TC: Small: Secure the Electrical Power Grid: Smart Grid versus Smart Attacks

不断增长的能源需求和对环境的关注大大增加了学术界、工业界和政府对发展智能电网的兴趣。安全是电力系统的关键问题之一。这项研究的目的是改进脆弱性分析方法，并开发创新的应对措施，以在复杂攻击(包括网络攻击和物理故障)下保持电网的完整性。这项研究将有助于开发健壮、安全、可靠的未来智能电网系统。不同于现有的许多工作集中于抽象的拓扑结构或基于负载的分析，该项目同时考虑网络拓扑和固有的潮流特性来理解复杂电网攻击下的系统行为。这包括单节点和多节点漏洞分析，开发新的风险感知指标，考虑时间和位置的时空攻击，以及因链路故障而增强的多方面攻击。了解电网系统在攻击场景下的行为将使我们能够制定新的防御策略。由于电力和能源系统已成为全球关键技术和经济发展的重点之一，该项目将在不同层面产生深远影响。这包括加强国家电力系统安全，为美国能源可持续发展界的政府机构和政策制定者提供技术支持，以及该领域的学生教育和劳动力准备。综合教育和外联办法还将提供一个独特的平台，鼓励妇女和少数族裔学生攻读关键的电气/计算机工程学科。

Growing energy demands and environmental concerns have significantly increased the interest of academia, industry, and governments in the development of a smart electric power grid. Security is one of the key aspects of power systems. The objective of this research is to advance methods of vulnerability analysis and to develop innovative responses to maintain the integrity of power grids under complex attacks (both cyber attacks and physical failures). This research will contribute to developing robust, secure, and reliable future smart grid systems. Unlike many of the existing efforts that focuses on abstract topological structure or load-based analysis, this project considers both network topology and intrinsic power flow characteristics to understand system behavior in complex power grid attacks. This includes single-node and multiple-node vulnerability analysis, development of new risk-aware metrics, spatial-temporal attacks with consideration of timing and location, and multifaceted attacks augmented by link failures. Knowledge of power grid system behavior under attack scenarios will allow us to develop new defense strategies. As power and energy systems have become one of the key technology and economic development focuses across the world, this project will have far-reaching impacts at different levels. This includes enhancing national power system security, providing technical support to government agencies and policy-makers for the U.S. energy sustainability community, and student education and workforce preparation in this field. The integrative educational and outreach approaches will also provide a unique platform to encourage women and minority students to the critical Electrical/Computer Engineering disciplines.
