The 2017 hurricane season inflicted two severe blows (Irma and Maria) to the Atlantic region of the U.S. resulting in significant economic losses. Power losses for many customers resulted from collapsed structures, faulted lines, and the inability to resurrect electrical power grid operations immediately after the storm. The effects of Hurricanes Irma and Maria are consistent with projected increases in natural disasters, both in terms of frequency and intensity. This study investigates the aftermaths of the hurricanes and reconstructs the power grid failure history through forensic analytics. The intent is to identify critical elements in the design of a resilient system. By collecting the perishable evidence from these extreme events, the project team can provide valuable information to help improve the resilience of electrical power grids through a strategic and optimized process.Intellectual Merit: This research is a joint effort between multiple universities, Duke Energy and Puerto Rico Electric Power Authority (PREPA). A website will be developed to host the project and will reside in a secured server system. The team will upload the data to the secured website and use the collected data and storm event history to generate the geospatial-temporal integrated analysis within a GIS framework. This work will investigate failure patterns and failure history in order to strategically assess risk based on vulnerabilities and critical importance of the existing grid systems.Broader Impact: Hurricanes Irma and Maria have the interest of national and international scientific and engineering organizations and the general public. The critical question raised by a concerned public are such storms examples of future extreme events and how can the power delivery systems be more resilient. The collected data will also help coastal utilities evaluate the viability of building a resilient grid system that resists extreme weather. The analysis of the data gathered by this forensic study will allow an evaluation of the effects on the grid in well-developed areas compared to less-developed areas. Such a comparison can be invaluable in designing future grid modernization investments not only in Puerto Rico but also around the world.

2017年飓风季节对美国大西洋地区造成了两次严重打击（Irma和Maria），造成了巨大的经济损失。 许多客户的电力损失是由于崩溃的结构，故障线路以及暴风雨后立即无力复活的电力电网操作而导致的。 在频率和强度方面，飓风Irma和Maria的影响与自然灾害的预计增加一致。这项研究调查了飓风的后果，并通过法医分析重建了电网故障历史记录。 目的是确定弹性系统设计中的关键要素。通过从这些极端事件中收集易腐烂的证据，项目团队可以通过战略和优化的过程来提供有价值的信息，以帮助提高电力网格的弹性。智慧优点：这项研究是多个大学，杜克大学能源和波多黎各电力电力公司（PREPA）之间的共同努力。 将开发网站以托管该项目，并将居住在安全的服务器系统中。该团队将将数据上传到有担保网站，并使用收集的数据和风暴事件历史记录在GIS框架内生成地理空间范围的集成分析。这项工作将调查故障模式和失败历史记录，以便基于脆弱性和现有网格系统的至关重要来战略评估风险。BOADER的影响：Irma和Maria飓风具有国家和国际科学和工程组织以及一般公众的兴趣。相关公众提出的关键问题是这样的风暴例子，说明了未来的极端事件，以及电力输送系统如何更具弹性。 收集到的数据还将帮助沿海公用事业评估构建抗韧性网格系统的生存能力，以抵抗极端天气。 这项法医研究对数据收集的数据的分析将允许评估与发达地区相比，发达区域中对网格的影响。 这种比较在设计未来的电网现代化投资不仅在波多黎各，而且在世界各地也是无价的。
