Therefore, description of the power generation device, the stationary battery, and the power control device in the stores 12 to 14 is omitted.
In the present embodiment, it is assumed that it is determined that the vehicle 110 departs from the base 10 and then returns to the base 10 via the store 11, the store 12, and the store 13 in order. The vehicle control device 60 acquires a delivery demand indicating an item that each store desires to hand over on the next day from the stores 11 to 14, and transmits, as delivery schedule information, the delivery demand to the integrated control device 50. In addition, the power control devices 40 to 44 predict the power consumption and the power generation amount of the power generation devices 20 to 24 on the next day in each base 10 and the stores 11 to 14, and transmit, as power demand information, the predicted power consumption and power generation amount to the integrated control device 50. The integrated control device 50 decides the time when the vehicle 110 arrives at each of the stores 11 to 14 and the time when the vehicle departs to satisfy the delivery demand indicated by the delivery schedule information and the power demand information in each base 10 and the stores 11 to 14, and causes the traveling battery of the vehicle 110 and the stores 11 to 14 to perform power transmission/reception to/from each other when the vehicle 110 stops at each of the stores 11 to 14 and unloads items. Note that stands 71 to 74 are charging stands installed outside the stores 11 to 14. When determining that the battery of the vehicle 110 needs to be subjected to supplementary charging at any one stand of the stands 71 to 74, the integrated control device 50 may decide operation information having the stand as a stopover and cause the traveling battery to be charged at the stand according to the decided operation information.

The calculation unit 200 is realized by, for example, a calculation processing device including a processor. The storage unit 280 is realized to include a nonvolatile storage medium. The calculation unit 200 performs processing by using the information stored in the storage unit 280. The communication unit 290 is responsible for communication with the power control devices 40 to 44, the vehicle control device 60, and the vehicle 110. The calculation unit 200 communicates with the outside through the communication unit 290.
The acquisition unit 210 acquires (I) a first demand sent from an energy control device which controls energy and including a demand amount, a demand time, and a demand position related to an energy demand, and (II) a second demand sent from a moving body control device which controls a moving body and including a demand amount, a demand time, and a demand position related to a demand of the moving body.

When determining that it is not possible to satisfy the both demands of the first demand and the second demand, the processing unit 220 may decide the position and the time at which the moving body moves by giving priority to one of the first demand and the second demand over the other.
When determining that it is not possible to satisfy the both demands of the first demand and the second demand, the processing unit 220 may decide the position and the time, at which the moving body moves, to satisfy at least the second demand and satisfy at least the demand amount and the demand time at some predetermined demand positions among a plurality of demand positions including the demand position that are included in the first demand.
The processing unit 220 may decide, on the basis of the first demand, the position and the time at which the moving body moves, and determine, on the basis of the position and the time at which the moving body moves and which are decided on the basis of the first demand, whether the second demand is satisfied.
After the moving body starts moving on the basis of the position and the time at which the moving body moves decided on the basis of the first demand and the second demand, the processing unit 220 may re-decide the position and the time, at which the moving body moves, each time a predetermined condition is satisfied.

The processing unit 220 may re-decide the position and the time, at which the moving body moves, each time the moving body departs from the demand position.
The “EaaS system” is a system related to Energy as a Service. The EaaS system is provided as a service related to the provision of various kinds of energy such as power, gas, and renewable energy. For example, the EaaS system provides energy management as a service by using information communication technology. In the present embodiment, a service related to electrical energy is described as an example of “energy”, but the “energy” is not limited to electrical energy and may include any energy.
The MaaS system is a system related to Mobility as a Service.

The eMaaS system provides a service of fusing Eaas and Maas. For example, the eMaaS system provides integrated services which optimize mobility and energy. For example, the eMaaS system is for arbitrating the Eaas system and the Maas system to optimize the whole including the energy service provided by the Eaas system and the mobility service provided by the Maas system to provide a service. For example, a dispatch plan prepared by the MaaS system and an energy plan by the EaaS system are fused to provide a service which minimizes the amount of power consumption, an environmental load, and the like as a whole system.
A flow of processing of each unit will be described with reference to
The processing of the EaaS system illustrated in
In S3012, the energy management system prepares an energy plan for the next day. For example, the energy management system prepares an energy plan in each of the base 10 and the stores 11 to 14. The energy plan includes a power generation amount, a power storage amount, and power consumption for each time zone in one day. The energy plan is, for example, an energy plan for the next day. The energy plan determines how much power is generated, how much power is consumed, how much the stationary battery is charged, or how much the stationary battery is discharged in each of the base 10 and the stores 11 to 14 in each time zone. The power generation amount for each time zone on the next day may be predicted from environmental information such as weather information for the next day and past performance data. The energy plan may indicate in which time zone the suppression (peak cut) of the power consumption is executed in each of the base 10 and the stores 11 to 14. The energy plan may indicate how much power is received in each of the base 10 and the stores 11 to 14 from the outside in which time zone.
The energy management system may prepare an optimal energy plan in each of the base and the stores 11 to 14. For example, the energy management system may prepare the energy plan such that the amount of power received from the grid at each of the base 10 and the stores 11 to 14 is minimized. The energy management system may prepare the energy plan such that the amount of money imposed as a consideration for receiving power from the grid in each of the base and the stores 11 to 14 is minimized. The energy management system may prepare the energy plan such that the amount of money obtained as a consideration for supplying power to the grid in each of the base 10 and the stores 11 to 14 is maximized. In this manner, the energy management system prepares the optimal energy plan as an energy plan for the next day on the basis of the constraint condition. The energy plan determines the amount of power that needs to be received from the outside in each time zone of the next day. As will be described later, the amount of power that needs to be received from the outside can be supplied from a traveling battery included in the vehicle 110. The energy management system transmits the energy plan to a dispatch system of the eMaaS system.
The dispatch system is a system that manages the dispatch of the vehicle 110. The dispatch system is specifically provided by the vehicle control device 60. A “user” in the MaaS system is a user of the dispatch system. For example, the “user” is a person, a system, or the like that inputs delivery demand data in a delivery company. In S3210, the user inputs constraint conditions for dispatch. The constraint conditions for dispatch may include constraints needed to satisfy delivery demands. The constraint conditions for dispatch are constraint conditions for preparing the dispatch plan. The constraint conditions for dispatch include, for example, a delivery source and a delivery destination, a departure time and a return time, a type of an item as a load, a volume of the item, a weight of the item, and the like. Depending on the delivery source and the delivery destination, it is determined from which place to which place the vehicle needs to be operated. From the departure time and the return time, it is determined from which place and at which time the vehicle needs to depart and to which place and at which time the vehicle needs to return. The departure time may be a time at which the vehicle departs from the base 10, and the return time may be a time at which the vehicle returns to the base 10. A time width which allows a change may be set to the departure time and the return time. The type, volume, and weight of the item determine which vehicle can deliver the item.
In S3212, the dispatch system prepares a delivery plan for the next day on the basis of the constraint conditions notified from the user. For example, the dispatch system decides the number of vehicles 110 to be used for delivery, the departure time and the arrival time of the vehicle 110 to be used for delivery, the base 10, and the stores 11 to 14, the traveling route of the vehicle 110, the traveling speed of the vehicle 110, and the stand, on which supplementary charging needs to be performed, among the stands 71 to 74 such that the delivery demand defined by the constraint conditions is satisfied. The dispatch system transmits the dispatch plan to the eMaaS system.
The eMaaS system is a system which includes an arbitration system. The arbitration system is, for example, a system provided by the integrated control device 50. In S3110, the arbitration system receives the energy plan transmitted from the energy management system and the dispatch plan transmitted from the dispatch system.
In S3112, the arbitration system arbitrates the energy plan and the dispatch plan. For example, the arbitration system determines whether the energy plan is satisfied when the vehicle is dispatched according to the dispatch plan. For example, a period in which the vehicle 110 is predicted to be present in the base 10 and the stores 11 to 14 is determined from the dispatch plan. In the period in which the vehicle 110 is present in the base 10 and the stores 11 to 14, when the stores 11 to 14 can receive the power, which needs to be supplied from the outside, from the traveling battery included in the vehicle 110 in a necessary time zone, the arbitration system determines that the energy plan is satisfied. In addition, the arbitration system determines that in the stores 11 to 14 of the movement destination of the vehicle 110, the energy plan is satisfied when the power, which needs to be released to the outside by each of the stores 11 to 14, can be supplied to the traveling battery included in the vehicle 110 in a time zone in which it is necessary to release the power.
When determining that it is not possible to satisfy the energy plan when the vehicle is dispatched according to the dispatch plan, the arbitration system determines how to modify the energy plan to satisfy the dispatch plan. For example, the arbitration system determines how much power consumption in each time zone is to be changed with respect to the energy plan in each of the base 10 and the stores 11 to 14. In addition, the arbitration system determines how much the amount of power received from the grid in each time zone is to be changed in each of the base 10 and the stores 11 to 14. The arbitration system determines how much the amount of power released to the grid in each time zone is to be changed in each of the base 10 and the stores 11 to 14.
In addition, when determining that it is not possible to satisfy the energy plan when the vehicle is dispatched according to the dispatch plan, the arbitration system determines how to modify the dispatch plan to satisfy the energy plan. For example, the arbitration system determines how much the departure time and the return time are to be changed with respect to the dispatch plan received from the dispatch system in each of the base 10 and the stores 11 to 14. In addition, with respect to the dispatch plan, the arbitration system determines how to modify the traveling route of the vehicle 110. In addition, with respect to the dispatch plan, the arbitration system determines how many vehicles 110 to be used for delivery are to be modified. In addition, with respect to the dispatch plan, the arbitration system determines at which stand of the stands 71 to 74 and at which time supplementary charging is to be performed. In addition, with respect to the dispatch plan, the arbitration system determines how much the traveling speed of the vehicle 110 is to be modified.
In addition, when determining that it is not possible to satisfy the energy plan when the vehicle is dispatched according to the dispatch plan, the arbitration system determines how to modify both the energy plan and the dispatch plan such that the dispatch plan and the energy plan after the modification can be satisfied. As described above, the arbitration system determines how to modify the power consumption in each time zone in each of the base 10 and the stores 11 to 14, the amount of power received from the grid in each time zone, and the amount of power released to the grid in each time zone, and how to modify the departure time, the return time, the traveling route, the traveling speed, the number of the vehicles 110 to be used for delivery, and the stand which performs supplementary charging.
In S3112, the arbitration system transmits, to the energy management system and the arbitration system, an arbitration proposal including modification to the energy plan and the dispatch plan. When receiving the arbitration proposal from the arbitration system, in S3014, the energy management system reflects the arbitration proposal, which is received from the arbitration system, in the energy plan prepared in S3012. For example, with respect to the energy plan, the energy management system modifies the power consumption in each time zone in each of the base 10 and the stores 11 to 14, the amount of power received from the grid in each time zone, the amount of power released to the grid in each time zone, and the like according to the arbitration proposal. When the energy management system determines that the energy management in the base 10 and the stores 11 to 14 can be realized according to the arbitration proposal, the energy management system transmits, to the arbitration system, the energy plan reflecting the arbitration proposal as a reflection result.
Similarly, when receiving the arbitration proposal from the arbitration system, in S3214, the dispatch system reflects the arbitration proposal, which is received from the arbitration system, in the dispatch plan prepared in S3212. For example, with respect to the dispatch plan, the dispatch system modifies the departure time, the return time, the traveling route, the traveling speed, the number of the vehicles 110 to be used for delivery, the stand which performs supplementary charging, and the like according to the arbitration proposal. When determining that the delivery demand is satisfied in accordance with the arbitration proposal, the dispatch system transmits, to the arbitration system, the dispatch plan reflecting the arbitration proposal as a reflection result.
In S3114, when the reflection result of the arbitration proposal is received from the energy management system and the dispatch system, the arbitration system checks that the delivery demand and the power demand are satisfied by the energy plan and the dispatch plan in which the arbitration proposal is reflected. When it is checked that the dispatch demand and the power demand are satisfied, the EaaS system transmits, to the EaaS system and the dispatch system, an arbitration result that the plan is executed according to the reflection result of the arbitration proposal. Note that when the delivery demand and the power demand are not satisfied by the energy plan and the dispatch plan reflecting the arbitration proposal, the arbitration system may further modify the energy plan and the dispatch plan and transmit it as an arbitration result. The EaaS system, the dispatch system, and the EaaS system may repeat the processing of S3112, S3014, S3214, and S3114 until the delivery demand and the power demand are satisfied.
When receiving the arbitration result from the arbitration system, the energy management system confirms the energy plan in S3014, and notifies the user of the confirmed energy plan. In S3016, the user executes energy management according to the notified energy plan. In S3018, the user performs performance processing related to the execution of the energy plan. For example, the user performs processing of collecting and inputting the performance data of energy management including the performance data of the charge/discharge amount of the stationary battery, the performance data of the power generation, and the performance data of the power consumption amount in each time zone. In S3020, the energy management system manages the performance data, which is input from each of the users, as history information. Note that the energy management system may use the history information managed by the energy management system when the energy plan is prepared later.
When receiving the arbitration result from the arbitration system, in S3214, the dispatch system confirms the dispatch plan and notifies the user of the confirmed dispatch plan. In S3216, the user executes the plan according to the notified dispatch plan. In S3218, the user performs performance processing related to the execution of the dispatch plan. For example, the user includes processing of collecting and inputting travel performance data including the travel data of each vehicle 110, the remaining capacity of a traveling battery, and the like. In S3020, the dispatch system manages, as history information, the travel performance data input from the user. Note that the dispatch system may use the history information managed by the dispatch system when the dispatch plan is prepared later.
In S304, the vehicle control device 60 transmits, to the integrated control device 50, the delivery schedule information of items to the stores 11 to 14 on the next day. For example, the vehicle control device 60 makes a still picture of the delivery information on the basis of the delivery request of the product of the next day acquired from each of the stores 11 to 14. Specifically, the vehicle control device 60 acquires, as the delivery request, the information of the items to be delivered on the next day and information for identifying a delivery destination store. The information of the items includes a quantity of items to be delivered to each store, weight information of each item, delivery time information indicating a time at which the store desires delivery, and the like. In addition, the vehicle control device 60 manages vehicle information including the number of the vehicles 110 and the current remaining capacity of the traveling battery included in the vehicle 110. The vehicle control device 60 transmits, to the integrated control device 50, the delivery information including the next day delivery schedule information and the vehicle information.
In S306, the processing unit 220 performs processing related to the operation control of the vehicle 110 and the control of the power control devices 41 to 44 on the basis of the delivery information and the power demand information. For example, the processing unit 220 generates operation information including a position and time at which the vehicle 110 moves between the stores 11 to 14 and the traveling route of the vehicle 110. In addition, for the base 10 and the stores 11 to 14, the processing unit 220 generates the information of the power transmission/reception performed between the traveling battery of the vehicle 110 and the base 10 and the stores 11 to 14. The power transmission/reception information includes, for example, a time for performing the power transmission/reception and a power transmission/reception amount. The processing of S306 will be described later. In S308, the processing unit 220 transmits the power transmission/reception information to the power control devices 40 to 44. Note that the processing unit 220 transmits, to the power control devices 40 to 44 of the base 10 and the stores 11 to 14 for which the power transmission/reception is decided not to perform, approval information indicating that the control based on the power demand information generated by each of the power control devices 40 to 44 is approved. In S310, the processing unit 220 transmits the operation information to the vehicle control device 60.
In S312, the power control devices 40 to 44 start power control in the base 10 and the stores 11 to 14, respectively. In S314, the vehicle control device 60 starts the operation control of the vehicle 110 according to the operation information. For example, the vehicle control device 60 instructs a driver of the vehicle 110 in the base 10 to cause the vehicle 110 to depart from the base 10 according to the operation information.
In S320, when the vehicle 110 arrives at the store 11, the processing unit 220 determines that the vehicle 110 arrives at the store 11 from the position information based on a GPS signal transmitted from the vehicle 110. In S322, the processing unit 220 communicates with the vehicle 110 and receives the remaining amount of the traveling battery of the vehicle 110. In S330, the processing unit 220 corrects the operation information of the vehicle 110 and the power transmission/reception information in the base 10 and the stores 11 to 14 on the basis of the weather forecast information predicted at the present time and the remaining battery amount information of the vehicle 110. The specific processing of S330 will be described later. In S332, the processing unit 220 transmits the corrected power transmission/reception information to the power control devices 40 to 44. In S334, the processing unit 220 transmits the operation information to the vehicle control device 60. Note that each time the vehicle 110 arrives at the stores 11 to 14, the processing similar to the processing from S320 to S334 is repeated. Accordingly, the power transmission/reception information and the operation information can be updated on the basis of the latest information.
When deciding the operation information, the processing unit 220 refers to the delivery information to decide the traveling route and the vehicle speed on which and at which the vehicle 110 travels between each base 10 and the stores 11 to 14 such that the delivery schedule information is satisfied and the power consumption necessary for traveling of the vehicle 110 on the next day is minimized. As an example, on the basis of traffic congestion information of a road, gradient information of a road, signal information, and the like predicted on the next day, the processing unit 220 may decide the traveling route and the vehicle speed for traveling on the traveling route such that the power consumption necessary for traveling of the vehicle 110 is minimized. When the processing unit 220 transmits, to the vehicle control device 60, the operation information including the traveling route and the vehicle speed information, the vehicle control device 60 instructs the driver of the vehicle 110 through a navigation device included in the vehicle 110 such that the vehicle 110 travels according to the traveling route and the vehicle speed information.
As a part of the power management, the power control devices 40 to 44 charge the stationary batteries 30 to 34 with surplus power when the power generation exceeds the power consumption, and cause the stationary batteries 30 to 34 to be discharged to cover at least a part of the power consumption when the power consumption exceeds the power generation. Accordingly, the power control devices 40 to 44 perform control to perform a peak shift of the power consumption.
In the stationary batteries 30 to 34, a threshold as a lower limit value of the remaining battery amount is set in advance. The power control devices 40 to 44 restrict the discharge of the stationary batteries 30 to 34 so that the remaining battery amount does not fall below a preset threshold. A line 630 in
For example, when the power consumption, the power generation, and the remaining battery amount are predicted as illustrated in
In addition, when the power amount of the stationary battery 33 is predicted to be insufficient also in the store 13, while supplementary charging is performed on the traveling battery at the stand 72 on the way traveling from the store 12 to the store 13, and an item to be handed over to the store 13 is unloaded from the vehicle 110 after arrival at the store 13, the processing unit 220 decides the operation information such that the traveling battery included in the vehicle 110 is discharged to be able to supply power to the store 13. In addition, when it is predicted that the power becomes excessive in the store 14, while an item to be handed over to the store 14 is unloaded from the vehicle 110 after arrival at the store 14, the processing unit 220 supplementarily charges the traveling battery with the power supplied from the power generation device 24 or the stationary battery 34 of the store 14.
The processing unit 220 refers to the delivery information to decide the operation information including the traveling route and the vehicle speed of the vehicle 110, the departure time from the base 10, the arrival time to each store of the stores 11 to 14, the departure time from each store, and the arrival time to the base 10 such that the time when each of the stores 11 to 14 desires the delivery of items is satisfied, and the amount of power necessary for traveling of the vehicle 110 is minimized. At this time, on the basis of infrastructure information including traffic jam forecast information, the processing unit 220 decides the operation information such that the amount of power necessary for traveling of the vehicle 110 is minimized.
In S820, on the basis of the amount of power necessary for the vehicle 110 to travel according to the operation information and the power demand information, the processing unit 220 decides a stand and a store for performing supplementary charging on the traveling battery, a supplementary charging power amount, and a store for discharging the traveling battery and a discharging power amount. For example, the time when the vehicle 110 is predicted to stop at each of the stores 11 to 14 is determined from the operation information. In addition, from the power demand information, it is determined whether the excess of power is generated or the power is insufficient at the time when the vehicle 110 is predicted to stop at each of the stores 11 to 14. In this regard, when the power becomes excessive while the vehicle 110 stops at each of the stores 11 to 14 within the time when the vehicle 110 is predicted to stop at each of the stores 11 to 14, the processing unit 220 determines that supplementary charging is possible while the vehicle stops at each of the stores 11 to 14. In addition, on the basis of the traveling route of vehicle 110 and the positions where the stand 71 to the stand 74 are installed, the processing unit 220 determines that supplementary charging is possible at the stands 71 to 74 when the stands 71 to 74 are installed within a predetermined distance from the traveling route.

Processing similar to the processing described with reference to
Note that the processing in a case where the vehicle 110 arrives at the stores 11 to 14 has been described with reference to S330 of
In the second embodiment, on the basis of the delivery information and the power demand information, the processing unit 220 decides operation information and power transmission/reception information in which the vehicle 110a departs from the base 10 and then returns to the base 10 via the store 11 and the store 12. In addition, until the vehicle 110a returns to the base 10 after the vehicle 110a departs from the base 10, on the basis of the delivery information and the power demand information, the processing unit 220 decides operation information and power transmission/reception information in which the vehicle 110b departs from the base 10 and returns to the base 10 via the store 13 and the store 14. Note that, in the second embodiment, instead of the determination that the operation is performed in the order of the base 10, the store 11, the store 12, the store 13, the store 14, and the base 10 in the first embodiment, the processing unit 220 may perform processing of independently deciding the operation information and the power transmission/reception information on the assumption that it is determined that the operation is performed in the order of the base 10, the store 11, the store 12, and the base 10 and the operation is performed in the order of the base 10, the store 13, the store 14, and the base 10.
Note that, in the second embodiment, the processing unit 220 may generate operation information and power transmission/reception information in which the vehicle 110a departs from the base 10 and then arrives at the store 11, departs from the store 11 and then returns to the base 10 without passing through other stores 12 to 14, departs from the base 10 and then arrives at the store 12, and departs from the store 12 and then returns to the base 10 without passing through other stores 13 and 14.
The second embodiment may be an embodiment applied when the operation information and the power transmission/reception information that satisfy the delivery information and the power demand cannot be decided by the processing described in connection with the first embodiment. According to the second embodiment, it is possible to flexibly respond to a delivery request to each of the stores 11 to 14 and a power demand request.
In the first embodiment and the second embodiment, an aspect may be adopted in which the processing unit 220 decides the operation information and the power transmission/reception information by giving priority to the power demand in each of the stores 11 to 14 over the delivery demand in each of the stores 11 to 14. For example, the processing unit 220 may decide operation information and power transmission/reception information for minimizing the amount of power necessary for the vehicle 110 to travel and the amount of power received from the grid by each of the stores 11 to 14 in each of the stores 11 to 14, and confirm the operation information and the power transmission/reception information when the delivery information can be satisfied by the operation information. Note that when the delivery information cannot be satisfied by the operation information and the power transmission/reception information, the processing unit 220 may decide the operation information and the power transmission/reception information for minimizing the amount of power for the vehicle 110 to travel and the amount of power received from the grid by each of the stores 11 to 14 in each of the stores 11 to 14 within a range at least satisfying the delivery information. When both the delivery information and the power demand cannot be satisfied, the processing unit 220 may decide the operation information and the power transmission/reception information to satisfy the delivery information in the stores 11 to 14 and satisfy the power demand of some predetermined stores among the stores 11 to 14. In addition, when both the delivery information and the power demand cannot be satisfied, the processing unit 220 may decide the operation information and the power transmission/reception information to satisfy the delivery information of some predetermined stores among the stores 11 to 14 within a range of satisfying at least the power demand of the stores 11 to 14. When both the delivery information and the power demand cannot be satisfied, the processing unit 220 may decide the operation information and the power transmission/reception information to satisfy at least the delivery demand and the power demand of some predetermined stores among the stores 11 to 14. Note that the some predetermined stores among the stores 11 to 14 may be stores which are predetermined to be maintained in an emergency such as a power outage or an earthquake.
In the third embodiment, on the basis of the delivery information and the power demand information, the processing unit 220 decides operation information and power transmission/reception information in which the vehicle 110a departs from the base 10 and then returns to the base 10 via the store 11, the store 12, the store 13, and the store 14. In addition, the processing unit 220 decides operation information and power transmission/reception information in which the vehicle 110b departs from the base 10 and then returns to the base 10 via the store 1214, the store 1213, the store 1212, and the store 1211.
In this case, until the vehicle 110 arrives at the store 14 after the vehicle 110a departs from the base 10, when it is determined from the latest infrastructure information, the traveling battery information of the vehicle 110a, and the like that it is not possible to satisfy at least one of the delivery information or the power demand information for the store 14, the processing unit 220 generates new operation information and power transmission/reception information in which the vehicle 110b departs from the store 1211 and then returns to the base 10 via the store 14. The processing unit 220 may periodically acquire the remaining amount of the traveling battery of the vehicle 110b and, when it is possible to supply power exceeding the power demands of the store 1214, the store 1213, the store 1212, the store 1211, and the base 10, may generate new operation information and power transmission/reception information in which the vehicle returns to the base 10 via the store 14. Accordingly, it is possible to increase a possibility of satisfying the delivery information and the power demand information for the store 14.
As described above, according to the control systems 100 and 1200 according to the above-described embodiments, by using the traveling battery included in the vehicle 110, it is possible to perform energy management in the base 10 and energy management in the stores 11 to 14 while satisfying the delivery demand in the stores 11 to 14 other than the base 10. Accordingly, optimal energy management can be performed in all of the base 10 and the stores 11 to 14.
