Abstract

Recent advances in the field of information and communication technology (ICT) have led power system's operators to seek assistance from communication network for the continuity of normal operation of this critical infrastructure. However, connecting the communication network to the power system facilitated its operation, but nevertheless caused issues that were not previously apparent. One of these issues is the infection of damage from one infrastructure to another. Sometimes this damage goes so far as not to leave any connection between the infrastructures. In this paper, percolation theory has been used to find the threshold of disconnection of interconnected infrastructures. Two critical infrastructures are modeled as an interconnected network and then it is decomposed into three distinct graphs. By using the adjacency matrices of these three graphs, without actually simulating of any percolation process, the phase change diagram of interconnected network is drawn. Also, the most vital connections between the two infrastructures and the most vulnerable nodes of each infrastructure are identified from the consequences of the present model analysis. These results can be used in code regulation for connection of communication network to the power system.
