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.
