摘要：The immunity of a power network against unplanned or designated vulnerable attacks isgaining importance in recent years. The capability of the network to resist fragmentation,mitigate and overcome stresses and failures are characterized by the resiliency of the network.In this paper, an attempt has been made to employ the concepts of complex network theoryintegrated with statistical methods in order to determine the criticality of damage to the nodesand edges of topographical model of an electrical power system encountering a vulnerable attackon that power system. Betweenness centrality of an electrical power network being one of theprime parameters of assessment for vulnerability of that network, computations have beenconducted in a test network in order to obtain the moments of degree distribution of thatnetwork. This investigation facilitates the quantification of critical fraction of damaged nodes aswell as the percolation threshold of the power network. This study highlights the characterizationof resiliency of a typical electrical power network following a routine electrical failure, outage ordesignated attack on that electrical power system. The benefit of installing DistributedGeneration (DG) at the critical nodes (buses) of the same electrical power network has alsobeen observed.
