Urban Electric Vehicle Charging Station Configuration in Consideration of the Characteristics of Urban Power Grid

Electric vehicles have multiple action in energy conservation, load shifting, etc. Proper charging facilities planning methods and models can guide construction, and promote the development of electric vehicles. Based on the regional characteristics of urban road network, this paper proposes a multi-objective programming model to configure electric vehicle charging station for urban road network. In this model, our objective is to maximize the total captured traffic, and to minimize the distribution network loss and voltage offset. Our model takes into account not only the convenience of the users, but also the impact on power quality and system operation and economy after charging stations are accessed to distribution systems. Using super-efficiency DEA model, we determine the objective function weights. And thus, the multi-objective programming is converted to a single-objective programming problems. And then improve BPSO algorithm is used to solve this single-objective optimization problem after conversion.
