Study on Charging Load Model and Quantification Method of Adjustable Potential of Electric Vehicle Cluster in Old Residential Area
In recent years,with the gradual increase in the number of electric vehicles in old residential areas,a large number of electric vehicles are integrated into the power grid,charging load disorderly access,pile utilization rate surge,charging load superimposed power load,resulting in increased load fluctuation of the distribution network in old residential areas,further widening of load peaking and valley difference,short-ened distribution life,poor experience of owners,and high cost of distribution facility transformation.The old community with insufficient reservation for the installation of charging facilities has gradually evolved into a real risk for users.Therefore,this paper proposes an electric vehicle cluster charging load model and ad-justable potential quantification method in old residential areas with the overall goal of improving the stable,economic and intelligent operation level of distribution network under the background of large-scale electric vehicle access,and solves the long-term decentralized management and independent operation of charging fa-cilities in residential areas.
