Şebekeden bağımsız hibrit sistemin (rüzgar-fotovoltaik) performans analizi

Hibrit enerji sistem tasarımında fotovoltaik panel, rüzgar türbini ve akülerin boyutlandırılması en önemli araştırma konusudur. Literatürde hybrid yenilenebilir enerji sistemlerinin boyutlandırılmasında farklı yaklaşımlar kullanan çok sayıda çalışma bulunmaktadır. Bu çalışmada, kurulan bir hibrit sistemin deneysel ve simülasyon sonuçları arasındaki farklılıklar ortaya konmuştur Yıldız Teknik Üniversite’sinde kurulan sistem 600 W rüzgar türbini, 2x320 W fotovoltaik panel ve 4x210 Ah akü içermektedir. Maksimum güç noktası takip kontrol cihazı, hibrit kontrolcü ve inverter sırasıyla panel, türbin ve çıkış gücü kontrolü için kullanılmıştır. Hava istasyonu rüzgar hızı, sıcaklık, ışınım gibi hava verilerini kaydetmek için ve veri kaydedici de elektriksel büyüklükleri kayıt altına almak için kullanılmıştır. Sistem kullanılan bileşenlerin katalog bilgilerine göre modellenmiştir ve modelleme sonuçları ile uygulama sonuçları karşılaştırılmıştır.

Performance analysis of stand-alone hybrid (wind-photovoltaic) energy system

Sizing of PV panel, wind turbine and storage batteries in hybrid energy systems is the most important research topic for a system design. There are many studies in the literature, using different approaches about sizing of hybrid renewable energy systems. In this study, experimental and simulation performance differences of the installed hybrid system are presented. The system that is installed in Yildiz Technical University, has 600 W wind turbine, 2x320 W photovoltaic (PV) panel group and 4x210 Ah batteries. A maximum power point tracking (MPPT) controller, a hybrid controller and an inverter are utilized to control the panels, wind turbine and power flow. A weather station is used to measure the weather conditions such as wind speed, temperature, radiation, and electrical quantities are recorded by a data logger. The system is modelled depending on the datasheets of the components, and the modelling results are compared with experimental results.
