A Hybrid Power Generation With Solar and Wind System Using Multi-Level Inverter

Abstract

With the increasing concerns on energy issues, the development of renewable energy sources is becoming more and more attractive.Anew kind of wind-PV hybrid generated system that comprises of wind and photovoltaic generation subsystems as input to a cascaded H-bridge multilevel inverter is developed in this paper. In conventional methods the inverter with solar and wind energy sources are used. In this method a seven and three levelmultilevel inverter with wind–PV hybrid generation system as input are proposed for application to remote and isolated areas. The wind and the solar light are captured in greatest degree, as well as the multilevel inverter using pulse width modulation technique is adopted. The objectives of this hybrid system are, to satisfy the load power demand and, presence of high number of output levels in inverter to maintain the dc output voltage level of the inverter to produce a nearly sinusoidal output. This reduces harmonics in inverter output voltage. This paper discusses about the control of seven-level and three level H-bridge cascaded multilevel inverter with Fast Fourier Transform analysis in inverter output voltage through simulation.
