Experimental study on fault ride-through capability of VSC-based HVDC transmission system [PDF]
For voltage-source-converter based high-voltage-direct-current (VSC-HVDC) transmission systems, fault ride-through (FRT) capability is a very important grid requirement in order to enhance its operational availability under an alternating current (AC ...

A new multi-port interline DC power flow controller for multi-terminal HVDC grids
In Multi-Terminal High-Voltage Direct Current (MT-HVDC) Grids, the current of Direct Current (DC) lines are naturally dispersed depending on the DC line resistance and the difference in the voltage at various DC terminals.

HVDC (High Voltage Direct Current) Transmission System: A Review Paper [PDF]
Back in the early days of electricity supply, AC (alternating current) was adopted for power transmission because it could be stepped up or down as needed by transformers and because it could be interrupted more easily than DC (direct current). High-voltage AC grids evolved as an efficient way to connect existing islands of distribution grids and large
