Guidance model for EV charging service

High Electric Vehicle (EV) penetration increases smart grid solicitation especially with various EV charging demands at peak load times. The EV charging process at public supply station (EVPSS) has to be managed in the way to promote the EV satisfaction levels while preserving smart grid stability. The waiting time for the EV charging service is an important factor in assessing the effectiveness of any interaction system between EVs and smart grid. In this paper, we present a system-guidance model to minimize the waiting time for an EV to be plugged-in for the charging service at public supply stations. We propose an algorithm for directing vehicles to charging stations in a way to minimize their searching time to join a supply station. The simulations conducted to evaluate its performance while satisfying the defined constraints proved the effectiveness of the proposed approach.
