N2 - Communication networks are providing enhanced control and management strategies to the smart grids via a set of control center units. However, the interdependency between communication networks and power grids increases the risk of large-scale joint cascading failures. In this paper, the impact of the near-optimal allocation of control centers on the vulnerability of power-communication networks against joint cascading failure attacks is studied. A joint attack strategy is proposed based on the most influential nodes in power grids and communication networks. Then, the number and locations of control centers in such interdependent system are optimized to reduce the system's vulnerability. Results reveal that the allocation of control centers can reduce system vulnerability against joint attacks, however, the damaging impact remains severe.
