Abstract
In recent years, protecting large-scale complex networks, such as electric power grids and their monitoring systems, has become a critical part of cutting-edge research. Adversaries often attempt to intercept and hack these systems by interfering with intermediate nodes or preventing controllers and physical systems from receiving actuator signals and industrial sensor measurements. The present work concentrates primarily on the structural controllability of such systems, as this topic has recently received significant interest through the equivalent problem of the power dominating set within the field of electrical power and network control. Nonetheless, it is well established that these problems are NP-hard with low approximation. Developing strategies that can restore a network's performance is critical given their importance for a wide range of networks, particularly power networks. Thus, this paper focuses on regaining the structural controllability for Erdos-Renyi random directed networks following attacks on edges. Furthermore, these strategies will be evaluated using Matlab simulations to examine their applicability in real-world contexts.
