Description

[Technical field]

[0001] The present invention relates to an electric power recovery system and a terminal device. [Background technology]

[0002] Conventionally, a technology has been known in which surplus electricity from a solar power generation facility is charged into a storage battery mounted on an electric vehicle, and when the power supply is insufficient, the power is discharged from the electric vehicle's on-board storage battery (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-049339 A Summary of the Invention [Problem to be solved by the invention]

[0004] When a facility such as a factory is equipped with a photovoltaic power generation system, the power generated by the sunlight is not used on non-operation days, and the surplus power is discarded. It is also possible to store the power generated on non-operation days in a storage battery and use the stored power on operation days. However, in a typical factory, the power consumption is so large that the power fully stored in the storage battery is consumed in the factory within a few minutes to an hour. For this reason, the closer the amount of power generated by the sunlight is to the power consumption of the factory, that is, the larger the scale of the photovoltaic power generation system, the more difficult it becomes to store the amount of power generated on one non-operation day in the storage battery. Therefore, if a storage battery with a suitable storage capacity is installed for a few non-operation days per year, the cost of introducing the storage battery will increase, and there is a possibility that more power will be wasted. It is also possible to supply the power generated on non-operation days to the grid, but in this case, a facility is required to reliably prevent the power generated by the sunlight from flowing into the grid during power outages or construction work on the grid side, which increases the cost of introducing the facility.

[0005] The technology described in Patent Document 1 does not take into account days when solar power is not being used, such as non-operational days in a factory equipped with solar power generation equipment, and therefore has the problem of being unable to efficiently recover surplus electricity on days when electricity is not being used.

[0006] In view of the above problems, an object of the present disclosure is to provide an electricity recovery system and a terminal device that can recover electricity generated by solar power generation equipment on non-electricity usage days when a facility equipped with solar power generation equipment does not use electricity generated by sunlight. [Means for solving the problem]

[0007] The gist of the present disclosure is as follows.

The non-electric power use days are days when the facility does not use electric power generated by solar power. The electric power recovery system includes a non-electric power use day acquisition unit and a recovery command transmission unit. The non-electric power use day acquisition unit acquires information regarding days when electric power is not being used. The recovery command transmission unit transmits a recovery command. The recovery command is a command to drive a vehicle equipped with a storage battery to the facility on the non-electric power use day, and to store surplus electric power generated by the solar power generation equipment on the non-electric power use day in the storage battery and recover it.

[0012] (5) In the power recovery system described above in (3), the priority determination unit determines the priority when transmitting the recovery command to multiple vehicles based on at least one of the storage capacity of the storage battery, the charging state of the storage battery, and location information of the vehicle.

[0013] (6) The power recovery system according to (4) above, further comprising a power generation prediction unit. The power generation prediction unit predicts the amount of power generated by the solar power generation facility on the non-power usage day.

[0025] Hereinafter, some embodiments according to the present disclosure will be described with reference to the drawings. However, these descriptions are intended to merely exemplify preferred embodiments of the present disclosure, and are not intended to limit the present disclosure to such specific embodiments. In the following description, similar components are given the same reference numerals, and duplicate descriptions will be omitted as appropriate.

[0026] As an example, the solar power generation control system 100 according to the present embodiment is a solar power generation facility including a solar panel, and is used in the form of a completely self-consumption on-site PPA. In the on-site PPA, as shown in FIG. 1, a power generation company 300 installs the control system 100 on the premises of a consumer 350, and supplies the power generated by the control system 100 to the consumer 350 on-site (on-site). The power generation company 300 and the consumer 350 enter into a power purchase agreement, i.e., a PPA. Based on the PPA, the power generation company 300 installs the control system 100, and also owns and manages the control system 100. Based on the PPA, the consumer 350 pays the power fee to the power generation company 300.

[0027] In the case of a completely self-consumption type, all of the power generated by the control system 100 is self-consumed within the premises of the consumer 350. Therefore, the power generated by the control system 100 is supplied only to facilities within the premises of the consumer 350, and the power is not supplied to the power transmission network or distribution network of other power systems.

[0028] When the amount of power generated by the control system 100 is surplus to the amount of power required by the consumer 350, the surplus is stored in the storage battery. When the amount of power generated by the control system 100 is insufficient to the amount of power required by the consumer 350, the shortage is made up for by the power stored in the storage battery. The shortage may also be made up by the consumer 350 purchasing power from an existing power company 400. As will be described later, in this embodiment, since solar power generation power is collected on days when power is not used, the control system 100 does not necessarily need to include a storage battery. On the other hand, the control system 100 may include a storage battery, for example, assuming use in an emergency.

[0029] In this embodiment, a case where the consumer 350 is a factory owner is illustrated. The power generation business operator 300 installs the control system 100 shown in FIG. 1 in a factory 500 shown in FIG. 2. The consumer 350 may be someone other than the factory owner, and the control system 100 may be installed in a facility, building, or the like other than the factory 500. The control system 100 includes a solar panel 102, and the solar panel 102 is installed on the roof of the factory 500, for example. The control system 100 supplies electricity generated by solar power generation to various facilities provided in the factory 500.

[0030] In the factory 500, the power generated by the solar panel 102 every day is often consumed by various facilities in the factory 500 on the same day. On the other hand, even on non-operation days, i.e., holidays, the solar panel 102 generates power, but if the facilities that consume the power are not operating, the generated power is discarded without being consumed. From the viewpoint of effective use of power generated by solar power generation, it is preferable to store the power generated on non-operation days of the factory 500 in a storage battery and consume the stored power on the operation days of the factory. However, the non-operation days of the factory 500 may be only a few days a year, and if the factory 500 has a suitable storage battery for the few non-operation days, the cost of introducing the storage battery increases and there is a possibility of a large waste. In addition, when the power generated on non-operation days is supplied to the grid, a facility is required to reliably prevent the power generated by the solar power from flowing into the grid during power outages or construction work on the grid side, and the cost of introducing the facility increases.

[0031] As described above, in a facility such as the factory 500 equipped with a solar power generation system, it is desirable to effectively utilize the power generated by solar power generation on non-power use days such as non-operation days when power is not used. In this embodiment, a command to collect the power generated by solar power generation on the non-power use days of each factory 500 is transmitted to a vehicle equipped with a storage battery or a terminal device of a user. The user is specifically a driver of the vehicle. Based on this command, the vehicle 800 equipped with a storage battery 805 is driven to the factory 500 on the non-power use day of the factory 500 as shown in FIG. 3. Then, while the vehicle 800 is parked within the premises of the factory 500, the charging cable on the vehicle 800 side is connected to a power supply connector installed in the factory 500, and the power generated by the solar panel 102 of the factory 500 on the non-power use day is stored in the storage battery 805 of the vehicle 800. Therefore, it is possible to prevent the power generated on the non-power use day of the factory 500 from being discarded and wasted.

[0032] A non-power usage day refers to a day on which a facility equipped with solar power generation equipment does not use electricity generated by solar power generation. A non-power usage day is not necessarily limited to a day on which a facility equipped with solar power generation equipment does not use any electricity generated by solar power generation. A non-power usage day may be a day on which the daily power usage is equal to or less than a specified percentage of the normal daily power usage. Here, the normal daily power usage may be the annual average daily power usage on the operating days of the factory 500, or the value obtained by dividing the annual power usage of the factory 500 by 365 days.

[0033] For example, a non-power usage day may be a day on which the equipment for maintaining the manufacturing environment is in operation but the manufacturing equipment is stopped, and therefore the daily power usage is 5% to 10% of the normal daily power usage. Examples of days on which the daily power usage is 5% to 10% of the normal daily power usage include Saturdays and Sundays on the weekend.

[0034] Furthermore, a non-power usage day may be a day on which the factory does not experience a power outage, but most of the factory equipment is stopped, so that the daily power usage is not completely zero, but is less than 5% of the normal daily power usage. A non-power usage day may also be a day on which the factory experiences a complete power outage, so that the daily power usage is completely zero. Examples of days on which the daily power usage is completely zero include regular maintenance days, which occur once or twice a year.

[0035] The vehicle 800 and the storage battery 805 may be owned by the power generation company 300. In this case, the command may be transmitted to the vehicle 800 owned by the power generation company 300 or to a terminal device owned by an employee of the power generation company 300. The employee who receives the command drives the vehicle 800 to the factory 500 on a day when the factory 500 does not use electricity, and collects electricity generated by solar power generation. Also, the vehicle 800 who receives the command may automatically drive to the factory 500 on a day when the factory 500 does not use electricity, and collect electricity generated by solar power generation. The storage battery 805 with stored electricity may be transported by the vehicle 800 to a base of the power generation company 300 and collected at the base of the power generation company 300, as shown in FIG. 3.

[0036] On the other hand, the vehicle 800 may be an electric vehicle or a hybrid vehicle as a private vehicle, and the storage battery 805 may be a vehicle battery provided in the electric vehicle or the hybrid vehicle. In this case, the person who received the command drives the vehicle 800 to the factory 500 on a day when the factory 500 does not use electricity, and collects electricity generated by solar power generation. The electricity stored in the storage battery 805 can be used as electricity for driving the vehicle 800 or as electricity used in general households. Therefore, the factory 500 can also function as a charging station that can be used by the general public. Even in this case, the vehicle 800 that received the command may automatically drive to the factory 500 on a day when the factory 500 does not use electricity, and collect electricity generated by solar power generation. When the electricity generated by solar power generation is collected, the owner of the vehicle 800 pays the electricity fee to the power generation company 300.

[0037] When there is a power purchase request from the power consumption area 950, the vehicle 800 is driven to the consumption area 950 as shown in FIG. 3. Then, the power stored in the storage battery 805 is consumed at the consumption area 950. In this case, in accordance with the power purchase request, a power selling command to sell the power stored in the storage battery 805 at the consumption area 950 is transmitted to the vehicle 800 or a user's terminal device. Based on this command, the vehicle 800 equipped with the storage battery 805 that has stored power is driven to the consumption area 950. Then, while the vehicle 800 is parked within the premises of the consumption area 950, a power supply cable on the vehicle 800 side is connected to a charging connector at the consumption area, and the power stored in the storage battery 805 is supplied to the consumption area 950.

[0038] The consumption location 950 may be, for example, a location where an agricultural greenhouse is installed. In the agricultural greenhouse, electricity may be required for heating and cooling the greenhouse depending on weather conditions. In such a case, the consumption location 950 issues a power purchase request.

[0039] The consumption site 950 may be a place where a storage battery is installed and the power stored in the storage battery is used. When the capacity of the power stored in the storage battery is insufficient, the consumption site 950 issues a power purchase request. Examples of such consumption sites 950 include other factories, schools, housing complexes, and shopping malls. Examples of cases in which the capacity of the power stored in the storage battery is insufficient include power outages caused by natural disasters, including earthquakes and floods. Some facilities are introducing storage batteries so that they can continue business for approximately 72 hours in an emergency, but most facilities are expected to experience power shortages during power outages, and if the power outage continues for a long time, the capacity of the storage battery may be depleted.

[0040] In response to the power purchase request, the power stored in the storage battery 805 is supplied to the consumption area 950, so that the power generated on days when the factory 500 does not use power is effectively utilized in the consumption area 950, and the power generation company 300 can make a profit by selling the power. Also, if the vehicle 800 is a private vehicle, the owner of the vehicle 800 can earn income by selling the power. In addition, in the event of a natural disaster, it is desirable for the cost of selling the power to be compensated by a public institution.

[0041] As shown in FIG. 4, the power recovery system 1000 includes a terminal device 510 of each factory 500 and a server 600. The server 600 may be owned by the power generation company 300. The power recovery system 1000 may include a vehicle 800, a user's terminal device 900, and a terminal device 960 of a consumption area 950 in addition to the server 600. The vehicle 800, the terminal devices 510, 900, and 960, and the server 600 can communicate with each other via a communication network 700 configured with an optical communication line or the like and a wireless base station 720 connected to the communication network 700 via a gateway (not shown). That is, the communication network 700 and the wireless base station 720 relay the communication between the vehicle 800, the terminal devices 510, 900, and 960, and the server 600.

[0042] As shown in FIG. 5, the server 600 includes a control device 610 and a storage device 620.

[0043] The control device 610 includes a processor 612, a memory 614, and a communication interface 616. The processor 612 includes one or more CPUs (Central Processing Units) and their peripheral circuits. The processor 612 may further include other arithmetic circuits such as a logic arithmetic unit, a numerical arithmetic unit, or a graphic processing unit. The memory 614 includes, for example, a volatile semiconductor memory and a non-volatile semiconductor memory. The communication interface 616 corresponds to the communication I / F shown in FIG. 5 and includes an interface circuit for connecting the control device 610 to a network in the server 600 or the communication network 700. The communication interface 616 is configured to be able to communicate with the vehicle 800 and the terminal devices 510, 900, and 960 via the communication network 700 and the wireless base station 720. That is, the communication interface 616 passes signals received from the vehicle 800 or the terminal devices 510, 900, 960 via the wireless base station 720 and the communication network 700, i.e., signals of days when electricity is not used, location information, electricity purchase request, and payment information, to the processor 612. Also, the communication interface 616 transmits signals received from the processor 612, i.e., signals of a collection command and an electricity sale command, to the vehicle 800 or the terminal device 900 via the communication network 700 and the wireless base station 720. Note that the server 600, the terminal device 510, and the terminal device 960 may be configured to be able to communicate with each other via the communication network 700 without via the wireless base station 720.

[0044] The storage device 620 includes, for example, a hard disk device or an optical recording medium and an access device therefor. The storage device 620 stores various information such as the days when power is not used in the factory 500 and the address of the factory 500. The storage device 620 may store a computer program for executing the processes executed on the processor 612.

[0045] As shown in Fig. 6, the vehicle control system mounted on the vehicle 800 includes a positioning information receiver 810, a vehicle control device 820, a wireless terminal 830, one or more sensors 840, a navigation device 850, an electronic control unit (ECU) 860, a display device 870, and a speaker 880. These components are communicatively connected via an in-vehicle network conforming to standards such as a Controller Area Network and Ethernet (registered trademark). In the following, the electronic control device 860 is simply referred to as the ECU 860. The hardware functions of the user's terminal device 900 are configured in the same manner as in Fig. 6. However, the user's terminal device 900 does not include the vehicle control device 820. On the other hand, the user's terminal device 900 may include the vehicle control device 820.

[0046] The positioning information receiver 810 acquires positioning information indicating the current position and attitude of the vehicle 800. For example, the positioning information receiver 810 may be a GPS (Global Positioning System) receiver. Every time the positioning information receiver 810 receives positioning information, the positioning information receiver 810 outputs the acquired positioning information together with time information to the ECU 860 via the in-vehicle network.

[0047] Vehicle control equipment 820 is various equipment related to vehicle control, and includes an engine or motor as a drive source for running vehicle 800, a steering device, a braking device, and a vehicle battery for storing electric power.

[0048] The wireless terminal 830 includes, for example, an antenna and a signal processing circuit that executes various processes related to wireless communication, such as modulation and demodulation of a wireless signal. The wireless terminal 830 receives a downlink wireless signal from the wireless base station 720, and transmits an uplink wireless signal to the wireless base station 720. That is, the wireless terminal 830 extracts signals transmitted from the server 600 to the vehicle 800, i.e., a collection command and a power selling command, from the downlink wireless signal received from the wireless base station 720, and passes the signals to the ECU 860. The wireless terminal 830 also generates an uplink wireless signal including the signal received from the ECU 860 and transmitted to the server 600, and transmits the wireless signal.

[0049] The one or more sensors 840 include a sensor that detects a current value or a voltage value of a motor of the vehicle control device 820. The one or more sensors 840 also include a voltage sensor that detects a terminal current or terminal voltage of a battery.

[0050] The navigation device 850 determines a planned driving route from the current location of the vehicle 800 to the destination according to a predetermined route search method such as Dijkstra's algorithm. For this purpose, the navigation device 850 is provided with a memory for storing map information. The navigation device 850 determines a planned driving route from the current location of the vehicle 800 to the collection destination or the electricity selling destination based on the address of the collection destination included in the collection command or the address of the electricity selling destination included in the electricity selling command. The map information may be stored in the memory 864 of the ECU 860.

[0051] The ECU 860 has a processor 862, a memory 864, and a communication interface 866. The processor 862 has one or more CPUs (Central Processing Units) and their peripheral circuits. The processor 862 may further have other arithmetic circuits such as a logic arithmetic unit, a numerical arithmetic unit, or a graphic processing unit. The memory 864 has, for example, a volatile semiconductor memory and a non-volatile semiconductor memory. Various information is stored in the memory 864. The communication interface 866 corresponds to the communication I / F shown in FIG. 6, and has an interface circuit for connecting the ECU 860 to an in-vehicle network.

[0052] The display device 870 is composed of, for example, a liquid crystal display (LCD), is provided near the meter panel or dashboard, and displays the collection command and the electricity selling command received from the server 600. The display device 870 also displays the planned driving route from the current location of the vehicle 800 to the collection destination or the electricity selling destination, which is determined by the navigation device 850. The speaker 880 issues the collection command and the electricity selling command received from the server 600 by voice.

[0053] As shown in FIG. 7, the processor 612 of the control device 610 of the server 600 includes a non-electricity usage date acquisition unit 612a, a location information acquisition unit 612b, a collection command transmission unit 612c, an electric power purchase request reception unit 612d, an electric power sale command transmission unit 612e, an information acquisition unit 612f, an electric power generation amount prediction unit 612g, a priority order determination unit 612h, a learning unit 612i, and a settlement processing unit 612j. Each of these units of the processor 612 is a functional module realized by a computer program that runs on the processor 612, for example. That is, each of these units of the processor 612 is composed of the processor 612 and a program (software) for making the processor 612 function. The program may be recorded in the memory 614 of the control device 610 or a recording medium connected from the outside. Alternatively, each of these units of the processor 612 may be a dedicated arithmetic circuit provided in the processor 612.

[0054] The non-power usage day acquisition unit 612a acquires information on non-power usage days from the terminal device 510 of each factory 500. A non-power usage day is a day on which a facility equipped with solar power generation equipment, i.e., the factory 500, does not use solar power generation. A list of non-power usage days for each factory 500 acquired by the non-power usage day acquisition unit 612a is shown in FIG. 8. The list of non-power usage days shown in FIG. 8 is stored in the memory 614 of the control device 610.

[0055] The location information acquiring unit 612 b acquires location information, ie, the address, of each factory 500 from the terminal device 510 of each factory 500 .

[0056] The collection command transmission unit 612c transmits a collection command to drive the vehicle 800 equipped with the storage battery 805 to a facility equipped with a solar power generation facility on a day when power is not being used, and to store and collect surplus power generated by the solar power generation facility on the day when power is not being used in the storage battery 805. The collection command transmission unit 612c transmits the collection command to the vehicle 800 or the user's terminal device 900. The collection command includes location information of the facility from which the power is to be collected, i.e., the address of the factory 500.

[0057] The power purchase request receiving unit 612d receives a power purchase request from the power consumption area 950. Specifically, the power purchase request receiving unit 612d receives a power purchase request transmitted from a terminal device 960 in the consumption area 950. For example, in a case where an agricultural greenhouse is installed in the consumption area 950, if the expected minimum temperature predicted based on a weather forecast is lower than a predetermined threshold, the temperature of the greenhouse will drop below the expected temperature. In such a case, the terminal device 960 in the consumption area 950 transmits a power purchase request to the server 600. In addition, in a case where a storage battery is installed in the consumption area 950 and the power stored in the storage battery is used in the consumption area 950, when the state of charge SOC of the storage battery drops below a predetermined threshold, the terminal device 960 in the consumption area 950 transmits a power purchase request to the server 600. The power purchase request includes location information of the consumption area 950, i.e., the address.

[0058] The power selling command transmission unit 612e transmits a power selling command to drive the vehicle 800 to the consumption place 950 and sell the power stored in the storage battery 805 at the consumption place 950 based on the power purchase request. The power selling command transmission unit 612e transmits the power selling command to the vehicle 800 or the user's terminal device 900. The power selling command includes location information of the consumption place 950, i.e., the address.

[0059] The information acquisition unit f acquires, via the communication network 700, the identification information of each vehicle 800, the position information of each vehicle 800, the storage capacity of the storage battery 805 of each vehicle 800, and the SOC of the storage battery 805 of each vehicle 800. Furthermore, the information acquisition unit f acquires the identification information of each terminal device 900 and the position information of each terminal device 900. Furthermore, when the vehicle 800 and the terminal device 900 are linked, the information acquisition unit f acquires the identification information of the terminal device 900 linked to the identification information of the vehicle 800. Furthermore, the information acquisition unit f acquires weather information from an external server connected via the communication network 700.

[0060] The power generation amount prediction unit 612g predicts the amount of power generated by the solar panel 102. For example, the power generation amount prediction unit 612g predicts the amount of power generated by the solar panel 102 based on meteorological information acquired by the information acquisition unit 210F from an external server.

[0061] The power generation prediction unit 612g may be configured with a trained model that has been machine-learned to predict the power generation amount of the solar panel 102. In this case, the learning unit 210i may, for example, receive input values ​​x1, x2, x3, x4, and x5, and training data y t A trained model is created from multiple datasets consisting of the training data y t is being calculated, and the output value from the output layer for this input value is y. If the squared error is used as the error function, the squared error E is E=(1 / 2)·(yy t ) 2 It can be calculated as follows.

[0062] The learning unit 210i inputs the input values ​​included in the data set to the neural network, and calculates the output value y obtained and the training data y included in the data set. t Then, in order to minimize the sum of the squared errors E obtained from a plurality of learning data sets, the learning unit 210i performs, for example, backpropagation, stochastic gradient descent, or other calculations to calculate the weights w and biases b of each node, thereby creating a learned model. Note that, if teacher data cannot be detected, the learning unit 210i may create a learned model by unsupervised learning or reinforcement learning.

[0063] When the learning unit 210e creates a trained model corresponding to the power generation amount prediction unit 612g, the input values ​​x1, x2, x3, x4, and x5 are, for example, meteorological information such as the amount of solar radiation, weather, temperature, and wind force. t is the actual value of the amount of power generated by the solar panel 102. As a result, when parameters such as the amount of solar radiation, weather, temperature, and wind power are input to the created trained model, a predicted value of the amount of power generated by the solar panel 102 is output from the trained model.

[0064] When there are multiple vehicles 800 or terminal devices 900, the priority order determination unit 612h determines the priority order when transmitting a collection command or an electricity selling command to the multiple vehicles 800 or the user's terminal devices 900. When there are multiple candidates for the vehicle 800 as the destination of the collection command or the electricity selling command, the priority order determination unit 612h may determine the destination based on the storage capacity of the storage battery 805 that can be stored, the SOC, or the amount of stored electricity of the storage battery 805 acquired by the information acquisition unit f. The amount of stored electricity of the storage battery 805 is calculated by multiplying the storage capacity of the storage battery 805 by the SOC.

[0065] For example, when there are multiple candidates for the destination of the collection command among vehicles 800, the priority order determination unit 612h preferentially determines, as the destination of the collection command, a vehicle 800 having a lower SOC or a lower amount of stored power in the on-board storage battery 805. Also, for example, when there are multiple candidates for the destination of the power sale command among vehicles 800, the priority order determination unit 612h preferentially determines, as the destination of the power sale command, a vehicle 800 having a higher SOC or a higher amount of stored power in the on-board storage battery 805.

[0066] Furthermore, when there are multiple candidates for the vehicles 800 as destinations of the collection command or the power sale command, the priority order determination unit 612h may determine the destination based on the position information of each vehicle 800. When there are multiple candidates for the terminal devices 900 as destinations of the collection command or the power sale command, the priority order determination unit 612h may determine the destination based on the position information of each terminal device 900.

[0067] For example, the priority order determination unit 612h determines, as a destination of the power collection command, with priority to the vehicle 800 or the terminal device 900 whose current location is closer to the factory 500 that collects power. Also, for example, the priority order determination unit 612h determines, as a destination of the power sale command, with priority to the vehicle 800 or the terminal device 900 whose current location is closer to the consumption area 950 where the power is sold.

[0068] When there are a plurality of candidates for the vehicle 800 as the destination of the collection command or the power selling command, the priority order determination unit 612h may determine the destination based on at least one of the charge capacity that the storage battery 805 of each vehicle 800 can charge, the SOC or the amount of stored power of the storage battery 805, and the position information of each vehicle 800. For example, the priority order determination unit 612h may preferentially determine, as the destination of the collection command, a vehicle 800 located closer to the factory 500 that collects the power, from among the vehicles 800 whose storage batteries 805 have an SOC of 50% or less. More preferably, the priority order determination unit 612h may normalize and sum the positional relationship between the factory 500 and the vehicle 800, the storage capacity of the storage battery 805, and the SOC of the storage battery 805 to obtain an index of ease of collection, and determine the priority order in the order of ease of collection. Also, for example, the priority order determination unit 612h may preferentially determine, as a destination of a power selling command, a vehicle 800 located closer to the consumption place 950 to which the power is sold, from among the vehicles 800 whose storage battery 805 has an SOC exceeding 50%. More preferably, the priority order determination unit 612h may normalize and sum up the positional relationship between the consumption place 950 and the vehicle 800, the power storage capacity of the storage battery 805, and the SOC of the storage battery 805 to use it as an index of ease of power selling, and may determine the priority order in order of ease of power selling.

[0069] Furthermore, the priority order determination unit 612h may be configured with a trained model that has been machine-learned to determine the priority order of destinations when sending a collection command or a power selling command. Taking a collection command as an example, the learning unit 210i, as in the above, may train an input value and training data y t A trained model is created from a plurality of data sets consisting of the above. When the learning unit 210i creates a trained model for determining the priority order when sending a collection command, the input values ​​x1, x2, x3, x4, and x5 are the location of the factory 500 from which the power is collected, the location of each vehicle 800, the storage capacity of the storage battery 805 of each vehicle 800, and the SOC of the storage battery 805 of each vehicle 800 at the time when the collection command was sent in the learning stage. In addition, the training data y tis the location of the vehicle 800 that actually recovered power in the factory 500, the storage capacity of the storage battery 805, and the SOC of the storage battery 805 at the time when the recovery command was sent, and the location of the factory 500 where the power was recovered. t may be expressed as an index of ease of recovery by normalizing and integrating the positional relationship between the factory 500 and the vehicle 800, the storage capacity, and the SOC. In this way, when the position of each vehicle 800, the storage capacity and SOC of the storage battery 805 of each vehicle 800, and the position of the factory 500 where the power is to be recovered at the time of transmitting the recovery command are input to the created trained model, the training data y t The priority order determination unit 612h calculates a similar index for each vehicle 800 at the time of transmitting the collection command, and determines the priority order in order of closestness to the index output from the trained model.

[0070] When the learning unit 210i creates a trained model for determining the priority order when sending a power sale command, the trained model is created in the same way as in the case of a collection command. In this case, the input values ​​may include the amount of power requested by the consumption area 950 in addition to the location information, power storage capacity, and SOC. In this way, when the location information, power storage capacity, SOC, and power amount requested by the consumption area 950 of each vehicle 800 at the time of sending a power sale command are input to the created trained model, the teacher data y t An index indicating the ease of selling electricity corresponding to the collected electricity is output. The priority order determination unit 612h determines the priority order based on this index, similar to the collection command.

[0071] When transmitting a collection command to a plurality of vehicles 800, the collection command transmission unit 612c may transmit the collection command to a predetermined number of vehicles 800 with higher priority according to the priority determined by the priority determination unit 612h. In this case, the collection command transmission unit 612c compares the amount of power generated by the control system 100 on a non-power usage day with the remaining capacity of the storage battery 805 of the vehicle 800 transmitting the collection command. Then, the collection command transmission unit 612c may determine the above-mentioned predetermined number so that the total remaining capacity of the storage battery 805 of the vehicle 800 transmitting the collection command is greater than the amount of power generated by the control system 100 on a non-power usage day, and transmit the collection command to the predetermined number of vehicles 800. This makes it possible to store power in the storage battery 805 of all the vehicles 800 that have been sent for collection, and suppresses the occurrence of a vehicle 800 that has been sent for collection but cannot store power in the storage battery 805. The amount of power generated by the control system 100 on a non-power usage day is predicted by the power generation amount prediction unit 612g.

[0072] The payment processing unit 612j receives payment information from the vehicle 800 that collected the power or the user's terminal device 900, and performs payment processing when the conditions required for payment are met. This completes the purchase procedure for the collected power by the user of the vehicle 800. Note that the payment processing may be performed only when the surplus power is collected by a general public. In other words, when the power generation company 300 owns the vehicle 800 and the storage battery 805 and collects the power, the collected power continues to be owned by the power generation company 300, so the payment processing may not be performed.

[0073] The processor 862 of the vehicle 8009ECU860 is one aspect of the terminal device mounted on the vehicle. As shown in FIG. 9, the processor 862 has a collection command receiving unit 862a, an electricity selling command receiving unit 862b, a display processing unit 862c, a vehicle control unit 862d, and a payment information transmitting unit 862e. Each of these units of the processor 862 is a functional module realized by a computer program that runs on the processor 862, for example. That is, each of these units of the processor 862 is composed of the processor 862 and a program (software) for making it function. The program may be recorded in the memory 864 of the ECU 860 or a recording medium connected from the outside. Alternatively, each of these units of the processor 862 may be a dedicated arithmetic circuit provided in the processor 862. The processor of the terminal device 900 is also configured in the same manner as the processor 862 of the ECU 860 shown in FIG. 9, but the processor of the terminal device 900 does not include the vehicle control unit 862d.

[0074] The recovery command receiving unit 862a receives a recovery command from the server 600 to drive the vehicle 800 equipped with the storage battery 805 to the facility on a non-power usage day when the facility equipped with the solar power generation equipment does not use electricity generated by solar power generation, and to have the storage battery 805 recover surplus electricity generated by the solar power generation equipment on the non-power usage day.

[0075] The power sale command receiving unit 862b receives a power sale command from the server 600 to drive the vehicle 800 to the power consumption location 950 based on a power purchase request from the power consumption location 950 and sell the power stored in the storage battery 805 at the power consumption location 950.

[0076] The display processing unit 862c performs processing for displaying the collection command or the power selling command on the display device 870. As shown in an example of the display of the collection command in FIG. 10, the display device 870 displays information such as that the factory A is on a non-power usage day, that the vehicle 800 equipped with the storage battery 805 is driven to the factory A to encourage power collection, the address of the factory A, and the like. Also, as shown in an example of the display of the power selling command in FIG. 11, the display device 870 displays information such as that there is a consumption area that requires power, that the vehicle 800 equipped with the storage battery 805 is driven to the consumption area to encourage power sales, the address of the consumption area, and the like. Therefore, the driver of the vehicle 800 who sees these displays can drive the vehicle 800 to the factory A to collect power, or drive the vehicle 800 to the consumption area to sell the power stored in the storage battery 805.

[0077] The vehicle control unit 862d controls the vehicle control device 820 based on the collection command to drive the vehicle 800 to the factory 500 on the non-electricity usage day. The vehicle control unit 862d also controls the vehicle control device 820 based on the power sale command to drive the vehicle 800 to the consumption location 950. At this time, the vehicle control unit 862d drives the vehicle 800 to the factory 500 or the consumption location 950 according to a planned driving route to the collection destination factory 500 or the power sale destination consumption location 950, which is determined by the navigation device 850.

[0078] When the vehicle 800 recovers electric power, the payment information transmission unit 862e transmits payment information to the server 600. The payment information may include identification information of the vehicle 800, identification information of the user's terminal device 900, the amount of recovered electric power, the user's address and name, or credit card information for payment. When the server 600 receives the payment information, the payment processing unit 612j of the server 600 performs payment processing.

[0079] Furthermore, when the vehicle 800 purchases electricity in the consumption area, the payment information transmission unit 862e transmits payment information to the terminal device 960 in the consumption area. The payment information may include identification information of the vehicle 800, identification information of the user's terminal device 900, a transfer destination for the electricity sale fee, the user's address and name, or the amount of electricity sold. When the terminal device 960 receives the payment information and the electricity sale fee is transferred to the user's account, the payment is completed.

[0080] The time-series flow of the above-mentioned processing of the processor 612 of the server 600 and the processor 862 of the ECU 860 will be described with reference to Fig. 12. First, the non-power usage day acquisition unit 612a of the processor 612 acquires non-power usage days from the terminal device 510 of each factory 500 (step S10). Next, the location information acquisition unit 612b acquires location information of each factory 500 from the terminal device 510 of each factory 500 (step S12). Next, it is determined whether or not it is a non-power usage day (step S14), and if it is a non-power usage day, the collection command transmission unit 612c transmits a collection command to collect the electricity generated by solar power generation on the non-power usage day of each factory 500 (step S16).

[0081] Next, the collection command receiving unit 862a of the processor 862 determines whether or not it has received a collection command (step S20), and if the collection command receiving unit 862a has received a collection command, the display processing unit 862c performs processing for displaying the collection command on the display device 870 (step S22). As a result, the driver of the vehicle 800 drives the vehicle 800 to the factory 500 on the day when electricity is not being used, based on the collection command displayed on the display device 870. Alternatively, in step S22, the vehicle control unit 862d automatically drives the vehicle 800 to the factory 500 on the day when electricity is not being used, based on the collection command.

[0082] The chronological flow of processing when a power purchase request is issued from the consumption area 950 will be described with reference to Fig. 13. First, the terminal device 960 of the consumption area 950 transmits a power purchase request to the server 600 (step S30). Next, the power purchase request receiving unit 612d of the processor 612 of the server 600 determines whether or not the power purchase request has been received (step S40), and if a power purchase request has been received, the power sale command transmitting unit 612e transmits a power sale command (step S42).

[0083] Next, the power selling command receiving unit 862b of the processor 862 of the ECU 860 determines whether or not it has received a power selling command (step S50), and if it has received a power selling command, the display processing unit 862c performs processing for displaying the power selling command on the display device 870 (step S52). As a result, the driver of the vehicle 800 drives the vehicle 800 to the consumption place 950 based on the power selling command displayed on the display device 870. Alternatively, in step S52, the vehicle control unit 862d automatically drives the vehicle 800 to the consumption place 950 based on the power selling command.

[0084] As described above, according to the power recovery system of this embodiment, on days when the factory 500 does not use electricity, the vehicle 800 equipped with the storage battery 805 is driven to the factory 500 to recover electricity generated by solar power. This prevents electricity generated by solar power from being wasted on days when electricity is not used. There is no need to provide a storage battery in the factory to store electricity generated on days when electricity is not used, and there is no need to provide equipment to supply electricity from the factory 500 to the grid, so the introduction cost of the power recovery system is reduced.
