Optimal Regulation Strategy for Electric Vehicle Load Clusters based on Demand Response

Abstract

With the rapid increase of electric vehicle ownership, the disorderly grid-connected charging of electric vehicles will bring great uncertainty to the smooth load of the distribution network, so it is important to optimize the regulation of electric vehicle clusters. To this end, an optimal regulation strategy for electric vehicle load clusters based on Demand Response is proposed. Through the analysis of the source load characteristics of electric vehicles, the elastic service rate and electricity incentive are innovatively proposed. Finally, the data of electric vehicles in the northern Hebei region is used for example simulation. The results show that the demand response-based EV cluster optimization and regulation strategy can reduce the charging cost of users and get a better dispatching effect while reducing the system load fluctuation.
