A Hybrid Ultra‐High Voltage DC Transformer With Digital Twin‐Driven Operation and Control
Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.This study introduces a digital twin‐driven hybrid ultra‐high‐voltage DC transformer (UHVDCT) that combines high‐capacity LCCs with low‐capacity MMCs at the UHV side. This innovative topology reduces MMC requirements by 32.9% while ensuring stable power flow and dynamic reactive balance through real‐time virtual‐physical synchronization.

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.The valve‐side single‐phase‐to‐ground (SPG) fault represents one of the most critical issues affecting the safe operation of hybrid cascade HVDC systems. This paper studies the mechanism of subsequent commutation failure caused by SPG faults on the MMC valve side in hybrid cascade HVDC systems and proposes a suppression measure.

Robustness of integrated gate commutated thyristor in switching self-clamping mode
Acta Physica Sinica<sec>As a thyristor-like device, integrated gate commutated thyristor (IGCT) is more applicable to the high-voltage and high-power fields due to the lower on-state voltage drop, and a combination of transparent anode and hard drive enables IGCT to turn off faster and more reliably.
