Abstract:

 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.

 Eskişehir Osmangazi Üniversitesinin ESOGU elektrik ihtiyacı için çoklu enerji kaynaklarının hibrit optimizasyonu HOMER yazılımı ile bir mikro şebeke sistemi tasarlanmış ve optimize edilmiştir. Mikro şebeke, elektrik şebekesi bağlantılı ve batarya enerji depolama sistemine BESS sahip fotovoltaik PV ve rüzgâr türbini WT ünitelerinden oluşmaktadır. Mikro şebeke ayrıca elektrikli araç EV şarj ünitelerine enerji sağlamaktadır. EVler ve yenilenebilir mikro şebekelerin kombinasyonu, küresel enerji sisteminin temiz enerji geçişine büyük katkı sağlamaktadır. Ayrıca enerji maliyeti COE ve EV şarjını da en aza indirmektedir. EV yüklerini analiz etmeden önce, mikro şebekenin uygun bir hibrit kombinasyonu optimize edilmiştir. Önerilen sistemlerin güvenilirliği, ekonomik ve çevresel etkilerine göre karşılaştırılmış ve analizleri yapılmıştır. Kazanan mikro şebeke sisteminin finansal analizi yapılmış ve proje süresince performansı değerlendirilmiştir. Bu çalışmada ertelenebilir ve isteğe bağlı EV şarj modları önerilmiştir. EVnın mikro şebeke üzerindeki etkisini görmek için çeşitli senaryolar oluşturulmuş ve tasarıma uygulanmıştır. Amaç, çevreyi korurken elektrik maliyetini en aza indirmek için çoğunlukla yenilenebilir enerji kaynaklarını kullanan uygun bir şarj yöntemi bulmaktır. Bu çalışma, akıllı şarjın önemini ve yenilenebilir kaynaklardan yararlanarak ve yalnızca elektrik en düşük maliyette olduğunda şarj ederek şarj oturumlarını nasıl yönettiğini göstermektir. Sonuç ayrıca, hibrit mikro şebeke kullanılarak incelenen alanın elektrik faturasının maliyetinin 36 oranında azaldığını göstermektedir.
