摘要

Abstract

This paper systematically investigates the multi-degree-of-freedom (multi-DoF) control framework of high voltage direct current (HVDC) converters based on their topological characteristics and control requirements. First

this study reveals that its topology determines the control degrees of freedom (CDoF) of a converter. Specifically

a line-commutated converter (LCC) possesses only one CDoF

a voltage source converter (VSC) has two

and a modular multilevel converter (MMC) can theoretically achieve up to eight. However

only six CDoF are practically necessary for MMC. Despite this

existing MMC control strategies utilize only four CDoF

limiting control flexibility. To overcome this issue

this paper proposes a six-degree-of-freedom (6 DoF) control framework for MMC

which enables asymmetric and precise regulation of DC voltage and SM capacitor voltage compared to the existing MMC control. Based on this framework

corresponding control strategies are designed for MMCs in HVDC systems with different control objectives. Finally

a two-terminal MMC-HVDC system is built on the PSCAD/EMTDC to verify the effectiveness of the proposed 6 DoF control.
