Abstract: In order to give full play to the scheduling potential of electric vehicles and improve the competitiveness of electricity retailers in participating in the electricity market, a day-ahead-intraday optimal scheduling model for electricity retailers considering electric vehicles is proposed. In the day-ahead stage, considering the price-based demand response method, electricity retailers promote the orderly charging and discharging of electric vehicles through electricity purchase and sale prices. There is a Stackelberg game relationship between electricity retailers and electric vehicles. In the intraday stage,the electricity retailers adopt an intraday rolling optimization approach to revise the day-ahead plan, and consider incentive-based demand response methods to mobilize the flexibility of electric vehicles.Meanwhile, the model adopts a multi scenario analysis method to consider the uncertainty of wind power and load forecasting. The analysis results of the example show that adopting the proposed method can effectively reduce the electricity purchase cost of electricity retailers and the electricity consumption cost of electric vehicles, give full play to the scheduling potential of electric vehicles, reduce unbalanced costs,wind curtailment rates and interruptible load calls, and realize the “win-win” of electricity retailers and electric vehicle users.
