Voltage instability identification with modified L-index using synchrophasor data

<p>In the prevailing open-access environment, one of limitations for power exchanges has been voltage stability. The study stability necessitates a complete network representation. In this paper, advantage dynamic behavior generators is considered by incorporating models generators. It shown resulted in more accurate results compared to conventional PV buses or ideal source that are used most studies. Moreover, traditional L-index augmented real-time and synchronized phasor data collected from optimally located measurement units (PMU) wide-area system (WAMS) estimate margins. Simulation studies carried out on IEEE 9-bus 14-bus systems under various conditions. demonstrated inclusion synchrophasor WAMS significantly improves precision with which analysis obtained.</p>
