Abstract: Electric vehicles (EVs) are a compelling way to advance environmentally sustainable transportation systems, thanks to their potential to significantly reduce carbon emissions. Nevertheless, the seamless integration of EVs into distribution systems is fraught with challenges that require thorough investigation. With the ultimate goal of creating an ideal planning plan, the primary objective of this research is to examine electric vehicle planning strategies (EVPSs) utilizing a thorough cost and benefit analysis technique. Because EVs may operate as both a dispersed energy source and a load, they present the idea of Vehicle-to-Grid (V2G) technology. An EV with V2G technology installed can actively support the distribution system's power needs, particularly in the area of reactive power support. In order to fully benefit from integration of electric vehicles (EVs) into distribution systems, EV charging activities must be coordinated with the concurrent availability of V2G technology. This study involves the implementation of two separate PSs, each of which focuses on specific aspects of distribution system improvement. Active power distribution (APD) and reactive power distribution (RPD) are the two categories into which the strategies are separated. Their shared objective is to reduce system losses by strategically utilizing the V2G technology that is built into electric vehicles. The APD technique is predicated on the idea of minimizing losses by optimizing EV charging and discharging (CDC). On the contrary, strategy based on RPD revolves around minimizing losses through optimal charging of EVs and smart injection of reactive power into the distribution system. In addition, this research presents an in-depth cost-benefit analysis of the developed EVPSs, which provides valuable insights from a planning perspective. Finally, this study assesses how the distribution system's reorganization has improved the system's planning and operation. The effectiveness and resilience of the suggested strategy are convincingly illustrated by simulations conducted on a 33-bus distribution system, which validate these crucial observations.
