Abstract

In this paper a comparison between three Maximum Power Point (MPP) tracking algorithms for the photovoltaic (PV) system based on: advanced Extremum Seeking (aES), modified Extremum Seeking (mES) controls, that improves the performances of the classical ES control schemes and Perturb and Observe algorithm (P&O) is proposed. The performances improvements are: higher search speed and accuracy of the MPP tracking process. So, different irradiance sequences are used to test the performances of the three proposed algorithms. Advanced Extremum Seeking control outperforms all algorithms in power efficiency.
