Design and techno-economic analysis for electric vehicle charging station

Fossil fuel utilization has increased considerably over the last few decades, which has increased global warming. Developing nations face multiple challenges, and it becomes necessary to grow their economy by satisfying sustainable development goals by establishing a green energy sector. Integrated Renewable Energy Systems (IRES) are a promising solution for conventional electricity generation. The transport sector is one of the main contributors to rising emissions worldwide. Introducing electric vehicles makes developing an environmentally friendly, alternative transport sector. Infrastructure development requires significant investment and the latest technologies, a major obstacle to adopting electric vehicles. This paper proposes a standalone Integrated renewable energy system-based charging station development for electric vehicles (EV). To design, optimize and techno-economic analysis of multiple combinations of standalone integrated renewable energy systems considered. The HOMER software performs the simulations of considered systems. The optimized, integrated scheme is obtained according to economic, technical and environmental parameters for EV charging stations. The present analysis demonstrates that the optimized, integrated system provides low-cost and reliable power to fulfil the charging capacity of estimated Electric Vehicles' energy demand with the proper renewable fractions. The optimal integrated system is obtained as the combination of Solar PV, Wind Energy system, Battery Energy Storage and Diesel Generator Units for Najran City's considered location in the Kingdom of Saudi Arabia. The optimal integrated energy system for electric vehicle charging stations positively achieves sustainable electricity generation in this study, which may be a suitable future model for electric vehicle charging projects.
