In order to optimize the energy storage configuration of electric vehicle charging stations,reduce the load fluctuation,increase output power and reduce costs,this article put forward a method of energy storage configura-tion of electric vehicle charging stations under load fluctuation.Firstly,Copula function was used to analyze the corre-lation between electric vehicle charging load and photovoltaic output,and then a joint probability density graph be-tween the two was drawn.Meanwhile,a joint output probability density function was constructed to analyze the load fluctuation of electric vehicle charging station.Secondly,the minimum cost was taken as the objective.Thirdly,an en-ergy storage configuration objective function for electric vehicle charging station was established.Finally,the artificial bee colony algorithm was introduced to obtain the optimal solution for energy storage configuration of electric vehicle charging stations under constraint conditions.The experimental results show that after the proposed method is con-figured,the load of the charging station system is significantly reduced,and there is no failure load.The output power is improved,and the cost is reduced.This verifies that the proposed method has a good energy storage configuration effect.
