Abstract
Reasonably large perturbations may push a power grid from its stable
synchronous state into an undesirable state. Identifying vulnerabilities in
power grids by studying power grid stability against such perturbations can aid
in preventing future blackouts. We use two stability measures $\unicode{x2014}$
stability bound, which deals with a system's asymptotic behaviour, and
survivability bound, which deals with a system's transient behaviour, to
provide information about the strength of perturbations that destabilize the
system. Using these stability measures, we have found that certain nodes in
tree-like structures have low asymptotic stability, while nodes with a high
number of connections generally have low transient stability.
