Fuzzy Optimization of a Photovoltaic Pumping System: Implementation and Measurements

Hichem Othmani

Abstract


This paper presents a fuzzy logic optimization a photovoltaic pumping system. In this study, a photovoltaic source is connected to a three phase inverter which supplies an induction motor-pump. In addition to the induction motor pump, the hydraulic part of this system contains two communicating tanks. The effectiveness of these systems depends on the adequacy between the generated electrical energy and the quantity of the pumped water. Our designed strategy aims to exploit the maximum of the available energy whatever the climate conditions to pump water. Measurements made on the studied system demonstrate that the designed approach improves the efficiency.
