MPPT under partial shading conditions based on perturb & observe and incremental conductance

Abstract:Maximum power point tracking (MPPT) under uniform and different weather conditions is the main challenge in photovoltaic (PV) system. Partial shaded conditions (PSC) causes several power peaks on a P-V curve. This paper compares two powerful MPPT algorithm of Perturb & Observe (P&O) and Incremental Conductance (INC) under PSC. The PV system is developed using MATLAB simulation software with the Boost DC/DC converter interconnected. The proposed algorithms are tested under standard test and different weather conditions to prove their performance looking at their tracking speed, convergence and the settling time around the MPP
