Modelling, Simulation and performance evaluation of solar PV-wind hybrid energy system

This paper describes the Simulation and analysis of hybrid energy system consisting of wind and solar PV system. The wind and solar PV system are connected to the common load through DC/DC Boost converter. Generally, in low radiation PV array system inverter gives the lower voltage than the rated voltage which affects the power quality. It is overcome by using Battery Energy Storage System. In the stand-alone mode the converter needs to maintain constant voltage and frequency regardless of load imbalance or the quality of the current, which can be highly distorted, if the load is nonlinear. The modelling and simulation of hybrid system along with the PI controllers are done using MATLAB/SIMULINK. Simulation results show that the proposed hybrid system has the potential to meet the electricity demand of an isolated system.
