COMPARATIVE STUDY OF IC, P&O AND FLC METHOD OF MPPT ALGORITHM FOR GRID CONNECTED PV MODULE

The photovoltaic (PV) system is one of the renewable energies that attract the attention of researchers in the recent decades. The PV generators exhibit nonlinear I-V and P-V characteristics. The maximum power produced varies with both irradiance and temperature. Since the conversion efficiency of PV arrays is very low, it requires maximum power point tracking (MPPT) control techniques. The purpose of this paper is to study and compare three maximum power point tracking (MPPT) methods in a photovoltaic simulation system using perturb and observe method, Incremental conductance method and Fuzzy Logic Control method. MATLAB/Simulink used to establish an Implementation of MPPT Algorithm for Grid Connected PV module. This system is developed by combining the models established of solar PV module &MPPT, DC-DC Boost converter, DC/AC converter. The system is simulated under different irradiation (between 250 W/m2and 1000 W/m2). Simulation results show that the photovoltaic simulation system can track the maximum power point accurately.
