Robust Stability Regions for Time‐Delayed Microgrid With Superconducting Magnetic Energy Storage System Using Kharitonov’s Theorem

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Growing use of intermittent and low‐inertia renewable energy sources (RES) makes it very hard to control the frequency in current power systems. Additionally, there are unavoidable time delays when utilizing communication networks for coordination and control, and parametric uncertainties further exacerbate the stability concern.
