摘要

Abstract

Modular multilevel converters (MMC) have been widely applied in high voltage direct current (HVDC) transmission systems

while complex dynamic characteristics pose challenges for stable operation under large-signal disturbance. In this paper

large-signal stability of MMC is investigated under grid voltage and power disturbances based on mixed potential function (MPF). First

an MMC simplified model based on average value model (AVM) is introduced. Then

the physical mechanism of large-signal instability phenomenon is revealed for MMC. Based on the simplified model

large-signal stability of MMC is analyzed by applying MPF. Furthermore

to diminish the conservatism of MPF

a large-signal stability criterion is defined by introducing a conservative correction factor. The influences of system parameters on large-signal stability of MMC are presented by the region of asymptotic stability (RAS). Finally

PLECS simulation case studies are carried out to verify the proposed stability criterion under grid voltage and power disturbances.
