Ferromagnetically Shielded Fault Current Limiter (FS‐FCL) Evaluation in Power Line

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study introduces a new ferromagnetically shielded FS‐FCL design and its control strategy for limiting and interrupting fault currents. The fully shielded core structure enhances inductance and prevents saturation, enabling an immediate fault response without causing voltage drop during normal conditions.

Multi‐Layer MTDC Protection: Design and Simulation Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...

Non‐Contact Turn‐Off Time Measurement Method for IGBTs in the Half‐Bridge Submodule Configuration of MMC

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a non‐contact method for measuring the turn‐off time of insulated‐gate bipolar transistor (IGBT) devices in modular multilevel converters (MMC) submodules, using the decay of load‐side common‐mode current. The technique leverages existing current‐sensing infrastructure and avoids intrusive modifications, enabling real‐time ...

Wide‐area damping control in renewable integrated power systems: A review on recent achievements and new challenges

Energy Conversion and Economics, Volume 6, Issue 6, Page 341-358, December 2025.
Abstract Low‐frequency oscillations (LFOs) remain a major obstacle to maintaining stable dynamic performance in power systems with high levels of renewable energy integration. In particular, inter‐area LFOs have emerged as a critical concern in large, interconnected grids.
