Query: Fast-timescale Line Failure Control in Power Systems   Transmission line failures in power systems propagate and cascade
non-locally. In this work, we propose a fast-timescale distributed control
strategy that offers strong guarantees in both the mitigation and localization
of line failures. Specifically, we leverage the properties of network
bridge-block decomposition and a frequency regulation method called the unified
control. If the balancing areas over which the unified control operates
coincide with the bridge-blocks of the network, the proposed strategy drives
the post-contingency system to a steady state where the impact of initial line
outages is localized within the areas where they occurred whenever possible,
stopping the cascading process. When the initial line outages cannot be
localized, the proposed control strategy provides a configurable design that
progressively involves and coordinates more balancing areas. We compare the
proposed control strategy with the classical Automatic Generation Control (AGC)
on the IEEE 118-bus and 2736-bus test networks. Simulation results show that
our strategy greatly improves overall reliability in terms of the $N-k$
security standard, and localizes the impact of initial failures in majority of
the simulated contingencies. Moreover, the proposed framework incurs
significantly less load loss, if any, compared to AGC, in all our case studies.
