Robust Online Stability Margin Monitoring of Grid‐Connected Inverters via Current‐Ratio‐Based Rational Algebraic Stability Criterion

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
A robust online stability‐margin monitoring framework is proposed for grid‐connected inverters. A current‐ratio‐based measurement scheme improves the signal‐to‐noise ratio without high‐bandwidth voltage sensors, while a Rational Algebraic Stability Criterion (RASC) decouples the gain‐ and phase‐margin constraints.
