ŞEBEKEYE BAĞLI RÜZGAR-GÜNEŞ-HİDRO-PİL HİBRİT ENERJİ SİSTEMİNİN OPTİMAL BOYUTLANDIRILMASI VE TEKNO-EKONOMİK ANALİZİ

Öz

Hibrit mikro şebeke sistemleri, yenilenebilir enerji kaynaklarını kullanarak fosil yakıt bağımlılığını azaltan sürdürülebilir ve düşük emisyonlu bir alternatif olarak öne çıkmaktadır. Literatürdeki çalışmaların büyük bölümü güneş ve rüzgâr odaklı hibrit sistemlere yönelirken, bu çalışmada Kırıkkale’de 1.000 hanelik bir yerleşimin elektrik ihtiyacını karşılamak amacıyla rüzgâr, güneş ve hidroelektrik kaynakları birlikte hibrit yapıya entegre edilmiştir. Ayrıca sisteme şebeke bağlantısı ve batarya depolama birimleri eklenerek daha kapsamlı bir modelleme gerçekleştirilmiştir. Bu doğrultuda sistemin teknik ve ekonomik uygulanabilirliğini incelemek için HOMER Pro yazılımı kullanılmış, farklı senaryolar altında hibrit sistemin performansı değerlendirilmiş ve çok amaçlı bir optimizasyon yapılmıştır. Optimizasyonun temel amacı, yük talebini güvenilir şekilde karşılamak, yenilenebilir enerji kullanımını en üst düzeye çıkarmak ve toplam sistem maliyetini en aza indirmektir. Güneş ve rüzgâr verileri NASA veri tabanından, hidrolojik veriler ise DSİ ölçümlerinden alınmıştır. Yapılan analizler sonucunda en uygun senaryo; 3,47 milyon $ Net Bugünkü Değer, 0,0252 $/kWh Dengelenmiş Enerji Maliyeti, %91,5 yenilenebilir enerji kullanımı ve 8,60 yıl geri ödeme süresi ile elde edilmiştir. Ayrıca sistemin yıllık CO₂ emisyonlarını 3.585.533 kg azalttığı belirlenmiştir. Bu sonuçlar, Kırıkkale’de yenilenebilir temelli hibrit mikro şebekelerin teknik ve ekonomik açıdan uygulanabilir olduğunu göstermektedir.

OPTIMAL SIZING AND TECHNO-ECONOMIC ANALYSIS OF A GRID-CONNECTED WIND–SOLAR–HYDRO–BATTERY HYBRID ENERGY SYSTEM

Abstract

Hybrid microgrid systems offer sustainable and low-emission solutions that reduce dependence on fossil fuels by integrating renewable energy resources. While most studies focus on solar–wind-based hybrid structures, this study examines a more comprehensive configuration by integrating wind, solar, and hydroelectric resources to meet the electricity demand of a 1,000-household settlement in Kırıkkale. The system also includes grid connection and battery storage units. To evaluate its technical and economic feasibility, HOMER Pro software was used, and multiple scenarios were analyzed through a multi-objective optimization approach. The main goals were to reliably meet the load demand, maximize renewable energy utilization, and minimize total system cost. Solar and wind data were obtained from the NASA database, while hydrological data were sourced from DSI measurements. The optimal scenario achieved a Net Present Value of 3.47 million USD, a Levelized Cost of Energy of 0.0252 USD/kWh, a renewable penetration rate of 91.5%, and a payback period of 8.60 years. The system is also estimated to reduce annual CO₂ emissions by 3,585,533 kg. These findings indicate that renewable-based hybrid microgrids are technically and economically viable for Kırıkkale and can serve as a reference model for regions with similar resource characteristics.
