DC technologies will be essential building blocks for future DC distribution networks. As in
any DC system, these networks will face crucial threats imposed by short-circuit DC faults …

A high-voltage direct-current (HVDC) grid protection strategy to suppress dc fault currents
and prevent overcurrent in the arms of modular multilevel converters (MMCs) is proposed in …

An analysis of control structures for modular multilevel converters (MMCs) used in high-
voltage direct current (HVDC) applications is addressed. In particular, this paper focuses on …

The inclusion of a large number of controllable semiconductor devices in conventional
hybrid dc circuit breakers (HCBs) may significantly increase the cost of an HVdc grid …

The penetration of renewable energy resources is changing the way the power system is
understood and operated. With an increasing number of power electronics devices …

For the modular multilevel converter (MMC) based dc grid, dc fault current suppression is a
key issue. The existing fault current limiting methods by controlling half-bridge MMCs will …

Although the control of modular multi-level converters (MMCs) in high-voltage direct-current
(HVDC) networks has become a mature subject these days, the potential for adverse …

This paper suggests a methodology for the identification, classification, and evaluation of
various types of interactions that may occur in an HVDC link based on modular multi-level …

A protection scheme for DC faults has been designed for a multi-terminal HVDC network
used to transfer energy from three large offshore wind farms to shore. The system uses open …

Large offshore wind farms located far from shore, as are being planned or built in the North
Sea, will require high‐voltage DC (HVDC) transmission to shore, and multi‐terminal HVDC …
