Stability and interaction analysis in islanded power systems including VSC-HVDC and LCC-HVDC power converters [PDF]

open access: yes, 2018
Islanded power systems are often connected to larger mainland power systems using HVDC cables. These interconnections are used to import power at lower cost compared to local generation and improve the security of supply.

Exploiting Redundant Energy of MMC–HVDC to Enhance Frequency Response of Low Inertia AC Grid

open access: yesIEEE Access, 2019
This paper presents a grid frequency responsive inertial control for the modular multilevel converter-high voltage DC (MMC-HVDC) using the MMC design attribute, i.e. submodule redundancy for high reliability.
