The modular multilevel converter (MMC) is currently the preferred converter topology for
HVDC point-to-point links and the likely choice for future meshed HVDC grids. For breaker …

High-voltage direct current (HVDC) grids will require the development of dc protections that
provide fast fault isolation and minimize the disturbance caused to the existing ac power …

DC faults can cause serious problems such as power outage or even damaging the
electrical equipment. The aim of this paper is to compare four DC fault clearance schemes in …

The feasibility of future multiterminal dc (MTDC) systems depends largely on the capability to
withstand dc-side faults. Simulation models of MTDC systems play a very important role in …

Without additional circuitry, the half-bridge modular multilevel converter (HB-MMC) is
endangered under dc-side faults. Typically, a bypass thyristor is augmented to each HB cell …

HVDC DC grids composed of half-bridge modular multi-level converters (HB MMC) can be
protected against DC faults using DC circuit breakers (DCCBs). However, the rapid increase …

The modular multilevel converter (MMC) with half-bridge submodules (SMs) is the most
promising technology for high-voltage direct current (HVDC) grids, but it lacks dc fault …

This paper studies the dc fault development stages and analyzes the fault dynamics in a
point-to-point multilevel modular converters (MMC)-based dc connection. First, the effect of …

High voltage direct current (HVDC) grids may be protected from dc faults through the
application of HVDC circuit breakers. Recent advances in dc circuit breaker technologies …
