In the multi-MW wind turbine market, the maximum power rating of a commercial wind turbine has been increased more than 5MW with a view to generate more power from Wind Power Sites [1]. The three-level neutral-point-clamped voltage-source converter has been highly applied in wind generation system. Despite the advantages, the capacitor voltage unbalancing in NPC converters has become a burning issue...
In the present scenario energy resources are being used at an alarmingly high rate. In order to ensure that younger generations are not deprived of their energy usage, India now considers wind and solar as an alternative for future energy demands. In India incidence of solar energy in land area alone is 5000 trillion kilowatt hours which exceeds the energy outcome of all possible non renewable energy...
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...
