The third charge/discharge management system 33 is operated by the manager of the airport parking lot 43 as a consumer. The airport parking lot 43 is, for example, a parking lot at the airport or in the vicinity of the airport. The parking lot in the vicinity of the airport is, for example, an outdoor parking lot near the airport or a hotel parking lot near the airport. The airport parking lot 43 is equipped with charging/discharging equipment for charging/discharging one or more vehicles parked in the airport parking lot 43. The third charge/discharge management system 33 manages the charging/discharging equipment installed in the airport parking lot 43. In this embodiment, the third charge/discharge management system 33 transmits data indicating the usage status of the charging/discharging equipment installed in the airport parking lot 43 to the aggregation support device 20. The aggregation support device 20 calculates the actual usage rate of the charging/discharging equipment in the airport parking lot 43 as the operation rate of the airport parking lot 43 based on the data transmitted from the third charge/discharge management system 33 as an external system. The aggregation support device 20 acquires the obtained calculation result as data indicating the operation rate of the airport parking lot 43 included in the operation rate data Du.

The fourth charge/discharge management system 34 is operated by the manager of the small facility or outdoor parking lot 44 as a consumer. The small facility or outdoor parking lot 44 is, for example, a parking lot of a convenience store or supermarket, or a coin parking lot.

The balancing market system 51 is operated by an operator of an electricity trading market, including a balancing market.

The aggregation support device 20 sells the adjustment power from each parking lot indicated by the adjustment power data Db to the supply and demand adjustment market by communicating with the supply and demand adjustment market system 51 for bidding into the adjustment power market. When the aggregation support device 20 receives a demand response command or an instruction for adjustment power from the supply and demand adjustment market system 51, it outputs the adjustment power data Db by transmitting the adjustment power data Db to each charge and discharge management system as an external system. For example, when the aggregation support device 20 receives a request for 1000 kWh, it allocates the adjustment power from the large facility parking lot 41, the employee parking lot 42, the airport parking lot 43, and the small facility or outdoor parking lot 44 in the form of 200 kWh, 200 kWh, 500 kWh, and 100 kWh, respectively. Each charge and discharge management system contributes the adjustment power from the corresponding parking lot to the supply and demand adjustment market according to the adjustment power data Db transmitted from the aggregation support device 20. The supply and demand adjustment market system 51 communicates with the aggregation support device 20 for settlement purposes, and pays incentives to each charge and discharge management system according to the adjustment capacity contributed by the corresponding parking lot.

Characteristics of parking lot charging include the occurrence of peaks due to simultaneous charging caused by a large number of connected vehicles, and the potential for adjustment capacity. According to this embodiment, it is possible to implement logic that calculates how much adjustment capacity can be provided while avoiding peaks, i.e., the adjustment capacity margin. Based on the margin information of each parking lot, a mechanism can be constructed in which the aggregation coordinator places a bid on the supply and demand adjustment market. The manager of each parking lot can receive an incentive for contributing adjustment capacity. At least a portion of the incentive may be returned to the user of each vehicle. The aggregation coordinator can ensure adjustment capacity using vehicles that can be charged and discharged.

The configuration of the aggregation support device 20 according to this embodiment will be described with reference to FIG. 2.

The aggregation support device 20 includes a control unit 21, a memory unit 22, and a communication unit 23.

The control unit 21 includes at least one processor, at least one programmable circuit, at least one dedicated circuit, or any combination thereof. The processor is a general-purpose processor such as a CPU or GPU, or a dedicated processor specialized for a specific process. "CPU" is an abbreviation for central processing unit. "GPU" is an abbreviation for graphics processing unit. The programmable circuit is, for example, an FPGA. "FPGA" is an abbreviation for field-programmable gate array. The dedicated circuit is, for example, an ASIC. "ASIC" is an abbreviation for application specific integrated circuit. The control unit 21 executes processes related to the operation of the aggregation support device 20 while controlling each part of the aggregation support device 20.

The storage unit 22 includes at least one semiconductor memory, at least one magnetic memory, at least one optical memory, or any combination thereof. The semiconductor memory is, for example, a RAM or a ROM. "RAM" is an abbreviation for random access memory. "ROM" is an abbreviation for read only memory. The RAM is, for example, an SRAM or a DRAM. "SRAM" is an abbreviation for static random access memory. "DRAM" is an abbreviation for dynamic random access memory. The ROM is, for example, an EEPROM. "EEPROM" is an abbreviation for electrically erasable programmable read only memory. The storage unit 22 functions, for example, as a main storage device, an auxiliary storage device, or a cache memory. The storage unit 22 stores data used in the operation of the aggregation support device 20 and data obtained by the operation of the aggregation support device 20.

The communication unit 23 includes at least one communication interface. The communication interface is, for example, a LAN interface. The communication unit 23 communicates with each charge/discharge management system and the supply and demand adjustment market system 51. The communication unit 23 receives data used in the operation of the aggregation support device 20, and transmits data obtained by the operation of the aggregation support device 20.

The functions of the aggregation support device 20 are realized by executing a program according to this embodiment on a processor serving as the control unit 21. That is, the functions of the aggregation support device 20 are realized by software. The program causes a computer to execute the operations of the aggregation support device 20, thereby causing the computer to function as the aggregation support device 20. That is, the computer functions as the aggregation support device 20 by executing the operations of the aggregation support device 20 in accordance with the program.

The program may be stored in a non-transitory computer-readable medium. Examples of the non-transitory computer-readable medium include flash memory, a magnetic recording device, an optical disk, a magneto-optical recording medium, or a ROM.

"ASP" is an abbreviation for application service provider. A program is information used for processing by a computer and includes those equivalent to a program. For example, data that is not a direct command to a computer but has properties that define computer processing falls under "those equivalent to a program."

Some or all of the functions of the aggregation support device 20 may be realized by a programmable circuit or a dedicated circuit as the control unit 21. In other words, some or all of the functions of the aggregation support device 20 may be realized by hardware.

The operation of the aggregation support device 20 according to this embodiment will be described with reference to FIG. 3. This operation corresponds to the aggregation support method according to this embodiment.

In step S1, the control unit 21 of the aggregation support device 20 acquires operation rate data Du indicating the utilization rate of the charging/discharging equipment in each parking lot as the operation rate of each parking lot for multiple parking lots in which charging/discharging equipment is installed to charge/discharge one or more vehicles parked in each parking lot. Specifically, the operation rate data Du is acquired by the following procedure.

Each charge/discharge management system transmits data indicating the usage status of the charge/discharge equipment in the corresponding parking lot to the aggregation support device 20. The control unit 21 of the aggregation support device 20 receives the transmitted data from each charge/discharge management system as an external system via the communication unit 23. Based on the received data, the control unit 21 calculates the actual usage rate of the charge/discharge equipment in each parking lot as the operation rate of each parking lot. The control unit 21 obtains the obtained calculation result as operation rate data Du.

Instead of calculating the actual utilization rate of the charging/discharging equipment in each parking lot as the operation rate of each parking lot, the utilization rate of the charging/discharging equipment in each parking lot may be predicted as the operation rate of each parking lot. In such a modified example, the control unit 21 of the aggregation support device 20 receives a type of data specified in advance for each type of parking lot from an external system via the communication unit 23. For example, for a parking lot of an entertainment facility or commercial facility in a city, such as a large facility parking lot 41, the control unit 21 receives people flow data D1 indicating the flow of people in the city from a mobile communication operator system as an external system. For the employee parking lot 42, the control unit 21 receives work schedule data D2 indicating the work schedule of employees from the second charging/discharging management system 32 as an external system. For the airport parking lot 43, the control unit 21 receives user data D3 indicating the number of airport users from the third charging/discharging management system 33 as an external system. Based on the received data, the control unit 21 predicts the utilization rate of the charging/discharging equipment in each parking lot as the operation rate of each parking lot. For example, the control unit 21 predicts a higher occupancy rate for the large facility parking lot 41 as the flow of people indicated by the people flow data D1 increases. The control unit 21 identifies the number of employees by referring to the work schedule indicated by the work schedule data D2, and predicts a higher occupancy rate for the employee parking lot 42 as the identified number of employees increases. The control unit 21 predicts a higher occupancy rate for the airport parking lot 43 as the number of users indicated by the user data D3 increases. The control unit 21 acquires the obtained prediction results as occupancy rate data Du.

In step S2, the control unit 21 of the aggregation support device 20 determines the adjustment power from each parking lot that is contributed by discharging one or more vehicles by the charging/discharging equipment in each parking lot, according to the occupancy rate of each parking lot indicated by the occupancy rate data Du acquired in step S1. For example, the control unit 21 increases the adjustment power from the large facility parking lot 41 as the occupancy rate of the large facility parking lot 41 indicated by the occupancy rate data Du is higher. The control unit 21 increases the adjustment power from the employee parking lot 42 as the occupancy rate of the employee parking lot 42 indicated by the occupancy rate data Du is higher. The control unit 21 increases the adjustment power from the airport parking lot 43 as the occupancy rate of the airport parking lot 43 indicated by the occupancy rate data Du is higher. The control unit 21 increases the adjustment power from the small facility or outdoor parking lot 44 as the occupancy rate of the small facility or outdoor parking lot 44 indicated by the occupancy rate data Du is higher.

The control unit 21 of the aggregation support device 20 may apply a weighting coefficient predefined for each type of parking lot to the adjustment power from each parking lot. In particular, when the utilization rate of the charging/discharging equipment in each parking lot is predicted as the occupancy rate of each parking lot, it is effective to apply a weighting coefficient according to the ease of prediction to the adjustment power from each parking lot.

As shown in FIG. 4, the occupancy rate of the large parking facility 41 is difficult to predict, and precise prediction is required for discharge utilization in the large parking facility 41. Therefore, when such precise prediction is difficult, the control unit 21 of the aggregation support device 20 may apply a weighting coefficient smaller than 1 to the adjustment power from the large parking facility 41. In other words, the control unit 21 may reduce the adjustment power from the large parking facility 41.

The occupancy rate of the employee parking lot 42 or the airport parking lot 43 is easy to predict, and it is easy to obtain a consolidated adjustment power by utilizing discharge in the employee parking lot 42 or the airport parking lot 43. Therefore, the control unit 21 of the aggregation support device 20 may apply a weighting coefficient greater than 1 to the adjustment power from the employee parking lot 42 or the airport parking lot 43. In other words, the control unit 21 may increase the adjustment power from the employee parking lot 42 or the airport parking lot 43. Since the occupancy rate of the airport parking lot 43 is easier to predict than that of the employee parking lot 42, the control unit 21 may apply a weighting coefficient greater than that of the employee parking lot 42 to the adjustment power from the airport parking lot 43. The accuracy of prediction of the occupancy rate of the airport parking lot 43 can also be improved by linking it with airline ticket data.

Because the time that a vehicle parked in a small facility or outdoor parking lot 44 stays in the parking lot is short, it is difficult to utilize discharge in the small facility or outdoor parking lot 44. Therefore, the control unit 21 of the aggregation support device 20 may apply a weighting coefficient smaller than 1 to the adjustment power from the small facility or outdoor parking lot 44. In other words, the control unit 21 may reduce the adjustment power from the small facility or outdoor parking lot 44. The control unit 21 may apply a weighting coefficient smaller than that of the large facility parking lot 41 to the adjustment power from the small facility or outdoor parking lot 44. The same applies to the highway service area or parking area as to the small facility or outdoor parking lot 44.

The control unit 21 of the aggregation support device 20 may apply a predefined weighting coefficient to the adjustment power from each parking lot for each purpose of the parked vehicle, such as an individual, a shared car, a rental car, or a delivery company or bus company.

In step S3, the control unit 21 of the aggregation support device 20 outputs adjustment capacity data Db indicating the adjustment capacity from each parking lot determined in step S2. Specifically, the control unit 21 outputs the adjustment capacity data Db by transmitting the adjustment capacity data Db to each charge/discharge management system as an external system via the communication unit 23. For example, the first charge/discharge management system 31 contributes the adjustment capacity from the large facility parking lot 41 indicated by the adjustment capacity data Db transmitted from the aggregation support device 20 to the supply and demand adjustment market. The second charge/discharge management system 32 contributes the adjustment capacity from the employee parking lot 42 indicated by the adjustment capacity data Db transmitted from the aggregation support device 20 to the supply and demand adjustment market. The third charge/discharge management system 33 contributes the adjustment capacity from the airport parking lot 43 indicated by the adjustment capacity data Db transmitted from the aggregation support device 20 to the supply and demand adjustment market. The fourth charge/discharge management system 34 contributes the adjustment capacity from the small facility or outdoor parking lot 44 indicated by the adjustment capacity data Db transmitted from the aggregation support device 20 to the supply and demand adjustment market.

According to this embodiment, chargeable and dischargeable vehicles parked in parking lots can be effectively used for resource aggregation. By increasing the proportion of adjustment power contributed by parking lots with easily predictable operating rates, such as airport parking lots 43, it becomes easier to secure adjustment power.

Instead of contributing adjustment power to the supply and demand balancing market, adjustment power may be contributed directly to a business operator such as a power transmission and distribution business operator or a retail electricity business operator. In such a modified example, as shown in FIG. 5, the resource aggregation system 10 communicates for bidding with the business operator system 52 instead of the supply and demand balancing market system 51, thereby selling adjustment power from each parking lot directly to a business operator such as a power transmission and distribution business operator or a retail electricity business operator.

The operator system 52 is operated by an operator such as an electricity transmission and distribution operator or a retail electricity operator.

The aggregation support device 20 can communicate with the business operator system 52 via a network. The aggregation support device 20 directly sells the adjustment capacity from each parking lot indicated by the adjustment capacity data Db to a business operator such as a power transmission and distribution business operator or a retail electricity business operator by communicating with the business operator system 52 for billing. When the aggregation support device 20 receives a demand response command or an instruction for adjustment capacity from the business operator system 52, it outputs the adjustment capacity data Db by transmitting the adjustment capacity data Db to each charge and discharge management system as an external system. Each charge and discharge management system directly contributes the adjustment capacity from the corresponding parking lot to a business operator such as a power transmission and distribution business operator or a retail electricity business operator according to the adjustment capacity data Db transmitted from the aggregation support device 20. The business operator system 52 pays an incentive according to the adjustment capacity contributed by the corresponding parking lot to each charge and discharge management system by communicating with the aggregation support device 20 for settlement.

The present disclosure is not limited to the above-described embodiments. For example, two or more blocks shown in the block diagram may be integrated, or one block may be divided. Two or more steps shown in the flowchart may be executed in parallel or in a different order, instead of being executed in chronological order as described, depending on the processing capabilities of the device executing each step, or as needed. Other modifications are possible without departing from the spirit of the present disclosure.
