Abstract

The Perturb and Observe (P&O) is an algorithm to find the maximum power point in the photovoltaic (PV) system. This paper presents a new method to modify the step size of P&O algorithm by categorizing the step size into the large value during the sun irradiation change where the drift occurs, the medium value when the operating point is far away from the maximum point, and the small value when the operating point is close to the maximum point. The simulation results show that the proposed method achieves the high performance in tracking the maximum power point in the terms of the fast response, the small oscillation in the steady state condition, and avoiding the drift problem. Further, the method yields the highest generated power compared to the existing techniques.
