This paper investigates a collective control problem for a parking-based large-scaled EVs. A parking under electric energy management by a virtual power plant is targeted under assumption of decentralized charging/discharging rate control of the individual EVs. A decentralized charging control strategy is proposed by solving a mean-field game problem with the cost function that balancing between the collective charging behavior and the charging level of each EV. Simulation results is finally demonstrated to validate the proposed control strategy.
