Stability Analysis in IBR-Dominated Grids: Model-Based and Data-Driven Methodologies
The paper explores stability issues in grids dominated by Inverter-Based Resources (IBR), which involve static, small-signal, and large-signal dynamic instabilities that are interconnected. It examines how traditional model-based tools and emerging data-driven methods can analyze these phenomena. The study highlights the challenges of data completeness and physical interpretability when using AI to model complex IBRs.
