Abstract
This article studies the influence of PMU’s accuracy
in voltage stability assessment, considering the specific case
of Th
́
evenin equivalent based methods that include wide-area
information in its calculations. The objective was achieved by
producing a set of synthesized PMU measurements from a time
domain simulation and using the Monte Carlo method to reflect
the accuracy for the PMUs. This is given by the maximum value
for the Total Vector Error defined in the IEEE standard C37.118.
Those measurements allowed to estimate the distribution pa-
rameters (mean and standard deviation) of the studied voltage
stability indices and grid transformation coefficients which have
applications in voltage stability assessment. The obtained distri-
butions have a direct impact in the number of samples needed
for estimating system parameters and compromise between time-
scale and uncertainty in those estimations is shown.
