Coordination Dispatch of Electric Vehicles Charging/Discharging and Renewable Energy Resources Power in Microgrid
Pages 157 - 163
Abstract
A large number of distributed powers access to the distribution network have a multifaceted impact on the power grid, while microgrid is an effective way to solve the impact of distributed generation on the power grid. In microgrid, the proportion of renewable energy is large, while it's output is random. Besides, electric vehicles(EVs) play an important role in microgrid and a 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.
