Electric vehicle impact on energy industry, policy, technical barriers, and power systems

Abstract

The proliferation of eco-friendly electric vehicles is becoming an irresistible trend. As governments worldwide tighten regulations on fuel efficiency and exhaust gas, the position of electric vehicles is expected to become more and more solid. The essence of this study is to cover the main components of the EV, the needed infrastructure, and investigate the impacts of the high insertion in the power systems. Moreover, this work presents an evaluation for the electric vehicles in energy distribution networks with a focus on adapting the capacity of charging stations. It was possible to process the data to confine the impact of the demand increase in distribution generators. The study allows evaluating the effect of random variables related to the distances previously traveled by vehicles and the instant of their connection to the electricity grid. These effects were compared considering these variables in deterministic terms and allowed to conclude the importance of using these more realistic methods to calculate the capacity of distributed generators to supply this new demand.
