This book was released on 2018 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2017-10-25 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2021 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2012-11-25 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electric power delivery system that carries electricity from large central generators to customers could be severely damaged by a small number of well-informed attackers. The system is inherently vulnerable because transmission lines may span hundreds of miles, and many key facilities are unguarded. This vulnerability is exacerbated by the fact that the power grid, most of which was originally designed to meet the needs of individual vertically integrated utilities, is being used to move power between regions to support the needs of competitive markets for power generation. Primarily because of ambiguities introduced as a result of recent restricting the of the industry and cost pressures from consumers and regulators, investment to strengthen and upgrade the grid has lagged, with the result that many parts of the bulk high-voltage system are heavily stressed. Electric systems are not designed to withstand or quickly recover from damage inflicted simultaneously on multiple components. Such an attack could be carried out by knowledgeable attackers with little risk of detection or interdiction. Further well-planned and coordinated attacks by terrorists could leave the electric power system in a large region of the country at least partially disabled for a very long time. Although there are many examples of terrorist and military attacks on power systems elsewhere in the world, at the time of this study international terrorists have shown limited interest in attacking the U.S. power grid. However, that should not be a basis for complacency. Because all parts of the economy, as well as human health and welfare, depend on electricity, the results could be devastating. Terrorism and the Electric Power Delivery System focuses on measures that could make the power delivery system less vulnerable to attacks, restore power faster after an attack, and make critical services less vulnerable while the delivery of conventional electric power has been disrupted.

Download or read book Quantifying and Improving Resilience in Power Distribution Systems written by Shiva Poudel and published by . This book was released on 2020 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme weather events have a significant impact on the aging and outdated power distribution infrastructures resulting in extended outages and loss of critical services. This calls for the need to ensure resilience in distribution networks by quickly restoring the critical services during a disaster. Unfortunately, the power distribution systems are traditionally designed and operated for known and credible threats and, therefore, are not resilient to extreme events. Fortunately, the aggressive deployment of smart grid technologies provides a source for improving efficiency, reliability, and resilience. The focus of this dissertation is to develop enablers for leveraging the smart grid technologies to enhance the resilience of the distribution networks. Towards this goal, we make the following three major contributions in this dissertation.First, we develop a probabilistic metric to quantify the operational resilience of the distribution grid. The metric is based on Conditional Value-at-Risk (CVaR) measure, where resilience is defined as the conditional expectation of the loss of energy in MWh for events beyond a pre-specified risk threshold. A simulation-based framework to evaluate the proposed metric including the impacts of smart actions, specifically improved restoration and infrastructure hardening on the resilience metric is presented. Second, we investigate the approaches for resilient restoration of power distribution networks using distributed energy resources (DERs). The proposed framework restores critical loads in the feeder while maximizing the post-restoration reliability of restored loads, including tie switches and open-loop distribution system configurations into the optimization formulation, and optimally allocating DERs for an equitable restoration of the critical loads. Further, we also present a new unified decision-making framework that can assist in recovery from both minor and major disruptions in a computationally tractable manner while efficiently utilizing DERs. The proposed formulation is a unified framework to support both the traditional restoration using feeder reconfiguration and the grid-forming DER-assisted intentional islanding methods. Third, we integrate a fault location, isolation, and service restoration (FLISR) application on an ADMS environment using the GridAPPS-D platform. The successful deployment of the FLISR application on the GridAPPS-D platform provides a proof-of-concept for the adoption of advanced applications to support future distribution systems.

Available in PDF, EPUB and Kindle. Book excerpt: The resilience issues in the power system have attracted increasing attention worldwide, especially for the distribution systems that suffer from extreme weather events, such as hurricanes and wildfire. In this dissertation, several novel algorithms, such as safe reinforcement learning algorithm and risk-constrained adaptive robust optimization approach are proposed to provide resilient proactive scheduling strategies, emergency response strategy and restoration strategy for central controllers in the distribution system. Microgrids are proposed to serve as single entities from the perspective of the distribution system operator to enhance the resilience of the distribution system, reduce the distribution system operator's control burden and improve the power quality of the distribution system. Uncertainties related with the extreme weather events such as power generation of distributed generators, intermittent load demand, point-of-common-coupling/tie-line conditions, and trend/trace of the extreme weather event are tackled through a combination of optimization approaches, artificial intelligence algorithms and risk management methods. Extensive simulation results based on real-world data sets show that the proposed novel algorithms based proactive scheduling strategies, emergence response strategy and restoration strategy can ensure the resilience of the distribution system in a real-world environment.
