- This paper studies the maximum power point tracking (MPPT) methods under partially shaded conditions for a stand-alone PV array system. The rules for judging partially shaded conditions are presented and integrated into four MPPT methods. These methods are tested in real-time simulation environment, and their advantages and disadvantages are further analyzed. Matlab/Simulink/SimPowerSystems are used with RT-Lab for building the real-time simulation models and the MPPT controller for partially shaded conditions. Based on the simulation results, the MPPT methods integrated with judging rules for partially shaded conditions can track the maximum power point better than those without judging rules, elevating the usage efficiency of PV arrays.
