In photovoltaic (PV) power generation systems, the P-V curve of PV array contains several peaks under partially shaded condition (PSC) so that conventional MPP tracking (MPPT) methods can hardly find the real MPP (MPP). This paper proposes an optimized MPPT strategy, which is not only fit for PSC but also suitable for uniform shaded conditions (USC). Comparing the optimized MPPT strategies and conventional MPPT methods, this paper illustrates the improved performance of optimized strategy under PSC. The simulation and experiment results show that the optimized strategy can track the global MPP precisely to improve the efficiency of PV systems.
