A Multi-Terminal HVdc Grid Topology Proposal for Offshore Wind Farms
Applied Sciences, 2020 Although various topologies of multi-terminal high voltage direct current (MT-HVdc) transmission systems are available in the literature, most of them are prone to loss of flexibility, reliability, stability, and redundancy in the events of grid ...

Configurations and earthing of HVDC grids [PDF]
2013 IEEE Power & Energy Society General Meeting, 2013 HVDC grids are considered to be essential building blocks for the future upgrade of the existing AC power system and as a means to transport the expected massive amounts of renewable energy from remote sources to the load centers. HVDC systems exist for over 50 years, yet meshed DC grids do not exist so far.

A MISO FAULT DETECTION FOR HVDC GRIDS
IET Conference Proceedings, 2021 Research on fault detection for high-voltage direct current (HVDC) grids has had a focus on single-ended DC fault detection using information from only the local line end. This paper proposes the use of additional information from neighbouring lines around the same busbar in a multiple-input single-output (MISO) fault detection.
