Review on Studies of V2G Problem in Electric Vehicles

As mobile energy storage units,electric vehicles play a flexible and support role in the safe operation of pow. er grid. In this paper,the status quo of vehicle-to-grid(V2G)technology was analyzed in consideration of its effect on power grid,users,energy storage,environment,etc. From the aspects of grid-side and user-side,the related studies concerning the effect of V2G on power grid scheduling,power quality,load balance,economic efficiency of distribu. tion network,grid frequency modulation,and demand response and revenue of users were summarized. Moreover,the studies on the effect of V2G technology on the hierarchical energy storage utilization of power battery and environment were also surveyed. Finally,the potential research directions of V2G in the future were discussed.
