Design of an Optimal Adoptive Fault Ride through Scheme for Overcurrent Protection of Grid-Forming Inverter-Based Resources under Symmetrical Faults

, 2023
As the integration of inverter-based resources (IBRs) is rapidly increasing in regard to the existing power system, switching from grid-following (GFL) to grid-forming (GFM) inverter control is the solution to maintain grid resilience.

A novel FRT strategy for transformerless MMC to improve current differential protection performance under single-phase grounding faults

International Journal of Electrical Power & Energy Systems
AC/DC distribution networks are interconnected by converters such as modular multilevel converters (MMCs). In AC/DC distribution networks, single-phase grounding (SPG) faults can cause enormous challenges in relay protection.

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 ...
