Abstract: A large quantity of charge/discharge loads with spatio-temporal uncertainty increase based on the promotion of electric vehicles(EVs), which affects the safety and stability of power system. The accurate spatio-temporal distribution prediction of EV charge and discharge loads is the basis for load balancing and dispatching in power system. Therefore, the researches on the spatio-temporal distribution prediction of EV charging and discharging loads in recent years are reviewed. The mechanism of the key factors of EV charging and discharging loads distribution are analyzed firstly. Three aspects are considered, which are path factors, charging factors and other uncertainties. Besides, the factors’ difference of various types of EV is compared. Secondly, the previous methods with regard to modeling of spatiotemporal EV charging and discharging are classified and systematically summarized. Finally, the shortcomings of the existing researches are revealed, and research gaps are identified for further exploration.
