Optimal PMU Placement Considering with HVDC Links and Their Voltage Stability Requirements [PDF]
AUT Journal of Electrical Engineering, 2019 In wide area measurement systems, PMUs are the main component measuring real time synchronized data from different buses. Installation of PMUs at all buses is a primary way to provide full observability of the power network.

Unified reference controller for flexible primary control and inertia sharing in multi-terminal voltage source converter-HVDC grids [PDF]
, 2016 Multi-terminal dc (MTDC) grids are expected to be built and experience rapid expansion in the near future as they have emerged as a competitive solution for transmitting offshore wind generation and overlaying their ac counterpart. The concept of inertia

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).
