Predicting the Fault‐Ride‐Through Probability of Inverter‐Dominated Power Grids Using Machine Learning

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
We present the first comprehensive demonstration of machine learning's potential in probabilistic dynamic stability analysis for power grids, using fault‐ride‐through probability as a practical metric. Our ML models, trained on synthetic grid simulations, accurately predict stability outcomes and component criticality while generalizing well to ...

Sub‐Synchronous Oscillation in Offshore Energy Islands With MMC‐HVDC Links: Mechanism, Analysis and Mitigation

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper investigates the small‐signal stability of offshore energy islands interconnected by multiple MMC‐HVDC links and reveals a previously unreported sub‐synchronous oscillation (SSO) mechanism caused by multi‐converter coupling through the offshore AC network.

Strengthening Renewable‐Rich Weak Grids Through Improved Voltage Stability and Fault‐Ride Through Capability

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
To enhance grid stability and resilience in high renewable energy scenarios, this research proposes a cascaded control optimization framework guided by a novel dynamic resilience metric. Validated on a representative Australian grid, the framework significantly reduced voltage overshoot and extended fault clearing times, offering a robust solution for ...
