项目摘要

The electric power industry is undergoing profound transformations due to the advances in information technology, stronger interoperability between the physical and cyber layers of the power grid, and deregulations in the energy market. Driven by such transformations, power grids are rapidly growing in scale, complexity, and interconnectivity, evolving towards distributed networks of interconnected platforms. Such highly distributed structures expose the power grid to critical security vulnerabilities, such that malicious attackers bent on subverting grid operations can severely disrupt energy generation, transmission, and distribution. The overarching goal of this proposal is to develop a decision-theoretic approach that includes security as an integral part of design mechanisms in power grids, rendering inherently secure operations.The key motivation underpinning this research is that current monitoring, protection, and control functions in power grid are designed without regard for inherent security, and security vulnerabilities are addressed as they are discovered. Therefore, while being effective against naturally occurring faults and attacks with known structures, they lack the versatility to counter highly structured and unknown cyber attacks. This research produces a decision-theoretic framework that integrates security assurance as a constraint in designing and optimizing monitoring and control modules while adopting realistic models for adversaries, and incorporating generation, transmission, and operational constraints. This framework facilitates analyzing the tradeoffs among three key measures involved in designing any operation in monitoring and control modules, namely: (i) security guarantees, (ii) quality the operation (through assigning appropriate performance measures that match the goals of the operations), and (iii) amenability to real-time and scalable implementation. These analytical results guide transformational approaches to secure monitoring and protection in future energy grids. These approaches are in contrast to the existing designs in which operations are optimized for attack-free settings, and are augmented by additional modules to enhance their resiliency against known classes of cyber attacks. The methods used to address these problems include mathematical statistics, statistical signal processing, optimization theory, and power engineering.The educational component of this research is composed of several parts aimed at students ranging from the high school to graduate level, and from several demographics. In collaboration with the Engineering Ambassadors program at Rensselaer, this research program develops interactive presentations for high-school students about modern notions of cyber security, which involve undergraduate students as assistants in delivering these presentations, who will be also involved in research. Other educational components include designing curricular materials for graduate courses on the applications of modern data science in power grids.

随着信息技术的进步、电网物理层和网络层之间更强的互操作性以及能源市场的放松管制，电力行业正在经历深刻的变革。在这种变革的推动下，电网的规模、复杂性和互联性正在迅速增长，并朝着互联平台的分布式网络发展。这种高度分布式的结构使电网暴露于关键的安全漏洞，使得恶意攻击者执意破坏电网运营，可能严重破坏能源的生产、传输和分配。该提案的总体目标是开发一种决策理论方法，其中包括安全性作为电网设计机制的一个组成部分，呈现固有的安全Operations.The关键动机支撑这项研究是，目前的监测，保护和控制功能在电网的设计不考虑固有的安全性，安全漏洞，因为他们被发现，并解决。因此，虽然它们可以有效地对抗自然发生的故障和具有已知结构的攻击，但它们缺乏对抗高度结构化和未知网络攻击的通用性。本研究产生了一个决策理论框架，集成了安全保证作为一个约束，在设计和优化监测和控制模块，同时采用现实模型的对手，并将发电，传输和操作的限制。该框架有助于分析在设计监测和控制模块中的任何操作时所涉及的三个关键措施之间的权衡，即：（i）安全保证，（ii）操作质量（通过分配与操作目标相匹配的适当性能措施），以及（iii）对实时和可扩展实施的顺从性。这些分析结果指导了未来能源电网安全监测和保护的转型方法。这些方法与现有的设计相反，在现有的设计中，操作针对无攻击设置进行了优化，并且通过额外的模块进行了增强，以增强其对已知类型的网络攻击的弹性。用于解决这些问题的方法包括数理统计，统计信号处理，最优化理论和电力engineering.本研究的教育组成部分是由几个部分，针对从高中到研究生水平的学生，并从几个人口统计。与伦斯勒的工程大使计划合作，该研究计划为高中生开发了关于网络安全现代概念的交互式演示文稿，其中涉及本科生作为助手提供这些演示文稿，他们也将参与研究。其他教育内容包括为研究生课程设计现代数据科学在电网中的应用的课程材料。
