Optimal Location of Fast Charging Station on Residential Distribution Grid

Abstract—The population of the Electric vehicle (EV) has been increasing rapidly worldwide due to its environmental friendly. However, there is a need to prepare effective electric charging station infrastructures to fill up battery for future day-to-day energy consumption. Then the electric charging station must be extensively installed to sufficiently serve a number of EVs, especially in metropolitan areas. Since electric charging station will be used simultaneously by many EVs and may lead to the unreliability of the distribution system. This paper therefore proposes an optimal location of fast charging station (FCS) on residential distribution grid aiming to minimize annual cost of power line loss, travelling cost of EVs in recharging, investment cost and variable cost of operation of FCS while maintaining system security. Ant colony optimization (ACO) is employed to minimize total cost by searching best location of FCS in a traffic area. A modified IEEE 69-bus system is used to verify the proposed technique. The results show that the proposed method found the optimal location of FCS on residential power distribution system with minimum cost while satisfying security constraints.

Index Terms—Distribution system, electric vehicle, ant colony optimization and fast charging station.
