Abstract

The cluster effect of charging load characteristics of the large-number of EVs will put forward a new requirement on the power supply of distribution system. Based on the power load model of single EV charger in consideration of batteries SOC, the normal distribution of initial SOC and Poisson distribution of the time vehicles arrived, a charging station model for the cluster effect of EVs is presented to analyze the load demand in a parking lot in a day. Then an optimization strategy of vehicles charged orderly is proposed. By Monte Carlo simulation, it is verified that the proposed strategy could help on reducing peak and filling valley while meeting EVs users´ charging demand.
