Research on the influence of electric vehicle charging on residential distribution network in southern China

The increased focus on environmental protection and the problem of lack of fossil energy around the world has prompted the rapid development of electric vehicles (EVs). With the popularity of private EVs, the original load characteristics of power system would be changed by EV charging behavior. And this would have impacts on the safety and economy of distribution network operation. In this paper, the Monte Carlo model is applied to simulate EV charging power of the urban residential district, according to the charging behavior of users in different scenarios. And the influence of EVs charging on residential distribution network was also analyzed. The demand side management (DSM) strategy was put forward to guide the charging behavior of the EV users to improve the safe and stable operation of power grid.
