Modular multilevel converter based multi-terminal HVDC (MMC-MTDC) technology is
increasingly adopted as a promising option in the power transmission and distribution fields …

The development of a low-voltage dc distribution network has advanced the research on dc
circuit breakers. Compared with the Z-source circuit breakers, T-source circuit breakers offer …

In recent years, the demand for HVDC grids has greatly increased due to the integration of
renewable energy, especially offshore wind energy. The current flow within the DC grid is …

This paper presents a new topology for solid-state HVDC circuit breakers which does not
require MOV for fault energy absorption. Due to its simple yet robust design, it offers a …

The challenges of an HVDC breaker are to generate impulsive forces in the order of
hundreds of kilonewtons within fractions of a millisecond, to withstand the arising internal …

These thesis works mainly focus on the modeling, sizing and control of a hybrid-
modularconverter named: Extended Overlap-Alternate Arm Converter (EO-AAC). The first …

DC fault protection is one of the biggest challenge to multi-terminal direct current (MTDC)
systems, because DC current has no natural zero crossing point. To overcome this problem …

Renewable energy sources stand out as a chance for a sustainable future due to many
problems. One significant kind of renewable energy power system is solar energy storage …

Considering the importance that HVDC systems are expected to have in the future of power
networks, this paper aims to provide a wide overview of the protection against DC faults. In …

The landscape of direct current (DC) solid-state circuit breakers (SSCBs) is growing and so
too is the choice of primary components. There now exists a wide range of devices capable …
