Abstract

This study comprehensively analyzes the operational performance and economic feasibility of a 5MW grid-connected photovoltaic in Sudan over a two-year monitoring period. Leveraging the capabilities of PVSyst software, the actual plant performance was rigorously compared to simulation predictions. Results revealed a significant disparity between observed and simulated energy generation, prompting the exploration of potential areas for enhancement. Seasonal fluctuations in the performance ratio were evident, with peak values during some seasons, albeit not consistently aligning with simulation projections. Despite these challenges, the Plant made a notable impact by reducing CO2 emissions, highlighting the environmental benefits of solar energy. Financial analysis unveiled discrepancies between actual and simulated savings, underscoring the need for optimization and efficiency improvements. The equity payback period, influenced by electricity pricing policies, was estimated at 15 years, emphasizing its role in assessing project economics. The region's high radiation intensity and humidity levels emerged as significant factors affecting plant performance. Addressing these challenges is crucial for maximizing the PV plant's operational efficiency and viability. Our Recommendations include thoroughly examining control system functions during commissioning and improving operational accuracy.

5 MW FOTOVOLTAİK SİSTEMİN PERFORMANS İNCELEMESİ: ALFASHIR SUDAN

Abstract

Bu Makale, Sudan'daki 5MW'lık şebekeye bağlı fotovoltaik santralin çalışma performansını ve ekonomik fizibilitesini iki yıllık bir izleme süresi boyunca kapsamlı bir şekilde analiz etmektedir. PVSyst yazılımından yararlanılarak gerçek santral performansı, simülasyon tahminleriyle karşılaştırılmıştır. Sonuçlar, gözlemlenen ve simüle edilen enerji üretimi arasında önemli bir eşitsizliği göstermektedir. Performans oranındaki mevsimsel dalgalanmalar açıkça görülmektedir, her ne kadar simülasyon projeksiyonlarıyla tutarlı bir şekilde uyumlu olmasa da, bazı mevsimlerde en yüksek değerlere ulaşmaktadır. Bu zorluklara rağmen tesis, CO2 emisyonlarını azaltarak kayda değer bir etki yaratmıştır. Finansal analiz, gerçek ve simüle edilmiş tasarruflar arasındaki farklılıkları ortaya çıkararak optimizasyon ve verimlilik iyileştirmelerine olan ihtiyacın önemini göstermektedir. Elektrik fiyatlandırma politikalarından etkilenen öz sermaye geri ödeme süresi, proje ekonomisinin değerlendirilmesindeki rolü vurgulanarak 15 yıl olarak tahmin edilmiştir. Bölgenin yüksek radyasyon yoğunluğu ve nem düzeyleri, tesis performansını etkileyen önemli faktörler olarak ortaya çıkmıştır. Bu zorlukların üstesinden gelmek, PV tesisinin verimliliğini ve yaşaya bilirliğini en üst düzeye çıkarmak için çok önemlidir. Önerilerimiz, devreye alma sırasında kontrol sistemi fonksiyonlarının kapsamlı bir şekilde incelenmesini ve operasyonel doğruluğun iyileştirilmesini içermektedir.
