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.
