Abstract

This paper presents a modified maximum power point tracking algorithm (Modified MPPT) for PV systems based on incremental conductance (IC) algorithm. This method verified with the dynamic irradiance and sudden change of irradiance, the comparisons with conventional methods, for example, the perturbation and observation (P&O) and Modified perturbation and observation (Modified P&O) were performed. A photovoltaic (PV) panel was simulated and tested using MATLAB/Simulink based on PV panel at Power Electronics Laboratory. The results show that this method capable to find the maximum power point (MPP) under dynamic behavior faster than ( P&O) and Modified P&O). Reduced oscillation of MPP indicates enhanced efficiency, providing maximum power transfer to load
