Electrification of the transportation sector is a crucial step toward achieving a sustainable society. It will lead to several advantages, such as: reduce consumption of oil, reduce emissions and integrate renewable energy resources into the grid. Deployment of electric vehicle charging stations (EVCS) is essential to encourage large adoption of Electric Vehicle (EV) as it will reduce ‘range anxiety’ concern regarding the distance the EV could travel before the battery runs out. In this work, an optimal design of an electric vehicle charging station that integrates renewable distributed generation (DG) will be designed for cost and emission reduction. Both an isolated microgrid EVCS and an EVCS connected to the grid were studied in different cases, where energy sources such as PV, wind, and diesel generator are considered to supply the EVCS demand. The model was designed using HOMER software and designed based on realistic input data in terms of physical, operational and economic characteristics.
