Abstract
This paper proposes a robust damping controller for a doubly-fed induction generator (DFIG)-based wind turbine to mitigate system oscillation during frequency response (FR) and provide robust damping performance considering uncertain system operating points. Small signal stability results of DFIG with FR controller in a single machine infinity bus (SMIB) system and a 4-machine 11-bus (4M11B) system are obtained which indicate that a new lightly damped oscillation mode is excited by the FR controller, which will lead system oscillation and deteriorate system stability. In addition to the new excited oscillation mode, the system operating points are uncertain due to power grid strength variation, power system structure change etc. Therefore, a robust damping controller is desired and proposed in this paper for DFIG equipped with FR controller. A conventional damping controller designed by residue method is also modelled in this paper. The effectiveness of the proposed robust damping controller is verified by comparing the small signal stability analysis results and simulation results to a conventional damping controller. Both small signal stability analysis results and simulation results indicate that the proposed robust damping controller shows the robust damping performance and less frequency deviation under different system operating points.
