Study on Optimal Scale and Layout of Electric Vehicle Charging Stations Based on Chaotic PSO Algorithm

Abstract

The index of investment cycle cost (ICC) and users convenience of electric vehicles are presented. Based on the aim to minimizing investing unit and user fees, fix a charging station model in scales and layouts. ICC consist initial investments, cost of network losses and investments for new transmission lines. Convenience is measured by electrical power consumption expense from users to the charging station. Adding constraint of grid security and economical efficiency, the optimization aim function was set which comprehensively considers investors and users cost and operation of power grid. Chaos Particle Swarm Optimization Algorithm (CPSO) was used to settle it. By empirical study of certain planning area, the proposed model and algorithm are proved to be scientific and effective.
