Desertification due to global warming has a negative impact on the agricultural production capacity of hundreds of thousands of people in the world. To remedy this situation, one of the best ideas is the use of renewable energy sources to pump water and irrigate the fields. The aim of this research is the management of renewable energy hybrid power system (RE-HPS) for agricultural applications. The RE-HPS consists of a Photovoltaic (PV) system and a Wind Turbine (WT). A lead-acid battery bank is used to increase the reliability of the power system. Three Power Management Strategies (PMSs) have been evaluated on their ability to meet the requirements of the pump and loads. The dynamic behavior of the hybrid system was tested under various wind speed, solar radiation, and load demand conditions. The wind speed and solar radiation data are based on real data from Dakar in Senegal. The simulation model was developed using MATLAB/Simulinkl Stateflow. The adopted approach consists in the development of an energy management algorithm capable not only of ensuring the regulation of the water level in the reservoir but also of satisfying the demand for the load and of protecting the batteries from overcharging and deep discharging.
