Abstract
This paper presents a strategy for regulation of power factor in an embedded high-voltage direct current (HVDC) system based on modular multilevel converter (MMC) technology. Field reported in existing literature are taken as a reference for qualitative assessment of the performance of the proposed strategy. The implication of adding such a type of control mode in an MMC-HVDC system is determined through software experiments performed in DIgSILENT PowerFactory. The results reveal that the power factor can be effectively controlled by an MMC-HVDC link within its power rating limits, even in the case of changes of the active power reference.
