Implementation of Perturb and Observe MPPT Algorithm for Photovoltaic

The conventional algorithm of perturb and observe (P&O) is widely applied due to its simplicity, low cost and easy implementation. This Book presents P&O algorithm to track maximum power from solar panels under dynamic conditions. It uses a constant load technique to help the conventional P&O algorithm for recognizing the cause of power change and to enable it in taking the right decision at first step change in duty cycle during rapid change of weather. The proposed algorithm is simulated using a single solar photo voltaic module of 260 W and a DC/DC boost converter. It is validated experimentally and implemented within an DSP Processor. The experimental setup presents a proposed model-based design methodology that uses measurements' data for MPP tracking systems' design. It combines hardware-in-the-loop simulation and prototype testing using weather measurements.
