Research on Virtual Power Plant Resource Aggregation Considering Fast and Slow Charging of Electric Vehicles

With the increasing popularity of electric vehicles (EV s)., effectively integrating resources in virtual power plants (VPPs) under different charging modes to enhance grid stability and economic benefits has become a research focus. Considering the distribution characteristics., operational attributes., and adjustable features of EV s under fast-charging and slow-charging modes., the overall daily load curve of EV s can be derived for various charging scenarios. By determining the controllable capacity of EV s and the corresponding V2G (Vehicle-to-Grid) and G2V (Grid-to-Vehicle) power., and verifying the tracking performance of EV s to grid load signals through capacity regulation evaluation (CRE) coefficients., it becomes possible to design optimized charging and discharging scheduling strategies. This approach improves the efficiency and economic performance of coordinated EV and grid operation.
