BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 It is a flow chart of the regional balancing market pricing method according to the first embodiment of the present invention. DETAILED DESCRIPTION

[0038] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0039] The regional balancing market is operated by a third-party virtual power plant organization that is independent of the power grid company. The methods by which virtual power plants promote regional balance include: purchasing electricity from power generation resources, and providing electricity price subsidies to power consumption resources to guide increased electricity consumption. Under the condition that the regional balancing market does not affect the original operation plan of the resources, the virtual power plant guides the internal resources of the region to participate in the regional balancing market. The market players in the regional balancing market include distributed power sources, controllable loads and energy storage within the region. Market players can apply to have the remaining capacity or units participate in the regional balancing market on the premise of meeting the original operation plan. When participating in the regional balancing market, each market player provides the virtual power plant with a quotation and a quotation curve, and then the virtual power plant calculates the unified electricity price of the regional balancing market based on the quotation and quotation information.

[0040] The first embodiment of the present invention relates to a regional balancing market pricing method, such as Figure 1 As shown, the following steps are included:

In this step, economic weights and comfort weights that match the types of different market entities are set to provide a basis for calculating a unified regional balancing service price.

[0043] Step 3, set the user willingness weight, and adjust the user willingness weight according to the quotation and quotation information. In this step, first set an initial user willingness weight, then integrate all the quotation and quotation information obtained, and evaluate whether the participation of market players in the regional balancing market meets expectations based on the integration results; if the participation of market players in the regional balancing market meets expectations, reduce the initial user willingness weight; if the participation of market players in the regional balancing market does not meet expectations, increase the initial user willingness weight. In this embodiment, if the total quotation information of market players participating in the regional balancing market accounts for 70% of the forecast, it means that the participation meets expectations, otherwise it means that the participation does not meet expectations.

[0044] Step 4: Based on the economic weight, comfort weight and adjusted user willingness weight, a regional balancing service pricing optimization model is constructed with the goal of minimizing the regional balancing service cost and maximizing the user willingness.
