Improved Perturb and Observation Maximum Power Point Tracking Technique for Solar Photovoltaic Power Generation Systems

The primary concerns in the practical photovoltaic (PV) system are power reduction due to change operating conditions, such as temperature or irradiance, high computation burden modern maximum point tracking (MPPT) mechanisms, and maximize PV array output during rapid weather conditions. conventional perturb observation (P&O) technique is preferred most of systems. Nevertheless, it undergoes false (MPP) solar insolation wrong decision duty cycle. To avoid computational drift effect, this article presents a simple enhanced P&O MPPT technique. proposed by including current (dI), addition changes voltage module. effect dI profile with traditional method explained fixed variable step-size methods. mathematical expression for drift-free condition derived. boost converter considered validating effectiveness methods employing direct cycle algorithm simulated using MATLAB/Simulink validated under various scenarios developed laboratory prototype terms characteristics efficiency. result proves that can track MPP accurately
