Electrified transportation is an important scenario for the coupling of transportation and electricity,and the large-scale access of electric vehicles has a significant impact on the active/reactive power scheduling of the power system.A distribution network active/reactive power optimization method considering the orderly charging and reactive power support of electric vehicles was proposed.Firstly,based on the charging characteristics of electric vehicles,a power control model for orderly charging of electric vehicles was established to achieve orderly charging control for grid connection of electric vehicles;secondly,a two-layer optimization model was constructed for orderly charging and reactive power support of electric vehicles that combines factors of user side and grid side,to achieve active/reactive power interaction between electric vehicles and the grid;finally,the rationality and reliability of the proposed method were verified through simulation.By controlling the power factor of orderly charging of electric vehicles,it can significantly reduce charging expenses at user side,while also effectively improving grid load fluctuations and reducing network losses,providing new ideas for solving the problem of large-scale connection of electric vehicles to the grid.
