Abstract
A method that exploits Thevenin equivalent representation
for obtaining post-contingency steady-state nodal
voltages is integrated with a method of detecting post-contingency
aperiodic small-signal instability. The task of integrating stability
assessment with contingency assessment is challenged by the
cases of unstable post-contingency conditions. For unstable postcontingency
conditions there exists no credible steady-state which
can be used for basis of a stability assessment. This paper
demonstrates how Thevenin Equivalent methods can be applied
in algebraic representation of such bifurcation points which may
be used in assessment of post-contingency aperiodic small-signal
stability. The assessment method is introduced with a numeric
example.
