Abstract

Maximum power point tracking (MPPT) techniques are used in photovoltaic (PV) systems to maximize the PV array output power by tracking continuously the maximum power point (MPP) which depends on panel’s temperature and on irradiance conditions. For low-cost implementations, four methods are introduced in this paper in a comparative study: Hill Climbing/the perturb and observe (P&O), Incremental Conductance (IncCond), Fractional Open-Circuit Voltage and Fractional Short-Circuit Current maximum power point tracking algorithms. These are the most commonly used methods due their implementation ease. In this paper, models of different types of photovoltaic such as Single crystalline, Polycrystalline and Amorphous are implemented and compared based on their characteristics and their MPP tracking efficiency. “MATLAB R2008a” facilities are used for simulation and modeling of different methods of MPPT tracking on different types of PV models mentioned above.
