Abstract

A two-stage monitoring technique for power system stability is considered. The process utilizes a technique, discussed by some of the authors elsewhere, for identifying coherent dynamic clusters within a power system and the connections between the clusters and critical swings in the power system. In the first stage transient energy injected into the power system is compared with critical energies which can drive the cluster into separation. Failing this sufficiency test, the condition is evaluated by testing the initial-states position directly with respect to the stability boundary. An effective expansion which is easily derived on the computer is used. Only one scalar value needs to be computed for each candidate. New theoretical, computational results on identifying order -N-1 equilibria are included.
