Subsynchronous Resonance Mitigation for Series-Compensated DFIG-Based Wind Farm by Using Two-Degree-of-Freedom Control Strategy
TL;DR: In this paper, a two-degree-of-freedom (2DOF) control strategy combined with a damping control loop is designed and analyzed for enhancing the system stability and alleviating the subsynchronous resonance (SSR) that may arise due to the induction generator effect.

Overview of emerging subsynchronous oscillations in practical wind power systems
TL;DR: The historical development of SSO definitions and classification by IEEE is reviewed, followed by discussions on recent incidents in practical wind farms due to the emerging SSO, and new terminologies and classification are proposed with the aim to better understand SSO in large-scale wind integrated power systems.
