The Impact of Charging Plug-In Electric Vehicles on Distribution System Considering Spatial and Temporal Distribution

Abstract:

The plug-in electric vehicles (PEVs) would exert inevitable impact on distribution system operation due to the spatial and temporal stochastic nature of the charging load. Based on the probability distributions of battery charging start time and the initial state-of-charge (SOC), the spatial and temporal charging loads of PEVs are analyzed on load nature and charging behaviors among different functional distribution areas. Taking IEEE 33-bus distribution system as an example, the Monte Carlo method is adopted to simulate charging load under different charging strategies and charging places for assess the impact on network loss and nodal voltage using standard load flow calculations. The results show that the choice of control strategies can improve the impacts of PEVs charging on distribution grid; a well-developed public charging infrastructure could reduce the stress on the residential distribution systems; optimal assignment of PEVs charging in residential area and industrial or commercial areas would provide a reference for charging infrastructure construction.
