Abstract :
In order to prevent voltage collapse, lots of voltage stability assessments are proposed to search weak buses. However, these assessments are either only related to network topology or time-consumed. Therefore, voltage stability extended voltage sensitivity factor (EVSF), an improved voltage stability assessment considering voltage regulation of generator and HVDC, is given and derived in this paper. And a case is illustrated and analyzed. Comparing with VSF indicator, EVSF is more considerate and sensitive to discover weak buses with multi-infeed HVDC. It´s proved that EVSF is an effectiveness assessment for power system voltage stability analysis.
