| Abstract |
A photovoltaic (PV) array show multi local maximum power points mode under partially shaded conditions, where the operating point of the PV system tends to converge to a local maximum power point (LMPP) which is not the real maximum power point. A novel MPPT method is proposed in this paper to achieve global maximum power point tracking (GMPPT) under partially shaded conditions. The behavior of I-V characteristics is discussed and interval short-circuit current is applied to locate global maximum power point interval. A state-space based PV array model and simulation results are presented to validate the proposed method. |
