The purpose of this paper is to propose a novel Maximum power point tracking (MPPT) technique to fully utilize photovoltaic (PV) array Output power that depends on solar insolation and ambient temperature. The proposed intelligent MPPT algorithm based on extension theory can automatically adjust the step size to track the PV array maximum power point (MMP). Compared with the conventional fixed step size perturbation and observation (P&O) and incremental conductance (INC) methods, the presented approach is able to effectively improve the dynamic response and steady-state performance of the PV systems simultaneously. Theoretical analysis and the design principle of the proposed method are described in detail. Some Simulations are performed to demonstrate the effectiveness of the proposed extension MPPT method.
