The promotion of NEVs is of great significance to the reduction of greenhouse gas emissions，prevention and control of air pollutants in China’s transportation industry. However，electricity consumption and electrical load increase brought by the large-scale promotion of NEVs shall deeply impact on the power generation side，transmission side，distribution side and supply side. Different from other power loads，the NEV load is highly flexible and dispatchable. It can serve as an energy storage facility to “discharge”，both reducing the impact of NEV charging on power grid and providing new scheduling resource for the power system regulation，so as to avoid investment wastes related to power grids and power supplies. Compared with the international situation，China’s vehicle network collaborative pilot projects are few in quantity and relatively simple in the application scenario. Conclusions are made from the analysis on the economic feasibility and technical feasibility of power grid coordination：in the near future，high economical realization of peak shaving and alleviation of network distribution and capacity expansion can be completed through the peak-valley electricity price difference and orderly charging；since 2030，frequency modulation auxiliary service through two-way charging and discharging will have higher market value. In addition，the cooperation among vehicles，power batteries，charging poles，and distribution network companies as well as the comprehensive upgrade and coordination of software platforms，hardware devices and communication protocols are required to realize the vehicle-grid collaboration.
