Grid Interface of a Pmsg Based Wind Energy Conversion System with Power Quality Improvement Features

Renewable Energy Sources are nowadays rapidly growing popularity at the distribution level which employs power electronic converters, which ensures reliable operation to customers. Among the RES, wind energy is now firmly established as a mature technology for electricity generation. This paper discusses the role of ac/dc/ac power converter for grid interface of wind energy. The generator side converter incorporates the maximum power point tracking algorithm to extract maximum energy from wind turbine system. The grid side converter plays a dual role of interfacing the wind energy to grid as well as to supply reactive power as demanded by the non-linear load connected at the PCC. A simple model of the proposed system is developed and simulated in MATLAB environment. The effectiveness of the system is validated through extensive simulation results.
