PI name: Lamine MiliInstitution: Virginia Polytechnic Institute & State UniversityProposal Number: 0835879Title: EFRI-RESIN: Resilient and Sustainable Interdependent Electric Power and Communications SystemsThis award is an outcome of the competition as part of the Emerging Frontiers in Research and Innovation (NSF 07-579) program solicitation under the subtopic Resilient and Sustainable Infrastructures (RESIN). The goal of this project is to develop complex systems theories and methods aimed at modeling, assessing, and reengineering the resiliency of sustainable interdependent electric power and communications infrastructures to catastrophic failures and natural hazards. Currently, the monitoring, protection, and control of electric power systems rely heavily on computer-based communications networks. Consequently, the failure of one infrastructure can affect the functioning of the other. This research will investigate the impact that these interdependencies have on the vulnerabilities of both infrastructures. It will suggest ways to make them more agile and resilient to anticipated and unanticipated failures and natural hazards while making the energy supply sustainable and less harmful to the environment. A new graduate course on risk management of critical infrastructures based on research results will be developed.One facet of the research is to extend the scope and applicability of the Highly Optimized Tolerance (HOT) approach to modeling cascading failures across interdependent electric power and communications infrastructures. The HOT method has previously been used with models involving only a single type of event and assumes that any multiple events of the same type are independent. This project will extend HOT to develop a risk function that involves not only several types of events but also dependent events to analyze the interdependent power and communication systems. To address the sustainability issue, the research will investigate the use of microgrids supplied with renewable and fossil distributed generation and energy storage systems. Previous research has suggested that a microgrid type of power distribution system is more resilient, e.g. less subject to a system wide failure, and more sustainable. This is due to a collection of appropriate incentives that can be provided to encourage customers to participate in energy conservation programs and to agree to rapid load shedding during emergency conditions to ensure grid survivability. In addition to HOT, another part of the research of this project will be to investigate financial impacts and required incentives to address resiliency and sustainability from the resource, environment and socioeconomic points of view.The project will use existing data from failures in the Southern Brazilian power and communications systems and from the North American Electric Reliability Council. The project will develop the theoretical foundations of a sustainability assessment framework (SAF) that uses two categories of quantitative measures: sustainability indicators and total cost functions. The SAF methods developed will rely on the concept of energy, which measures the effective amount of energy that can be converted into work.

项目名称：Lamine MiliInstitution: Virginia Polytechnic Institute & State university提案编号：0835879标题：EFRI-RESIN：弹性和可持续的相互依赖的电力和通信系统该奖项是竞赛的结果，是研究与创新新兴前沿（NSF 07-579）项目招标的一部分，子主题为弹性和可持续基础设施（RESIN）。该项目的目标是开发复杂的系统理论和方法，旨在对可持续的相互依赖的电力和通信基础设施进行建模、评估和重新设计，以应对灾难性故障和自然灾害。目前，电力系统的监测、保护和控制在很大程度上依赖于基于计算机的通信网络。因此，一个基础设施的故障可能会影响另一个基础设施的功能。本研究将调查这些相互依赖关系对两个基础设施的脆弱性的影响。它将提出一些方法，使它们对可预见和不可预见的故障和自然灾害更灵活、更有弹性，同时使能源供应可持续，对环境的危害更小。将在研究成果的基础上开设一门新的关于关键基础设施风险管理的研究生课程。研究的一个方面是扩展高度优化容限（HOT）方法的范围和适用性，以模拟相互依赖的电力和通信基础设施之间的级联故障。HOT方法以前用于只涉及单一类型事件的模型，并假设相同类型的任何多个事件都是独立的。该项目将扩展HOT，以开发不仅涉及几种事件类型的风险函数，还包括依赖事件，以分析相互依赖的电力和通信系统。为了解决可持续性问题，该研究将调查使用可再生能源和化石能源分布式发电和储能系统的微电网。先前的研究表明，微电网类型的配电系统更具弹性，例如更少受到系统范围故障的影响，并且更具可持续性。这是由于可以提供一系列适当的激励措施，鼓励客户参与节能计划，并同意在紧急情况下快速减载，以确保电网的生存能力。除了HOT之外，该项目的另一部分研究将从资源、环境和社会经济的角度调查财务影响和所需的激励措施，以解决弹性和可持续性问题。该项目将使用巴西南部电力和通信系统故障的现有数据以及北美电力可靠性委员会的数据。该项目将发展可持续性评估框架（SAF）的理论基础，该框架使用两类定量措施：可持续性指标和总成本函数。开发的SAF方法将依赖于能量的概念，它测量可以转化为功的有效能量。
