Fast Harmonic compensation in hybrid HVDC offshore system
Hybrid HVDC systems have been proposed as an alternative for nominal VSC-Based HVDC for offshore applications. Hybrid HVDC systems consist of an offshore power station composed of the connection of high-power diode rectifiers in series with a fractional power VSC-HVDC.

A Hybrid Ultra‐High Voltage DC Transformer With Digital Twin‐Driven Operation and Control
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.

Shielding of Unconventional High Surge Impedance Loading Transmission Lines
This paper focuses on determining the optimal location and number of shield wires for a novel‐designed unconventional high surge impedance loading line. This line has a much lower surge impedance than conventional lines, raising key questions on the location of shield wires to meet an acceptable shielding failure rate (SFFOR).

A Hybrid Reliability Evaluation Method for Meshed VSC-HVDC Grids
High-voltage direct current (HVDC) grids are emerging, and their reliability has been an increasing concern for the utilities. HVDC grids are different from typical two-terminal HVDC transmission systems due to the loops in their topology, which makes it

Hybrid HVDC circuit breaker with self‐powered gate drives [PDF]
The ever increasing electric power demand and the advent of renewable energy sources have revived the interest in high‐voltage direct current (HVDC) multi‐terminal networks. However, the absence of a suitable circuit breaker (CB) or fault tolerant voltage source converter station topologies with the required characteristics (such as operating speed ...

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