Market Integration of HVDC Lines: Internalizing HVDC Losses in Market Clearing [PDF]
IEEE Transactions on Power Systems, 2020 Moving towards regional Supergrids, an increasing number of interconnections are formed by High Voltage Direct Current (HVDC) lines. Currently, in most regions, HVDC losses are not considered in market operations, resulting in additional costs for Transmission System Operators (TSOs).

A novel HVDC circuit breaker for HVDC application [PDF]
International Journal of Electrical Power & Energy Systems, 2019 Hybrid high voltage direct current circuit breakers (DCCBs) are capable of interrupting fault current within a few milliseconds, but this technology has high capital cost, especially in a meshed HVDC grid. To increase the economic competitiveness of hybrid DCCBs, this paper proposes a capacitor commutated dc circuit breaker (CCCB).
