A Sub-Synchronous Oscillation Suppression Strategy for Doubly Fed Wind Power Generation System
IEEE Access, 2021 During the power transmission of doubly-fed induction generator (DFIG), due to the influence of series compensating capacitance and long-distance transmission, DFIG is prone to sub-synchronous oscillation, which damages the stability of the system.

A Strategy for Forced Oscillation Suppression
2024 IEEE Power & Energy Society General Meeting (PESGM), 2020 Wide-area time-synchronized measurements have recently revealed troublesome forced oscillations (FOs) within modern synchronized power grids. In some cases, these FOs represent a dangerous hazard to the system. Recent research has focused on locating the source of FOs to provide operators with knowledge for mitigating their impact locally.
