Node Centrality Evaluation Based on Complex Network Theory: A Real Case Study for an Integrated Power Distribution and ICT System

Nowadays, power distribution systems and Information and Communication Technology (ICT) systems are interdependent onto each other, creating smart grids. The resilience of these integrated systems is crucial to ensure reliable performance against possible disasters and failures. To evaluate the most important components of the power grid and ICT system, complex network theory is one of the methods for modeling interdependent systems. This paper focuses on different centrality analyses for a real case study relevant to a power distribution network integrated with an ICT network. The simulation results demonstrate how centrality analysis can help identify which nodes of the power grid and the ICT network are critical for the resilience performance of the overall system.
