A Distributed Hybrid Controller for Photovoltaic Panel under Partial Shading Effect

In this paper, a novel method of maximum power point tracking has been proposed. The Artificial neural network (ANN) was used to generate the reference of optimal voltage. While, the Integral feedback linearization controller was designed to pursue the reference voltage generated by the ANN controller. The integral action was introduced to ensure a zero-static error. In addition, to avoid the problems of mismatching and non-uniform solar insolation, each DC/DC converter has been integrated with each photovoltaic module. This topology is called Distributed Maximum Power Point (DMPPT). The tracking performances of the proposed method were tested and validated on the MATLAB/Simulink environment.
