This paper suggest a control strategy to enhance the LVRT capability of doubly fed induction generator (DFIG) based wind turbine system using dynamic voltage restorer (DVR). Wind should support grid during fault time. The method used here is series compensation at point common coupling on occurrence maintain stator constant. performance improved by optimization PI parameters particle swarm as c...

For the extraction of wind energy through a doubly-fed induction generator (DFIG), low voltage ride (LVRT) is an essential technical requirement specified by transmission system operator (TSO). Under grid fault condition, DFIG should remain in connection with for certain minimum period and offer reactive power support as required TSO. A cooperative control scheme consisting hardware solution su...

This paper presents a new nonlinear backstepping controller for a direct-driven permanent magnet synchronous generator-based wind turbine, which is connected to the power system via back-to-back converters. The proposed controller deals with maximum power point tracking (MPPT) in normal condition and enhances the low-voltage ride-through (LVRT) capability in fault conditions. In this method, to...
