Control Method of Command Deviation Considering Electric Vehicles Participating in Power Grid Dispatching

Under the background of “double carbon”, a large number of electric vehicles(EVs) provide flexible and adjustable resources for the grid. However, due to the randomness of the trips, the actual power response of each cluster of EVs can not fully follow the guidance power command issued by the power grid. This condition produces a deviation value. In order to reduce the deviation value, this paper takes the economic optimization of power grid as the objective function, and proposes a command execution deviation control method considering the participation of EVs in demand response. The power grid is divided into residential area, office area and commercial area. When the EVs dispatching has deviation, the deviation control in the region is adopted, and if the deviation still exists after the deviation control in the region, the cross-regional deviation control is carried out. Finally, the feasibility of the method is verified by an example.
