Abstract

In an EMS server 100 according to the present disclosure, an electric mobility movement formulation unit 103, when it has been determined that a power supply to in-house equipment 200 (power consuming equipment) due to self-consignment of own company power generation equipment 300 is insufficient, detects an electric mobility group 400 (power supplier) on the basis of usage information (operational state) regarding the electric mobility group 400. If there is an electric mobility group 400 that can be used, the electric mobility movement formulation unit 103 compares the movement cost of moving the electric mobility group 400 to the in-house equipment 200 (power consuming equipment) and the purchase cost of purchasing external power by the in-house equipment 200. An electric mobility movement information transmission unit 104 issues a notification for moving the electric mobility group 400 on the basis of the comparison result.

Description

Apparatus and method

[0001] The present invention relates to an apparatus and method for supplying power using electric mobility or the like.

[0002] Currently, electric mobility vehicles such as electric vehicles and electric kick scooters are becoming popular overseas, and it is expected that they will also become popular in Japan in the future. In such a society, it is known to supply electricity stored in electric vehicles to an external source. For example, Patent Document 1 describes a system in which an electric vehicle is parked in a parking space and electricity stored in the battery pack of the electric vehicle is supplied to a building via a discharge station.

[0003] JP 2024-13152 A

[0004] In such a society, it is expected that rental services for electric mobility vehicles will also become widespread. However, there is a problem of how to make effective use of electric mobility vehicles when they are not being used.

[0005] Furthermore, in recent years, electricity prices have risen sharply, making it difficult to balance supply and demand for electricity. To address this issue, there is a system called self-dispatch, which transmits electricity generated from a company's own renewable energy sources via a transmission and distribution network to facilities that consume electricity in other locations. While self-dispatch is less costly than regular electricity charges, when electricity is generated from renewable energy sources, such as solar power generation at a power generation facility, the amount of electricity generated may be less than expected. In such cases, the amount of electricity that was planned to be transmitted may fall short of expectations, and the company must purchase the missing electricity from the power company at a high unit price, which is considered a shortage imbalance.

[0006] Therefore, an object of the present disclosure is to provide an apparatus and method that can efficiently supply power.

[0007] The device disclosed herein includes a status determination unit that determines the power supply status for a power consumption facility; a power supply unit detection unit that detects the power supply unit based on the power supply status and the operating status of a self-propelled power supply unit; a cost comparison unit that compares the travel cost of the detected power supply object traveling to the power consumption facility with the purchase cost of purchasing external power for the power consumption facility; and a movement processing unit that performs processing to move the power supply object to the power consumption facility based on the comparison result by the comparison unit.

[0008] According to the present disclosure, power can be supplied efficiently based on the operating state of the power supplier.

[0010] The present disclosure will be described with reference to the accompanying drawings. Whenever possible, the same parts are designated by the same reference numerals and redundant description will be omitted.

[0011] 1 is a diagram showing a system configuration including an EMS server 100 according to the present disclosure. As shown in the figure, the EMS server 100 according to the present disclosure can be connected to an in-house facility 200, a company's own power generation facility 300, and a management server 400a. The management server 400a manages a fleet of electric mobility vehicles 400.

[0012] In the present disclosure, the EMS server 100 receives information indicating the amount of power generated from the company's own power generation facility 300. This amount of power generated indicates the amount of power that can be supplied to the company facility 200 through self-consignment. The company facility 200 obtains power from the company's own power generation facility 300 through self-consignment. The company's own power generation facility 300 generates power using renewable energy, such as solar power generation, and transmits power to the company facility 200. The amount of power generated transmitted from the company's own power generation facility 300 is self-consignment plan information, which indicates the amount of power generation planned for a predetermined scheduled date (e.g., the same day or the next day). Because the company's own power generation facility 300 generates power using renewable energy, the amount of power generated varies depending on weather and other conditions. The company's own power generation facility 300 generates the self-consignment plan information by predicting the amount of power generation that will be generated depending on weather and other conditions. The self-consignment plan information may be generated by the manager of the company's own power generation facility 300 predicting the amount of power generation for that day based on experience, etc., or by calculating the amount of power generation based on the hours of sunshine based on a weather forecast.

[0013] The electric mobility fleet 400 is made up of electric vehicles and other electrically powered vehicles, and is a self-propelled power supply entity capable of supplying power to other facilities. The management server 400a manages the usage information (dispatch schedule) of the electric mobility fleet 400. The electric mobility fleet 400 is, for example, a company car, a rental car, or the like, and includes at least one vehicle.

[0014] 2 is a diagram showing a specific example of the usage information DB stored in the management server 400a. As shown in the diagram, reservation information and a current location are associated with each electric mobility. The reservation information indicates the reservation status, which indicates whether or not a reservation can be made, including the reserved time period. The current location indicates the location where the electric mobility is waiting, such as the location of a predetermined parking lot, but the management server 400a may also periodically obtain and store the current location of the electric mobility.

[0015] In the present disclosure, when the amount of power generated by the company's power generation facility 300 is equal to or less than a predetermined value, the EMS server 100 causes the electric mobility vehicles 400 with available schedules to supply power to the in-house facility 200 based on the usage information of the electric mobility vehicles 400 stored in the management server 400a. That is, based on the usage information managed by the management server 400a that manages the electric mobility vehicles 400, the EMS server 100 instructs the manager (driver or operation manager) of the electric mobility vehicles 400 with available schedules to move in order to supply power to the in-house facility 200.

[0016] In response to an instruction from the EMS server 100, the electric mobility vehicles 400 move to the in-house facility 200 and function as an auxiliary power source for self-consignment via a charger / discharger. For example, a terminal of an operator / manager of the electric mobility vehicles 400 receives the movement instruction, and the operator instructs each driver of the electric mobility vehicles 400 to move. Note that the electric mobility vehicles 400 and the in-house facility 200 may be managed by the same company, or may be managed by different companies, or may not be managed by different companies.

[0017] Next, the EMS server 100 will be described. Fig. 3 is a block diagram showing the functional configuration of the EMS server 100. As shown in the figure, the EMS server 100 includes a power generation amount receiving unit 101, an electric mobility usage information receiving unit 102, an electric mobility movement planning unit 103, and an electric mobility movement information transmitting unit 104.

[0018] The power generation amount receiving unit 101 is a part that receives self-dispatch plan information indicating power generation amount information from the company's power generation facility 300.

[0019] The electric mobility usage information receiving unit 102 is a part that receives usage information of the electric mobility group 400 from the management server 400a.

[0020] The electric mobility movement planning unit 103 is a unit that plans the movement of the electric mobility vehicles 400 based on the amount of power generated by the company's power generation facility 300 and usage information about the electric mobility vehicles 400. In the present disclosure, movement planning is a process for determining whether or not movement is necessary for the in-house facility 200 to supply power, and is a unit that detects the electric mobility vehicles 400 based on the usage information and calculates the movement cost. The electric mobility movement planning unit 103 stores the locations of the in-house facility 200 and can calculate the movement cost based on the distance from the current location of each electric mobility vehicle in the electric mobility fleet 400 to the location of the in-house facility 200. The electric mobility movement planning unit 103 determines whether or not to move the electric mobility vehicles 400 to the in-house facility 200 to supply power based on the movement cost and the cost of purchasing power shortages (penalty, imbalance fee).

[0021] The electric mobility vehicle movement information transmission unit 104 is a part that notifies the electric mobility vehicle group 400 (management server 400 a ) to move the electric mobility vehicle group 400 to the in-house facility 200 .

[0022] The operation of the EMS server 100 configured as described above will be described. FIG. 4 is a flowchart showing the operation of the EMS server 100 of the present disclosure. The power generation amount receiving unit 101 receives a self-consignment plan including the amount of power generated on a predetermined scheduled date (e.g., the current day or the next day) from the company's power generation facility 300 (S101). Then, the electric mobility travel planner 103 calculates the power shortage due to self-consignment (S102). That is, the electric mobility travel planner 103 calculates the difference by subtracting the amount of power generated by the company's power generation facility 300 from the power consumption (prescribed amount of power) required by the company facility 200. This difference corresponds to the amount of power purchased from a general power company, and the electric mobility travel planner 103 calculates the cost of purchasing the power shortage as a penalty (imbalance fee).

[0023] The electric mobility usage information receiving unit 102 receives electric mobility usage information (information on a predetermined scheduled date) from the management server 400a (S103). In the present disclosure, the electric mobility group 400 is a plurality of electric mobility vehicles (electric cars and other electric vehicles), and the management server 400a manages usage information in which reservation information, which is a reservation time period (or whether or not a reservation is made on a daily basis), is associated with each electric mobility vehicle.

[0024] The electric mobility movement planning unit 103 detects electric mobility vehicles that do not have reservation information for a predetermined scheduled date in the self-consignment plan based on the usage information (S104). Then, the electric mobility movement planning unit 103 calculates the movement cost of the electric mobility vehicle to the in-house facility 200 (S105). For example, the electric mobility movement planning unit 103 calculates the movement cost by multiplying the movement distance from the current location of the electric mobility vehicle to the in-house facility 200 by the electricity cost by the electricity fee.

[0025] The electric mobility movement planner 103 determines whether the movement cost is less than the power purchase cost (S106). If the movement cost is less than the power purchase cost, the electric mobility movement information transmitter 104 transmits a movement instruction to the electric mobility group 400 (management server 400a) to move to the in-house facility 200 (S107). If the movement cost is not less than the power purchase cost, the electric mobility movement planner 103 does not transmit a movement instruction to the electric mobility group 400 (management server 400a) and ends the process (S107).

[0026] In this way, when there is a shortage of power due to self-consignment, the electric mobility group 400 can be used, but the cost of traveling can be taken into consideration. In other words, when there is a cost for traveling to the in-house facility 200 and it is more cost-effective to purchase power from the power company, a cost-efficient response can be achieved by not issuing an instruction to travel the electric mobility. Note that in the present disclosure, there are cases where the electric mobility cannot make up for the entire shortage, but the shortage can be minimized.

[0027] In the above explanation, the predetermined scheduled date is assumed to be the next day or several days later, and the need for a movement instruction can be determined based on the self-consignment plan for that predetermined date and the usage information for that day. Furthermore, if the predetermined date is the current day, the self-consignment plan is received in the morning of that day, and a movement instruction is issued to electric mobility vehicles that do not have reservation information at that time. It is preferable that the electric mobility movement information transmitter 104 registers reservation information in the usage information DB for electric mobility vehicles that have been instructed to move.

[0028] In the present disclosure, the electric mobility travel planner 103 stores the current locations of the electric mobility fleet 400 (obtained from the management server 400a), the locations of the in-house facilities 200, the electricity costs of each electric mobility, and the current electricity rate (amount per kWh when purchased from the power company). The electric mobility travel planner 103 can calculate travel costs using this information. The electric mobility travel planner 103 also stores the current electricity rate (in units of 1 kWh), and can calculate the electricity purchase cost based on the amount of power that is insufficient in the in-house facilities 200.

[0029] Furthermore, the electric mobility movement planner 103 may also take into consideration the following process. That is, the electric mobility movement planner 103 may obtain the remaining amount of power of each electric mobility unit 400, and detect an electric mobility unit that can be moved based on the remaining amount and reservation information. That is, the electric mobility movement planner 103 may detect an electric mobility unit that has no reservation information (or an electric mobility unit that is available in a predetermined time slot) among electric mobility units that have a remaining amount of power equal to or greater than a predetermined value. In this case, the remaining amount information is stored in a usage information DB, and the EMS server 100 obtains it from the usage information DB as usage information.

[0030] In the above disclosure, even if there are multiple electric mobility vehicles in the group 400, they are all located in the same location. However, this is not limited to this. Each electric mobility vehicle may be waiting in a different location. In this case, the electric mobility movement planning unit 103 may store location information for each electric mobility vehicle and calculate the movement cost for each electric mobility vehicle, and the electric mobility movement information transmission unit 104 may select the electric mobility vehicle with the lowest movement cost and transmit a movement instruction to it.

[0031] Next, a second embodiment of the present disclosure will be described. Fig. 5 is a block diagram showing the functional configuration of an EMS server 100a according to the second embodiment of the present disclosure. The EMS server 100a includes an electric power generation amount receiving unit 101, an electric mobility usage information receiving unit 102, an electric mobility travel planner 103a, and an electric mobility travel information transmitter 104. The EMS server 100a differs from the EMS server 100 of the first embodiment in that it includes the electric mobility travel planner 103a. This difference will be described in detail below.

[0032] The electric mobility trip planning unit 103a is a part that calculates the utilization rate of electric mobility vehicles based on utilization information of the electric mobility vehicles and makes utilization plans based on the utilization rate. In the second embodiment, the utilization rate is calculated based on the number m of electric mobility vehicles for which reservation information exists, relative to the total number n of electric mobility vehicles included in the electric mobility group 400. In the present disclosure, "reservation information exists" means that an electric mobility vehicle has been reserved for at least a certain time period on the scheduled date in the utilization information DB.

[0033] 6 is a flowchart showing the operation of the EMS server 100a according to the second embodiment. Steps S101 to S103 are the same as those in the first embodiment. The power generation amount receiving unit 101 receives the power generation amount, which is the self-consignment plan, from the company's own power generation facility 300 (S101). The electric mobility travel planner 103 then calculates the power shortage due to self-consignment (S102). That is, the electric mobility travel planner 103 calculates the difference by subtracting the power generation amount by the company's own power generation facility 300 from the power consumption (prescribed amount of power) required by the company facility 200. This difference corresponds to the amount of power purchased from a general power company, and the electric mobility travel planner 103 calculates the cost of purchasing the power shortage as a penalty.

[0034] The electric mobility usage information receiving unit 102 receives usage information of electric mobility from the electric mobility group 400 (management server 400a) (S103). In the present disclosure, the electric mobility group 400 is a plurality of electric mobility (electric vehicles and other electric vehicles) managed by usage information in which reservation information (reservation time or presence / absence of reservation) is associated with each electric mobility.

[0035] The electric mobility travel planning unit 103a calculates a utilization rate α based on the electric mobility usage information. The utilization rate α indicates the proportion of available electric mobility that does not have reservation information among multiple electric mobility. Available electric mobility is electric mobility that does not have a usage reservation, and the utilization rate indicates the proportion (m / n) of the number m of electric mobility that has reservation information to the total number n of electric mobility.

[0036] Note that the utilization rate is not limited to this, and may be calculated in hourly units. For example, if the business hours of electric mobility vehicles are 8 hours, the number of electric mobility vehicles is n, the cumulative operating hours are 8×n, the reservation time for electric mobility vehicle x1 is 1 hour, the reservation time for electric mobility vehicle x2 is 2 hours, and so on, and the total reservation time for electric mobility vehicles x1 to xn is t hours, the utilization rate can be calculated as t / (8×n).

[0037] The electric mobility travel planning unit 103 determines whether the utilization rate α is less than the threshold value β (S104a). If the utilization rate α is less than the threshold value β, the electric mobility travel planning unit 103 proceeds to step S105. If the utilization rate α is not less than the threshold value β, the electric mobility travel planning unit 103 does not send a travel instruction and ends the process (S108).

[0038] If the utilization rate α is less than the threshold value β, the electric mobility travel planning unit 103 detects electric mobility for which there is no reservation information from the utilization information DB, calculates its travel cost, and issues travel instructions based on the calculated cost (S105 to S108).

[0039] 7 is a conceptual diagram of a shortage imbalance in self-consignment according to the present disclosure. As shown in the figure, the amount of power used by the in-house facility 200 is a fixed value, and the amount of power generated by the in-house power generation facility 300 fluctuates because the facility generates power using solar power or the like. FIG. 7(a) shows a case in which the amount of power generated is less than the amount of power used, indicating that a shortage imbalance has occurred. This shortage imbalance is compensated for by purchasing power from an external source at a high electricity rate.

[0040] 7B is a diagram showing that the power generation shortage is compensated for by the electric mobility group 400. The shortage imbalance is compensated for by the electric mobility group 400. This eliminates the need to pay high electricity charges.

[0041] Next, a description will be given of the operation and effect of the EMS server 100 of the present disclosure. In the EMS server 100 of the present disclosure, when the electric mobility travel planner 103 determines that there will be a shortage of power supply to the in-house equipment 200 (power consumption equipment) due to self-consignment of the in-house power generation equipment 300, the electric mobility travel planner 103 detects the electric mobility group 400 (power supplier) based on usage information (operating status) of the electric mobility group 400.

[0042] When there is an available electric mobility group 400, the electric mobility travel planning unit 103 compares the travel cost of the electric mobility group 400 traveling to the in-house facility 200 (power consuming facility) with the purchase cost of the in-house facility 200 purchasing external electricity.

[0043] Then, the electric mobility vehicle movement information transmission unit 104 issues a notification to move the electric mobility group 400 based on the comparison result.

[0044] This allows power to be supplied from the electric mobility group 400 to the in-house facility 200. Even if there is a power supply shortage due to self-consignment, there is no need to purchase expensive power from a power company. Furthermore, by performing notification control for the movement of the electric mobility group 400, taking into account the travel cost to the in-house facility 200, efficient power supply is possible.

[0045] In the present disclosure, the EMS server 100 includes a power generation amount receiving unit 101 that acquires self-consignment plan information indicating the amount of power generated. The power generation amount receiving unit 101 functions as a power generation amount acquiring unit. Then, the electric mobility movement planning unit 103 determines, based on the self-consignment plan information, that there will be a shortage of power supply to the in-house facility 200 due to self-consignment.

[0046] In the present disclosure, renewable energy obtained from solar power generation or the like is used, and the amount of power generated is not necessarily stable. Therefore, the EMS server 100 can determine the shortage of power supply to the in-house equipment 200 by receiving the self-consignment plan information.

[0047] In the present disclosure, the EMS server 100 also includes an electric mobility usage information receiving unit 102 that acquires usage information indicating the operating status (reservation information) of the electric mobility fleet 400. The electric mobility usage information receiving unit 102 functions as an operating status acquiring unit. The electric mobility trip planning unit 103 detects the electric mobility fleet 400 based on the reservation information.

[0048] In the present disclosure, reservation information indicating the planned use of the electric mobility vehicles 400 in the EMS server 100 is treated as an operating status, and this is used to select the electric mobility vehicles 400. In the present disclosure, for example, the electric mobility vehicles 400 are rental cars, which are multiple electric vehicles. Based on the rental car reservation information, it is possible to determine whether or not the electric mobility vehicles 400 can travel to the in-house facilities 200 to compensate for the power shortage. Therefore, by using an available electric mobility vehicle 400, efficient compensation work is possible. Note that in the present disclosure, the operating status refers to a reservation, but may also include an actual operating status.

[0049] Furthermore, when there are multiple electric mobility vehicles in the fleet 400, the electric mobility movement planning unit 103 determines whether there is an available electric mobility vehicle in the fleet 400 based on their utilization rate (scheduled operation rate). For example, if the electric mobility vehicle fleet 400 consists of 100 electric mobility vehicles and 30 electric mobility vehicles have reservations, the electric mobility movement planning unit 103 determines that the utilization rate is 30%. If the threshold is set to 50%, and the utilization rate is lower than 50%, it can be determined that there is sufficient operating capacity even if the in-house equipment 200 is used to make up for the shortage. In such a case, a notification is issued to move the electric mobility vehicle fleet 400.

[0050] This makes it possible to replenish the in-house equipment 200 with electricity depending on the operating status of the electric mobility group 400.

[0051] In the present disclosure, the travel cost is calculated based on the distance traveled by the electric mobility fleet 400 to the in-house facility 200, the electricity cost of the electric mobility fleet 400, and the electricity rate per unit.

[0052] This allows accurate movement costs to be calculated. However, it is not necessary to calculate precise movement costs, and a rough specified value may be used.

[0053] The device and method of the present disclosure have the following configuration.

[0054] [1] An apparatus comprising: a state determination unit that determines the power supply status for a power consumption facility; a power supply body detection unit that detects the power supply body based on the power supply status and the operating status of a self-propelled power supply body; a cost comparison unit that compares the movement cost of the detected power supply object moving to the power consumption facility with the purchase cost of purchasing external power for the power consumption facility; and a movement processing unit that performs processing to move the power supply object to the power consumption facility based on the comparison result by the comparison unit.

[0062] The block diagrams used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of hardware and / or software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are connected directly or indirectly (e.g., via wire, wirelessly, etc.) and these multiple devices. The functional block may also be realized by combining the single device or multiple devices with software.

For example, a functional block (component) that performs transmission is called a transmitting unit or transmitter. As mentioned above, there are no particular limitations on how these functions are implemented.

[0064] For example, the EMS server 100 according to an embodiment of the present disclosure may function as a computer that performs processing of the electric mobility management method of the present disclosure. Fig. 8 is a diagram illustrating an example of the hardware configuration of the EMS server 100 according to an embodiment of the present disclosure. The above-described EMS server 100 may be physically configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, and the like.

[0065] In the following description, the term "device" can be interpreted as a circuit, a device, a unit, etc. The hardware configuration of the EMS server 100 may be configured to include one or more of the devices shown in the figure, or may be configured to exclude some of the devices.

[0066] Each function of the EMS server 100 is realized by loading specific software (programs) onto hardware such as the processor 1001 and memory 1002, causing the processor 1001 to perform calculations, control communication via the communication device 1004, and control at least one of reading and writing data in the memory 1002 and storage 1003.

[0067] The processor 1001 controls the entire computer by running, for example, an operating system. The processor 1001 may be configured by a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic unit, a register, etc. For example, the electric mobility travel planner 103 described above may be realized by the processor 1001.

[0068] The processor 1001 also reads programs (program codes), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002 and executes various processes in accordance with these. The programs used are those that cause a computer to execute at least some of the operations described in the above-described embodiments. For example, the electric mobility travel planning unit 103 may be implemented by a control program stored in the memory 1002 and running on the processor 1001, and similar implementations may be made for other functional blocks. While the above-described various processes have been described as being executed by one processor 1001, they may also be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may be implemented by one or more chips. The programs may also be transmitted from a network via a telecommunications line.
