ABSTRACT:
A method of identifying voltage instability in a power system via identification of a weakest line and bus that contribute to the collapse of the system is provided. The method includes periodically calculating an extended line stability index for the transmission lines monitored in the power system; and using the extended line stability index to determine the distance of an operation state in the power system from a collapse point of the system caused by voltage instability.
