Abstract

Fotovoltaik (PV) sistemler ucuz, kurulabilir alanlarının fazla olması, çevre dostu ve enerji verimliliği gibi doğal avantajları nedeniyle dünyadaki en önemli enerji kaynaklarından biri olarak kabul edilmektedir. Güneş PV sisteminin çıkış gücünü artırmak için, mümkün olan en yüksek maksimum güç noktası izleme (MPPT) algoritması, fotovoltaik (PV) üretim sisteminin performansını optimize etmede önemli bir rol oynar. Bu makalede yaygın olarak kullanılan Değiştir & Gözlemle (Perturb and Observe (P&O)) yöntemini ve Artan İletkenlik (Incremental Conductance (IC)) yöntemlerinin hem deneysel hemde Matlab/Simulink benzetim modeli kullanılarak kapsamlı bir değerlendirilmesi sunulmuştur. Deneysel çalışmalar Arduino Uno kullanılarak 1 Khz PWM çıkışı ile gerçekleştirilmiştir. Konvertör yapısı olarak Boost konvertör kullanılmıştır. Elde edilen deneysel sonuçlar InC yönteminin ani değişen ışınım altında P&O algoritmasına göre daha iyi yakınsama ve daha yüksek doğrulukla maksimum güç noktasını tespit edebildiğini göstermektedir.

Experimental Analysis of Perturb and Observe (P&O) and Incremental Conductance (InC) Algorithms for Maximum Power Point Tracking in Photovoltaic Systems

Abstract

Photovoltaic (PV) systems are considered as one of the most important energy sources in the world due to their inherent advantages such as cheap, large installable area, environmental friendliness and energy efficiency. To increase the output power of the solar PV system, the maximum possible maximum power point tracking (MPPT) algorithm plays an important role in optimizing the performance of the photovoltaic (PV) generation system. This paper presents a comprehensive evaluation of the widely used Perturb and Observe (P&O) and Incremental Conductance (IC) methods using both experimental and Matlab/Simulink simulation models. Experimental studies were carried out using Arduino Uno board with 1 Khz PWM output. Boost converter was used as the converter structure. The experimental results show that the InC method is able to detect the maximum power point with better convergence and higher accuracy than the P&O algorithm under sudden changing irradiance.
