Abstract： In order to solve the problem of fluctuation of wind-power output and disordered charging of electric vehicles connected to the power grid, a two-stage optimal dispatching model of electric vehicles connected to the micro grid by classification was established according to the sensitivity of electric vehicle users to the incentive factors, and a case study was carried out. The research results show that compared with disordered charging, the two-stage dispatching micro grid of electric vehicles significantly reduces the value in load peak and valley periods, the energy storage unit can basically meet the operation demand of the micro grid, the wind-energy utilization rate is up to 95.43%, and the connection line exchange power is only 24.2 kW, which significantly reduces the impact of wind-energy fluctuations of the micro grid on the large power grid. With the increase of the proportion of class III electric vehicles, the utilization rate of wind-power increased obviously. An example shows that the proposed two-stage optimal dispatching model can effectively reduce the power purchased from the micro grid, which improves the utilization rate of wind and wind, and improves the influence of micro grid power fluctuations on the large power grid.
