Integrating renewable energy, particularly photovoltaic (PV) systems, into the power grid presents challenges for system stability and power quality. This study proposes an innovative approach using fuzzy logic control and Lyapunov stability methods for a double-stage grid connected PV system. A dual extended Kalman filter (DEKF) accurately estimates inverter current, demonstrating improved system stability, robustness against disturbances, and superior transient response compared to conventional PI control. DEKF reduces measurement noise, leading to lower total harmonic distortion (THD) in inverter and grid currents thus improving power quality.

Włączenie energii odnawialnej, w szczególności systemów fotowoltaicznych (PV), do sieci elektroenergetycznej stwarza wyzwania dla stabilności systemu i jakości energii. W niniejszym badaniu zaproponowano innowacyjne podejście wykorzystujące sterowanie logiką rozmytą i metody stabilności Lapunowa dla dwustopniowego systemu fotowoltaicznego podłączonego do sieci. Podwójny rozszerzony filtr Kalmana (DEKF) dokładnie szacuje prąd falownika, wykazując lepszą stabilność systemu, odporność na zakłócenia i doskonałą reakcję na stany przejściowe w porównaniu z konwencjonalnym sterowaniem PI. DEKF redukuje szumy pomiarowe, prowadząc do niższych całkowitych zniekształceń harmonicznych (THD) w prądach falownika i sieci, poprawiając w ten sposób jakość energii.
