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 ...

Modular Fault‐Limiting and Ride‐Through Coordination for Cost‐Effective Protection of LVDC Distribution Networks

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a modular fault‐limiting strategy that integrates multi‐port modules with DC circuit breakers to enhance system regulation. This coordination enables the use of cost‐effective mechanical breakers while significantly improving the fault‐ride‐through capabilities of the distribution network.

Enhanced Control Strategies Temporal Coordination Based on Transmitted Active and Reactive Power during Commutation Failure Recovery

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper first identifies the common issue across multiple LCC‐HVDC control systems, namely, that uncertain and uncoordinated control strategies switching would lead to subsequent commutation failure. Then, since power reflects variations in electrical quantities such as voltage and current, the analysis is conducted from a transmitted‐power ...

Consideration of Active Power in the SVC Control System for Flicker Mitigation in Wind Farms

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study integrates active power alongside reactive power inside the control system of static VAr compensator for flicker mitigation. The concurrent forecasting of active power and reactive power is done for 10 ms ahead through adaptive filter techniques, with real‐time updates of the autoregressive moving average model coefficients.
