To increase the efficiency of photovoltaic (PV) systems, maximum power point (MPP) tracking of the solar arrays is needed. Solar arrays output power depends on the solar irradiance and temperature. Also the mismatch phenomenon caused by partial shade will affect the output power of solar systems and lead to the incorrect operation of conventional MPP tracker. Under partially shaded conditions, the solar array power–current characteristic has multiple maximum. This paper presents a maximum power point tracking (MPPT) with particle swarm optimization method for PV systems under partially shaded condition. The performance of the proposed method is compared with perturb and observe (P&O), improved P&O, voltage‐based maximum power point tracking and current‐based maximum power point tracking algorithms, especially, under partially shaded condition. Simulation results confirm that proposed MPPT algorithm with high accuracy can track the peak power point under different insolation, temperature and partially shaded conditions, and it has the best performance in comparison with four mentioned MPPT algorithms. Also under rapidly changing atmospheric conditions, the P&O algorithm is diverged. Copyright © 2013 John Wiley & Sons, Ltd. A maximum power point tracking (MPPT) with particle swarm optimization method for photovoltaic systems is proposed, and its performance is compared with perturb and observe, improved perturb and observe, voltage‐based maximum power point tracking and current‐based maximum power point tracking algorithms (A sample result is shown in the figure). Simulation results confirm that proposed MPPT algorithm with more accuracy than four mentioned MPPT algorithms can track the peak power point under different insolation, temperature and partially shaded conditions.
