Sliding mode control with three-level rotor-side converters in DFIG-based wind energy systems: Comparison study

Revue des Énergies Renouvelables
This study examines a variable-speed wind energy conversion system based on a doubly-fed induction generator (DFIG). The rotor is regulated using power electronic converters, whereas the stator is directly connected to the grid.

A power system stabiliser for DFIG-based wind generation

, 2006
A power system stabilizer (PSS) for a wind turbine employing a doubly fed induction generator (DFIG) is presented. It is shown that this PSS can significantly influence the contribution that a DFIG-based wind farm can make to network damping.

Grid Voltage Unbalance and The Integration of DFIG’s

, 2013
Double-fed induction generators (DFIG’s) became the predominant generator installed for wind generation applications in the mid 1990’s. Issues pertaining to the operation and control of DFIG’s subsequently became apparent, particularly in weak areas of the grid network.
