Performance Evaluation of Hybrid Photovoltaic-wind Power Systems

This paper presents experimental results from the operation of a test bench constituted of a PV-Wind hybrid system. This device includes photovoltaic (PV) and wind subsystems, battery energy storage, load and a hybrid system, controller for battery charging and discharging condition. The system includes a 600W PV array, 1KW wind turbine; in the day the energy produced is stored in a battery bank 24 V/1600Ah and used for public lighting at night, with an average daily energy consumption of 2640 Wh. The experimental set up has been realized in the Research Unit in Renewable Energies in Saharan Medium, Adrar (South of Algeria). The photovoltaic panel group constitutes the primary energy supplier of the system; while the wind turbine is the secondary supplier since the contribution of wind turbine is small as compared to the share of the photovoltaic subsystem.
