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…

Data-Driven Post-Event Analysis with Real-World Oscillation Data from Denmark
Youhong Chen, Debraj Bhattacharjee, Balarko Chaudhuri +3
This paper demonstrates how Extended Dynamic Mode Decomposition (EDMD), grounded in Koopman operator theory, can effectively identify the main contributor(s) to oscillations in pow…

A Data-Driven Method to Identify Major Contributors to Low-Frequency Oscillations
Youhong Chen, Debraj Bhattacharjee, Balarko Chaudhuri
We present a purely data-driven method to pinpoint generation plants that significantly contribute to poorly damped oscillations as part of post-event analysis. First, Extended Dyn…
