Research on operation optimization of grid-forming charging spot based on stochastic matching

In response to the operation problem of electric vehicle charging spots with grid forming capabilities within grid-connected micro-grids, this paper studies an optimization method for the operation of grid-forming charging spots based on stochastic scenario matching, which provides decision support for the optimization of bi-directional power allocation operation of grid-forming charging spots in grid-connected micro-grids. This paper first discusses the structure and operation mode of a micro-grid system with grid-forming charging spots. Then, a two-stage stochastic operation optimization model considering the randomness of distributed power sources, loads, and electric vehicles is constructed, and a scenario tree based random matching optimization method is proposed. Finally, the effectiveness of the proposed method is demonstrated through experiments. The results show that the proposed method can obtain a control strategy close to the actual system operation logic, providing effective support for the power allocation of grid-forming charging spots.
