Collaborative Research: Damage Assessment, Control, and Restoration of the Electric Power Grid Following Catastrophic Disturbances

本提案探讨了灾难性干扰后电网损害评估、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，以及大的电力影响，如短路和主要部件的故障。人为灾难，比如恐怖袭击，以及人为失误。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，c)危害程度。这种类型的分析将需要一个完善的信息和传感系统的投入。由于电力运输系统在地理上的广泛分布，问题的复杂性进一步增加。包括GPS、微波网络、互联网、低地球轨道卫星和其他通信网络在内的广泛通信技术的使用将作为信息的一部分进行审查。基础设施。与实时信息的调度和处理有关的问题也将被仔细审查。确定了支持大型电网实时监控和数据采集的计算和通信基础设施的关键要求。将提出满足这些要求的信息和计算体系结构。各种控制策略，以防止和最大限度地减少电网的错位程度将进行比较。将提出适用于电网的优雅退化的概念。这方面的工作还将涉及纠正战略，以促进快速恢复。还将探索配电网及其控制和保护设备的新配置，使电网以更可控的方式应对突发事件。调查的最后一步将处理在灾难性干扰后恢复系统的方法。这是对大型电网分析最少的方面之一。这是一项非常复杂的工作，涉及到与自动恢复有关的几个问题，以及涉及各种人力问题的手动切换。值得注意的是，电力输送网络由几个分层信息和控制网络覆盖，这些网络提供各种功能，处理监管、数据采集和在新的解除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。

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.
