Description

[Technical Field]

[0001] The present embodiment relates to an information processing device, an information processing method, a computer program, and an information processing system. [Background technology]

[0002] In recent years, renewable hydrogen systems have been attracting attention as an energy system that utilizes renewable energy as a measure to reduce CO2 emissions and as a business continuity plan (BCP) measure in the event of a disaster. A commonly used control method for renewable hydrogen systems is a control method (hysteresis band method) that combines storage batteries to maximize self-consumption of renewable energy. A specific example is a method that controls hydrogen storage devices and power generation devices within the consumer's facility, taking into account the cost of electricity.

[0003] As economic rationality is required for renewable hydrogen systems in the future, it is expected that operation will increasingly be based on a long-term perspective. Requirements for renewable hydrogen systems will include direct supply of hydrogen, increased utilization of renewable energy, net-zero power supply, and reduction of peak grid power. Creating a plan that meets these requirements may enable efficient operation of energy systems that are economically rational. [Prior art documents] [Patent documents]

[0008] Hereinafter, the present embodiment will be described with reference to the drawings. In each drawing, elements having the same or equivalent functions are denoted by the same reference numerals, and detailed descriptions thereof will be omitted as appropriate, except for expanded or modified processes.

[0009] (First embodiment) 1 is a block diagram showing the overall configuration of an information processing system 1 according to the first embodiment. The information processing system 1 includes an energy system 200, an operation plan creation device 10 that creates an operation plan for the energy system 200, and a control device 400 that controls the energy system 200 based on the operation plan. The operation plan creation device 10, or a combination of the operation plan creation device 10 and the control device 400 (control unit), corresponds to the information processing device according to this embodiment.

[0010] The energy system 200 includes components such as a renewable energy hydrogen system 100, a solar power generation device 500, an electricity consumer (load) 300, and a load device 900. The renewable energy hydrogen system 100 is capable of receiving and transmitting (reverse flow) electricity to and from a power line (bus) 700, and is connected to an electric power grid 800 via the power line (bus) 700. Receiving electricity from the electric power grid 800 is equivalent to purchasing electricity, and transmitting electricity to the electric power grid 800 is equivalent to selling electricity.

[0011] In addition to the renewable hydrogen system 100, a solar power generation device 500, a power consumer 300, a load device 900, and the like are connected to the power line 700. The power consumer 300 corresponds to an example of a load (power consumption device) that consumes power. The load device 900 is also an example of a power consumption device, and the load device 900 may be, for example, a device such as a motor, or any power consumption device within a facility. The solar power generation device 500 is a device that converts solar light energy, which is an environmental condition, into electricity and outputs the converted electricity to the power line 700. In the example of FIG. 1, one solar power generation device 500, one power consumer 300, and one load device 900 are shown, but multiple solar power generation devices may be present. Furthermore, a wind power generation device other than a solar power generation device may be connected to the power line 700 as a natural energy power generation device. A wind power generation device is a device that converts wind power, which is an environmental condition, into electricity.

[0012] The renewable energy hydrogen system 100 includes a storage battery 101, a hydrogen production unit (EC) 102, a hydrogen tank 103 (storage unit), a fuel cell (FC) 104, a hydrogen supply unit 105, and a hydrogen tank 106 (storage unit).

[0013] The storage battery 101 charges and discharges power in accordance with control information (operation command values) provided by the control device 400. Charging and discharging include at least one of charging and discharging. When charging, the storage battery 101 stores surplus power. The surplus power includes, for example, power generated by the solar power generation device 500 and power received from the power grid 800 that remains unused by the power consumer 300, the load device 900, the hydrogen production device 102, etc. When discharging, the storage battery 101 discharges the power stored therein to the power line 700. The discharged power can be consumed by the power consumer 300, the load device 900, the hydrogen production device 102, etc., or transmitted to the power grid 800.

[0014] The hydrogen production device 102 produces the demanded amount of hydrogen using power supplied from the power line 700 (which may include power received from the power grid 800) in accordance with control information provided by the control device 400. The hydrogen production device 102 is also an example of a power consumption device that consumes power. The hydrogen production device 102 sends the produced hydrogen to at least one of the hydrogen tank 103 and the hydrogen tank 106. The hydrogen production device 102 produces hydrogen using power, for example, by electrolysis, such as alkaline water electrolysis. In this embodiment, hydrogen is used as the demanded amount, but depending on the type of target (demanding device) to which the demanded amount is to be supplied, it may be a gas other than hydrogen, a liquid or solid, or an intangible entity such as electricity.

[0015] The hydrogen tank 103 is a storage device that receives and stores hydrogen for the fuel cell 104, produced by the hydrogen production device 102. The hydrogen tank 106 is a storage device that receives and stores hydrogen for the FCV, produced by the hydrogen production device 102. The hydrogen tank 103 and the hydrogen tank 106 are high-pressure hydrogen gas containers (hydrogen pressure vessels) or hydrogen storage alloy containers, etc. The hydrogen tank 103 has the function of providing stored hydrogen to the fuel cell 104 and the function of measuring the amount of stored hydrogen. The hydrogen tank 106 has the function of providing stored hydrogen to the hydrogen supply device 105 and the function of measuring the amount of stored hydrogen.

[0016] The fuel cell 104 generates electricity using hydrogen supplied from the hydrogen tank 103 and supplies the generated electricity to a power line 700. The fuel cell 104 is, for example, a solid polymer type or a solid oxide type fuel cell. Devices other than fuel cells may also be used as long as they have the function of generating electricity using hydrogen.

[0017] The hydrogen supply device 105 has the function of receiving hydrogen stored in the hydrogen tank 106 and supplying the received hydrogen to an external demand device, which is an FCV. In this embodiment, the external demand device is a hydrogen fuel cell vehicle (FCV). In this case, hydrogen can be used as fuel for the fuel cell vehicle. The external demand device is not limited to an FCV, as long as it is a device that operates using hydrogen.

[0018] The operation plan creation device 10 creates an operation plan for the energy system 200. As the operation plan, the operation plan creation device 10 creates a hydrogen production plan for storage in the hydrogen tank 106 or a storage amount plan that is a transition plan for the storage amount of hydrogen (demand amount) in the hydrogen tank 106. The operation plan creation device 10 may also create a plan (power supply and demand plan) regarding the accumulation of the amount of power transmitted and received to and from the power grid 800.

[0019] In this embodiment, the hydrogen production plan for the FCV represents a hydrogen production plan for the short period up to the time of supplying hydrogen to the FCV. The production plan can be represented, for example, as a graph with time on the horizontal axis and the amount of hydrogen produced on the vertical axis. A hydrogen storage amount plan for the hydrogen tank 106 may be created instead of, or in addition to, the production plan. The hydrogen storage amount plan represents the progress of the amount of hydrogen stored (remaining amount) when hydrogen produced according to the production plan is stored in the hydrogen tank 106 and hydrogen supplied from the hydrogen tank 106 to the FCV is output from the hydrogen tank 106 (see Figures 4A and 9).

[0020] In this embodiment, the power supply and demand plan represents a plan for the cumulative amount of power with the power grid 800 over a short period up to the time of hydrogen supply to the FCV. The power supply and demand plan can be represented, for example, as a graph with time on the horizontal axis and the cumulative amount of power transmitted and received between the power grid 800 and the power grid 800 on the vertical axis. A cumulative amount of power of 0 or less means that power is not actually received from the power grid 800 and power generated by the energy system 200 is sufficient (Netzero).

[0021] The control device 400 collects operation data of each device in the energy system 200 . The operation data of the storage battery 101 includes, for example, a history of changes in the amount of power stored in the storage battery 101 or a history of charging and discharging (time and amount of power charged and discharged, etc.). The operational data of the hydrogen production device 102 includes, for example, the amount of power used in hydrogen production and the hydrogen production history (time, amount of hydrogen produced, etc.). The operational data of the fuel cell 104 includes, for example, a history of power generation (time, amount of power generated, etc.), and may further include the amount of hydrogen used for power generation. The operational data of the hydrogen tank 103 includes, for example, a history of the amount of hydrogen stored (time, amount of hydrogen, etc.). The operational data of the hydrogen tank 106 includes, for example, the history of the amount of hydrogen stored (time, amount of hydrogen, etc.). The operational data of the hydrogen supply device 105 includes, for example, the history (time, amount of hydrogen, etc.) of hydrogen provided to an external demand device (FCV). The operational data of the solar power generation device 500 includes, for example, a history of power generation (time, amount of power generation, etc.). The operation data of the power consumer 300 includes, for example, a history of power consumption (time, power consumption, etc.). The operation data of the power system 800 includes a history of the amount of power transmitted to and received from the power system 800 (time, amount of power transmitted and received, etc.).

[0022] The control device 400 controls the renewable energy hydrogen system 100 or the energy system 200 based on the collected operation data so as to fulfill the operation plan (hydrogen production plan / hydrogen storage amount plan, power supply and demand plan, etc.). The devices in the energy system 200 control the storage battery 101, the hydrogen production device 102, and the fuel cell 104. The devices in the energy system 200 include the storage battery 101, the hydrogen production device 102, the hydrogen tank 103, the fuel cell 104, the hydrogen supply device 105, the hydrogen tank 106, the power consumer 300, the solar power generation device 500, and the load device 900. As an example of controlling the renewable energy hydrogen system 100 or the energy system 200, the control device 400 controls the power generation of the fuel cell 104, the production of hydrogen by the hydrogen production device 102 for storage in the hydrogen tank 106, the production of hydrogen by the hydrogen production device 102 for storage in the hydrogen tank 103, the charging of the storage battery 101, the discharging of the storage battery 101, the sale of electricity to the power grid 800, the purchase of electricity from the power grid 800, etc.

[0023] The operation plan creation device 10 of this embodiment creates an operation plan (e.g., a hydrogen production plan / hydrogen storage plan, or power supply and demand plan) for controlling the renewable energy hydrogen system 100 or the energy system 200 as a plan that enables economically efficient operation.

[0024] 2 is a block diagram of an example of the operation plan creation device 10. The operation plan creation device 10 creates an operation plan using weather forecast data.

[0025] The operation plan creation device 10 includes a weather forecast data acquisition unit 11, a demand forecast data acquisition unit 12, an operation data acquisition unit 13, an operation plan creation unit 14 (plan creation unit), and an operation plan data storage unit 15. The weather forecast data acquisition unit 11 is connected to a weather forecast server 91 via a communication network 90. ​​The demand forecast data acquisition unit 12 is connected to a demand forecast management server 92 via the communication network.

[0026] The weather forecast data acquisition unit 11 communicates with a weather forecast server 91 via a communication network 90 and acquires weather forecast data from the weather forecast server 91. The weather forecast data is an example of data relating to the environmental state of a power generation device such as the solar power generation device 500. The data relating to the environmental state is not limited to this, and may be, for example, past performance data or statistical data, or data assumed for simulation.

[0027] The demand forecast data acquisition unit 12 communicates with the demand forecast management server 92 via the communication network 90 and acquires demand forecast data from the demand forecast management server 92. The demand forecast data includes a demand forecast for the most recent short period (target period). The demand forecast data includes demand forecast data (first demand data) for hydrogen to be supplied to external devices (FCVs in this example) during the target period. The demand forecast may further include demand forecast data (second demand data) for electricity of electricity consuming devices (electricity consumers 300, load devices 900, etc.) during the target period. The hydrogen demand forecast data is an example of first demand data related to the demand amount required by the external devices during the first period. The first demand data may be, for example, past performance data or statistical data, data predicted from past performance data or statistical data, or any other data as long as it represents the demand amount. The electricity demand forecast data is an example of second demand data related to the electricity consumed during the first period. The second demand data may be, for example, past performance data or statistical data, or data predicted from past performance data or statistical data, or any other data as long as it represents the power to be consumed.

[0028] The operation data acquiring unit 13 acquires operation data (system operation data) of the energy system 200. More specifically, the operation data acquiring unit 13 communicates with each device constituting the energy system 200 and acquires operation data from each device.

[0029] The operation plan creation unit 14 creates an operation plan using weather forecast data, demand forecast data, and operation data. The period covered by the weather forecast data (forecast period) may be the same as the short-term period covered by the demand forecast data (target period), or may further include at least one period before or after the target period. The operation data may be, for example, operation data acquired when processing the operation plan creation, or a history of operation data acquired before the processing.

[0030] The operation plan data storage unit 15 stores therein the data of the operation plan created by the operation plan creation unit 14.

[0031] The control device 400 acquires operation data from the operation data acquisition unit 13 and reads out operation plan data from the operation plan data storage unit 15. The operation command value generation unit 410 identifies devices to be controlled based on the operation data and the operation plan, and generates control information to control the devices to be controlled as operation command values. The devices to be controlled include at least one of the hydrogen production device 102, the fuel cell 104, and the storage battery 101. The operation command value transmission unit 420 transmits the generated operation command value to the devices to be controlled. The devices to be controlled operate in accordance with the received operation command value.

[0032] 3 shows a flowchart of an example of processing by the operation plan creation device 10. This processing shows an example in which hydrogen demand forecast data is acquired as a demand forecast, and a production plan or storage amount plan for hydrogen to be supplied to an external demand device (in this example, an FCV) is created as an operation plan.

[0033] First, the weather forecast data acquisition unit 11 acquires weather forecast data, the demand forecast data acquisition unit 12 acquires hydrogen demand forecast data, and the operation data acquisition unit 13 acquires operation data of the energy system 200 (S101).

[0034] Next, the operation plan creation unit 14 checks the current amount of hydrogen stored in the hydrogen tank 106 based on the system operation data. The operation plan creation unit 14 checks the amount of hydrogen supply (guaranteed hydrogen supply amount) planned to be supplied from the hydrogen supply device 105 to the FCV on the scheduled hydrogen supply date (first time point) based on the hydrogen demand forecast data, i.e., the predicted hydrogen demand (S102).

[0035] If the amount of stored hydrogen is less than the guaranteed hydrogen supply amount, i.e., if the amount of stored hydrogen is insufficient (NO in S102), the operation plan creation unit 14 calculates the total hydrogen production time required for the hydrogen production device 102 to produce the shortfall of hydrogen (S103).

[0036] Meanwhile, the operation plan creation unit 14 compares the amount of solar radiation (or solar radiation intensity) for each day within the prediction period based on weather forecast data (S104). The prediction period is a fixed period prior to the timing of supplying hydrogen to the FCV (scheduled hydrogen supply date). The operation plan creation unit 14 determines the priority of the days for producing hydrogen based on the amount of solar radiation for each day (S105). For example, the hydrogen production days are determined in descending order of solar radiation.

[0037] The operation plan creation unit 14 creates a hydrogen production plan that allocates the total hydrogen production time to one or more days based on the total hydrogen production time calculated in step S103 and the priority of the hydrogen production days determined in step S105 (S106). The allocation is performed, for example, by preferentially allocating hydrogen production time to days with high solar radiation intensity until the total allocated hydrogen production time reaches the total hydrogen production time. The time period for hydrogen production within a day may be determined as a time period when the predicted solar radiation value in the weather forecast data is equal to or greater than a certain value, or the time period for hydrogen production may be determined as a predetermined time period, such as 8:00 AM to 5:00 PM. By allocating hydrogen production time to each day in this manner according to priority, a hydrogen production period is determined that includes the days on which hydrogen production time is allocated. The hydrogen production period does not need to be consecutive days, but may be multiple days spaced apart.

[0038] If the amount of hydrogen stored in the hydrogen tank 106 is equal to or greater than the guaranteed hydrogen supply amount, the operation plan creation unit 14 creates an operation plan that is a hydrogen production plan that does not produce hydrogen from today until the day before hydrogen is supplied to the FCV. When creating a hydrogen storage amount plan as an operation plan, the current hydrogen storage amount plan can be used as the operation plan as is (however, it is assumed that there are no plans to supply hydrogen from other hydrogen tanks 106 until the scheduled day of hydrogen supply to the FCV).

[0039] The operation plan creation unit 14 determines whether to continue operation (S108). For example, if there is still one or more days remaining until the day hydrogen is to be supplied to the FCV, it determines to continue operation (YES). In this case, the process returns to step S101, new weather forecast data, etc. is acquired, and an operation plan is created. The accuracy of the weather forecast also increases as the target day (scheduled hydrogen supply date) approaches, and if the content of the weather forecast data differs from the weather forecast data acquired last time, the priority of the hydrogen production day in step S105 may be changed from the previous one depending on the comparison result of the amount of solar radiation in step S104. If the operation plan creation unit 14 determines not to continue operation (NO), this process ends.

[0040] In the above explanation, the guaranteed hydrogen supply amount has been described as the amount of hydrogen that needs to be supplied to the FCV, but in order to deal with unexpected hydrogen supplies, a predetermined minimum hydrogen supply amount may be determined and that determined value may be used as the guaranteed hydrogen supply amount. In this case, the minimum hydrogen supply amount may be a value greater than the maximum amount of hydrogen that may be supplied to the FCV on the scheduled hydrogen supply day (upper limit hydrogen amount).

[0041] Furthermore, while the priority of hydrogen production dates (hydrogen production timing) was determined based solely on the amount of solar radiation for each day in weather forecast data, if power demand forecast data is used, the priority may also be determined taking into account the power demand for each day. For example, the priority may be determined in descending order of the value obtained by subtracting the power demand for each day from the amount of power generated, calculated from the amount of solar radiation for each day. In the above-described processing, the operation plan creation unit 14 acquires and uses both weather forecast data and demand forecast data, but it may acquire and use only one of them. In this case, for example, when weather forecast data is acquired but demand forecast data is not acquired, processing may be performed assuming that a certain amount of demand occurs at regular intervals, or the amount of demand may be predicted from past operation data.

[0042] FIG. 4 is a diagram showing a specific example of creating a hydrogen production plan as an operation plan in accordance with the operations shown in the flowchart of FIG.

[0043] The upper diagram in Figure 4 shows weather forecast data acquired from a weather forecast server. The weather forecast server made a weather forecast at 9:00 PM on October 5th, and the weather forecast data was updated the following day, at 7:00 AM on October 6th. The weather forecast data acquisition unit 11 acquires this updated weather forecast data. The upper diagram in Figure 4 shows this acquired weather forecast data. The weather forecast data includes the distribution of solar radiation for each day from October 6th onwards. In this example, data up to October 13th is shown, but data from the 14th onwards may also be available.

[0044] The lower diagram in Figure 4 shows an example of calculating the distribution of power generation (PV power generation) of the solar power generation device 500 from the distribution of solar radiation for each day shown in the weather forecast data for the period (6 days) before the scheduled hydrogen supply date for the FCV. The scheduled hydrogen supply date (day 7) corresponds to October 13th in the weather forecast data, and the six days (days 1 to 6) before the scheduled hydrogen supply date are the target period for the operation plan. The scheduled hydrogen supply date (day 7) may also be included in the target period. Days 1 to 6 correspond to October 7 to October 12th in the weather forecast data. The six days (days 1 to 6) within the target period are candidate dates for allocating hydrogen production time.

[0045] The operation plan creation unit 14 compares the amounts of power generated on days 1 to 6 and identifies days 1, 5, and 6 on which the amount of power generated is equal to or greater than the threshold. The operation plan creation unit 14 allocates hydrogen production time to the hydrogen production device 102 in order of the identified days, starting from the earliest day, until the allocated hydrogen production time reaches the total hydrogen production time. The hydrogen production time in one day is defined as time periods R1, R2, and R3 when the solar radiation intensity (or generated power) exceeds the threshold Th1.

[0046] The upper diagram in Figure 4A shows an example of a created hydrogen production plan. Hydrogen production times are assigned to time R1 on October 7, time R2 on October 11, and time R3 on October 12. The bottom diagram in Figure 4A shows an example of a hydrogen storage amount plan based on the created hydrogen production plan. As hydrogen is produced over three days and stored in the hydrogen tanks 106, the amount of hydrogen stored gradually increases. However, it is assumed that there are no plans to supply hydrogen from other hydrogen tanks 106 until the scheduled date for hydrogen supply to the FCV.

[0047] In the example of Figure 4, the day on which the amount of power generation in one day is equal to or greater than a threshold is set as the day on which hydrogen production time is allocated, but regardless of the amount of power generation, the priority of days 1 to 6 can be determined in descending order of power generation amount, and hydrogen production time can be allocated to the hydrogen production device on each day according to the determined priority.

[0048] In the example of FIG. 4, the time to allocate the hydrogen production time is the time period when the solar radiation intensity exceeds the threshold value Th1, but it may be a specific time period determined in advance, or may be a time period determined based on other criteria.

[0049] In the example of FIG. 4, day 7, the scheduled hydrogen supply date, is not included in the candidate days for allocating hydrogen production time, but the scheduled hydrogen supply date may be included in the candidate days for allocating hydrogen production time.

[0050] In the example of Figure 4, the hydrogen production time is a continuous period of one day, but it may be divided into two or more periods of one day. For example, if the weather is bad during the day and the solar radiation intensity is expected to decrease, the hydrogen production time may be divided into two or more time periods.

[0051] As described above, according to this embodiment, by using weather forecast data, short-term demand forecasts, and operation data to create a short-term operation plan (hydrogen production plan, etc.) up to the scheduled hydrogen supply date, it is possible to create an operation plan that enables efficient operation of the energy system.

[0052] (Second embodiment) In the first embodiment, a short-term operation plan was created based on weather forecast data and short-term demand forecasts, but in the second embodiment, a method for creating a short-term operation plan taking into account long-term demand forecasts such as NetZero will be described.

[0053] 5 is a block diagram showing an information processing system 1A according to the second embodiment. Compared to the first embodiment, the functions of the operation plan creation device 10A are expanded from those of the first embodiment, and a long-term forecast data management server 93 is connected to the communication network 90.

[0054] The operation plan creation device 10A includes a weather forecast data acquisition unit 11, an operation data acquisition unit 13, a short-term demand forecast data acquisition unit 32, a short-term operation plan creation unit 34, a short-term operation plan data storage unit 35, a long-term forecast data acquisition unit 36, a long-term operation plan creation unit 37, and a long-term operation plan data storage unit 38.

[0055] The weather forecast data acquisition unit 11 and the operation data acquisition unit 13 are the same as those in Fig. 1. In addition, the short-term demand forecast data acquisition unit 32 and the short-term operation plan data storage unit 35 have the same functions as the demand forecast data acquisition unit 12 and the operation plan data storage unit 15 in Fig. 1. Detailed explanations of these elements 11, 13, 32, and 35 will be omitted.

[0056] The long-term forecast data acquisition unit 36 ​​is connected to a long-term forecast data management server 93 via a communication network 90. ​​The long-term forecast data management server 93 manages long-term forecast data on renewable energy power (PV-generated power in this example), long-term forecast data on power demand, and long-term forecast data on hydrogen demand. Specifically, the long-term forecast data management server 93 stores and manages long-term PV power generation forecast data, long-term power demand forecast data (fourth demand data), and long-term hydrogen demand forecast data (third demand data). The long-term hydrogen demand forecast data is an example of third demand data related to the demand amount required for an external device in a second period longer than the first period. The third demand data may be past actual data or statistical data of past actual data, or may be planned data planned in advance by the user. The long-term power demand forecast data is an example of fourth demand data related to the power consumed in the second period longer than the first period. The fourth demand data may be past actual data or statistical data of past actual data, or may be planned data planned in advance by the user.

[0057] FIG. 6 shows, as examples of long-term forecast data, forecast data D1 for annual PV power generation and forecast data D2 for annual power demand. The horizontal axis represents time, and the vertical axis represents power supply and demand. A positive sign for power supply and demand indicates power generation, and a negative sign indicates power consumption. For this reason, forecast data D1 for PV power generation takes a positive value, and forecast data D2 for power demand takes a negative value.

[0058] Figure 7 shows an example of long-term forecast data for annual hydrogen demand forecast for FCVs. The horizontal axis represents time, and the vertical axis represents the amount of hydrogen demand for FCVs (planned amount of hydrogen supply).

[0059] The long-term operation plan creation unit 37 creates a long-term operation plan for the energy system 200 by optimization calculation (for example, calculation using mixed integer programming) based on the long-term forecast data acquired by the long-term forecast data acquisition unit 36. The long-term operation plan creation unit 37 stores data of the created long-term operation plan in the long-term operation plan data storage unit 38. Details of the process of creating a long-term operation plan will be described later.

[0060] The long-term operation plan data storage unit 38 stores data on the long-term operation plan created by the long-term operation plan creation unit 37 .

[0061] FIG. 8 shows a cumulative supply and demand plan for system power (power of power system 800) created by long-term operation plan creation unit 37 based on PV power generation power forecast data D1 and power demand forecast data D2 in FIG. FIG. 9 shows a hydrogen storage amount plan for FCV hydrogen supply created by the long-term operation plan creation unit 37 based on the hydrogen demand forecast data of FIG.

[0062] The short-term operation plan creation unit 34 creates a short-term operation plan by updating the plan portion for the most recent short-term period (target period) in the long-term forecast data, using the long-term operation plan data, the weather forecast data acquired by the weather forecast data acquisition unit 11, the most recent short-term power demand forecast and the most recent short-term hydrogen demand forecast acquired by the short-term demand forecast data acquisition unit 32, and the operation data of the energy system 200 acquired by the operation data acquisition unit 13. The short-term operation plan creation unit 34 stores the created short-term operation plan in the short-term operation plan data storage unit 35.

[0063] The short-term operation plan data storage unit 35 stores data of the short-term operation plan created by the short-term operation plan creation unit 34.

[0064] The control device 400 reads out the short-term operation plan from the short-term operation plan data storage unit 35, and controls the energy system 200 or the renewable energy hydrogen system 100 based on the read out short-term operation plan. The configuration and operation of the control device 400 are the same as those in the first embodiment, and therefore will not be described.

[0065] FIG. 10 is a flowchart showing an example of the processing of the operation plan creation device 10A. The long-term forecast data acquisition unit 36 ​​acquires long-term PV power generation forecast data, long-term power demand forecast data, and long-term hydrogen demand forecast data as long-term forecast data from the long-term forecast data management server 93 (S201).

[0066] The long-term operation plan creation unit 37 creates a long-term operation plan using an optimization method or the like (details will be described later) based on the acquired long-term forecast data (S202). The created long-term operation plan is stored in the long-term operation plan data storage unit 38. The long-term operation plan includes, for example, a cumulative supply and demand plan for grid power and a hydrogen storage capacity plan for FCVs. Once created, the long-term operation plan is used continuously for a predetermined period. The predetermined period is assumed to be sufficiently longer than the period covered by the short-term operation plan.

[0067] The weather forecast data acquisition unit 11 acquires weather forecast data, the short-term demand forecast data acquisition unit 32 acquires short-term demand forecast data, and the operation data acquisition unit 13 acquires system operation data (S203).

[0068] The short-term operation plan creation unit 34 uses the data acquired in step S203 to update the plan portion of the long-term operation plan for the most recent period (target period) that is the target of the short-term demand forecast (S204). The short-term operation plan creation unit 34 uses the updated plan portion as the operation plan for the most recent period (short-term operation plan). In this way, the short-term operation plan creation unit 34 creates a short-term operation plan. The created short-term operation plan is saved in the short-term operation plan data storage unit 35.

[0069] The short-term operation plan creation unit 34 determines whether to continue operation (S108). This determination method may be the same as step S108 in FIG. 3 according to the first embodiment. If operation is to be continued (YES), the process returns to step S101. If operation is not to be continued (NO), the process ends.

[0070] Fig. 11 is a flowchart showing detailed processing for creating a short-term operation plan performed in step S204 of Fig. 10. Step S301 has been added to the flowchart of Fig. 3 according to the first embodiment. Note that step S203 of Fig. 10 described above corresponds to step S101 of Fig. 3, and steps S205 and S206 of Fig. 10 correspond to steps S107 and S108 of Fig. 3, and therefore Fig. 11 does not include steps corresponding to steps S101, S107, and S108 of Fig. 3.

[0071] Next, the short-term operation plan creation unit 34 checks the current amount of hydrogen stored in the hydrogen tank 106 based on the system operation data. The short-term operation plan creation unit 34 also checks the amount of hydrogen supply (guaranteed hydrogen supply amount) that must be supplied to the FCV from the hydrogen supply device 105 on the scheduled date for hydrogen supply to the FCV based on the hydrogen demand forecast, i.e., the predicted value (first demand value) of the hydrogen demand forecast data (S102).

[0072] If the amount of stored hydrogen is less than the guaranteed hydrogen supply amount, that is, if the amount of stored hydrogen is insufficient (NO in S102), the process proceeds to steps S103 and S104, respectively.

[0073] In step S103, the short-term operation plan creation unit 34 calculates the total hydrogen production time required for the hydrogen production device 102 to produce the hydrogen that is in short supply.

[0074] In step S104, the short-term operation plan creation unit 34 compares the amount of solar radiation (or solar radiation intensity) for multiple days within the target period based on the weather forecast data. Based on the amount of solar radiation for each day, the operation plan creation unit 14 determines the priority of the hydrogen production days in the same manner as in the first embodiment, such as in order of the day (period) with the highest amount of solar radiation (S105).

[0075] The operation plan creation unit 14 creates a hydrogen storage capacity plan that allocates the total hydrogen production time to one or more days, similar to the first embodiment, based on the total hydrogen production time calculated in step S103 and the priority of the hydrogen production days determined in step S105.

[0076] On the other hand, if the hydrogen storage amount is equal to or greater than the guaranteed hydrogen supply amount in step S102, the hydrogen storage amount is compared with the predicted storage amount value (second demand value) in the hydrogen storage amount plan in the long-term operation plan (S301).

[0077] If the hydrogen storage amount is greater than the predicted storage amount (YES), that is, if the hydrogen storage amount satisfies the hydrogen storage amount plan, the planned portion of the long-term plan for the target period (in this example, the period up to the scheduled date of hydrogen supply to the FCV) is not updated. The planned portion of the long-term hydrogen storage amount plan for the target period is used as the short-term storage amount plan (operation plan) for hydrogen storage (S302).

[0078] The following describes in detail the process of creating a long-term operation plan by the long-term operation plan creation unit 37. As a method for creating a long-term operation plan, a method using mixed integer programming will be described.

[0079] As input information, long-term forecast data such as those shown in Figures 6 and 7, i.e., PV power generation forecast data, power demand forecast data, and FCV hydrogen demand forecast data, are used. The time length of the long-term forecast data is, for example, annual data in one-hour increments.

[0080] In this example, an optimization problem with the objective of NetZero is formulated. NetZero means that the value obtained by subtracting the amount of power flowing into the power grid (power sold) from the amount of power flowing in from the power grid (power purchased) is zero. The physical quantities (e.g., amount of electricity, amount of hydrogen, etc.) handled by each device in the energy system are used as variables, and an objective function is defined that includes a term that calculates the cumulative amount of power input / output to / from the power grid using the variables as the objective variable. Constraint equations are also defined for each device using the variables. The variable values ​​(time-series data of the variables) are found by minimizing or quasi-minimizing the objective function based on each constraint equation. A long-term operation plan is obtained from the time-series data of the relevant variables found. In this example, the objective is NetZero, and the cumulative amount of power input / output to / from the power grid is minimized. However, in other cases, minimizing costs or CO2 emissions, etc., may also be the objective. In this case, the objective function can be set according to the objective.

[0082] Figure 12 shows each variable associated with the corresponding device in the energy system. The hydrogen supply device 105 (see Figure 1) includes a pre-cooling device 105A that pre-cools the hydrogen to be supplied to the FCV, and this optimization problem also takes into account the power consumption of the pre-cooling device 105A.

[0086] (Constraints on the storage battery 101) For the storage battery 101, a constraint equation is set that stipulates that the charge / discharge power is within the range of the rated value, and a constraint equation that stipulates that the charge amount is within the capacity range. Note that the SOC (State Of Charge) is an index that indicates the amount of power charged to the storage battery, and is expressed as the ratio of the amount of power being charged to the rated charge capacity. TIFF0007824837000005.tif108170

[0087] (Constraints of the hydrogen production device 102) The hydrogen production device 102 is assumed to have two stages of operation, operation and shutdown, and a discrete constraint equation is set such that the rated power is consumed when in operation, and the power consumption is set to zero when in shutdown. TIFF0007824837000006.tif83170

[0088] (Constraints on hydrogen storage capacity) The hydrogen storage devices include a hydrogen tank 103 that stores hydrogen to supply to a fuel cell (FC) 104, and a hydrogen tank 106 that stores hydrogen to supply to an FCV. A constraint equation is set that sets the storage amount of each of the hydrogen tanks 103 and 106 within a capacity range. A constraint is also set that selectively stores hydrogen produced by the hydrogen production device 102 in one of the hydrogen tanks at time k. TIFF0007824837000007.tif82170

[0089] (Fuel cell constraints) For fuel cells, a constraint equation is set to keep the generated power within the rated value range. Since the constraint equation can be created in the same way as for storage batteries, detailed expressions are omitted.

[0090] TIFF0007824837000008.tif37170

[0091] In this embodiment, it is also possible to perform operations similar to those of the first embodiment by using weather forecast data and short-term demand forecasts in the short-term operation plan creation unit 34 to perform processing similar to that of the operation plan creation unit 14 of the first embodiment, without using long-term forecast data and a long-term operation plan. In this case, the short-term operation plan creation unit 34 may perform operations similar to those of the flowchart of Fig. 3 according to the first embodiment.

[0092] As described above, this embodiment makes it possible to create an optimal short-term operation plan for the immediate short-term demand forecast while satisfying a long-term operation plan that exceeds the weather forecast period. By controlling the renewable energy hydrogen system 100 based on the created optimal short-term operation plan, it becomes possible to operate each device in the renewable energy hydrogen system 100 optimally, taking into account long-term indicators such as NetZero.

[0093] (Third embodiment) FIG. 13 is a block diagram showing an example of an information processing system 1B according to the third embodiment. The function of the control device 400 has been expanded or modified from that of the control device 400 of the first or second embodiment (see FIGS. 1 and 5). The control device 400 acquires a hydrogen storage capacity plan P1 and a power supply and demand plan P2 as short-term operation plans created by the operation plan creation device 10B. The operation plan creation device 10B is either the operation plan creation device 10 according to the first embodiment or the operation plan creation device 10A according to the second embodiment. The control device 400 controls the renewable hydrogen system or the energy system based on the hydrogen storage capacity plan P1 and the power supply and demand plan P2.

[0094] The control device 400 includes an operation data collection unit 401, an operation data storage unit 402, a supply and demand balance determination unit 403, a hydrogen storage capacity plan input unit 404, a hydrogen storage capacity plan storage unit 405, a hydrogen storage capacity plan sufficiency determination unit 406, a power supply and demand plan input unit 407, a power supply and demand plan storage unit 408, a power supply and demand plan sufficiency determination unit 409, a control unit 411, and a transmission unit 412.

[0095] The operation data collection unit 401 acquires operation data of the energy system 200. The operation data of the energy system 200 includes some or all of the operation data of the storage battery 101, the operation data of the hydrogen production device 102, the operation data of the fuel cell 104, the operation data of the hydrogen tank 103, the operation data of the hydrogen tank 106, the operation data of the hydrogen supply device 105, the operation data of the solar power generation device 500, the operation data of the power consumer 300, the operation data of the load device 900, and the operation data of the power grid 800. The operation data may be acquired at regular time intervals, or may be acquired by sending an operation data acquisition request from the operation data collection unit 401 to the energy system 200.

[0096] The operational data storage unit 402 stores the operational data acquired by the operational data collection unit 401 therein.

[0097] The supply and demand balance determination unit 403 compares the power generated by the photovoltaic power generation device 500 with the power consumed by power consumption devices such as the power consumer 300 and the load device 900 for the time to be determined, and determines whether the power generated is equal to or greater than the power consumed. In other words, it determines whether the value obtained by subtracting the power consumed from the power generated is equal to or greater than 0. The time to be determined may be the current time (for example, the latest time at regular intervals), or a time in the past or future. The supply and demand balance determination unit 403 provides the result of the determination to the control unit 411.

[0098] The hydrogen storage amount plan input unit 404 receives the hydrogen storage amount plan P1 from the operation plan creation device 10B and saves the hydrogen storage amount plan P1 in the hydrogen storage amount plan memory unit 405. The hydrogen storage amount plan memory unit 405 stores the hydrogen storage amount plan P1 internally.

[0099] The hydrogen storage amount plan sufficiency determination unit 406 determines whether the amount of hydrogen stored in the hydrogen tank 106 at the time being determined satisfies the hydrogen storage amount plan P1. The hydrogen storage amount plan sufficiency determination unit 406 determines whether the amount of hydrogen stored in the hydrogen tank 103 at the time being determined is equal to or greater than the predicted value (threshold) for the time being determined in the hydrogen storage amount plan P1. If the hydrogen storage amount is equal to or greater than the predicted value, the hydrogen storage amount plan sufficiency determination unit 406 determines that the amount of hydrogen stored in the hydrogen tank 103 satisfies the hydrogen storage amount plan P1, and if the hydrogen storage amount is less than the predicted value, it determines that the hydrogen storage amount in the hydrogen tank 103 does not satisfy the hydrogen storage amount plan P1. The hydrogen storage amount plan sufficiency determination unit 406 provides the control unit 411 with the result of its determination.

[0100] The power supply and demand plan input unit 407 receives the power supply and demand plan P2 from the operation plan creation device 10B and saves the power supply and demand plan P2 in the power supply and demand plan storage unit 408. The power supply and demand plan storage unit 408 stores the power supply and demand plan P2 internally.

[0101] The power supply and demand plan fulfillment determination unit 409 determines whether the cumulative amount of power transmitted to and received from the power system 800 at the time being determined fulfills the power supply and demand plan P2. The power supply and demand plan fulfillment determination unit 409 determines whether the cumulative amount of power at the time being determined is equal to or greater than the predicted value (threshold) at the time being determined in the power supply and demand plan P2. If the cumulative amount of power is equal to or less than the predicted value, the power supply and demand plan fulfillment determination unit 409 determines that the cumulative amount of power fulfills the power supply and demand plan P2, and if the cumulative amount of power exceeds the predicted value, it determines that the cumulative amount of power does not fulfill the power supply and demand plan P2. The power supply and demand plan fulfillment determination unit 409 provides the determination result to the control unit 411.

[0102] The control unit 411 acquires information indicating the results of the judgments from the supply and demand balance judgment unit 403, the hydrogen storage amount plan sufficiency judgment unit 406, and the power supply and demand plan sufficiency judgment unit 409, and generates control information for the renewable energy hydrogen system 100 or the energy system 200 based on the acquired information. For example, the control unit 411 determines which process to execute: power generation by the fuel cell 104, production of hydrogen to be stored in the hydrogen tank 106, production of hydrogen to be stored in the hydrogen tank 103, charging of the storage battery 101, discharging of the storage battery 101, selling of electricity to the power grid 800, or purchase of electricity from the power grid 800. For example, if the amount of hydrogen in the hydrogen tank 106 is equal to or greater than a predicted value, the cumulative amount of electricity with the power grid is equal to or less than a predicted value, the amount of PV power generation is equal to or greater than the amount of power consumed, the remaining charge in the storage battery 101 has reached its upper limit, and the amount of hydrogen in the hydrogen tank 106 is less than its upper limit, the control unit 411 determines to produce hydrogen for supply to FCVs. In this way, which process to execute is determined based on predetermined judgment criteria.

[0103] The control unit 411 generates control information (operation command values) that causes the determined processing to be executed by the corresponding element in the renewable hydrogen system 100 or the energy system 200. For example, if it is determined that the hydrogen production device 102 should produce hydrogen to be stored in the hydrogen tank 106, the control unit 411 generates control information that instructs the hydrogen production device 102 to produce a certain amount of hydrogen and store it in the hydrogen tank 106. The control unit 411 provides the generated control information to the transmission unit 412.

[0104] The transmitter 412 transmits control information (operation command values) to the renewable hydrogen system 100. The renewable hydrogen system 100 or the energy system 200 is equipped with a receiver that receives the control information (operation command values). The renewable hydrogen system 100 or the energy system 200 sends the received control information to the device to be controlled (such as the storage battery 101, the hydrogen production device 102, the fuel cell 104, or the hydrogen supply device 105). The device to be controlled may be a load device 900 or an electricity consumer 300.

[0105] (Hardware configuration) Fig. 14 shows the hardware configuration of an information processing device according to the first or second embodiment. The control device 400 in Fig. 13 can also be realized with a similar hardware configuration. The information processing device is configured by a computer device 600.

Data can be input from the external device via the communication device 604. The data input from the external device can be stored in the main memory device 605 or the external memory device 606.

The external storage device 606 is, for example, a hard disk, an optical disk, a flash memory, or a magnetic tape, but is not limited to these.
