QUANTITATIVE FEEDBACK THEORY DESIGN OF LINE CURRENT COMMUTATED HVDC CONTROL SYSTEMS [PDF]

open access: yes, 2020
: Line Current Commutated (LCC) HVDC systems consists of uncertain plants. These uncertainties are result of changes/disturbances in the ac networks or in the LCC HVDC system itself.

Machine learning-guided optimal power flow for weak hybrid AC-DC grids [PDF]

open access: yes
This paper presents a novel machine learning-guided approach for optimal power flow in weak hybrid AC-DC grids. The methodology addresses two key challenges: voltage stability in weak grids and the integration of LCC-HVDC systems.

Compound Line-Commutated Converter with Commutation Voltage Compensation and Power Consumption Capability for Commutation Failure Suppression

open access: yesCSEE Journal of Power and Energy Systems
To mitigate commutation failures (CFs) of a line-commutated converter based-high voltage direct current transmission system (LCC-HVDC), an evolved thyristor based full bridge sub-module (ET-FBSM) and a compound LCC (CLCC) topology are proposed with the ...
