Optimization of Operation Strategy of Electric Vehicle Charging Station in Multi-station Fusion Scene

In order to create a new model of energy sharing and economic reciprocity, the State Grid Company began to promote the "multi-station integration" business rapidly in 2020. The purpose is to make full use of substation resources, give full play to the value of multi-station fusion, improve the economy of multi-station fusion, and ensure the economic operation of electric vehicle charging station. In this paper, through the construction of electric vehicle charging station load model and energy storage system model, the annual comprehensive total cost of charging station is taken as the objective function and the optimal operation strategy of charging station under the background of multi-station fusion is established and verified by example analysis.
