Modelling of an Electric Vehicle Charging Station Incorporating Optimal Sizing and Cost

Abstract

Renewable energy systems are becoming more and more common as people turn away from conventional energy sources. Microgrids are incorporated with renewable energy sources as they guarantee an economically and environmentally sound solution. The main problem arises when electric vehicle charging stations are integrated with microgrids. It would be required for the microgrid to have a synchronized and optimal charging system in order to accommodate several EVs. Using the HOMER Grid software, various configurations are simulated in this paper. Various renewable energy sources, tariff plans, and size of the components are used to create the configuration to determine the system that performs the best economically and environmentally. With regard to factors such as annual energy costs, cost reductions, and carbon emissions, among other things, a comparison of the current system with the optimized system is performed. As a result, the NPC, O&M and LCOE of the system decreased by ₹ 2.56M, ₹ 4.52L, and ₹ 4.03 respectively and the carbon emissions got reduced significantly.
