Fuzzy Energy Management for Photovoltaic Water Pumping System

Abstract

A Fuzzy energy management algorithm for a photovoltaic water pumping installation is presented and validated experimentally, using a plant composed of photovoltaic panels, battery banks, DC/AC converters, relays and a water pump.Considering many criteria related to the battery safe operation, fulfilling the water volume needed by the crops and ensuring a continuous function of the pump, the algorithm decides the switching of the relays, which link the installation' components.The algorithm is evaluated for a specific case study: tomato irrigation in Tunisia.Obtained results confirm that the irrigation water demand is covered during the season with a minimum use of the battery.
