PSO Algoritması ile Optimize Edilmiş PID Denetleyicinin Fotovoltaik MPPT Sistemine Uyarlanması

Maksimum güç noktası izleme (MPPT), fotovoltaik (PV) sistemlerde, DC-DC dönüştürücülerin anahtarlama darbe genişliğini (duty cycle) değiştirerek çıkış gücünü maksimize etmek için kullanılır. Bu çalışmada, PV sistemler için parçacık sürü optimizasyon (PSO) tabanlı PID ile MPPT algoritması sunulmuştur. Önerilen yöntemin başarısını test etmek amacıyla elde edilen sonuçlar, klasik PID denetleyici ve PV sistemlerde yaygın kullanılan değiştir ve gözle (P&O) yöntemlerinin sonuçları ile karşılaştırılmıştır. Çalışmalar Matlab/Simulink ortamında gerçekleştirilmiştir. Önerilen denetim yapısının hem geçici hem de kararlı durumlarda diğer yöntemlere göre daha başarılı olduğu görülmüştür.

Adaptation of Optimized PID Controller with PSO Algorithm to Photovoltaic MPPT System

Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize output power by changing the switching duty cycle of DC-DC converters. In this work, MPPT algorithm with PID optimization based on particle swarm optimization (PSO) is presented for PV systems. In order to test the success of the proposed method, the results obtained are compared with the results of conventional PID controller and P&O methods commonly used in PV systems. The work was carried out in Matlab / Simulink environment. It has been observed that the proposed control structure is more successful than other methods in both transient and steady-state situations.
