Abstract
AbstractIn this paper, solar energy has been used to generate required maximum value of power from solar photovoltaic (PV) system under partial shading condition. A simulation study of Maximum Power Point Tracking (MPPT) controller for solar PV array under partial shading condition is shown in MATLAB using the two known techniques that is conventional Perturb and Observe (P&O) and a global search algorithm Grey Wolf Optimization (GWO). The result of both the techniques are compared to show effectiveness of GWO algorithm. The proposed GWO based MPPT controller extracts the maximum amount power from the solar photovoltaic (PV) system under partial shading condition by modifying the duty cycle of Boost Converter (DC-DC). It was observed that GWO gives oscillation free maximum value of power at a faster rate as compared to conventional P&O technique.KeywordsSolar photovoltaic (PV) systemMaximum Power Point Tracking (MPPT)Perturb and Observe (P&O)Grey Wolf Optimization (GWO)
