Description

[Technical Field]

[0001] The present disclosure is an invention relating to an apparatus, a system, and a method for supporting the management of energy supply and demand. [Background technology]

[0002] In recent years, there has been a demand for efficient energy management with the aim of improving economic efficiency and reducing greenhouse gas emissions, and systems have been established that utilize technologies such as combining equipment that supplies different types of energy, energy trading between multiple regions, and demand response.As a result, supply and demand plans are being created that combine multiple energy sources and combine supply equipment to meet each energy demand, aiming to minimize costs and reduce CO2 emissions.

[0003] The supply and demand plans created for multiple energy sources such as electricity, heat, and steam aim to improve the balance between energy supply and demand and to improve income and expenditure, but the equipment that consumes or generates each energy source and its characteristics vary. Each piece of equipment is operated according to a pre-created operation plan, but errors are likely to occur in actual operation due to factors such as changes in demand and equipment failure.

[0004] In Patent Document 1, the error from the predicted value is absorbed by adjusting the output of the storage battery or gas engine. Specifically, in response to the difference between the predicted value input in "Specify predicted value" and the value during operation input in "Input current value," the difference between the predicted value and the operating value is adjusted by "Perform optimization calculation" to charge and discharge the storage battery or adjust the output of the gas engine, thereby avoiding imbalance settlement. In other words, in the prior example, in order to absorb the error from the prediction, the storage battery or gas engine is operated with adjustment capabilities.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Embodiment 1 1 is a schematic diagram showing the configuration of an energy supply and demand operation support system according to a first embodiment of the present disclosure. As shown in FIG. 1, the energy supply and demand operation system 1000 includes a data storage unit 18 and an energy supply and demand operation device 1001. The data storage unit 18 stores advance information data 15, operation status data 16, and transition plan data 17. The energy supply and demand operation support device 1001 includes a advance information acquisition processing unit 1, an operation status update processing unit 2, a status change analysis processing unit 3, a transition plan selection processing unit 4, and a plan output processing unit 5.

[0014] The advance information acquisition processing unit 1 acquires advance information data 15 from the data storage unit 18. The advance information data 15 includes, for example, equipment information data 11 indicating information on the operating conditions of a plurality of equipment (hereinafter referred to as "equipment") that supplies different types of energy, forecast information data 12 indicating a forecast value of energy demand, operation plan data 13 indicating a planned value of energy supply to the equipment, and scenario data 14 indicating a plurality of scenarios that combine the equipment information data 11, the forecast information data 12, and the operation plan data 13.

[0015] The operational status update processing unit 2 updates the operational status data 16 that indicates actual or planned values ​​of the current energy supply and energy demand.

[0016] The situation change analysis processing unit 3 creates situation change information data 19 indicating the difference between the scenario data 14 acquired by the advance information acquisition processing unit 1 and the operational situation data 16 acquired by the operational situation update processing unit 2 .

[0017] Based on the status change information data 19, the migration plan selection processing unit 4 selects scenario data 14 that meets the operating conditions of the equipment and has a small difference from the operating status data 16, and selects the operating plan data 13 corresponding to the scenario data 14 as the migration plan data 17.

[0018] The plan output processing unit 5 outputs the migration plan data 17. The migration plan data 17 is stored in the data storage unit 18.

[0019] FIG. 2 is a schematic diagram illustrating a hardware configuration of the energy supply and demand operation support system according to the first embodiment of the present disclosure. The computer 22 includes, for example, a CPU (Central Processing Unit) 23, a main storage device 24, and an auxiliary storage device 25. For example, the main storage device 24 may be a RAM, and the auxiliary storage device 25 may be a ROM or other storage medium. An input device 21 and an output device 28 are provided outside the computer 22. The input device 21 may be, for example, a mouse or a keyboard. The output device 28 may be, for example, a display monitor that displays output results from the computer 22. As shown in FIG. 2, the computer 22 is connected to an external storage device 27 via a network 26 and acquires information required for calculations from an external storage medium. The computer 22 may also be configured to store calculation results in an external storage medium.

[0020] The data storage unit 18 is for storing preliminary information data 15, operational status data 16, and migration plan data 17, and is realized, for example, by one or a combination of a main memory device 24, an auxiliary memory device 25, a network 26, and an external memory device 27.

[0021] The advance information acquisition processing unit 1, the operation status update processing unit 2, the status change analysis processing unit 3, the migration plan selection processing unit 4, and the plan output processing unit 5 (hereinafter referred to as "processing units, etc.") are realized by the CPU 23 and the main storage device 24 as internal arithmetic processing units of the computer 22. That is, each process in the processing units, etc. is realized by the CPU 23, which is a processor, executing a program deployed on the main storage device 24, which is memory. The CPU 23 reads data on the main storage device 24, performs each process, and stores the results in the main storage device 24.

[0022] 3 is a flowchart showing a method for outputting transition plan data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. Hereinafter, with reference to FIG. 3, an energy supply and demand operation support method for outputting a transition plan using the energy supply and demand operation support device will be described.

[0023] First, in step S1, the prior information acquisition processing unit 1 executes a prior information acquisition process. In this process, the prior information acquisition processing unit 1 reads prior information data 15. Here, the prior information data 15 read by the prior information acquisition processing unit 1 may be prior information data 15 input from the input device 21, or may be prior information data 15 designated by the input device 21 from among prior information data 15 stored on the auxiliary storage device 25 (e.g., electronic files stored in CSV format), or may be prior information data 15 designated by the input device 21 from among prior information data 15 stored in the external storage device 27 (e.g., electronic files stored in CSV format). The prior information acquisition processing unit 1 can read the prior information data 15 stored in the external storage device 27 via the network 26. The prior information data 15 read by the prior information acquisition processing unit 1 is expanded on the main storage device 24.

[0024] The advance information data 15 acquired by the advance information acquisition processing unit 1 in the advance information acquisition process includes device information data 11. FIG. 4 is a table illustrating an example of device information data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. The device information data 11 is device information for which the energy supply and demand operation support device 1001 creates an operation plan. As shown in FIG. 4, the device information data 11 includes the name of the device, the type of energy supplied by the device (hereinafter referred to as "supplied energy"), the maximum and minimum values ​​of the amount of energy supplied by the device, the type of energy consumed by the device (hereinafter referred to as "consumed energy"), characteristics representing the amount of energy consumed by the device to supply energy (hereinafter referred to as "consumption characteristics"), etc.

[0025] The consumption characteristics may be expressed by a fixed value or a polynomial. For example, the consumption characteristics may be expressed by a relational expression between supplied energy and consumed energy, such as the following equation (1). Equation (1) expresses supplied energy as a linear expression of consumed energy.

number

[0026] In equation (1), i represents the individual number of the equipment, t represents time, x and y represent energy identification numbers, EneOut represents supplied energy, EneIn represents consumed energy, and a represents a coefficient used in the calculation. x is used to identify the type of supplied energy when there are multiple types, and y is used to identify the type of consumed energy when there are multiple types. In equation (1), the consumption characteristics are expressed as a linear expression, but the consumption characteristics may also be expressed as a quadratic expression or a polynomial expression, and may include multiple consumed energies. The consumed energy may be fuel or supplied energy generated by other equipment, and the coefficient may vary depending on its calorific value, quality, state, or temperature.

[0027] The device information data 11 may also include information about the operating conditions of the device, such as the time required for the device to start from a stopped state and the continuous operating time required during operation.

[0028] The advance information data 15 acquired by the advance information acquisition processing unit 1 in the advance information acquisition process includes forecast information data 12. FIG. 5 is a table showing an example of forecast information data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. The forecast information data 12 is a forecast value of energy demand. As shown in FIG. 5, the forecast information data 13 includes a forecast value of electricity demand, a forecast value of heat demand, and a forecast value of steam demand. These are forecast values ​​of energy demand for each energy type and for each unit time. The vertical direction of the table is arranged in chronological order for each unit time, and the unit time may be, for example, one hour, 30 minutes, or 5 minutes, or may be a variable length of time.

[0029] The advance information data 15 acquired by the advance information acquisition processing unit 1 in the advance information acquisition process includes operation plan data 13. FIG. 6 is a table illustrating an example of operation plan data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. The operation plan data 13 is a planned value of energy supply for equipment. As shown in FIG. 6, the operation plan data 13 includes a gas turbine power supply plan value, a power purchase plan value, a boiler steam supply plan value, and a chiller heat supply plan value. The gas turbine power supply plan value and the boiler steam supply plan value are operation information of equipment planned for each equipment and for each unit time, and are planned values ​​of the energy supply amount when the equipment is stopped or when the equipment is operating. The operation information of the equipment may include a value of energy consumption during operation, or a value of CO2 emissions during operation.

[0030] The advance information data 15 acquired by the advance information acquisition processing unit 1 in the advance information acquisition process includes scenario data 14. FIG. 7 is a table showing an example of scenario data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. The scenario data 14 is a plurality of scenarios for equipment operation that combine the equipment information data 11, the forecast information data 12, and the operation plan data 13. As shown in FIG. 7, for example, the scenario data 14 includes a combination of a scenario name, the equipment constituting the equipment information, the forecast information, the operation information, and an application flag. If there is a scenario currently being used in the scenario data 14, the application flag is set to 1.

[0031] Next, in step S2 of FIG. 3 , the operation status update processing unit 2 executes an operation status update process to update the operation status data 16 indicating actual or planned values ​​of the current energy supply and energy demand. In this process, the operation status update processing unit 2 reads the current or latest operation status data 16 each time the process is executed. Here, the operation status data 16 read by the operation status update processing unit 2 may be operation status data 16 input from the input device 21, or may be operation status data 16 designated by the input device 21 from among operation status data 16 stored on the auxiliary storage device 25 (e.g., electronic files stored in CSV format), or may be operation status data 16 designated by the input device 21 from among operation status data 16 stored in the external storage device 27 (e.g., electronic files stored in CSV format). The operation status update processing unit 2 can read the operation status data 16 stored in the external storage device 27 via the network 26. The operation status data 16 read by the operation status update processing unit 2 is expanded on the main storage device 24.

[0032] FIG. 8 is a table illustrating an example of operational status data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. The operational status data 16 is actual or planned values ​​of the current energy supply and energy demand. As shown in FIG. 8, the operational status data 16 includes the power demand value, heat demand value, steam demand value, gas turbine power supply value, boiler steam supply value, and chiller heat supply value, which are past actual values ​​for each energy type or each device and for each unit time, or planned values ​​if no actual values ​​exist. Whether or not the value is actual is indicated by an actual flag; if the flag is 1, the value is actual; otherwise, the value is planned. The operational status may be acquired in response to an instruction from a user of the device, or may be acquired repeatedly at regular intervals, such as every 30 minutes.

[0033] Next, in step S3 of FIG. 3, the situation change analysis processing unit 3 creates situation change information data 19, which is the difference between the scenario data 14 and the operation status data 16. FIG. 9 is a table showing an example of situation change information data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. The situation change information data 19 represents the difference between the scenario data 14 and the operation status data 16. For example, the difference between the power demand value of the forecast information data 12 included in the scenario data 14 and the power demand value of the operation status data 16 is calculated, and the increase or decrease is represented. For example, the situation change information data 19 is expressed as in equation (2).

number

[0034] In equation (2), DiffPower is the power demand in the status change information data 19, PowerCurrent is the power demand in the operation status data 16, PowerScenario is the power demand in the scenario data 14, and t is time. Equation (2) illustrates the difference in power demand at time t, and may also be an equation that represents changes in energy other than power demand, such as heat demand or steam demand. Furthermore, the status change information data 19 may include not only hourly values, but also values ​​for times ahead of the present, total values ​​for all times, etc. The status change information data 19 may also include a status change flag, which indicates 1 if a status change has occurred and indicates something else if no status change has occurred.

[0035] Next, in S4 of FIG. 3, if a situation change occurs, the migration plan selection processing unit 4 selects scenario data 14 that satisfies the operation conditions of the equipment and has a small difference from the operation situation data 16 based on the situation change information data 19, and selects the operation plan data 13 corresponding to the scenario data 14 as the migration plan data 17. If no situation change occurs, the process returns to step S2 of FIG. 3 and performs the operation situation update process. The timing of performing the operation situation update process may be based on a user instruction, or may be performed periodically at regular time intervals. In the migration plan selection process, the migration plan selection processing unit 4 refers to the situation change information, selects scenario data 14 that corresponds to the situation change, and selects the included operation plan data 13 as the migration plan data 17. One or more scenario data 14 may be selected, and one or more migration plan data 17 may be selected.

[0036] In response to a change in situation, for example, if the change in power demand at time t calculated by equation (2) indicates an increase in demand, scenario data 14 in which power purchases at time t are increased may be selected. Alternatively, scenario data 14 in which the power supply of a gas turbine is increased may be selected. When selecting transition plan data 17, the operating conditions of the equipment must be considered if the operation of the equipment is to be changed. For example, if a certain amount of time is required for the equipment to start from a stopped state, the transition plan data 17 cannot immediately start the equipment. Furthermore, if continuous operation for a certain period of time or more is required during operation, the transition plan must not immediately stop the equipment if the continuous operation time is insufficient. In other words, the transition plan selection processing unit 4 selects the transition plan data 17 by taking into consideration the correction of the energy supply and demand balance caused by the change in situation and satisfying the operating conditions of the equipment.

[0037] Next, in step S5 of Fig. 3, the plan output processing unit 5 outputs the operation plan data 13 determined to be applicable as migration plan data 17. In this process, the migration plan data 17 output by the plan output processing unit 5 is stored in the data storage unit 18. In addition, the plan output processing unit 5 may display the migration plan data on the output device 28 so that the user can check the migration plan.

[0038] 10 is a table illustrating an example of transition plan data of the energy supply and demand operation support device according to the first embodiment of the present disclosure. As shown in FIG. 10, the transition plan data 17 includes, for example, a power demand value, a heat demand value, a steam demand value, a gas turbine power supply value, a power purchase value, a boiler steam supply value, a chiller heat supply value, a transition application flag, etc. The transition application flag is a flag that indicates 1 at a time when a change has occurred from the previous operation plan data 13 in the transition plan data 17, and indicates something other than 1 if no change has occurred.

[0039] As described above, the energy supply and demand operation support device 1001 of the present disclosure includes the advance information acquisition processing unit 1, the operation status update processing unit 2, the status change analysis processing unit 3, the transition plan selection processing unit 4, and the plan output processing unit 5. The energy supply and demand operation system 1000 also includes the energy supply and demand operation support device 1001 and a data storage unit 18.

[0040] The energy supply and demand operation support device 1001, the energy supply and demand operation system 1000, and the energy supply and demand operation method select, based on the situation change information data 19, scenario data 14 that satisfies the operation conditions of the equipment and reduces the difference with the operation status data 16, and selects the operation plan data 13 corresponding to the scenario data 14 as a plan for shifting the operation of the equipment. This eliminates the need for the equipment that supplies energy to leave a surplus capacity to adjust for errors with the prediction in response to changes in the energy supply and demand situation.

[0041] Embodiment 2 In the second embodiment, the same components as those in the first embodiment of the present disclosure are designated by the same reference numerals, and descriptions of the same or corresponding parts are omitted. Hereinafter, an energy demand and supply operation support device 1002 according to the second embodiment will be described with reference to the drawings.

[0042] Fig. 11 is a schematic configuration diagram showing the configuration of an energy supply and demand operation support device according to embodiment 2 of the present disclosure. As shown in Fig. 11, an energy supply and demand operation support device 1002 includes a transition impact assessment processing unit 41 and a transition plan extraction processing unit 42 in addition to the configuration of the energy supply and demand operation support device 1001. In the following, the energy supply and demand operation support device 1002 will be described mainly with reference to the first embodiment, with the explanation of the parts that overlap with those in the first embodiment being omitted.

[0043] 12 is a flowchart showing a method for outputting transition plan data of an energy supply and demand operation support device according to the second embodiment of the present disclosure. This flowchart is obtained by adding a transition impact assessment process in step S11 and a transition plan extraction process in step S12 between the transition plan selection process in step S4 and the plan output process in step S5 to the flowchart in FIG. 3. As shown in FIG. 12, first, in step S11, the transition impact assessment processing unit 41 creates transition impact assessment data 51 based on the pre-migration operation plan data 13 and the transition plan data 17 selected by the transition plan selection processing unit 4. The transition impact assessment data 51 represents the magnitude of the impact when switching from the pre-migration operation plan to the transition plan, and is expressed, for example, by the following equation (3):

number

[0044] In equation (3), t_next is the time when the situation change occurred, t is time, x is the type of energy, i is the individual number of the equipment, β is the adjustment coefficient for each energy type, Eva_val is the evaluation value of the impact of the transition, EneOut_next is the supplied energy in the transition plan, and EneOut is the supply amount in the operation plan data 13 before the transition. Equation (3) represents the sum of squares of the difference in the supplied energy before and after the transition, and uses the magnitude of fluctuation in the supplied energy of each equipment for evaluation. The evaluation value is not limited to equation (3). For example, it may be based on differences in the shutdown status of the equipment, or on changes in the total daily energy supply amount.

[0045] Next, in step S12, when the operation plan data 13 is selected by the migration plan selection processing unit 4 and the migration impact assessment data 51 is created by the migration impact assessment processing unit 41, the migration plan extraction processing unit 42 acquires migration plan data based on the migration impact assessment data 51, and extracts migration plan data that will have a small impact when migrating the operation plan based on the migration impact assessment data 51. The processing of the migration plan extraction processing unit 42 will be described below with reference to FIG.

[0046] FIG. 13 is a flowchart showing a transition plan extraction process of an energy supply and demand operation support device according to the second embodiment of the present disclosure. In step S21, the transition plan extraction processing unit 42 acquires the transition plan data 17 selected in the transition plan selection process. In step S22, transition plan evaluation information for the transition plan is acquired. In step S23, the acquired transition plans are sorted in ascending order of evaluation value based on the transition plan evaluation information. The evaluation value represents the magnitude of the impact of migrating the operation plan, and the transition plans are arranged in ascending order of impact. In step S24, the transition plan evaluation information is selected in ascending order of evaluation value. The number of transition plans to be extracted may be one, a predetermined constant, or a fixed proportion of the transition plans selected in the transition plan selection process. Then, the transition plan data 17 selected in step S24 is output by the plan output unit 5. At this time, the transition plan with the smallest evaluation value may be output, or the transition plans may be output in ascending order of evaluation value.

[0047] In the energy supply and demand operation support device 1002, energy supply and demand operation system 1000b, and energy supply and demand operation method of this embodiment, similarly to the first embodiment, scenario data 14 that satisfies the operation conditions of the equipment and that has a small difference from the operation status data 16 is selected based on the situation change information data 19, and operation plan data 13 corresponding to the scenario data 14 is selected as a plan for shifting the operation of the equipment. With this configuration, it is no longer necessary for the equipment that supplies energy to leave a surplus capacity to adjust for errors with predictions in response to changes in the energy supply and demand situation.

[0048] Furthermore, the energy supply and demand operation support device 1002, energy supply and demand operation system 1000b, and energy supply and demand operation method of this embodiment are equipped with a transition plan evaluation processing unit 41 and a transition plan extraction processing unit 42 in addition to the configuration of embodiment 1, and are capable of extracting transition plan data that has little impact when transitioning an operation plan based on the transition impact assessment data, thereby making it possible to efficiently transition to a plan that is more responsive to changes in the operation situation.

[0049] Embodiment 3 In the third embodiment, the same components as those in the first embodiment of the present disclosure are designated by the same reference numerals, and descriptions of the same or corresponding parts are omitted. Hereinafter, the energy demand and supply operation support device 1003 according to the third embodiment will be described with reference to the drawings.

[0050] Fig. 14 is a schematic diagram showing the configuration of an energy supply and demand operation support device according to embodiment 3 of the present disclosure. As shown in Fig. 14, the energy supply and demand operation support device 1003 includes a return information acquisition unit 61 in addition to the configuration of the energy supply and demand operation support device 1001. In the following, the energy supply and demand operation support device 1003 will be described mainly with reference to the first embodiment, with the explanation of the parts that overlap with those in the first embodiment being omitted.

[0051] 15 is a flowchart showing a method for outputting transition plan data of an energy supply and demand operation support device according to the third embodiment of the present disclosure. This flowchart is obtained by adding a restoration information acquisition process in step S31 between the situation change analysis process in step S3 and the transition plan selection process in step S4 to the flowchart in FIG. 3. As shown in FIG. 15, in step S31, when the situation change information data 19 is created by the situation change analysis processing unit 3, the restoration information acquisition unit 61 acquires restoration information data 71 indicating information related to the restoration of the device that caused the situation change.

[0052] FIG. 16 is a table illustrating an example of restoration information data of an energy supply and demand operation support device according to the third embodiment of the present disclosure. In this example, restoration information data 71 includes the device and the event that caused the status change, the date and time when the event occurred and the scheduled restoration date and time, a restoration completion flag, an update date and time, etc. The restoration completion flag becomes 1 when restoration is complete and is 0 before restoration. When the restoration completion flag is 0, the restoration date and time is scheduled information. If the information is changed because the scheduled restoration date and time is changed earlier or later, the update date and time is also changed. Note that if the cause of the status change is not due to an emergency breakdown or work, there is no need to use restoration information for the status change.

[0053] Next, in step S4 of Fig. 15, the migration plan selection processing unit 4 selects the operation plan data 13 as the migration plan data 17 based on the restoration information data 71. At this time, if the cause of the situation change is resolved by the restoration information data 71, it is possible to return to the operation plan before the migration. In that case, it can be considered that the situation change occurs after the restoration date and time, and it is necessary to satisfy the operation conditions of the equipment when returning from the migration plan data 17 to the original operation plan data 13.

[0054] Fig. 17 is a table showing a transition plan that takes into account the restoration information data of the energy supply and demand operation support device according to the third embodiment of the present disclosure. As an example, Fig. 17 shows that, based on the content of the transition application flag, the transition plan is applied from time 4 due to a change in the situation, application of the transition plan is terminated at time 8, and the original operation plan is restored from time 9. In step S5 of Fig. 15, the transition plan data 17 and operation plan data 13 selected in step S4 are output by the plan output unit 5.

[0055] In the energy supply and demand operation support device 1003, the energy supply and demand operation system 100c, and the energy supply and demand operation method of this embodiment, similarly to the first embodiment, scenario data 14 that satisfies the operation conditions of the equipment and that has a small difference from the operation status data 16 is selected based on the situation change information data 19, and operation plan data 13 corresponding to the scenario data 14 is selected as a plan for shifting the operation of the equipment. With this configuration, it is not necessary for the equipment that supplies energy to leave a surplus capacity to adjust for errors with the prediction in response to changes in the energy supply and demand situation.

[0056] Furthermore, the energy supply and demand operation support device 1003, energy supply and demand operation system 1000c, and energy supply and demand operation method of the present embodiment include, in addition to the configuration of embodiment 1, a return information acquisition unit 61 that acquires return information data 71, which is information indicating the cause of a situation change, and the transition plan selection processing unit 4 selects operation plan data 13 based on the return information data 71. By including the return information acquisition processing unit 61, it is possible to acquire return information of the device that caused the situation change, and to select a transition plan corresponding to the return information in the subsequent transition plan selection processing of the transition plan selection processing unit 4. Therefore, the energy supply and demand operation device 1003 can use a transition plan that is less affected by transition, taking into account the return information of the device from the return information data 71.

[0057] Embodiment 4 In the fourth embodiment, the same components as those in the first embodiment of the present disclosure are designated by the same reference numerals, and descriptions of the same or corresponding parts will be omitted. Hereinafter, the energy demand and supply operation support device 1004 according to the fourth embodiment will be described with reference to the drawings.

[0058] 18 is a schematic configuration diagram showing the configuration of an energy supply and demand operation support device according to embodiment 4 of the present disclosure. In addition to the configuration of the energy supply and demand operation support device 1001, the energy supply and demand operation support device 1004 includes a scenario creation processing unit 81 and past performance information data 91. In the following, the energy supply and demand operation support device 1004 will be described mainly with reference to the first embodiment, with the explanation of the parts that overlap with the first embodiment being omitted.

[0059] The scenario creation processing unit 81 acquires past performance information data 91, which is performance values ​​of the operation of the equipment, from the prior information acquisition unit 1, and creates scenario data 14 including a scenario for the operation of the equipment based on the past performance information data 91. The past performance information data 91 includes at least performance values ​​of the energy supply and energy demand of the equipment in the past.

[0060] 19 is a flowchart showing a method for outputting transition plan data of an energy supply and demand operation support device according to embodiment 4 of the present disclosure. As shown in Fig. 19, this flowchart is obtained by adding a scenario creation process in step S31 between the advance information acquisition process in step S1 and the operation status update process in step S2 to the flowchart in Fig. 3.

[0061] In step S31, the scenario creation processing unit 81 executes a scenario creation process, acquires past performance information data 91, and creates scenario data 14. Specifically, for example, past performance information data corresponds to performance values ​​for which performance flags are set among the operational status data acquired in the past. This information corresponds to the information contained in the scenario data 14, and performance values ​​of various demands can be used instead of forecast information, and operational performance of each device can be used instead of an operational plan. The scenario creation processing unit 81 can create scenario data 14 based on this information.

[0062] In step S4, the migration plan selection processing unit 4 executes migration plan selection processing. In this processing, the scenario data 14 created by the scenario creation processing unit 81 and the situation change information data 19 created by the situation change analysis processing unit 3 are read, and migration plan data 17 is selected. In step S5, the plan output unit 5 outputs the migration plan data 17 selected in step S4.

[0063] As in the first embodiment, the energy supply and demand operation support device 1004, the energy supply and demand operation system 1000d, and the energy supply and demand operation method of this embodiment select, based on the situation change information data 19, scenario data 14 that satisfies the operation conditions of the equipment and reduces the difference with the operation status data 16, and selects the operation plan data 13 corresponding to the scenario data 14 as a plan for shifting the operation of the equipment. With this configuration, it is not necessary for the equipment that supplies energy to leave a surplus capacity to adjust for errors with predictions in response to changes in the energy supply and demand situation.

[0064] Furthermore, the energy supply and demand operation support device 1004, energy supply and demand operation system 1000d, and energy supply and demand operation method of the present embodiment include, in addition to the configuration of the first embodiment, a scenario creation processing unit 81 that acquires past performance information data 91 indicating past performance values ​​of energy supply and energy demand of devices from the prior information acquisition unit 1, and creates scenario data 14 including a scenario for operation of the devices based on the past performance information data 91. The scenario creation processing unit 81 acquires the past performance information data 91 and creates scenario data 14 based on the performance values ​​of demand for various types of energy and the performance values ​​of energy supply for each device. The transition plan selection processing unit 4 selects transition plan data 17 from the currently applied operation plan data 13 using the scenario data 14 created by the scenario creation processing unit 81 and the situation change information data 19 created by the situation analysis processing unit 3. Therefore, according to the energy supply and demand management device 1004, by utilizing the past performance information data 91, there is no need to prepare in advance forecast information data 12 and operation plan data 13 that can be used as transition plan data 17, and scenario data 14 created from the past performance information data 91 can be used, thereby reducing the burden of creating a scenario from the advance information data 15.

Furthermore, parts of the configurations may be omitted or modified without departing from the scope of the present disclosure. [Explanation of symbols]
