A power supply planning device for planning is known (see, for example, Patent Document 1).

JP-A-2017-103938

In the technique described in Patent Document 1 described above, based on vehicle position information, stored power information, information on equipment that can charge the vehicle, information on equipment that requires power, and information on routes between each equipment, Vehicle movement plans and power transfer plans are drafted.

When connecting a storage battery installed in a moving body such as a vehicle to a facility subject to power supply, power supply equipment such as a power converter is used to match the output of the storage battery to the voltage type and voltage class of the facility subject to power supply. Be done.

On the other hand, the number of these power supply facilities is limited in the power supply target facilities. For this reason, for example, when there are a large number of vehicles that supply power to the power supply target facility, the storage battery is charged at a charging facility in another location rather than directly heading to the power supply target facility, and then the power supply target. It may be possible to supply power more efficiently by moving to a facility and supplying power.

Alternatively, considering the power consumed when moving to the power supply target facility via a charging facility in another location, it is better to go directly to the power supply target facility and supply power without charging. It is also assumed that power can be supplied efficiently. That is, the vehicle movement plan for efficient power supply may differ depending on the conditions of the power supply target facility and the charging facility.

On the other hand, in the above-mentioned conventional technology, the power transfer plan is not formulated in consideration of the above situation. Therefore, depending on the situation, the power supply plan for efficient power supply may not be formulated. There was a problem that there was.

The present disclosure has been made in order to solve the above-mentioned problems, and an object of the present disclosure is to provide a power supply plan management device capable of making a more efficient power supply plan.

To achieve the above object, the present disclosure provides the following means.

A power supply plan management device that formulates a plan, and a first estimation unit that estimates the first time, which is the end of the power supply available period of the power supply unit that is installed in the power supply target facility and supplies power. The second time, which is a time before the first time, and the second time, when the moving body that is not supplying power can supply power to the power supply target facility without charging. The second estimation unit that estimates the second electricity storage amount remaining in the power storage unit and the moving body charge at a charging candidate point at a position different from the power supply target facility, arrive at the power supply target facility, and receive electric power. A third estimation unit that estimates the amount of electricity stored in the storage unit at the third time, which is a time before the first time, and the third time, which is in a supplyable state, and the above. A determination unit is provided to compare the second electricity storage amount and the third electricity storage amount and determine the magnitude of the electricity storage amount remaining in the electricity storage unit.

According to the power supply plan management device according to the present disclosure, the second estimation unit remains in the power storage unit when the mobile body moves to the power supply target facility within the power supply target facility of the power supply unit without charging. Estimate the amount of electricity stored. In addition, the third estimation unit determines the amount of electricity stored in the power storage unit when the mobile body moves to the power supply target facility within the period in which the power supply unit can supply power after charging at the charging candidate point. presume. Then, the determination unit compares each estimated storage amount and determines the magnitude thereof.

By doing so, either the case of going directly to the power supply target facility without charging or the case of charging at a charging candidate point at a position different from the power supply target facility and then heading to the power supply target facility. However, it is determined whether the amount of electricity stored in the electricity storage unit increases. Therefore, based on this determination result, it is possible to formulate an efficient power supply plan when power is supplied to the power supply target facility using a moving body such as a vehicle.

In the above, the power supply plan management device is further provided with a determination unit for determining a movement route of the mobile body toward the power supply target facility, and the second estimation unit includes the second storage amount and the second storage amount. The standard route information including the route information used when estimating the second stored amount is estimated, and the third estimation unit is used when estimating the third stored amount and the third stored amount. It is preferable that the replenishment route information including the information of the existing route is estimated, and the determination unit determines the movement route based on the determination result by the determination unit, the standard route information, and the replenishment route information.

By doing so, the movement route of the moving body is determined based on the determination result by the determination unit, the standard route information, and the supply route information.

In the above, the determination unit is in a state where the mobile body can supply electric power to the power supply target facility based on the determination result by the determination unit, the standard route information, and the supply route information. It is preferable to determine the movement route that maximizes at least one of the amount of electricity stored in the electricity storage unit and the electric power that can be supplied by the electricity storage unit.

By doing so, when the mobile body arrives at the facility to be fed, the determination unit has a movement path in which at least one of the amount of electricity remaining in the electricity storage unit and the electric power that can be supplied by the electricity storage unit is maximized. To determine. Therefore, it is possible to formulate an efficient power supply plan (movement path of the mobile body) capable of supplying a larger amount of electric power and the amount of electric power to the facility to be supplied with electric power.

In the above, the power supply plan management device further includes a fourth estimation unit that estimates the power required by the power supply target facility at a predetermined time and the amount of power, and the determination unit is such that the moving body feeds the power. The difference between the amount of power required by the power supply target facility and the amount of power stored remaining in the power storage unit when the target facility can be supplied with power, and the power required by the power supply target facility and the power storage The movement path is determined so that at least one difference from the electric power that can be supplied by the unit is the smallest.

By doing so, the fourth estimation unit determines the amount of power required by the power supply target facility when the mobile body arrives at the power supply target facility and is ready to supply power, and the power required at that time. To estimate. Then, the determination unit determines the movement path that minimizes the difference between the estimated electric power and the amount of electric power remaining in the electric power storage unit, or at least one of the difference between the estimated electric power and the electric power that can be supplied by the electric power storage unit. decide.

Therefore, when the mobile body arrives at the facility to be supplied with power, it is possible to formulate an efficient power supply plan (movement route of the mobile body) capable of supplying electric power with high power supply efficiency.

According to the power supply plan management device according to the present disclosure, there is an effect that it is possible to formulate an efficient power supply plan when power is supplied to the power supply target facility by using a mobile body.

Further, the fourth estimation unit 14 performs a process of estimating the required electric energy at a predetermined time based on the equipment information acquired by the equipment information acquisition unit 19 (S25A). In the present embodiment, the fourth estimation unit 14 determines the power receiving devices 24a to 24c based on the load information (power consumption) of the power supply target facility 2, the power that can be supplied by the power supply unit 23, and the amount of power remaining in the power supply unit 23.

Specifically, the fourth estimation unit 14 applies to an example in which the usage status of the power receiving devices 24a to 24c of the power supply target facility 2 is estimated and the required power amount of the power supply target facility 2 is estimated as follows. Then, the following explanation will be given.

(1) at time _{T 5a} time before, the power receiving device 24a~24c each vehicle 27a, 27b, 27c are connected.
By (2) battery of the vehicle 27a is minimized volume, is released connection between the power receiving device 24a at time T _5a, the power receiving device 24a is in a state available at time T _5a later time.
(3) Since _{the storage battery of the vehicle 27b has reached the minimum capacity at time T 5b} , the connection with the power receiving device 24b is disconnected, and the power receiving devices 24a and 24b become available at the time after _{time T 5b.} ..

Then, based on the above estimation, the fourth estimation unit 14 estimates the required power amount of the power supply target facility 2 as follows (see FIG. 7A).
(1) The required power amount at the time before the _{time T 5a is 0.}
(2) At the time _{between the time T 5a} and the time T _5b , the required electric energy is W _5a .
(3) At a time _{after the time T 5b} , the required electric energy is W _5b .

The respective arrival times T _2a , T _3b , T _3c , the stored amount W _2a , the stored amount W _3b , and the stored amount W _3c are estimated, and further, the determination process by the determination unit 17 and the estimation process by the fourth estimation unit 14 are performed. Then, the determination unit 20A performs a process of determining the movement route of the vehicle 3.

Specifically determination unit 20A, each of the arrival time _{T 2a,} T _3b, the storage amount _{W 2a} in _{T 3c,} the storage amount _{W 3b,} a storage amount _{W 3c,} each arrival time _{T 2a,} T _3b, in _{T 3c} A process of comparing the required power amounts is performed (S55A). Then, a process is performed in which the route in which the difference between the amount of electricity stored in the electricity storage unit 31 remaining in the electricity storage unit 31 at each time and the amount of required electric power is the smallest is determined as the movement route of the vehicle 3 (S60A).

A determination unit 20A performs the specifically described, in the arrival time _{T 2a,} the difference _{W g2a} of the charged amount and the required amount of _{power, W g2a} = estimated to be "charged amount _{W 2a".} Further, the determination unit 20A _{estimates that at the arrival time T 3b , the difference W g3b} between the stored amount and the required power amount is W _g3b = "stored amount W _3b -required power amount W _5a ". Further, the determination unit 20A _{estimates that the difference W g3c} between the stored amount and the required power amount is W _g3c = "stored amount W _3c -required power amount W _5b " at _{the arrival time T 3c.}

Then, the determination unit 20A compares the differences between them, determines that the "storage amount W _3c -required power amount W _5b " is the smallest value, and determines the replenishment route B in that case as the movement route of the vehicle 3. do. Then, the determination unit 20A performs a process of notifying the manager of the power supply plan management device 1A of the supply route information of the supply route B and transmitting the information to the vehicle 3.

According to the power supply plan management device 1 configured as described above, the fourth estimation unit 14 receives the power supply target facility 2 when the vehicle 3 arrives at the power supply target facility 2 and becomes in a state where power can be supplied. Estimate the amount of power required by. Then, the determination unit 20 determines the movement route that minimizes the difference between the estimated electric power amount and the electricity storage amount remaining in the power storage unit 31.

Therefore, when the vehicle 3 arrives at the power supply target facility 2, it is possible to formulate an efficient power supply plan (movement route) capable of supplying power with high power supply efficiency.

That is, even if the vehicle 3 arrives at the power supply target facility 2 and is in a state where power can be supplied, if another storage battery is connected to the power receiving device 24 at that time, the vehicle 3 immediately Power cannot be supplied to the power supply target facility 2. In such a case, for example, the vehicle 3 is moved to another facility that requires power supply, or is charged at another charging facility 5 that has a large amount of rechargeable power in the distance. In some cases, it is possible to supply power more efficiently. That is, by formulating a movement plan of the vehicle 3 in consideration of the required electric energy of the power supply target facility 2, it is possible to formulate a more efficient and flexible power supply plan.

The technical scope of the present disclosure is not limited to the above-described embodiment, and various changes can be made without departing from the spirit of the present disclosure. For example, in the above embodiment, the power supply plan management devices 1 and 1A have been described by applying to an example used for planning a power supply plan using the vehicle 3, but the description is not limited to this. For example, the power supply plan management devices 1, 1A may be used to formulate a power supply plan in which a portable temporary storage battery for temporary use is mounted on a vehicle or the like and moved. Alternatively, the power supply plan management devices 1 and 1A may be used to formulate a power supply plan using another mobile body provided with a storage battery or the like capable of supplying power to the power supply target facility 2.

Further, in the above embodiment, the description has been made by applying to an example in which the power storage unit 31 is charged to its rated capacity W _{max at the charging facility 5.} That is, the description has been made by applying the example in which the third estimation unit 13 estimates the charging time t _c required when the power storage unit 31 is charged to its rated capacity W _{max at the charging facility 5.} On the other hand, the power storage unit 31 does not have to be charged to _{its rated capacity W max at the charging facility 5.} That is, the third estimation unit 13 estimates the charging time t _{c at} which the storage amount W _{3 at the arrival time T 3} is maximum, or the difference from the storage amount remaining in the storage unit 31 at the time of return. It may be configured to estimate the _{charging time t c} so as to be the minimum. In this way, it becomes possible to formulate a more diverse and efficient power supply plan.

Alternatively, the fourth estimation unit 14 estimates the power (required power) that the power supply target facility 2 can accept at a predetermined time, and the determination unit 20A determines the power that can be supplied by the power storage unit 31 and the fourth estimation unit 14. The process of determining the movement route may be performed by estimating the difference in the required power estimated by.

Alternatively, the fourth estimation unit 14 estimates the required power amount and the required power of the power supply target facility 2 at a predetermined time, the determination unit 20A determines the power that can be supplied by the power storage unit 31, and the fourth estimation unit 14 The process of determining the path when at least one of the estimated difference in required power or the difference between the remaining power amount and the required power amount of the power storage unit 31 is the minimum may be performed as a moving path.

In this way, when the vehicle 3 arrives at the power supply target facility 2 and becomes in a state where power can be supplied, the magnitude of the power that can be supplied by the power storage unit 31 and the required power of the power supply target facility 2 at that time. It is possible to formulate a power supply plan in consideration of. Therefore, it becomes possible to formulate a more efficient and flexible power supply plan.

Alternatively, the process second estimation unit 12, the third estimating unit 13, respectively estimates the SOC of power storage unit 31 of the arrival time _T 2, _{T 3,} the determination unit 17, which compares the magnitude of the estimated SOC You may go. Then, the determination unit 20 may perform a process of determining the movement route based on the determination results of the SOC and the determination unit 17 estimated by the second estimation unit 12 and the third estimation unit 13.

In this way, it is possible to formulate a power supply plan in consideration of the SOC of the power storage unit 31, and it is possible to formulate an efficient and flexible power supply plan.

Further, in the second embodiment described above, the equipment information acquisition unit 19 collects information on other facilities that require power supply, and the fourth estimation unit 14 obtains the required electric energy and electric power of the other facilities. It may be configured to perform the estimation process. Then, the determination unit 20A may perform a process of determining the movement route of the vehicle 3 in consideration of the estimated required electric energy and the required electric power of the other facility.

By doing so, for example, even if the vehicle 3 arrives at the power supply target facility 2 and is in a state where power can be supplied, it seems that the power supply target facility 2 has already received power supply from another vehicle at that time. In some cases, it is possible to formulate a power supply plan such as allocating the vehicle 3 to another facility. That is, it is possible to formulate a power supply plan in consideration of the required power of other facilities.

Further, in the above embodiment, the description has been made by applying the example of determining the movement route of one vehicle 3, but the power supply plan management devices 1 and 1A determine the movement route of the plurality of vehicles 3. You may go. In this way, the vehicle 3 capable of supplying electric power most efficiently can be distributed to the power supply target facility 2, and a more efficient power supply plan can be formulated.

Further, the equipment information acquisition unit 19 collects information on a plurality of other facilities, the fourth estimation unit 14 performs processing for estimating the required electric energy and electric power of those facilities, and the determination unit 20A efficiently. The configuration may be such that a process of determining a combination of the vehicle 3 capable of supplying various electric power and the facility is performed. In this way, it becomes possible to formulate a more efficient power supply plan.

Further, the present invention is not limited to the one applied to the above-described embodiment, and may be applied to an embodiment in which these embodiments are appropriately combined, and the present invention is not particularly limited.
