摘要

本文以支持广域态势感知的通信为重点,讨论了智能电网对通信可靠性的要求。广域态势感知的实现依赖于传输变电所网络和广域光网络。本文对加州电网的一个样本通信网络的可靠性进行了研究,发现其可靠性达不到提出的要求。为了克服这一问题,我们考虑在满足可靠性要求的同时使网络成本最小化的网络设计问题。因此,我们提出了两种贪婪迭代启发式算法和一种启发式整数线性规划(H-ILP)模型,利用最小割集进行网络可靠性优化。贪婪迭代算法在成本方面优于H-ILP方法,但需要更多的计算资源。这两种模型实际上是互补的,因此为优化智能电网通信网络的可靠性提供了一个框架。

On smart grid communications reliability
In this paper, we discuss the communications reliability requirements posed by the smart power grid with a focus on communications in support of wide area situational awareness. Implementation of wide area situational awareness relies on both transmission substation networks and wide area optical networks. We study the reliability of a sample communications network of the California Power Grid and find that its reliability falls short of proposed requirements. To overcome this issue, we consider the problem of designing the network to meet the reliability requirements while minimizing the network cost. Therefore, we propose two greedy iterative heuristics and a heuristic integer linear programming (H-ILP) model using minimum cut-sets for network reliability optimization. The greedy iterative algorithms outperform the H-ILP approach in terms of cost, but require a larger amount of computing resources. Both proposed models are in fact complementary and thus provide a framework to optimize the reliability of smart grid communications networks.
