PV sistemlerinin verimliliğini ve etkinliğini artırma konusu, bu sistemleri maliyet etkin hale getirmeyi ve böylece daha geniş çapta benimsenmesini teşvik etmeyi amaçlayan araştırmacılar ve üreticiler için bir endişe kaynağı olmaya devam etmektedir. Bu amaca ulaşmak için maksimum güç noktası izleme (MPPT) sistemi kullanılarak PV üretim sisteminin verimliliğinin artırılması önerilmiştir. PV sisteminden üretilen enerjiyi artırmak, gelirleri artıracağı için verimliliği artırmada önemli bir unsur olarak kabul edilir. Sonuç olarak, üretilen enerjinin maliyeti düşmekte, bu da fosil yakıta dayalı geleneksel sistemlerden üretilen enerjinin maliyetine yaklaşmasına neden olmaktadır. Bu makale, tek tip çevresel koşullar altında çalışan PV panellerinden maksimum kullanılabilir gücü çıkarmak için tasarlanmış geleneksel MPPT tekniklerini tartışmaktadır. Daha sonra bu tekniklerin kısmi gölgeleme koşulları altında yeterli performans gösterememesinin nedeni vurgulanmıştır. Bunu takiben, kısmi gölgeleme koşulları altında çalışmak üzere tasarlanmış modern MPPT teknikleri analiz edilir.

A Review and Evaluation Study of Maximum Power Point Tracking Techniques for PV Systems

The issue of improving the efficiency and effectiveness of PV (Photovoltaic) systems remains a concern for researchers and manufacturers who aim to make these systems cost-effective, thereby encouraging their wider adoption. To achieve this goal, increasing the efficiency of the PV generation system by implementing the Maximum Power Point Tracking (MPPT) system has been proposed. Enhancing the energy output from the PV system is considered a crucial aspect of improving efficiency, as it will lead to increased revenue. Consequently, the cost of the generated energy is reduced, approaching that of energy produced by conventional systems based on fossil fuels. This review paper discusses conventional MPPT techniques designed to extract the maximum available power from PV panels operating under uniform environmental conditions. Subsequently, it highlights why these techniques often fail to perform adequately under partial shading conditions. Following this, modern MPPT techniques explicitly designed to operate under non-uniform and partial shading conditions are analyzed.
