Optimal Pricing of EV Charging Station Services to Improve Technical Issues Considering Traffic Constraints

Due to increasing air pollution and fuel supply problems, the use of electric vehicles has been considered as a clean alternative to traditional cars. Extensive studies have been conducted on the environmental effects of these cars and their benefits in reducing air pollution have been proven. However, the high penetration of electric vehicles can create new challenges in the power system, especially concerning their charging demands. The change in demand due to electric vehicles creates challenges and concerns for the electric system. The electrical system must be ready to respond to a new load called “the demand for electric vehicles”. In this paper, by providing the optimal charging price and considering traffic restrictions, remained charging limits and charging rates, it is possible to choose the right charging station. This action reduces the possibility of damage to the network and leads to the improvement of network technical parameters, including losses and voltage profile. The results shows the effectiveness of the model.
