The electric grid in the United States has evolved over the past century from a series of small independent community-based systems to one of the largest and most complex cyber-physical systems today. However, the established conditions that made the electric grid an engineering marvel are being challenged by major changes, the most important being a worldwide effort to mitigate climate change by reducing carbon emissions.This research investigates key aspects of a computation and information foundation for future cyber-physical energy systems?the smart grids. The overall project objective is to support high penetrations of renewable energy sources, community based micro-grids, and the widespread use of electric cars and smart appliances.The research has three interconnected components that, collectively, address issues of computation architecture, information hierarchy, and experimental modeling and validation. On computation architecture, the framework based on cloud computing is investigated for the scalable, consistent, and secure operations of smart grids. The research aims to quantify fundamental design tradeoffs among scalability, data consistency, security, and trustworthiness for emerging applications of smart grids. On information hierarchy, temporal and spatial characteristics of information hierarchy are investigated with the goal of gaining a foundational understanding on how information should be partitioned, collected, distributed, compressed, and aggregated. The research also develops an open and scalable experimental platform (SmartGridLab) for empirical investigations and testing of algorithms and concepts developed in this project. SmartGridLab integrates the hardware testbed with a software simulator so that software virtual nodes can interact with physical nodes in the testbed. This research also includes a significant education component aimed at integrating frontier research with undergraduate and graduate curricula.

在过去的世纪里，美国的电网已经从一系列独立的小型社区系统发展成为当今最大和最复杂的网络物理系统之一。 然而，使电网成为工程奇迹的既定条件正在受到重大变化的挑战，最重要的是世界范围内通过减少碳排放来缓解气候变化的努力。智能电网。整个项目的目标是支持可再生能源的高渗透率，基于社区的微电网，以及电动汽车和智能家电的广泛使用。该研究有三个相互关联的组成部分，共同解决计算架构，信息层次结构和实验建模和验证问题。 在计算架构方面，研究了基于云计算的智能电网可扩展、一致和安全运行框架。该研究旨在量化智能电网新兴应用的可扩展性，数据一致性，安全性和可信度之间的基本设计权衡。在信息层次结构方面，研究了信息层次结构的时间和空间特征，目的是对信息如何划分、收集、分布、压缩和聚合有一个基本的了解。该研究还开发了一个开放和可扩展的实验平台（SmartGridLab），用于实证调查和测试该项目中开发的算法和概念。SmartGridLab将硬件测试床与软件模拟器集成在一起，以便软件虚拟节点可以与测试床中的物理节点进行交互。 这项研究还包括一个重要的教育组成部分，旨在将前沿研究与本科和研究生课程相结合。
