Modeling the Interaction of Power Line and SCADA Networks

In this work, we discuss the robustness of a power line network and a SCADA network to interacting failures. Previous research on network robustness is mainly focused on the structural properties of a single network. However if systems consist of multiple interdependent networks, their interaction must be considered. This work considers power distribution systems which consist of a power line network and a SCADA network and evaluates the effects of the interaction between the two networks on the robustness of the system. The evaluation results suggest that the robustness increases as the inter-similarity between the two networks increases.
