At present, China has the world's largest number of electric vehicles, and the total amount of charging power from electric vehicles is growing rapidly. Due to the small scale and high dispersion of a single electric vehicle, however, it is difficult for electric vehicles to participate the electricity market directly and share the dividends of electricity reform in China. Reducing electricity prices through the participation of electricity market can effectively encourage consumers to choose and use electric vehicles. Based on the analysis of the current Chinese electricity market, this paper studies the way in which electric vehicles participate in the electricity market in China, and designs corresponding market participation mechanisms.

With the future large-scale access of renewable energy, the electric power system will accelerate the development in the direction of clean and low carbon, especially under a high proportion of renewable energy electric power system, the structure and layout of China’s electric power production has been deeply adjusted. Thus, the balance situation of the power quantity is more complex, the risk of failure chain reaction caused by the simple accident increases greatly. Moreover, with the increase demand for flexible resources in power system, the importance of thermal power plant as well as ancillary service market is highlighted. Considering the difference between provincial and inter-provincial market, an overall mechanism design of China ancillary service market is put forward
