Modeling and Optimization of a Photovoltaic Generator with Matlab/Simulink

The output power of a photovoltaic generator isrelated to many climatic factors like temperature and solarillumination; it is then necessary to track the maximum powerpoint in real time to optimize the photovoltaic system efficiency.This work presents the modeling of a photovoltaic system with amaximum power point tracking (MPPT).The operating of the photovoltaic system and the improvementof its efficiency taking into account rapid variations ofmeteorological conditions is presented with a MPPT based onperturb and observe (P&O) strategy, both implemented usingMatlab. Simulation results showed that operating point oscillatesaround maximum power point and these oscillations areproportional to the variations of the incident illumination.
