Decentralized Stability Certificates in IBR-Dominated Grids: The Role of the Network State
Zhimeng Wang, Sushobhan Chatterjee, Sijia Geng, Richard Pates, Enrique Mallada
Small-signal instabilities, such as unforced sub-synchronous oscillations (SSOs), are increasingly observed in inverter-based resource (IBR) dominated grids. While decentralized stability certificates offer a scalable means to avoid instability onset, they are typically derived u…
