Practical calculation of SCR of LCC-HVDC considering the role of VSC-HVDC
The accurate quantification of transmission limit and grid strength of the multi-infeed LCC-HVDC (line-commutated converter technology-based high-voltage DC) and VSC-HVDC (voltage source converter technology-based high-voltage DC) systems has become one ...

Fast Harmonic compensation in hybrid HVDC offshore system
Hybrid HVDC systems have been proposed as an alternative for nominal VSC-Based HVDC for offshore applications. Hybrid HVDC systems consist of an offshore power station composed of the connection of high-power diode rectifiers in series with a fractional power VSC-HVDC.

Modeling and enhanced control of hybrid full bridge–half bridge MMCs for HVDC grid studies [PDF]
Modular multilevel converters (MMCs) are expected to play an important role in future high voltage direct current (HVDC) grids. Moreover, advanced MMC topologies may include various submodule (SM) types. In this sense, the modeling of MMCs is paramount
