Planning Method for Charging Station Based on the Hybrid Optimisation Algorithm

In light of the uneven development of charging infrastructure caused by the growing quantity of electric vehicles, a charging station planning method is proposed to comprehensively consider the interests of charging stations, electric vehicle subscribers, and distribution networks. Firstly, the charging station planning model is constructed, and the objective function is constructed with the target of minimising the charging station construction cost, user loss cost, and distribution network loss cost. Secondly, to solve the issues with the current algorithms' low efficiency and insufficient global optimisation capabilities, a hybrid optimisation algorithm based on the Differential Evolutionary (DE) and the Improved Particle Swarm Optimization (IPSO) is adopted to resolve the proposed planning model, and to identify the service scope, optimum number and location of charging stations. Finally, by using part of an urban region in a city in northern China as a case for planning purposes, the proposed algorithm and model are validated to be effective and feasible.
