Research on Voltage Regulation Methods for Flexible On‐Load Tap‐Changing Transformers
Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.The control system determines whether the output voltage magnitude of the voltage source converter (VSC) is high, low or constant and generates the corresponding pulse signals. Each pulse is generated at the valve‐triggering instant, with its width corresponding to the commutation angle.

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.ABSTRACT When multiple grid‐forming and grid‐following converters operate within an offshore energy system (OES), dynamic interactions among them can lead to poorly damped oscillations and potential instability. This paper proposes a computationally efficient reduced‐order state‐space modelling framework for small‐signal stability and parametric ...

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 ...

VSC-HVDC for Frequency Support (a review) [PDF]
13th IET International Conference on AC and DC Power Transmission (ACDC 2017), 2017 To reduce CO2 emissions produced by electricity generation, conventional fossil fuel power plants are being decommissioned. Renewable energy sources (RES) and interconnectors are replacing these old power plants but have different operating characteristics.
