Abstract: In order to give full play to the flexible and adjustable performance of electric heating load, this paper aggregates the electric heating load into a virtual power plant, and proposes an economic optimal scheduling method for peak regulation of electric heating aggregated virtual power plant, so as to provide a realistic solution for electric heating to actively participate in grid peak regulation.Firstly, the interactive mechanism and management structure of electric heating aggregation virtual power plant are analyzed and established; Then, the electric heating load demand response model considering differentiated demand is established; In order to maximize the expected economic benefits of virtual power plant, an economic optimal scheduling model of virtual power plant is established.The results show that the proposed method can realize the active participation of electric heating load in power grid operation and regulation economically and reasonably according to the differentiated needs of different users, and provide a practical solution for large-scale electric heating load to participate in power grid peak shaving.
