KÜÇÜK ÖLÇEKLİ ADA TİPİ PV (FOTOVOLTAİK) SİSTEMLERİNİN REAKTİF GÜÇ KOMPANZASYONU TABANLI OPTİMİZASYONU

Endüktif karakterli olan yükler; enerji kaynağından hiçbir şekilde işe dönüşmeyen, sistem donanımları üzerinde olumsuz sonuçlar doğuran ve fazladan termal enerji açığa çıkaran reaktif güç talebinde bulunurlar. Reaktif gücün sistemde yarattığı olumsuz etki, reaktif güç kompanzasyonu ile güç katsayısı kontrolü gerçekleştirilerek minimumda tutulur. Bu çalışmada, bir PV sisteme reaktif güç kompanzasyonu kontrolü yapılarak sistemde genel olarak performans optimizasyonu gerçekleştirilmiştir. Çalışma kapsamında, dizayn edilen sistemin ana bileşenlerinin matematiksel modellemeleri gerçekleştirilerek MATLAB kodları, Simulink modellemeleri marifetiyle performans simülasyonları yapılmıştır. Deneysel uygulamadan elde edilen veriler ile simülasyon esaslı performans verileri karşılaştırılmıştır. Çalışma sonucunda, sistemin akım taşıma kapasitesi artırılmış, termal enerjide bir azalma elde edilmiş, dolayısıyla sistem performansının optimizasyonu sağlanmıştır.

REACTIVE POWER COMPENSATION BASED OPTIMIZATION OF MICRO-SCALE STAND-ALONE PHOTOVOLTAIC SYSTEMS

Inductive loads demand reactive power that does not turn into useful energy from the energy source, adversely affects system components, and releases excessive thermal energy. The control of the power factor (cos φ) decreases the negative effect of reactive power in the system by performing reactive power compensation (RPC). In this study, RPC is applied to a Photovoltaic (PV) system to increase the overall system. The designed system's main components' mathematical modeling and performance simulations are made using MATLAB codes and Simulink modellings. Simulation-based performance data were compared with the data obtained from the experimental setup. As a result of the study, the system's current-carrying capacity (CCC) is increased, a reduction in thermal energy is obtained; therefore, the system performance is optimized.
