Statistical analysis of wind energy potential for Bartın province: Weibull distribution approach

Abstract

Our study aimed to investigate the wind potential of Bartın, one of Türkiye's northernmost provinces. To determine this potential, we analyzed the region's wind power density and wind speed parameters. 3561 hourly wind speed data obtained from the stations of the General Directorate of Meteorology between the years 2015-2024 were used in the analyses.  The obtained data were evaluated to examine the annual, seasonal, and monthly distributions of wind speed. In the actual data collected, the highest wind speed was measured as 1.5645 m/s and the lowest as 0.3345 m/s. Based on the Weibull analysis, the highest average wind speed was determined to be 1.2712 m/s in 2024, and the highest power density corresponding to this average wind speed was 1.6453 W/m². The obtained data were evaluated in order to examine the annual, seasonal and monthly distributions of wind speed. Weibull distribution function, which is frequently preferred in the literature and known to provide reliable results, was used for statistical modeling of wind speeds. The shape (k) and scale (c) parameters of the Weibull distribution were determined by the least squares method; the suitability of the model was statistically verified by the coefficient of determination (R²), root mean square error (RMSE) and chi-square (χ²) tests. The analyses show that the wind data of Bartın province can be successfully represented by the Weibull distribution. The findings shed light on the feasibility of wind energy-based investments in Bartın and provide a solid data basis for new studies in this field. It is also anticipated that they may contribute to the planning of sustainable energy policies at the regional level.

Bartın ili için rüzgâr enerjisi potansiyelinin istatistiksel analizi: Weibull dağılımı yaklaşımı

Abstract

Bu çalışmada, Türkiye’nin en kuzeyinde yer alan Karadeniz Bölgesi’nin Bartın ilindeki rüzgâr enerjisi potansiyelinin belirlenmesine yönelik olarak, rüzgâr hızı ve güç yoğunluğu parametrelerinin istatistiksel analizi gerçekleştirilmiştir. Analizlerde 2015-2024 yılları arasında Meteoroloji Genel Müdürlüğü istasyonlarının saatlik olarak aldığı 
3561 adet rüzgâr hızı verileri kullanılmıştır. Elde edilen veriler, rüzgâr hızının yıllık, mevsimlik ve aylık dağılımlarını incelemek amacıyla değerlendirilmiştir. Toplanan gerçek verilerde rüzgar hızı en yüksek 1.5645 m/s, en düşük 0.3345 m/s olarak ölçülmüştür. Weibull analizi sonucunda en yüksek ortalama rüzgar hızı 2024 yılında 1.2712 m/s, bu ortalama rüzgar hızına karşılık gelen en yüksek güç yoğunluğu ise 1,6453 W/m² olarak tespit edilmiştir. Rüzgâr hızlarının istatistiksel modellemesi için literatürde sıklıkla tercih edilen ve güvenilir sonuçlar sunduğu bilinen Weibull dağılım fonksiyonu kullanılmıştır. Weibull dağılımının şekil (k) ve ölçek (c) parametreleri, en küçük kareler yöntemiyle belirlenmiş; modelin uygunluğu ise belirleme katsayısı (R²), kök ortalama kare hata (RMSE) ve ki-kare (χ²) testleri ile istatistiksel olarak doğrulanmıştır. Yapılan analizler, Bartın ilinin rüzgâr verilerinin Weibull dağılımı ile başarılı biçimde temsil edilebildiğini göstermektedir. Elde edilen bulgular, Bartın’da rüzgâr enerjisi temelli yatırımların fizibilitesine ışık tutmakta olup, bu alanda yapılacak yeni çalışmalar için sağlam bir veri temeli sunmaktadır. Ayrıca, sürdürülebilir enerji politikalarının bölgesel düzeyde planlanmasında da katkı sağlayabileceği öngörülmektedir.
