Abstract

The problem of voltage instability has been increasing day by day because of the increased demand of power. It is important to analyze the power system behavior with respect to voltage stability. This paper shows the performance of the stability indices. The two indices whose analysis are performed in the paper are line stability index and fast voltage stability index. The indices are tested on IEEE 14 bus standard test system. The simulation of the IEEE 14 bus system is implemented using PSAT toolbox. With the help of the above mentioned indices the most critical lines and the weakest buses can be identified. Lines having index value equal to one or close to one are considered as the most critical lines.
