摘要

Abstract

This paper proposes an enhanced grid-forming (GFM) control scheme for modular multilevel converter-based high-voltage direct current (MMC-HVDC) systems interfacing offshore wind farms. The proposed strategy adopts an improved DC voltage synchronization approach

which not only provides instantaneous active and reactive power support

but also achieves enhanced DC-link voltage regulation. To validate its control performance

PSCAD/EMTDC simulations are conducted using the actual parameters of the Borwin6 MMC-HVDC project. Simulation results demonstrate the scheme's effectiveness in delivering instantaneous grid support and maintaining system stability under various challenging conditions

including phase angle jumps

frequency variations

voltage dips

short-circuit ratio (SCR) changes and AC grid faults.
