Maximum power systems loadability to detect voltage collapse

Abstract

This paper discusses voltage stability analysis of power systems using two static voltage stability analyses: voltage sensitivity, modal analysis including participation factor. These methods determine how far the power system is from its break point providing relative measure of voltage instability proximately. Results show all method indices share voltage stability margins having a precise voltage collapse point when a power system is subjected to sudden load increase. The application has been demonstrated on the IEEE 14-bus System.
