Optimal planning of electric vehicle charging stations is an important research area in the study of flexible interaction between electric vehicle and smart grid.The calculation method of cost-benefit and life cycle cost of electric vehicle charging stations is analyzed in the operation period of electric vehicle charging stations,based on which,a method of calculating charging station capacity using the data from the traffic flow is proposed,and an optimal objective of the operator gaining best net present value is proposed.With the traffic flow,the power quality and economy of grid and charging demand of customer as constraints,the location and capacity of charging stations can be determined.In addition,the optimal planning model of charging stations considering life cycle cost theory is proposed,with the quantum genetic algorithm used to solve the model. The simulation of the example has confirmed that the optimal planning model and solving method are effective.
