Simulation and Comparative Practical Performance Analysis Of A Stand-Alone PV Power System in Gökçeada

Abstract

This study simulates and analyzes the practical performance of a 2 kW stand-alone PV power system located in Gökçeada/Turkey. System performance was calculated both by simulation and real life measurements. Although the total system efficiency and the performance ratio is simulated 5 % and 41 %, these values are calculated averagely during the real-life monitoring period as 4 % and % 32.4 respectively. The results were reported using the international evaluation parameters. The main reasons of the difference between the simulated and practical calculated values are the partial shadow effects and the limited energy generation due to the low load demand.

Gökçeada'da Şebekeden Bağımsız Bir Fotovoltaik Güç Sistemi Benzetimi ve Karşılaştırmalı Gerçek Performans İncelemesi

Abstract

Bu çalışmada, Gökçeada/Türkiye'de yerleşik ve şebekeden bağımsız 2 kW anma gücündeki bir fotovoltaik (FV) güç sisteminin benzetim ve uygulamalı başarım analizi yapılmaktadır. Sistemin başarımı, hem benzetim hem de gerçek zamanlı ölçüm değerleri kullanılarak incelenmiştir. Benzetim çalışmasından hesaplanan % 5 sistem verimi ve % 41 gerçekleme oranı parametreleri, gerçek çalışma koşullarında izleme dönemi ortalaması olarak sırasıyla % 4 ve % 32,4 olarak gerçekleşmiştir. Bu çalışmada, uluslararası değerlendirme parametreleri dikkate alınmıştır. Benzetim ve gerçek zamanlı başarım değerleri arasındaki farkın temel gerekçesi kısmi gölge etkileri ve belli dönemlerde düşük yük talebinin üstünde üretilen enerjinin sınırlanması olarak gözlenmiştir.
