Abstract: In response to the increasing number of electric vehicles（EVs） and the rapid development of distributed generation in recent years, which has caused a significant impact on the power grid, this paper proposes an optimal scheduling scheme that comprehensively considers controllable resources such as electric vehicles and flexible loads, reducing the operating costs of micro power grids and reducing the impact on the power grid. First, a typical "source-grid-load-storage" microgrid topology considering electric vehicles and various flexible loads is established. Then, it models the adjustable resources in the microgrid, considers the redistribution of peak and valley periods under different permeabilities and different numbers of electric vehicles, calculates the minimum operating cost of the microgrid under different permeabilities, energy storage capacities, and numbers of electric vehicles, and determines the optimal microgrid configuration scheme. Finally, simulation results show that the proposed optimization scheme can reduce the operating cost of the microgrid by 8.1%, while maintaining contact line power fluctuations to 50 kW or less and maintaining high user satisfaction with flexible loads.
