The resiliency of the electric power grid to extreme events is a fundamental motivation for modernizing the aging and vulnerable critical infrastructure. The alarming rise in the number of incidences of cyber-attacks and severe storms over the last few years have caused prolonged power outages for millions of customers. The financial impact of these events upon the utilities has been several hundred billions of dollars.The objective of this dissertation is to develop a comprehensive framework and algorithms for enabling resiliency of power distribution systems - encompassing time-span from planning to post-event restoration and recovery that would minimize the power outages resulting in less economic losses and public inconveniences.Some of the main challenges of the industry in planning - are the broad range of interpretations of power distribution system resiliency, based on the time available for preparing before an event happens and recovering afterward, and lack of detailed, region-specific distribution models. This dissertation addresses these problems extensively. A mathematical model for studying the propagation of extreme events in the cyber-physical power grid has also been discussed.Enabling resiliency in near-term or during the contingency requires the ability to perform power flow and restoration calculations for the impending or ongoing threat. Thus, an event-driven proactive network reconfiguration strategy has been proposed, to study how the path of propagation can impact the operation and restoration of the power distribution system.In the aftermath of an event, the distribution system infrastructure is characterized by uncertain topology, load demand, power resources, and time until power can be completely restored to all customers. In this work, the resiliency of the electric grid has been studied as a robust optimization problem for the effective allocation of scant resources to meet the demands of critical customers during prolonged periods of power outage.The proposed theory and algorithms in this dissertation have been tested on IEEE test systems as well as validated against actual data available from industry partners.

RESILIENCY OF POWER DISTRIBUTION SYSTEMS A revolutionary book covering the relevant concepts for resiliency-focused advancements of the distribution power grid Most resiliency and security guidelines for the power industry are focused on power transmission systems. As renewable energy and energy storage increasingly replace fossil-fuel-based power generation over the coming years, geospatially neighboring distributed energy resources will supply a majority of consumers and provide clean power through long transmission lines. These electric power distribution systems—the final stage in the delivery of electric power—carry electricity from the transmission system to individual consumers. New distributed devices will be essential to the grid to manage this variable power generation and enhance reliability and resilience while keeping electricity affordable as the world seeks solutions to climate change and threats from extreme events. In Resiliency of Power Distribution Systems, readers are provided with the tools to understand and enhance resiliency of distribution systems—and thereby, the entire power grid. In a shift from the present design and operation of the power system, the book is focused on improving the grid’s ability to predict, adapt, and respond to all hazards and threats. This, then, acts as a guide to ensure that any incident can be mitigated and responded to promptly and adequately. It also highlights the most advanced and applicable methodologies and architecture frameworks that evaluate degradation, advance proactive action, and transform system behavior to maintain normal operation, under extreme operating conditions. Resiliency of Power Distribution Systems readers will also find: Chapter organization that facilitates quick review of distribution fundamental and easy-but-thorough understanding of the importance of resiliency Real-world case studies where resilient power systems could have prevented massive financial and energy losses Frameworks to help mitigate cyber-physical attacks, strategize response on multiple timescales, and optimize operational efficiencies and priorities for the power grid Resiliency of Power Distribution Systems is a valuable reference for power system professionals including electrical engineers, utility operators, distribution system planners and engineers, and manufacturers, as well as members of the research community, energy market experts and policy makers, and graduate students on electrical engineering courses.

Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.

Distribution grid planners, engineers, and operators are increasingly observing resiliency as the primary design attribute for modern distribution systems to mitigate the impact of increasing extreme weather and cyber events threatening their system. Enabling distribution system resiliency is a multi-step process that begins with the identification of the potential threats to the system, the quantification of the current resiliency of the system to the identified threats through the development of resiliency metrics, proposing resiliency improvements and finally, the evaluation of the resiliency improvement strategy. This process of enabling resiliency requires system-specific research and complex analysis tools beginning with sophisticated physical and cyber system models, resiliency metrics for quantification, planning methods to upgrade resiliency performance, operational strategies to mitigate the loss of resiliency, and controls of interdependent systems.This dissertation adds to the recent works on resiliency metrics, decision support for resiliency improvements, and presents novel strategies for increasing resiliency for microgrid/distribution grid systems. A multi-dimensional resiliency metric called the anticipate - withstand - recover (AWR) metric is used to evaluate the power distribution system's resiliency to physical and cyber threats. The work studies various planning and operational use cases for better situational awareness and resilient operation of distribution and microgrids. A set of prototypical communication network models is developed to address the lack of standard communication network models for the co-simulation of smart grid application. The algorithms developed in this work increase resiliency of the distribution grid/microgrid using targeted investments in resiliency enabling infrastructure, defense against cyber-attacks, black start restoration, and delay tolerance of communication sensitive microgrid applications.

This paper presents a method for quantifying and enabling the resiliency of a power distribution system (PDS) using analytical hierarchical process and percolation theory. Using this metric, quantitative analysis can be done to analyze the impact of possible control decisions to pro-actively enable the resilient operation of distribution system with multiple microgrids and other resources. Developed resiliency metric can also be used in short term distribution system planning. The benefits of being able to quantify resiliency can help distribution system planning engineers and operators to justify control actions, compare different reconfiguration algorithms, develop proactive control actions to avert power system outage due to impending catastrophic weather situations or other adverse events. Validation of the proposed method is done using modified CERTS microgrids and a modified industrial distribution system. Furthermore, simulation results show topological and composite metric considering power system characteristics to quantify the resiliency of a distribution system with the proposed methodology, and improvements in resiliency using two-stage reconfiguration algorithm and multiple microgrids.

No person or place is immune from disasters or disaster-related losses. Infectious disease outbreaks, acts of terrorism, social unrest, or financial disasters in addition to natural hazards can all lead to large-scale consequences for the nation and its communities. Communities and the nation thus face difficult fiscal, social, cultural, and environmental choices about the best ways to ensure basic security and quality of life against hazards, deliberate attacks, and disasters. Beyond the unquantifiable costs of injury and loss of life from disasters, statistics for 2011 alone indicate economic damages from natural disasters in the United States exceeded $55 billion, with 14 events costing more than a billion dollars in damages each. One way to reduce the impacts of disasters on the nation and its communities is to invest in enhancing resilience-the ability to prepare and plan for, absorb, recover from and more successfully adapt to adverse events. Disaster Resilience: A National Imperative addresses the broad issue of increasing the nation's resilience to disasters. This book defines "national resilience", describes the state of knowledge about resilience to hazards and disasters, and frames the main issues related to increasing resilience in the United States. It also provide goals, baseline conditions, or performance metrics for national resilience and outlines additional information, data, gaps, and/or obstacles that need to be addressed to increase the nation's resilience to disasters. Additionally, the book's authoring committee makes recommendations about the necessary approaches to elevate national resilience to disasters in the United States. Enhanced resilience allows better anticipation of disasters and better planning to reduce disaster losses-rather than waiting for an event to occur and paying for it afterward. Disaster Resilience confronts the topic of how to increase the nation's resilience to disasters through a vision of the characteristics of a resilient nation in the year 2030. Increasing disaster resilience is an imperative that requires the collective will of the nation and its communities. Although disasters will continue to occur, actions that move the nation from reactive approaches to disasters to a proactive stance where communities actively engage in enhancing resilience will reduce many of the broad societal and economic burdens that disasters can cause.
