An Energy Storage Capacity Planning Method of Charging Station Based on Load Data Clustering

Aiming at the issue of energy storage demand of existing charging stations,and taking the conversion of energy storage capacity of charging stations to the maximum daily net income as the objective function,the optimal allocation model of energy storage capacity of charging stations is constructed in this paper. Based on the annual actual operation data of charging stations, the k-means clustering method is applied for classification,and the particle swarm optimization algorithm is used to solve the optimization model of energy storage capacity.Finally,a typical example is given to verify the model and method. The results show that the model and method proposed in this paper can comprehensively consider the actual operation characteristics of the charging station throughout the year,reflect the annual income of energy storage more accurately and comprehensively,and can effectively guide the energy storage capacity configuration and planning and construction of existing charging stations.
