Advanced control of variable speed wind energy conversion system with DFIG

As a result of the increasing wind power penetration on modern power systems, the wind farms are today required to participate actively in grid operation by an appropriate generation control. This paper presents a comparative study of two control strategies for doubly fed induction generator based wind energy conversion system (DFIG-based WECS). The study focuses on the regulation of the DFIG active and reactive powers using the so-called sliding mode control and classical PI controllers. Control strategies are developed in the dq coordinates. The robustness and reliability of implemented controllers are tested with large grid disturbances due to an overvoltage and voltage sags. The DFIG control strategies are evaluated through simulations using MATLAB/SIMULINK software.
