Parameterizing Operating-Point-Dependent IBR Using Coherent Operating Regions for Sub-synchronous Oscillation Analysis
Gabriel Covarrubias Maureira, Balarko Chaudhuri, Mark O'Malley
Analysis of sub-synchronous oscillations (SSO) in IBR-dominated grids relies on frequency scan-based estimation of black-box IBR models at selected operating points. Since IBRs may…

Spatial Characterization of Sub-Synchronous Oscillations Using Black-Box IBR Models
Muhammad Sharjeel Javaid, Gabriel Covarrubias Maureira, Ambuj Gupta +4
Power systems with high penetration of inverter-based resources (IBRs) are prone to sub-synchronous oscillations (SSO). The opaqueness of vendor-specific IBR models limits the abil…
