A new maximum power point tracking method for PV systems under partially shaded conditions

This paper proposes a new method which can track the maximum power under partially shaded conditions (PSC). Global maximum power (GPmax) searching method is used in this study, that is obtained by combining incremental conductance (IncCond) and scanning approach method which utilizes duty cycle sweep to track the global maximum when the PV array operates under PSC. This method is used in photovoltaic (PV) array simulation model that established in MATLAB/Simulink simulation platform. This study shows that the proposed method can track the real maximum power point accurately.
