This proposal explores new concepts for the damage assessment, control, and restoration of the electric power grid following catastrophic disturbances. These disturbances would include:1. Natural disasters like earthquakes, tornadoes, ice storms, wind storms, and large electrical impacts like short circuits, and failure of major components.2. Man-made disasters, such as terrorist attacks, and human errors.The damage assessment consists of determining the severity based on the following criteria:a) Degree of damage, b) Degree of danger, and c) Extent of hazard. This type of analysis will require input from a well-established information and sensing system. The complexity of the problem is further increased because of the large geographical expanse of the Electric Power Transportation system. The use of a wide array of communication technologies including GPS, Microwave Networks, Internet, low earth orbit satellites, and other communication networks will be examined as a part of the information. Infrastructure.Issues related to the scheduling and processing of real time information will also be carefully examined. Key requirements for the computing and communication infracture to support real time supervisory control and data acquisition of large electric power grids are identified. Information and computing architectures to meet these requirements will be proposed.Various control strategies to prevent and minimize the extent of the dislocation of the electric network will be compared. Concepts of graceful degradation as applied to the electric power grid will be proposed. This aspect of the work would also involve corrective strategies to facilitate fast restoration. Newer configurations for the electric power distribution networks and their control and protection equipment so that the network responds to emergencies in a more controlled manner will also be explored.The final step in the investigation will deal with approaches for the restoration of the system following catastrophic disturbances. This is one of the least analyzed aspects of large power grids. It is a highly complex undertaking and involves several issues that relate to automatic restoration as will as manual switching that involves a variety of manpower issues.It is important to note that the power delivery network is overlayed with several hierarchical information and control networks that provide various functions dealing with supervisory control data acquisition, and transaction information in the new deregulated electric utility environment. The roles of each network layer will also be carefully identified.

该提案探讨了灾难性干扰后电网的损害评估、控制和恢复的新概念。这些干扰包括：1。自然灾害，如地震、龙卷风、冰暴、风暴和大型电力冲击， 短路和主要部件故障。人为灾害，如恐怖袭击和人为错误。损害评估包括根据以下标准确定严重程度：a）损害程度，B）危险程度，以及c）危害程度。这类分析将需要来自完善的信息和传感系统的投入。由于电力运输系统的地理范围很广，问题的复杂性进一步增加。作为信息的一部分，将审查包括全球定位系统、微波网络、互联网、低地球轨道卫星和其他通信网络在内的各种通信技术的使用情况。基础设施。还将仔细审查与真实的时间信息的安排和处理有关的问题。确定了支持大型电网真实的实时监控和数据采集的计算和通信基础设施的关键要求。我们将提出满足这些要求的信息和计算体系结构，并将比较防止和最小化电网失调程度的各种控制策略。将提出适用于电力网的优雅退化的概念。这方面的工作还将涉及促进快速恢复的纠正战略。此外，还将探讨配电网及其控制和保护设备的新配置，以便配电网以更可控的方式对紧急情况作出反应。调查的最后一步将涉及在发生灾难性干扰后恢复系统的方法。这是大型电网分析最少的方面之一。这是一项高度复杂的工作，涉及到自动恢复以及涉及到各种人力问题的手动切换的几个问题。重要的是要注意，电力输送网络覆盖有几个分层信息和控制网络，这些网络提供处理监督控制数据采集的各种功能，以及在新的放松管制的电力公用事业环境中的交易信息。每个网络层的角色也将被仔细识别。
