Modified Perturbation and Observation Technique for Partially Shaded Photovoltaic Systems in Microgrids

Bader N. Alajmi and Faisal A. Alkandari
Abstract—A modified perturbation and observation controller for maximum power point tracking of partially shaded photovoltaic systems is proposed. The proposed controller applies scanning and storing stages to the conventional perturbation and observation technique during partial shading conditions. Moreover, the proposed system is capable to identify whether the photovoltaic system is under partial shading condition or not. The proposed system provides accurate and fast convergence to the global maximum operating point during different weather conditions. Simulation results are provided to demonstrate the validity of the controller.

Index Terms—Photovoltaic, partial shading, maximum power point tracker (MPPT), perturbation and observation.
