Renewable Hybrid System with Battery Storage for Water Pumping for Small-Scale Area

The paper is devoted to a study on design, optimization and experimental study of a renewable hybrid system (photovoltaic/wind turbine) with battery storage. The design of the studied system use the total incident energy approaches to determinate the size of photovoltaic and wind generators. The simulation study has been done under Matlab/Simulink. An application to pumping water is done for four various profiles measured at Bejaia area. To control the water pumping hybrid system, a power management control has been applied to coordinate the different sources. The simulation results obtained are shown and discussed to demonstrate the applicability of the suggested system. The overall hybrid pumping system with batteries has been then investigated by an experimental study, where tests have been made during different days and under various total dynamic heads (TDH) to show the different performances as flow rate and pump efficiency variations of the proposed system. A comparison of simulation and experimental results are presented and analyzed to conclude on the feasibility of the studied system for water pumping needs applied in a small-scale area of Bejaia a Mediterranean region in Algeria.
