utility / electricity-related market 99 transmits a command value to the first management server 80. The first management server 80 transmits the command value as is to the second management server 10 (case B shown in FIG. 3). Note that, if there are multiple second management servers 10, the first management server 80 may distribute the command value from the electric utility / electricity-related market 99 to the second management servers 10 (case A shown in FIG. 3).

[0052] On the other hand, the consumer-side energy resource 62 transmits the device information to the energy management server / management controller 79. The energy management server / management controller 79 transmits the device information to the second management server 10 as is.

[0053] Then, the second management server 10 transmits the control command value to the energy management server / management controller 79. The energy management server / management controller 79 transmits the control command value to the consumer-side energy resource 62 as is.

[0054] Fig. 16 is a flowchart showing an example of the operation of the second control according to the embodiment. That is, Fig. 16 is a subflow of step S30 shown in Fig. 13. Here, as the second control, generation of a control command for case 6 shown in Fig. 4 will be described. As shown in Fig. 16, first, in the second management server 10, the unit price information acquisition unit 16 acquires unit price information (S31). The acquired unit price information is stored in a storage unit (not shown) or the like and used continuously, but, for example, new unit price information may be acquired each time the command value acquisition unit 15 acquires a command, and the newly acquired unit price information may be used each time.

[0055] Next, the command value acquisition unit 15 acquires the command value (S32).

[0056] The control unit 17 generates a control command (S33) and outputs it to the output unit 18. For example, in case 6 shown in Fig. 4, when the management controller 61 of the connection configuration B generates a control command for a demand shift service based on the electricity rate unit price (for example, TOU (Time Of Use)) and the second management server 10 generates a control command for a downward DR to reduce procurement costs, the control unit 17 first generates the control command for the downward DR to reduce procurement costs, and the output unit 18 outputs the generated control command (S34). That is, the output unit 18 sends the control command to the management controller 61 via the energy management server 70 (in case 6, the energy management server 70 does not have a control function, so the energy management server 70 sends the control command as is to the management controller 61). The control command calculated by the control unit 17 or management controller 61 may be a command for the current slot, a command for the next slot (for example, if the current time is 12:00, the slot from 12:30 to 13:00), or a command for the next 24-hour slot (00:00 to 24:00), and there is no limit to the time period or duration that the control command applies to. Also, the length of one slot may be 30 minutes, 1 hour, etc.

[0057] In addition, the management controller 61 may first generate a control command for a demand shift service based on the electricity rate unit price, and then the control unit 17 may generate a control command for downward DR to reduce procurement costs, and there is no restriction on the order of calculation.

[0058] Meanwhile, the control unit 17 acquires an operation plan for the output control command (S35), and the device information acquisition unit 11 acquires device information (S36).

[0059] The control unit 17 updates and regenerates the control command (S37) and outputs it to the output unit 18. The output unit 18 outputs the generated control command (S38). Thereafter, the control unit 17 acquires an updated operation plan for the output updated control command (S39).

[0060] Fig. 17 is a communication sequence diagram showing information transmitted and received during the operation of the energy resource management system according to the embodiment. Fig. 17 is a diagram showing the overall operation of the energy resource management system in the case of the second control, taking the above into consideration. In Fig. 17, the electric utility 91 and the electric power-related market 92 are collectively referred to as the electric utility / electric power-related market 99, and the energy management server 70 and the management controller 61 are collectively referred to as the energy management server / management controller 79.

[0061] 17, the energy management server / management controller 79 transmits connection mode information, control function arrangement information, and provided service information to the second management server 10. On the other hand, the first management server 80 transmits the provided service information to the second management server 10.

[0062] Furthermore, the energy management server / management controller 79 transmits participation possibility information to the second management server 10. From the information transmitted and received up to this point, the second management server 10 can determine which of the first to third control based on the control function arrangement should be used to generate a control command.

[0063] Here, the electric utility / electricity-related market 99 transmits the command value to the first management server 80. The first management server 80 transmits the command value to the second management server 10 as is.

[0064] The second management server 10 transmits a control command value to the energy management server / management controller 79. The energy management server / management controller 79 transmits an operation plan corresponding to the control command to the second management server 10. In addition, the energy management server / management controller 79 transmits the control command value as is to the consumer-side energy resource 62.

[0065] On the other hand, the consumer-side energy resource 62 transmits the device information to the energy management server / management controller 79. The energy management server / management controller 79 transmits the device information to the second management server 10 as is.

[0066] Then, the second management server 10 transmits the updated control command value to the energy management server / management controller 79. The energy management server / management controller 79 transmits an operation plan for the updated control command to the second management server 10. The energy management server / management controller 79 transmits the updated control command value as is to the consumer-side energy resource 62.

[0067] The operation of the third control is not usually performed, so a description thereof will be omitted.

[0068] As described above in the embodiment, in the present invention, the second management server 10 generates a control command using control function layout information, provided service information, and device information, thereby determining the layout of the control functions and implementing appropriate control. In other words, the second management server 10 can autonomously generate a control command to control the consumer-side energy resources 62. In this way, the present invention makes it possible to more easily control the consumer-side energy resources 62. Furthermore, since it does not involve complicated operations such as processing of command values ​​by the electric utility company 91, the electricity-related market 92, or the first management server, it has the advantage of being highly compatible with existing energy resource management systems and easy to introduce.

[0069] [Variations] A modification of the above-described embodiment will be described below with reference to FIG. 18. In the modification described below, differences from the above-described embodiment will be mainly described, and descriptions of points substantially similar to the embodiment will be omitted. FIG. 18 is a diagram for explaining the connection between the components surrounding the energy resource management system according to the modification of the embodiment. FIG. 18 differs from FIG. 2 in that a management server 10A is provided instead of the first management server 80 and the second management server 10. In other words, the management server 10A is a single server that integrates the functions of the first management server 80 and the second management server 10. As described above, the management server described in the embodiment as having a two-tier configuration is not limited to the number of tiers, and may be a one-tier configuration. Furthermore, as described in FIG. 2, the management server is realized by combining servers of providers of the AC, RA, and control PFer. Therefore, the management server may be realized in a three-tier or more tier configuration, divided into an AC provider server, an RA provider server, and a control PFer provider server.
