Abstract

In this paper, an improved perturb and observe (P&O) maximum power point tracking (MPPT) method is proposed to extract the maximum power from photovoltaic (PV) panel under rapidly changing irradiance conditions. The proposed method consists of two algorithms, namely adaptive control algorithm, and conventional P&O algorithm. The adaptive control algorithm identifies the operating limit violation
and sets a new operating point nearer to maximum power point. These operating limits are expressed in terms of the operating current range of the PV panel and the sudden changes in irradiance. The conventional P&O algorithm always tries to operate the PV panel at maximum power point (MPP). A boost converter is used to realize the proposed algorithm. The performance and efficiency of the proposed system are tested with MATLAB/Simulink software. The obtained results indicate the improved P&O method has quick respond and good stability compared to conventional P&O methods under the rapidly changing irradiance conditions.
