Voltage/power stability study upon power system with multiple-infeed configuration of HVDC links using quasi-static modal analysis approach

Abstract

Quasi-Static Modal Analysis methodology is extended to a fictional system with multiple-infeed configuration of 5 HVDC links for voltage/power stability analysis study. Weak elements or area in the electrical system can be identified by using Q-V modal analysis with eigenvalues, participation factors and V-Q sensitivities. Maximum Power Curves, indicating stability margin for HVDC links, are used to analyze HVDC links that are integrated in AC system, for power stability analysis purpose.
