An overview on V2G strategies to impacts from EV integration into power system

In recent years, due to the widespread use of EV, Vehicle to grid (V2G) has received wide attention. This paper considers power systems and provides an overview of some V2G issues. Two technical issues are detailed: bi-directional charger and charging/discharging strategy. Those two technical issues stems from two great problems of the electric vehicle (EV) integration into the power system: harmonics pollution and load fluctuation. Research trends of such topics are declared at last.
