Evaluating the impact of passenger electric vehicle adoption on high renewable resources electricity grid

Abstract

A considerable amount of electricity is additionally demanded for Electric Vehicle (EV) charging due to rapid EV penetration. This study explores the impact of time of charging for different levels of passenger EV penetration on the electricity system using a case study electricity system with high penetration of renewable energy resources. A simulation approach is proposed to determine the new demand profile due to EV charging. Next, a Mixed Integer Linear Programming model is formulated considering the operation schedules of conventional power plants to mimic the real-time status of the electricity system. Finally, the developed approach considers the different possible interventions of actual EVs available in the market and tries to determine their impact in a renewable energy-dominated electricity system. The results from the study show that it is emission-friendly to encourage night charging rather than day charging for the considered renewable energy-dominated case study electricity system.
