Abstract

Restoration of modern interdependent Information and Communication Technology (ICT) and power networks relies on preplanned and reactive strategies to consider simultaneous communication and power system recovery. This paper addresses the problem of finding and energizing a proper communication network connecting the distributed power grid assets in the restoration process, assuming a probability of infeasibility of recovering each communication node. The proper network has the minimum size, meets the communication requirements of power system recovery, and guarantees robustness against ICT nodes not being recoverable during restoration. The problem is formulated as a multi-objective optimization problem and solved using the genetic algorithm to find the optimal subgraph that ensures enough node-disjoint paths between the communicating power grid assets. Simulation results for the restoration strategy of the communication network associated with a power network are provided and discussed. The results show that networks’ ability to mitigate the adverse consequences of node failures can be significantly improved by incorporating just a few additional nodes and links while keeping the ICT network compact and feasible for restoration.

为有效恢复电力系统建立最佳通信网络

现代相互依存的信息与通信技术（ICT）和电力网络的恢复依赖于预先计划和被动策略，以考虑通信和电力系统的同步恢复。本文探讨的问题是，假设每个通信节点都有可能无法恢复，如何在恢复过程中找到并启动连接分布式电网资产的适当通信网络。合适的网络具有最小的规模，能满足电力系统恢复的通信要求，并保证在恢复过程中信息和通信技术节点无法恢复时的鲁棒性。该问题被表述为一个多目标优化问题，并使用遗传算法求解，以找到最佳子图，确保通信电网资产之间有足够的节点间路径。提供并讨论了与电网相关的通信网络恢复策略的仿真结果。结果表明，只需增加几个节点和链路，就能显著提高网络减轻节点故障不良后果的能力，同时保持信息和通信技术网络的紧凑性和恢复的可行性。
