Abstract Emerging distribution systems accommodate a large number of dynamic devices such as distributed energy resources, their controllers and other smart devices. Complex interactions among these dynamic devices may result in a number of instability issues. One of the important instability concerns is the small signal instability caused by oscillatory modes with lower values of frequency and damping ratios. In such cases, a suitable control methodology must be applied to ensure the stability of an emerging distribution system. In this paper, a robust control methodology for a doubly fed induction generator (DFIG) is proposed for the enhancement of system stability. The impact of active and reactive power of the DFIG on a low damped mode is assessed. The effectiveness of the controller is tested in an IEEE 43 bus distribution system with distributed generation units. Results show that the proposed robust controller for the DFIG can support damping of critical modes.
