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（厄玛和玛丽亚），造成重大经济损失。 许多客户的电力损失是由于倒塌的建筑物、故障线路以及风暴后无法立即恢复电网运营造成的。 飓风“厄玛”和“玛丽亚”的影响与预计的自然灾害增加的频率和强度一致。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的历史。 其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证据，项目团队可以提供有价值的信息，帮助通过战略和优化流程提高电网的弹性。智力优势：这项研究是多所大学，杜克能源和波多黎各电力局（PREPA）之间的共同努力。 将开发一个网站来托管该项目，并将驻留在一个安全的服务器系统中。该小组将把数据上传到安全网站，并利用收集到的数据和风暴事件历史，在地理信息系统框架内进行地理时空综合分析。这项工作将调查故障模式和故障历史，以便根据现有电网系统的脆弱性和关键重要性从战略上评估风险。更广泛的影响：飓风厄玛和玛丽亚引起了国家和国际科学和工程组织以及公众的兴趣。关注公众提出的关键问题是，这种风暴是未来极端事件的例子，以及电力输送系统如何更具弹性。 收集的数据还将帮助沿海公用事业评估建立抵御极端天气的弹性电网系统的可行性。 通过分析这一法医研究收集的数据，将能够评估与欠发达地区相比，发达地区电网受到的影响。 这样的比较不仅对波多黎各，而且对全世界的未来电网现代化投资都是非常宝贵的。
