Abstract
This article studies the charging characteristics of different kinds of electric vehicles and, in particular, improves the sampling method of initial state-of-charge for hybrid electric vehicles. With consideration of the influences that the charging time may exert on a customer choice of charging start time, and introducing the quantity of simultaneously charging electric vehicles, a probability model of a hybrid electric vehicle charging load is built. Then an improved probability simulation method of charging demand is proposed for multiple kinds of electric vehicles connected with a distribution grid. Finally, the impact of charging electric vehicles is analyzed based on an IEEE 34-node test feeder.
