Energy, Economic and Environmental Evaluation of Vertical Axis Wind Turbine for Urban Applications: A Case Study of Dogus University

Abstract

This study provides a comprehensive energy, economic, and environmental analysis of a commercial vertical-axis wind turbine (VAWT) for urban-scale applications. In accordance with the objective of this study, Doğuş University has been considered as a case study for conducting these analyses. In the analyses, wind speed data obtained from the meteorological station closest to the university, along with the technical specifications of a commercial vertical-axis wind turbine with a rated power of 5 kW, were considered as the basis. In the energy analysis, the amount of electricity generated by the turbine is calculated, while the economic analysis determines the revenue from electricity production, the additional revenue from the reduction of greenhouse gas emissions, and the total annual revenue. Additionally, the environmental analysis evaluates the potential for CO₂ emissions reduction. As a result of the study, the power density was calculated as 41.76 W/m² and 41.3 W/m², based on the Weibull distribution and meteorological data. Furthermore, calculations for a single wind turbine indicated that 2062.6 kWh of electricity production and a reduction of 947.98 kg of CO₂ emissions could be achieved in 2024. From an economic perspective, the total annual revenue is determined to be $241.10, with a Levelized Cost of Energy (LCOE) of 0.193 $/kWh. Based on the findings, it is believed that this study can play a guiding role in the planning and evaluation of wind energy systems for similar buildings and urban areas.

Kentsel Uygulamalar İçin Dikey Eksenli Rüzgâr Türbininin Enerji, Ekonomik ve Çevresel Değerlendirmesi: Doğuş Üniversitesi Örneği

Abstract

Bu çalışma, kentsel ölçekli uygulamalar için ticari bir dikey eksenli rüzgâr türbini (VAWT) üzerinden kapsamlı bir enerji, ekonomik ve çevresel analiz sunmaktadır. Bu çalışmanın amacı doğrultusunda, Doğuş Üniversitesi, bu analizlerin gerçekleştirildiği bir durum çalışması olarak ele alınmıştır. Analizlerde, üniversiteye en yakın meteorolojik istasyondan elde edilen rüzgâr hızı verileri ile 5 kW nominal güce sahip ticari bir dikey eksenli rüzgâr türbininin teknik özellikleri temel alınmıştır. Enerji analizinde, türbinden elde edilen elektrik miktarı hesaplanmış, ekonomik analizde ise elektrik üretiminden sağlanan gelir, sera gazı emisyonlarının azaltılmasından elde edilecek ek gelir ve toplam yıllık gelir belirlenmiştir. Ayrıca, çevresel analizde CO₂ emisyonlarının azaltılma potansiyeli değerlendirilmiştir. Çalışma sonucunda, Weibull dağılımı ve meteorolojik verilere dayanarak güç yoğunluğu sırasıyla 41,76 W/m² ve 41,3 W/m² olarak hesaplanmıştır. Ayrıca, tek bir rüzgâr türbini üzerinden yapılan hesaplamalar, 2024 yılı boyunca 2062,6 kWh elektrik üretimi ve 947,98 kg CO₂ emisyonu azaltımı sağlanabileceğini göstermektedir. Ekonomik açıdan, toplam yıllık gelir 241,10 $ ve seviyelendirilmiş enerji maliyeti (LCOE) 0,193 $/kWh olarak belirlenmiştir. Elde edilen bulgulara dayalı olarak, bu çalışmanın benzer binalar ve kentsel alanlar için rüzgâr enerjisi sistemlerinin planlanması ve değerlendirilmesinde yol gösterici bir rol üstlenebileceği düşünülmektedir.
