Abstract: The power electronics plays an important role in the reliable operation of a modern wind energy conversion system (WECS). This study aims at the grid interconnection of a permanent magnet synchronous generator (PMSG)-based wind turbine with harmonics and reactive power compensation capability at the point of common coupling (PCC). The proposed system consists of two back-to-back connected converters with a common dc-link. The generator-side converter is used to achieve maximum power point tracking (MPPT). The grid-side converter is actively controlled to feed generated power as well as to supply the harmonics and reactive power demanded by the non-linear load at PCC, thus enabling the grid to supply only sinusoidal current at unity power factor. A model of directly driven PMSG-based variable speed WECS is developed and simulated in MATLAB/SPS environment. The effectiveness of proposed control approach is
validated through extensive simulation and experimental results.
