Özet:

A microgrid system has been designed and optimized via hybrid optimization of multiple energy resources (HOMER) software for the electricity needs of Eskisehir Osmangazi University (ESOGU). The microgrid consists of photovoltaic (PV) and wind turbine (WT) units with utility grid connection and battery energy storage system (BESS). The microgrid also supplies energy to electric vehicle (EV) charging units. The combination of EVs and renewable microgrids make a major contribution to the clean energy transition of the global energy system. It also minimizes the cost of energy (COE) and EV charging. Before analyzing the EV loads, a proper hybrid combination of the microgrid was optimized. The comparison and analysis of the proposed systems were performed according to their reliability, economic and environmental impact. The financial analysis of the winning microgrid system was carried out and its performance assessed throughout the duration of the project. Deferrable and on-demand EV charging modes were proposed in this study. To see the impact of EVs on the microgrid, various scenarios were created and applied to the design. The aim was to find a suitable charging method that uses mostly the renewable energy sources to minimize the cost of electricity while protecting the environment. This study demonstrates the importance of smart charging and how it manages charging sessions by leveraging renewable resources and charging only when electricity is at the lowest cost. The result also shows that the cost of the electricity bill of the investigated area is reduced by 36% by using the hybrid microgrid.
