Optimal allocation of EV charging station in Distribution Network

Electric vehicles (EVs) are one of the alternatives to conventional car’s negative environmental impact. Construction of electric vehicle charging station (EVCS) emerged from the development of EVs. Distribution system power loss increases and the voltage decreases during charging of EVs. To keep the power loss as low as possible and the voltage profile healthy, proper placement of the charging station is required. In this paper, the IEEE 33 bus distribution system has been taken for finding the ideal location for EVCS placement. In order to provide EV charging in a separate area, each charging stations are allocated at three different locations. Soft Computing techniques Particle Swarm Optimization (PSO) and Symbiotic Organism Search (SOS) has been applied to find optimal placement of EVCS. The optimized results obtained by Symbiotic Organism Search (SOS) & Particle Swarm Optimization (PSO) have been compared.
