In this paper, a new hybrid algorithm for photovoltaic (PV) maximum power point tracking (MPPT) under partial shading conditions is proposed. This algorithm is a mix between conventional perturb and observe (P&O) and fuzzy logic control (FLC) PV MPPT algorithms. The main idea of the proposed algorithm is starting MPPT with P&O and switching to FLC algorithm when the transient operating point is close to the global maximum power point (MPP). According to simulation results, in comparison with individual P&O and FLC MPPT algorithms, by using the proposed MPPT algorithm, more energy can be harvested.
