Power grids are cyber-physical systems and can be modelled as network systems where
individual units (generators, busbars and loads) are interconnected through physical and …

INTRODUCTION Cascading failures in power grids are inherently network processes, in
which an initially small perturbation leads to a sequence of failures that spread through the …

The US electrical grid, the largest and most complex man-made system in the world, is
highly vulnerable to three types of external threats: 1) natural disasters, 2) intentional …

We consider line outages in the transmission network of the power grid, and specifically
those caused by natural disasters or large-scale physical attacks. In such networks, an …

This paper focuses on joint cyber and physical attacks on power grids and presents methods
to retrieve the grid state information following such an attack. We consider a model where an …

Motivated by the recent cyber attack on the Ukrainian power grid, we study cyber attacks on
power grids that affect both the physical infrastructure and the data at the control center …

This paper focuses on cascading line failures in the transmission system of the power grid.
Recent large-scale power outages demonstrated the limitations of percolation-and epidemic …

Sudden failure of a single transmission element in a power grid can induce a domino effect
of cascading failures, which can lead to the isolation of a large number of consumers or …

Networks interact with one another in a variety of ways. Even though increased connectivity
between networks would tend to make the system more robust, if dependencies exist …

ABSTRACT A failure of one or even a few components would have a limited impact on the
network-level performance if the negative consequences are compensated for by …
