A comparative and analytical study of various MPPT techniques applied in PV systems for fast changing environmental conditions

摘要

The amount of power generated from a photovoltaic (PV) system mainly depends on several factors, such as variations of the weather conditions (irradiation, Temperature...) and the load. According to the high cost and low efficiency of a PV system. The performance of photovoltaic systems (PV) can be improved by employing high-efficiency power control with maximum power point tracking (MPPT). This paper is aimed to study the behavior of different algorithms of maximum power point tracking (MPPT) for photovoltaic systems. These algorithms are based on the Perturb Observe (P&O), the Conductance-Increment (INC) and the sliding mode control (SMC). Simulation results show that the proposed sliding mode control (SMC) can provides faster and stable tracking maximum power as compared to the other studied methods. All the simulations work was performed on MATLAB platform.
