The invention discloses a multi-microgrid system optimization scheduling method considering EV coordinated charging and demand response. The method comprises the following steps: constructing an electric vehicle load access and departure microgrid time model and a time slot division model; a dynamic urgency index is introduced on the basis of the established electric vehicle load access and departure microgrid time model and the time slot division model, and an electric vehicle coordinated charging model with the minimum load peak-valley difference as the target is established; establishing a cold load model and a heat load model; on the basis of the established cold and heat load models, considering cold and heat load demand response, and establishing a master-slave game model with the multi-microgrid benefit maximization as the target by adopting the electric load obtained by the electric vehicle coordinated charging model; in a multi-microgrid integrated energy system containing electric energy interaction and cooling and heating load demand response, electric vehicle coordinated charging is considered, and optimization solution is carried out based on the established master-slave game model. According to the invention, the peak-valley difference of the load is greatly reduced, the power utilization pressure at the peak of the micro-grid is effectively reduced, and the EV can be better accessed to the micro-grid.
