Stability Enhancement for VSC-HVDC Systems by ramya sree is a document available to read on EtoBox.
This document presents a stability enhancement approach for VSC-HVDC systems connected to weak AC grids. It begins by deriving a multi-input multi-output transfer function model of the VSC system. It then uses an individual channel analysis and design approach to develop an equivalent single-input single-output feedback control model for stability analysis. The results show that a larger PLL bandwidth increases coupling between the active and reactive power control loops, resulting in instability under weak
