Performance analysis of a stand-alone hybrid renewable energy power system- a simulation study

This paper analyzes the performance, through simulation, of a renewable energy based hybrid power system consisting of photovoltaic cells, wind turbine, battery energy storage system, and diesel generator system. Three cases viz. i) variation of load ii) variation of wind speed and iii) variation of solar irradiance have been considered for performance analysis. The battery energy storage system and diesel generator, integrated into the hybrid power system, help mitigate the effects of intermittent fluctuations due to varying weather conditions that affect the output of wind turbine and photovoltaic cells. The simulations are carried out in MATLAB/Simulink environment.
