CAREER: Reliability Engineering for Electrical Energy Systems 2020: Smart Grid Applications and Beyond

目标：这项研究的目标是创建可靠性工程工具，以应对未来电力系统的规划和运行挑战。这些工具将侧重于i)量化网络和物理部件之间的耦合对可靠性的影响，ii)量化系统动力学和部件应力之间的耦合对可靠性的影响，以及iii)实现有效容错的机制。这种方法是根据电力系统的独特结构特征定制可靠性和控制论工具的混合。智力上的好处：这项研究将提供电力系统网络组件中的故障分类。将使用切换系统稳定性的结果来构建评估这些故障影响的分析模型。随机混合系统形式化将被用来提供一个分析框架来捕捉系统动力学和部件应力之间的相互作用。电力系统中的故障诊断主要局限于物理元件，对容错至关重要。开关系统可逆性技术将被用于解决网络组件的故障诊断。广泛的影响：这项研究将通过为设计更可靠和更灵敏的电力系统提供工具，推动智能电网的愿景。在教育方面，目标是开发材料，为培训下一代电力工程师提供与该项目相关的学科--电力系统、可靠性和控制--的统一视图。国际学生联合会将与教育公平项目办公室和伊利诺伊大学少数族裔学生事务办公室合作，以吸引代表不足的少数族裔。

Objectives;The objective of this research is to create reliability engineering tools to address planning and operation challenges of future electrical energy systems. These tools will focus on i) quantifying the impact of coupling between cyber and physical components on reliability, ii) quantifying the impact of coupling between system dynamics and component stress on reliability, and iii) implementing mechanisms for effective fault tolerance. The approach is to tailor a blend of reliability- and control-theoretic tools to the unique structural features of electrical energy systems.Intellectual Merit:This research will provide a taxonomy of faults in cyber components of electrical energy systems. Analytical models to assess the impact of these faults will be constructed using results from switched system stability. Stochastic hybrid system formalisms will be used to provide an analytical framework for capturing the interplay between system dynamics and component stress. Fault diagnosis in electrical energy systems, which has been primarily restricted to physical components, is paramount for fault tolerance. Switched system invertibility techniques will be utilized to address fault diagnosis of cyber components.Broader Impacts:This research will forward the Smart Grid vision by providing tools for engineering more reliable and responsive electrical energy systems. Educationally, the goal is to develop materials that provide a unified view of the disciplines relevant to this project - electrical energy systems, reliability, and control - for training the next generation of power engineers.
