The Power Grid, the Internet, and the transport network are examples of complex systems. In contrast to simple systems, complex systems show emergent behaviors caused by the unpredictable yet rare non-linear interactions of their numerous social, physical and cyber components. Complex systems can experience disruptive and massive failures, such as the blackout of the Northeastern states or the halt on maritime and rail operations in the UK and Australia. Our research aims at 1) determining theoretical characteristics of robust complex networks and 2) improving the robustness of the power grid by implementing mitigation strategies against cascading failures, using a network representation of the power grid.
