项目摘要

Power grids are a critical infrastructure upon which society relies for effective operation of many other pursuits, including commerce, healthcare, transportation, etc. The list is quite long, as electricity use pervades almost every aspect of human activity. Thus, methods for improving the resilience and security of the energy infrastructure are of deep interest to society and have substantial potential impact on its proper functioning across a very broad front. The past decade has seen an increasing interest in the application of tools developed in the interdisciplinary field of complex network analysis to improve our understanding of power system behavior. Indeed, a power grid can be naturally described as a graph where nodes represent, e.g., transformers, substations or generators, and edges represent electrical connections. Methods of complex network analysis have provided new insights into the fundamental and intrinsic characteristics of power system vulnerability and the effectiveness of associated risk mitigation strategies. However, knowledge on the role of local network structures in functionality of power systems yet remains limited. The project develops a new methodology to enhance our understanding on a functional role of various local network features in unveiling hidden mechanisms behind vulnerability of real power systems and their dynamic response to malfunctions. This project contemplates a new approach to analysis of the local topological properties of power grids via network motifs, which are smaller recurrent patterns occurring in network structure. This methodology provides a basis for understanding linkages between higher-order network topologies and functionality of power grids. The proposed formulation presents a broad platform for the development both of new analytical methods for characterizing power system stability, vulnerability and resilience, and of algorithms for detecting faults, attacks and other anomalies in power grids. Furthermore, the project provides opportunities for strengthening our understanding of the role of motifs more generally in the study of network behavior that may be applied more broadly in a variety of cyber-physical settings.

电网是社会赖以有效运行许多其他活动的重要基础设施，包括商业、医疗保健、交通等。这个清单很长，因为电力使用几乎遍及人类活动的各个方面。因此，提高能源基础设施的弹性和安全性的方法引起了社会的浓厚兴趣，并对其在广泛领域的正常运作产生了巨大的潜在影响。在过去的十年中，人们对复杂网络分析跨学科领域开发的工具的应用越来越感兴趣，以提高我们对电力系统行为的理解。事实上，电网可以自然地描述为一个图，其中节点代表变压器、变电站或发电机，边代表电气连接。复杂网络分析方法为电力系统脆弱性的基本和内在特征以及相关风险缓解策略的有效性提供了新的见解。然而，关于本地网络结构在电力系统功能中的作用的知识仍然有限。该项目开发了一种新的方法，以增强我们对各种本地网络特征的功能作用的理解，揭示真实电力系统脆弱性背后的隐藏机制及其对故障的动态响应。该项目设想了一种通过网络图案（网络结构中出现的较小的循环模式）分析电网局部拓扑特性的新方法。该方法为理解高阶网络拓扑和电网功能之间的联系提供了基础。所提出的公式为开发表征电力系统稳定性、脆弱性和弹性的新分析方法以及检测电网故障、攻击和其他异常的算法提供了广阔的平台。此外，该项目为加强我们对网络行为研究中主题作用的更广泛理解提供了机会，这些网络行为可以更广泛地应用于各种网络物理环境。
