Design and simulation of solar and wind energy conversion system in isolated mode of operation

This paper presents design and simulation of PV (Photovoltaic)and wind hybrid Energy system (WECS) in isolated mode of operation. The output voltage from two sources are given to DC link by using to DC-DC converters in order to maintain constant DC link voltage. Single phase Inverter with unipolar voltage switching is used. The Total Harmonic Distortion (THD) of load voltage is analyzed. This work presents results based on realistic data as inputs obtained from the operation of a test workbench consisting PV-Wind hybrid system. The system includes a 3KW PV array and 3.2KW wind turbine; realistic data for January 2013 obtained from the Innovation Centre, MIT Manipal, is considered here, simulated daily data, and validated the simulation results for the physical system.
