Nowadays, the world is moving towards green energy vehicles and electric (EVs) are one of chosen solutions. Vehicle-to-grid (V2G) technology gradually gaining attention to support issues performance optimization, fluctuations, reducing grid operating costs bringing optimal efficiency owners. Along with rapid increase in number EVs, deployment effective vehicle charging station (EVCS) infrastructure desirable. However, improper installation can cause many negative impacts on vice versa, especially EVCS applying V2G discharging techniques. In this study, we propose a computational model determine location size technique distribution network integrating distributed generation sources (DG) goal minimizing active power loss, using an improved method combining firefly algorithm quantum-inspired evolutionary (QBFA) find solutions for problem. The solution results simulated 33-node IEEE standard Matlab software compared original FA evaluate develop system practice.
