The configuration of energy storage capacity in electric vehicle charging stations is constrained by multiple conditions,resulting in suboptimal configuration results.Therefore,an automatic configuration method for energy storage capacity in electric vehi-cle charging stations based on an improved invasive weed algorithm is studied.Calculate the photovoltaic output of the electric vehicle charging station and estimate the load of the electric vehicle charging station based on the calculation results.According to the result of load estimation,multiple constraints such as economic cost,cycle efficiency of energy storage battery,transformer capacity,power level and number of Charging station are determined,and the objective function of automatic configuration of energy storage capacity of electric vehicle charging station is established.The objective function is automatically solved by using the improved invasive weed algorithm to obtain the global optimal solution,so as to realize the automatic configuration of energy storage capacity of electric vehicle charging station.The experimental results show that the proposed method has higher accuracy in load estimation of electric vehicle charging stations,better allocation of energy storage capacity,higher operational efficiency,and reliable configuration results.
