Abstract :
This letter presents an uncertainty quantification method for phasor measurement units (PMUs) in voltage stability assessment. The effect of local phasor measurement uncertainty on the Thevenin equivalent impedance used for voltage stability analysis is quantified analytically. The results can be used to specify the requirements for PMU uncertainty in voltage stability assessment.
