The technical，economic，environmental and policy background associated with the fast development of electric vehicles（EVs）are first clarified，followed by a review of the impacts of the extensive integration of numerous EVs on the power system concerned.The available dispatching and control methods relevant with EVs are next clarified.Then，suggestions are made about research work in the evaluation of the economic impacts of EVs on the power system，the dispatching problem and the optimization algorithm associated，as well as the charging and discharging control problem.
