This project aims at developing a comprehensive framework and the supporting theory for increasing resiliency of the critical electric power grid infrastructure in response to hurricanes and accordingly expediting recovery process for minimizing the associated economic, social, and physical disruptions. This research has profound impacts on local and national energy security, reliability, and sustainability by promoting the sound development of advanced techniques related to extreme weather events and natural disasters which are identified as the second cause of the largest blackouts in the United States. The project results will directly impact the society through helping electric power grid operators better manage available resources, reducing aftermath of hurricanes and other natural disasters, and accordingly saving billions of dollars in electric power grid outage and recovery related costs. This research will increase public awareness and facilitate the understanding of the complexity of hurricanes and the required recovery plans among stakeholders, ratepayers, regulators, utility executives, and market participants. Furthermore, this research will enable a rapid and wide-spread deployment of new technologies in smart grid, which will create substantial job opportunities in this area. In a broader scope, the project will promote teaching and training of future workforce, broaden participation of underrepresented groups, enhance research and education, and improve scientific and technological understanding via planned education and outreach activities as well as dissemination of findings to academia, industry, and the general public.In order to fulfill research objectives and present a significant change in current electric power grid response and recovery schemes, a framework for Proactive Recovery of Electric Power Assets for Resiliency Enhancement (PREPARE) will be developed. Within this framework, which will present the next generation decision making tool for proactive recovery, several coordinated models will be developed including (1) outage models to indicate the impact of hurricanes on power system components, (2) a stochastic pre-hurricane crew mobilization model for managing resources before the event, (3) a deterministic post-hurricane recovery model for managing resources after the event, and (4) outage and repair models to be incorporated in crew mobilization and recovery models. The models will be extended to ensure applicability to a variety of electric power grids with different technologies and regulatory issues. The stochastic pre-hurricane crew mobilization model will be developed using latest advances in mathematical optimization, which includes Monte Carlo Sampling, Recourse Modeling, and Chance Constraint Modeling, to find the best suited approach. The framework will be validated and its applicability to large-scale practical electric power grids will be verified by leveraging the data obtained from the electric utility collaborator of the project. The theoretical and practical implications of the developed results will push the research frontier of proactive response and recovery schemes in electric power grids. The transformative nature of this research supports application to a variety of infrastructures, and in response to a wide range of extreme weather events and natural disasters.

该项目旨在开发一个全面的框架和支持理论，以提高关键电网基础设施应对飓风的弹性，从而加快恢复过程，最大限度地减少相关的经济、社会和物理破坏。这项研究通过促进与极端天气事件和自然灾害相关的先进技术的健全发展，对地方和国家的能源安全、可靠性和可持续性产生深远影响，极端天气事件和自然灾害被认为是美国最大规模停电的第二个原因。该项目的成果将直接影响社会，帮助电网运营商更好地管理可用资源，减少飓风和其他自然灾害的后果，从而节省数十亿美元的电网停电和恢复相关成本。这项研究将提高公众意识，促进利益相关者、纳税人、监管机构、公用事业高管和市场参与者对飓风复杂性和所需恢复计划的理解。此外，这项研究还将促进智能电网新技术的快速、广泛部署，从而在该领域创造大量就业机会。在更广泛的范围内，该项目将促进未来劳动力的教学和培训，扩大代表性不足群体的参与，加强研究和教育，并通过有计划的教育和推广活动以及向学术界、工业界和学术界传播研究结果来提高科学技术理解。为了实现研究目标并呈现当前电网响应和恢复方案的重大变化，将开发电力资产主动恢复以增强抗灾能力（PREPARE）的框架。在此框架内，将提出用于主动恢复的下一代决策工具，将开发几个协调模型，包括（1）断电模型，以表明飓风对电力系统组件的影响，（2）飓风前随机人员动员用于在事件发生前管理资源的模型；(3) 用于在事件发生后管理资源的确定性飓风后恢复模型；(4) 将纳入人员动员和恢复模型的停电和维修模型。这些模型将得到扩展，以确保适用于具有不同技术和监管问题的各种电网。飓风前的随机人员动员模型将利用数学优化的最新进展（包括蒙特卡罗采样、资源建模和机会约束建模）来开发，以找到最适合的方法。将利用从该项目的电力公司合作者获得的数据对该框架进行验证，并验证其对大规模实际电网的适用性。该成果的理论和实践意义将推动电网主动响应和恢复方案的研究前沿。这项研究的变革性性质支持应用于各种基础设施，并应对各种极端天气事件和自然灾害。
