Research on Discharging Price of Electric Vehicle Participating in Power Grid Dispatching Considering Reverse Cost

As a controllable load and distributed energy storage unit, electric vehicle (EV) can use electric vehicle with vehicle-to-grid (V2G) technology to realize peak load shifting. In order to study the maximum bearing price of the grid in the discharge behaviour of electric vehicles, the paper takes the lowest operating cost of the grid as the objective function, establishes the optimal unit combination model of the standby unit during the peak load. The maximum bearing price of the gird is applied to the maximum cost of scheduling electric vehicle. Then the relationship between the maximum acceptable price and the power of the electric vehicle can be obtained. With the day-ahead load forecast, the upper limit of the electric vehicle acceptable discharge price is obtained. Finally, the simulation and analysis of the proposed method are carried out by numerical examples, and the feasibility and effectiveness of the proposed method are verified.
