项目摘要

This Critical Resilient Interdependent Infrastructure Systems and Processes (CRISP) project seeks to develop an evidence-based, economically sound and validated approach to enhancing the resilience of US electricity grids, accounting for their interdependence with the natural gas supply system. This project develops a robust and comprehensive technique to quantify how different types of actions and measures improve the resilience of an electric grid. Based on a harm function that unifies existing resilience metrics, the effectiveness of various network management options are quantified. Options include: changing the structure of the electric grid, hardening some components, expanding gas transmission and storage capacity, or boosting preparedness. This project also examines the optimal mix of resilience investments. Models will be validated using case studies in New England and Puerto Rico. This research is following a three step approach. In the first step, the researchers develop a harm function that unifies existing resilience metrics. This function is defined as the weighted sum of the outage time at different nodes of the network. Based on this metric, measures to improve the resilience of the grid can be rigorously quantified. In the second step, the researchers optimize resilience investments using equilibrium models of electricity markets that account for natural gas transmission constraints. In the third step, the algorithms, models and mechanisms are validated examining natural gas and grid test systems in the Northeastern U.S., with a focus on the New England region; and 2) the power system of Puerto Rico, which provides a unique opportunity to test and validate the methods in a real system undergoing an almost complete rebuild after a major disruption. The results of this project will be of interest to regulators concerned with long term investments in resilience that are effective and based on sound economic principles and regulatory practices. The techniques developed in this project will help electric utilities compare the effectiveness of various measures and justify the corresponding operating and capital expenditures to their regulators. The results will be disseminated through undergraduate and graduate infrastructure courses and workshops for utilities, ISOs and government agencies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该关键弹性相互依赖基础设施系统和流程 (CRISP) 项目旨在开发一种基于证据、经济合理且经过验证的方法，以增强美国电网的弹性，并解释其与天然气供应系统的相互依赖性。该项目开发了一种强大而全面的技术来量化不同类型的行动和措施如何提高电网的弹性。基于统一现有弹性指标的危害函数，可以量化各种网络管理选项的有效性。选项包括：改变电网结构、加固某些组件、扩大天然气传输和存储能力，或加强准备工作。该项目还研究了弹性投资的最佳组合。模型将通过新英格兰和波多黎各的案例研究进行验证。这项研究遵循三步法。第一步，研究人员开发了一个统一现有弹性指标的伤害函数。该函数定义为网络不同节点的中断时间的加权和。基于这个指标，可以严格量化提高电网弹性的措施。第二步，研究人员使用考虑了天然气传输限制的电力市场均衡模型来优化弹性投资。第三步，通过检查美国东北部（重点是新英格兰地区）的天然气和电网测试系统来验证算法、模型和机制； 2）波多黎各的电力系统，它提供了一个独特的机会来测试和验证在重大中断后几乎完全重建的真实系统中的方法。该项目的结果将引起关注对复原力进行长期投资的监管机构的兴趣，这些投资是有效的并基于健全的经济原则和监管实践。该项目开发的技术将帮助电力公司比较各种措施的有效性，并向监管机构证明相应的运营和资本支出的合理性。结果将通过本科生和研究生基础设施课程以及公用事业、ISO 和政府机构的研讨会进行传播。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
