Abstract

This paper presents a novel scheme of Permanent Magnet Synchronous Generator (PMSG) based Wind Energy Conversion System (WECS) using pitch angle control and Z source DC-DC control. This is proposed along with AC-DC-AC converter system which is voltage source converter to smooth fluctuations in output power generated due to change in wind speed. The fluctuations in output power consists of lower order harmonics and shootouts to eliminate these Z source DC-DC converter is used and pitch angle controller is designed to change blade angle of wind turbine so as to extract maximum power from wind due to disturbances existing in wind energy which is described using Power Coefficient (Cp). The proposed model is designed in MATLAB and simulation results are presented.
