With the development of technologies of large capacity batteries and electric vehicles, the number of electric-car will increase dramatically. As a result, disorderly charging will cause a significant impact on the safe and economic operation of power system. Charging load has its adjustability on dual scale of time and space. With this feature, load dispatch in both time and space for dual scale is possible which has a positive effect on the operation of power grid. This paper introduces some recent research achievements on orderly charge control, including electric vehicle charging demand characteristics and load model. Explores the orderly charging, especially the control effectiveness of V2G mode on cases of peak-shift, coordinated operation of new energy, frequency regulation and other aspects. Orderly control strategy for electric vehicles is also put forward. Finally, points out the deficiencies of current research and prospects for future.
