“…The above design methods regard all the outside nodes of the largest connected component of each network as being in a failure state on the basis of the percolation theory [30]- [35]. A heuristic method has minimized the required number of interconnections for preventing the cascading failures invoked from single node failures [36]. The method guaranteed the connectivity of each distribution node with one of the generation nodes in the power grid.…”

“…Here, communication routes are selected to minimize the impact of an inter-network cascading failure process between communication network and power network. The work [25] has formulated an integer linear program to find the desired number of interconnections between power network and optical communication network for resiliency against cascading failures initiated from a single node-failure. In [26], a communication-dependent cascading failure model has been proposed to capture the failure behaviors in a power network, where communication delay in delivering control commands plays a crucial role on the effectiveness of control strategies.…”

Smart grid has a power network with an interdependent communication network. In such a system, a node failure can lead to another failure in its dependent node in the other network. These internetwork failures can occur recursively in a cascading process, resulting in a complete system collapse. Such cascading failure process can be interrupted by providing backup power to communication nodes, so that they can continue operation when the power nodes they depend on have failed. It is costly to install a backup power unit at each communication node. We have used the two-stage percolation theory to determine the system robustness as a function of backup power deployment density and backup power unit capacity. Then, we propose a novel scheme to determine the optimal backup power deployment density and unit capacity, which can minimize the backup power deployment cost without compromising a desired system robustness. Through extensive simulations, we have found that when the probability of initial node failure is below its critical value, the deployment cost may decrease linearly with a smaller network size and may increase exponentially with a higher robustness requirement.INDEX TERMS Smart grid, interdependent network, backup power, cascading failure, cyber-physical system.PENG-YONG KONG (Senior Member, IEEE) received the B.Eng. degree (first class honours) in electrical and electronic engineering from Universiti Sains Malaysia and the Ph.D. degree in electrical and computer engineering from the National University of Singapore.

“…The fault tolerance of power grids is an efficient measure to assess the reliabilities of the corresponding power systems. Habib et al [1] considered the problem on the power grid-optical network interconnection to avoid or reduce cascading failures in power systems. Chai et al [2] summarized the health monitoring of power grids based on the fiber optic sensing technology.…”

As power grids and optical interconnection networks are interdependent, the reliabilities of the optical networks are critical issues in power systems. The optical networks hold prominent performance including wide bandwidth, low loss, strong anti-interference capability, high fidelity, and reliable performance. They are regarded as promising alternatives to electrical networks for parallel processing. This paper is aimed at taking the first step in understanding the communication efficiencies of optical networks. For that purpose, on optical networks, we propose a series of novel notions including communication pattern, r -communication graph, reduced diameter, enhanced connectivity, r -diameter, and r -connectivity. Using these notions, we determine that the r -diameter and r -connectivity of the optical n -dimensional hypercube network are n / r and n 1 + n 2 + ⋯ + n r , respectively. Since the parameter r is variable, we can adjust different values of r on the basis of the wavelength resources and load of the optical networks, achieving enhanced communication efficiencies of these networks. Compared with the electric n -dimensional hypercube network, the proposed communication pattern on the optical hypercube network not only reduces the maximum communication delay of the conventional electrical hypercube significantly but also improves its fault tolerance remarkably.
