A survey of influence of electrics vehicle charging on power grid
Electric vehicle (EV) industry gets into fast growth period in China, so that charging of large scale of EV will pose inevitable impacts on power grid in the future. In this article, the main factors and modeling methods of EV charging load are analyzed; The literature reviews are carried out on EV integration and impacts on power grids, including grid access capability, power quality, power economy and environment; Additionally, the benefits and realization methods of smart charging strategy are discussed. The current research on V2G (vehicle to grid) operation are summarized as well. Finally, the unresolved problems and possible future research areas are presented.
