MPPT algorithm control for grid connected PV module

This work presents a comparison of several methods of tracking the maximum power point (MPPT) to extract the maximum power and improve the control performance of a photovoltaic system. The control techniques most used in MPPT control are reviewed, studied and developed such as: observation and perturbation (P&O) [1] and conductance increment (INC), Fuzzy Logic Control (FLC). The simulation results of these algorithms are interpreted by Matlab-Simulink, The three methods are used with a DC / DC converter “Boost” linked to the utility grid.
