Abstract :
The uncertainty of user charging behavior is analyzed base on a large number of the recorded field data on charging load of electric vehicles. Horary distribution model of charging load of electric vehicles is established based on the charging start time and duration which are considered as two key factors affecting the temporal uncertaint. According to the spatial distribution, the charging load area is divided. Combined with the uncertainty analysis of temporal and spatial distribution, a composite model of electric vehicle charging load is established. Through the analysis of the examples, the impact of charging load of electric vehicle on the power grid and the stable operation of local distribution network is researched. The results show that mixed construction of DC fast charging mode and AC slow charging mode will help alleviate the impact of Electric Vehicle Charging Load on local distribution network.
