MPPT for a photovoltaic system under partial shaded conditions

摘要

In this paper, a method to find the maximum power point for a photovoltaic system under partial shaded conditions is presented. Furthermore, a control law using Passivity Based Control is proposed for a DC-DC converter. In addition, simulation results show the good performance of the extremum seeking control in searching the global maximum based in the inherent robustness of the Passivity Based Control.
