In modern power systems, SSR is manifested as sub-synchronous control interaction (SSCI), due to adverse interactions between converter control loops and grid impedance characteristics. This paper presents a review of SSR in DFIG-based wind farms, synthesizing recent advances in mechanism identification, mitigation strategies, and detection techniques. Grid strength on SSCI susceptibility is critically examined. Mitigation approaches are comparatively analyzed across system-level, device-based, and control-based categories. Field case studies and experimental validations are reviewed to highlight real-world performance and limitations. In verified case studies, mitigation techniques like as resonant controllers, sliding mode control (SMC), and hybrid systems that combine Static Synchronous Compensators (STATCOMs) with battery energy storage (BESS) show effectiveness. Their broad implementation is hindered by enduring issues, including multimodal resonance in hybrid grids, the scalability of lab-tested solutions, cybersecurity vulnerabilities, and a lack of data for AI models. Finally, emerging trends and challenges related to adaptive control, and coordinated mitigation are discussed. The review provides actionable insights for system planners and operators seeking robust SSR mitigation in renewable-rich power systems.
