Voltage Stability Bifurcation Analysis for AC/DC Systems with VSC-HVDC

Abstract and Applied Analysis, 2013
A voltage stability bifurcation analysis approach for modeling AC/DC systems with VSC-HVDC is presented. The steady power model and control modes of VSC-HVDC are briefly presented firstly.

Grid Synchronisation of VSC-HVDC System

, 2015
This thesis investigates issues affecting grid synchronisation of VSC-HVDC systems with particular regard to, but not limited to, offshore wind power generation during the complex but potentially serious behaviours following solar storms. An averaged value model (AVM) for the contemporary modular multilevel converter (MMC) based VSC-HVDC system is ...

Analysis of multi-infeed receiving AC system with incompletely segmented VSC-HVDC

Global Energy Interconnection
When multiple LCC-HVDC transmission lines are densely fed into a receiving AC system, voltage dips can easily propagate in the power system, resulting in multiple LCC commutation failures simultaneously.
