The Shading Effect on Photovoltaic Generator (GPV) Based on Reverse Osmosis (RO) Desalination System in Algeria

This paper investigates the performances analysis of PV-RO desalination system under uniform and non-uniform irradiance conditions. The main objective is application Extremum Seeking Control (ESC) to GPV side in order overcome generated power water quantity losses improve performance whole system. technical design developed based on an existing RO unit beside that real climatic data taken from a local mast are involved this study. modeling control techniques adopted study fully formulated. modeled controlled using MATLAB/Simulink. Different scenarios (healthy shaded) have been used carry out results. ESC shows its effectiveness extract maximum shaded conditions for all proposed scenarios. Compared with conventional controllers, technique can offer extra surrounding 685W several cases. Furthermore, shading affect widely freshwater production whose estimated at around 82.91% critical findings results very significant industrialists working field.
