JP-2026076319-A - Electricity trading system and electricity trading method
Abstract
[Problem] To provide a power trading system and power trading method that enable the revitalization of power trading in the collaboration between EVs and smart grids. [Solution] When the electricity demand situation meets predetermined conditions, the management device 1 transmits first information indicating the electricity purchase price to each of the multiple electricity trading devices. When an electricity trading device receives the first information, it determines whether or not to supply the available electricity to the electricity recipient based on the available electricity and the purchase price indicated by the first information. If it determines to supply the available electricity, it transmits second information indicating the available electricity to the management device. The management device identifies specific electricity trading devices from the multiple electricity trading devices in order of the amount of available electricity indicated by the second information, until the total amount of available electricity indicated by the second information received from the electricity trading devices reaches the amount of electricity requested. The management device then transmits third information to the identified electricity trading devices indicating that it is requesting the supply of available electricity. [Selection Diagram] Figure 2

Description
This invention relates to a power trading system and a power trading method. In recent years, it has been proposed that linking electric vehicles (EVs) with smart grids can be used to improve power management, such as adjusting the balance of renewable energy supply. Specifically, in this case, EVs can mitigate peak power demand by, for example, becoming suppliers of electricity during peak hours (see Patent Documents 1 and 2).

Embodiments of the present invention will be described below with reference to the drawings. However, these embodiments do not limit the technical scope of the present invention. [Example of a conventional power trading system 10 configuration] First, we will explain a specific example of a conventional electricity trading system 100. Figure 1 is a diagram illustrating a specific example of a conventional electricity trading system 100. The electricity trading system 100 shown in Figure 1 includes, for example, an electricity supplier 101 that converts non-renewable or renewable resources into electricity and supplies it, a power grid 102 that transmits electricity, electricity traders 103 such as power companies, electricity markets, and electricity exchange organizations that trade electricity, and electricity consumers 104 that consume electricity.Hereafter, the electricity supplier 101 will be described as including, for example, various equipment for supplying electricity from non-renewable or renewable resources, and control devices such as computers that control the supply of electricity.The power grid 102 will be described as including, for example, control devices such as computers that control the transmission of electricity.The electricity traders 103 will be described as including, for example, control devices such as computers that control the trading of electricity.Furthermore, the electricity consumers 104 will be described as including, for example, various equipment necessary to receive the supply of electricity, and control devices such as computers that control the supply of electricity. In the example shown in Figure 1, region R1 represents a configuration for power trading. Also, region R Figure 2 shows a configuration for supplying electricity. Specifically, in region R1, electricity consumers 10 4, for example, enters into a contract with the power trader 103 regarding power transactions and transmits a power supply request to the power supplier 101 via the power trader 103. Subsequently, in area R2, the power grid 102 communicates to the power consumer 104, for example, the power trader 103 and the power consumer 10 Power transmission will be carried out in accordance with the contract with party 4. For example, if the amount of electricity supplied by the power supplier 101 to the electricity consumer 104 exceeds the amount of electricity that the power supplier 101 can supply, a power outage may occur in homes, factories, etc. In such a case, the power supplier 101 needs to restore power as quickly as possible. However, conventional power trading systems 100, as shown in Figure 1, may lack flexibility in responding to emergency measures such as power outages, and restoration may take a long time. [Example configuration of the electricity trading system 10 implemented in this project] Next, a specific example of the power trading system 10 in this embodiment will be described. Figure 2 Figure 12 illustrates a specific example of the power trading system 10 in this embodiment. The power trading system 10 shown in Figure 2 includes, in addition to the components included in the power trading system 100 described in Figure 1, a management device 1, an EV2 (hereinafter also referred to as power trading device 2), and a solar panel 3. Hereinafter, multiple EV2s will be collectively referred to as an EV fleet. Furthermore, the following description will assume that the management device 1, EV2
