Abstract :
The study presents a new method for monitoring the voltage stability condition of a bus using measurements of the bus variables. For this purpose, bus real power, bus reactive power and bus voltage of a target/selected bus have to be measured (sampled) for two consecutive time frames. These measured values are used to monitor the voltage stability condition of a bus using the mathematical basis developed in this study. The validity and applicability of the proposed method has been established through simulation on IEEE 30 and IEEE 118 bus system.
