Abstract: Aiming at the load pressure caused by large-scale electric vehicle access to microgrid and the strong uncertainty of users’ electric vehicle charging, models of disordered charging and ordered charging/discharging of electric vehicles are established. At the same time, considering the uncertainty of new energy generation and load demand in the microgrid, a robust optimal dispatch method based on electric vehicles entering the grid is designed in the planning stage. Taking the minimum operating cost as the goal, the model finds the worst scenarios in the uncertain scenes and the operating cost in the two modes of disordered charging and orderly charging/discharging of electric vehicles. In the intraday dispatch stage, the real-time data of renewable energy generation and load demand are used to compensate and fine-tune the day-ahead planning scheme and operating cost under different conservative levels of the microgrid system for forecast errors. Finally, the validity and rationality of the proposed method are verified by simulation examples.
