Plug-and-Play Stability Certificates Compliant with Black-Box Models of Devices
Petr Vorobev, Andrey Gorbunov, Youhong Chen +2
This paper presents a new approach to the derivation of decentralized plug-and-play stability certificates that can be calculated using black-box admittance spectra, without requir…
Decentralized Stability of IBR-dominated Power Grids Using Block Diagonal Dominance
Youhong Chen, Xiaoyu Tan, Muhammad Sharjeel Javaid +2
The growing penetration of inverter-based resources (IBRs) necessitates stability assessment methods that are scalable, decentralized, and model-agnostic. This paper develops a blo…
Dynamic Passivity Multipliers for Plug-and-Play Stability Certificates of Converter-Dominated Grids
Andrey Gorbunov, Youhong Chen, Petr Vorobev +2
Ensuring small-signal stability in power systems with a high share of inverter-based resources (IBRs) is hampered by two factors: (i) device and network parameters are often uncert…
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…
