Research on Multi-Vehicle Power Distribution Method in Charging and Discharging Station Discharge Mode

With the popularization of electric vehicles and the vigorous development of V2G technology, the charging and discharging strategies of the current electric vehicle charging and discharging system for different charging and discharging requirements cannot meet the needs of both users and the power grid. Aiming at the discharge problem of electric vehicle charging and discharging station with bidirectional charging and discharging capability, a power allocation strategy is proposed. First, the user side is modeled in the electric vehicle discharge mode to determine the conditions under which participation in the discharge can be enabled. Secondly, combined with the constraints of the user side and the internal conditions of the charging and discharging station, the V2G capacity of the electric vehicle is predicted, and the discharge power allocation strategy of the charging and discharging station is formulated. Finally, according to the actual electric vehicle data simulation, the feasibility of the discharge power allocation strategy is verified, which provides a feasible reference for the management method of charging and discharging stations in the future.
