Line Failure Localization of Power Networks Part II: Cut Set Outages

Transmission line failure in power systems prop-agate non-locally, making the control of resulting outages extremely difficult. In Part II this paper, we continue study localizability transmission networks and characterize impact cut set outages. We establish a Simple Path Criterion, showing that propagation pattern due to bridge outages, special case failures, are fully determined by positions network buses participate load balancing. then extend our results general contrast non-cut discussed I whose subsequent failures contained within original blocks, typically whole network, affecting flows on all remaining lines. corroborate analytical both parts using IEEE 118-bus test system, which patterns exhibit clear block-diagonal structure predicted theory, even when full AC flow equations.
