Abstract:Load-based virtual power plants (LB-VPP) provide flexible response and regulation services by aggregating users with load regulation capabilities to participate in electricity market trading. Up to now, research on virtual power plants has mostly focused on their marketization mechanism and scheduling strategy, and there is no unified method for the settlement mechanism of virtual power plants enter the market. This paper uses gateway data as the basis data for settlement, divides the wholesale market electricity transaction charge of LB-VPP into three parts: electricity quantity charge, market operation charge, dividends and transmission charge respectively. Based on the transaction declaration constraints, curve deviation constraints, and adjustment capacity constraints of LB-VPP, the assessment and recovery mechanism for deviation electricity quantity and the allocation and refund mechanism for electricity transaction charge is established, and a practical and feasible wholesale side settlement method is provided for LB-VPP to participate in the electricity market. Based on the operation situation of the Shanxi Province electricity market and the pilot settlement results, the method proposed in this paper can effectively solve the settlement difficulties faced by LB-VPP enter the market.
