Coordination Dispatch of Electric Vehicles Charging/Discharging and Renewable Energy Resources Power in Microgrid

high penetration level of EVs could bring about a large impact on microgrid. Therefore, considering the coordination between
renewable energy sources and EVs, a optimization model is proposed in this paper. In the optimization model, the minimum
variance of equivalent load as the objective function, considering the electric vehicle driving behavior and electric vehicle
capacity constraints, EVs charging/discharging power in each scheduling period is obtained. Simulation result shows the
effectiveness of the model. The results show that charging/discharging of EVs can be dispatched to reduce the equivalent load
and increase absorptive capacity of renewable energy.
