Comparison of DC linear and non-linear models for multi-terminal VSC HVDC networks

The Journal of Engineering, 2019
The analysis and control design of multi-terminal VSC-HVDC systems requires a linearised model of these inherently non-linear systems. This paper develops such a model, from converter to multi-terminal system, discusses the key concepts and shows its use

Feasibility of applying inductive filtering technology to the HVDC transmission system

The Journal of Engineering, 2018
This study explores the feasibility of applying inductive filtering technology to high-voltage direct-current (HVDC) transmission system since only filtering in the net side may lead to a lot of harmonics in the converter transformer. Basic principles of

High Penetration of Power Electronic Interfaced Power Sources and the Potential Contribution of Grid Forming Converters [PDF]

, 2020
The traditional electrical power system and electricity markets have been designed to work with SGs, and so these have traditionally provided various 'inherent' capabilities to the system critical to ensure the stable operation of the power systems ...

Small signal analysis of DC voltage control based on a virtual resistance of DC/DC converter integrated in a multiterminal DC grid

IET Generation, Transmission & Distribution
The future multi‐terminal direct‐current (MTDC) grid will require the interconnection of point‐to‐point high‐voltage (HV) DC links with different specifications such as DC voltage level, system grounding configuration and HVDC technology.

Research and experiment of a current-limiting HVDC circuit breaker

The Journal of Engineering, 2019
Existing mechanical HVDC circuit breakers (CB) are capable of interrupting HVDC currents within several tens of milliseconds, but this is too slow to satisfy the requirements of a reliable HVDC grid.
