Harmonic Mitigation In Wind Energy Conversion System By Multilevel Inverter
Wind energy source is one of the prominently renewable energy source as wind would never dies till the existence
of the universe. Previously we were using fixed speed wind turbines in wind energy conversion system (WECS), but due to
some disadvantage of fixed speed wind turbine system, we mostly used variable speed wind turbine system in most of the
places. Variable speed wind turbine uses power electronic converter in order to extract maximum power, but power
electronic converter are a source of harmonics due to its switching action. This harmonics in the voltage and current of wind
power, deteriorate the power quality of wind power. To reduce the harmonics in this WECS, several methods have been
proposed in the past so many years. This paper presents the employment of multilevel inverter to reduce harmonic.
