By operating the power trading system described above, it is possible to provide a power trading service to which the power trading matching method of the present invention is applied. FIG. 7 is a flow diagram showing the operation of the power trading system. Note that the processing procedure described below is only an example, and each process may be changed as much as possible. Further, regarding the processing procedure described below, steps can be omitted, replaced, or added as appropriate depending on the embodiment.

As shown in FIG. 7, first, buying and selling reason information, which describes the reason and purpose of electricity trading in advance, is transmitted from each power plant, consumer (including prosumer), and PPS to the intermediary server 20 (S101, S301), the transmitted buying and selling reason information is collected and accumulated by the buying and selling reason collecting unit 24c on the intermediary server 20 side (S201).

Then, each power plant or consumer uses the equipment of the user system 4 to generate power, and the surplus power is transmitted to the power grid or the PPS 5. At this time, power generation data and power consumption data are generated, and these data are aggregated as performance data by the smart meter 41 and input to the performance data management section 72. The analysis results of the performance data management unit 72 are accumulated in the database, and power transmission information is generated based on the analysis results and transmitted to the intermediary server 20 and PPS 5 together with the performance data (S202).

In this step S202, when power reception from the consumer starts, power reception time information is recorded. This power reception information is stored in the storage as procured power information. In addition, market information is collected at the start of power reception, and the correlation between power supply and demand and external information is analyzed to predict future power supply and demand. The marginal profit is calculated by adding a predetermined profit. Specifically, we take into consideration the market electricity price at the time of power reception, the cost required to procure power from consumers, the cost of lost power lost during storage, and the remaining capacity during storage. The marginal profit is calculated by adding the minimum necessary fee obtained by PPS5 etc.

The demand forecast here analyzes external information such as market information and past changes in electricity demand as big data, and uses machine learning functions of AI (artificial intelligence) such as deep learning to By accumulating feature points and extracting correlations (trends) between each piece of information based on the commonality of the feature points, future electricity demand can be predicted based on the commonality of the feature points that match current market information. It's okay.

In addition, in a PPS that has an electricity storage function, the marginal profit calculated based on the presence or absence of profit is compared with the predicted market price, and if the expected market price at the time of receiving electricity exceeds the marginal profit, it is sold as is. The timing of the buying and selling transaction may be adjusted, such as waiting for another electricity sale timing, storing the electricity on that day, carrying it over to the next day, and executing the electricity sale.

Next, based on the collected buying and selling reason information, a process of categorizing the user system on the power selling side and the user system on the power buying side is executed (S203), and a plurality of balancing of the user system groups is performed according to the generated categorization. A balancing group composition step of dividing into groups is executed (S204).

After that, sale data and purchase data are transmitted from the electricity selling side consumer and the electricity selling side consumer (S104 and S304), and matching processing is executed (S205). Then, the intermediary server 20 performs matching according to the balancing group formed in step S204, and establishes an electricity transaction based on the matched selling data and purchasing data to generate contract data (S205). .

In response to this contract, based on the contract data and actual data, final data including the final value of the amount of electricity generated or used by each user during each electricity usage period and the amount of consideration related to the amount of electricity is generated. , based on the confirmed data, a payment process is executed to settle the consideration paid or received by each user (S105, S206, and S3305).
