Fuzzy Logic Optimization of a Centralized Energy Management Strategy for a Hybrid PV/PEMFC System Feeding a Water Pumping Station

Abstract

This paper shows a developed fuzzy logic supervisor used to manage energy flow in a hybrid renewable energy system composed of a photovoltaic generator and a proton exchange membrane fuel cell. The hybrid installation is used to feed a pumping system used to store water in a tank in order to use it whenever needed. This system is widely used especially for agriculture purposes but batteries are used to maintain continuous water pumping when the solar irradiance quantity is not enough for the photovoltaic generator to provide needed power for the pumping system. The proposed solution guarantees continuous power production and water availability with the least possible costs thanks to the developed management strategy. The obtained results prove the efficiency of the studied technique in reducing fuel consumption by minimizing its utilization as maximum as possible and that continuous water pumping process is guaranteed.
