Abstract With the advancement of the carbon neutrality goal, the renewable energy consumption situation in China will become more severe. There is an urgent need to tap more power system flexibility resources. As a new type of variable load, electric vehicles can enhance the flexibility of the power system through interaction with the grid, and ensure the economic and safe operation of the system. In view of the current lack of research on the charging and discharging control of electric vehicle oriented to power system flexibility, this paper studies the control strategy of electric vehicles oriented to power system flexibility. Given the definition of the flexibility of the power system and electric vehicles, a flexibility dispatch scheme of "calculation of the maximum available flexibility-calculation of power system flexibility demand- flexible control of electric vehicle" is designed to fully tap the flexibility adjustment potentials of electric vehicles to promote the consumption of renewable energy. The analysis of case study demonstrates that the flexible control strategy of electric vehicles proposed in this paper can greatly improve the flexibility of the power system. At the same time, the solution time of the model in this paper is in the order of seconds, which can fully meet the real-time flexibility dispatch requirements of the power system.
