Download or read book Computational Models for Line Failure Risk and Cascading Power Failures on Bulk Power Systems written by and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Thesis, we develop computational models for line failure risk and cascading power failures on bulk power systems. General reliability issues cost society billions of dollars and large blackouts from cascading power failures have an extreme impact on society and can lead to loss of life. We start by building an analytic formulation of the cascading simulation found in literature, formulating the problem as a multi-stage stochastic program with integer variables to model the decision-dependent uncertainty. This allows for the flexibility to include the cascading simulation in as a subproblem for optimization in long-term design problems. We then use the Monte Carlo simulation of the cascading process and large computational resources of HTCondor to optimize transmission capacity expansion to reduce the expected value of load shed for a set of initial contingencies. The second half of the thesis focuses on the five minute dispatch market for power systems. We develop a system risk measure that is a joint chance constraint on the probability that one or more lines fail, which we constrain to be a small number. We model the probability that one line fails as a piecewise linear function. Additionally, we model uncertainty in generation and demand as a multivariate Gaussian and form a linear approximation of our system risk measure under uncertainty. We solve this large, convex problem using cutting planes. In order to account for exogenous contingencies, we model the N-1 contingencies and apply our risk measure under uncertainty. Finally, we find weights to measure the impact of losing a particular transmission line using the cascading simulation to evaluate rare event stress. We use these weights in a new weighted version of a joint chance constraint with N-1 contingency and solve with cutting planes. These computational models explore rare event stress through the cascade simulation. They incorporate uncertainty in demand, the initial contingencies that start cascades, and the uncertainty in cascade evolution. The first two models look at long term design problems given a budget to improve infrastructure and the last two models look at the five minute market to reduce rare event risk.

This book was released on 2010-04-13 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable and resilient critical infrastructure systems is an emerging paradigm in an evolving era of depleting assets in the midst of natural and man-made threats to provide a sustainable and high quality of life with optimized resources from social, economic, societal and environmental considerations. The increasing complexity and interconnectedness of civil and other interdependent infrastructure systems (electric power, energy, cyber-infrastructures, etc.) require inter- and multidisciplinary expertise required to engineer, monitor, and sustain these distributed large-scale complex adaptive infrastructure systems. This edited book is motivated by recent advances in simulation, modeling, sensing, communications/information, and intelligent and sustainable technologies that have resulted in the development of sophisticated methodologies and instruments to design, characterize, optimize, and evaluate critical infrastructure systems, their resilience, and their condition and the factors that cause their deterioration. Specific topics discussed in this book include, but are not limited to: optimal infrastructure investment allocation for sustainability, framework for manifestation of tacit critical infrastructure knowledge, interdependencies between energy and transportation systems for national long term planning, intelligent transportation infrastructure technologies, emergent research issues in infrastructure interdependence research, framework for assessing the resilience of infrastructure and economic systems, maintenance optimization for heterogeneous infrastructure systems, optimal emergency infrastructure inspection scheduling, and sustainable rehabilitation of deteriorated transportation infrastructure systems.

Download or read book Risk and Interdependencies in Critical Infrastructures written by Per Hokstad and published by Springer Science & Business Media. This book was released on 2012-12-18 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today’s society is completely dependent on critical networks such as water supply, sewage, electricity, ICT and transportation. Risk and vulnerability analyses are needed to grasp the impact of threats and hazards. However, these become quite complex as there are strong interdependencies both within and between infrastructure systems. Risk and Interdependencies in Critical Infrastructures: A guideline for analysis provides methods for analyzing risks and interdependencies of critical infrastructures. A number of analysis approaches are described and are adapted to each of these infrastructures. Various approaches are also revised, and all are supported by several examples and illustrations. Particular emphasis is given to the analysis of various interdependencies that often exist between the infrastructures. Risk and Interdependencies in Critical Infrastructures: A guideline for analysis provides a good tool to identify the hazards that are threatening your infrastructures, and will enhance the understanding on how these threats can propagate throughout the system and also affect other infrastructures, thereby identifying useful risk reducing measures. It is essential reading for municipalities and infrastructure owners that are obliged to know about and prepare for the risks and vulnerabilities of the critical infrastructures for which they are responsible.

Download or read book Cyber Security in Critical Infrastructures written by Stefan Rass and published by Springer Nature. This book was released on 2020-06-24 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a compendium of selected game- and decision-theoretic models to achieve and assess the security of critical infrastructures. Given contemporary reports on security incidents of various kinds, we can see a paradigm shift to attacks of an increasingly heterogeneous nature, combining different techniques into what we know as an advanced persistent threat. Security precautions must match these diverse threat patterns in an equally diverse manner; in response, this book provides a wealth of techniques for protection and mitigation. Much traditional security research has a narrow focus on specific attack scenarios or applications, and strives to make an attack “practically impossible.” A more recent approach to security views it as a scenario in which the cost of an attack exceeds the potential reward. This does not rule out the possibility of an attack but minimizes its likelihood to the least possible risk. The book follows this economic definition of security, offering a management scientific view that seeks a balance between security investments and their resulting benefits. It focuses on optimization of resources in light of threats such as terrorism and advanced persistent threats. Drawing on the authors’ experience and inspired by real case studies, the book provides a systematic approach to critical infrastructure security and resilience. Presenting a mixture of theoretical work and practical success stories, the book is chiefly intended for students and practitioners seeking an introduction to game- and decision-theoretic techniques for security. The required mathematical concepts are self-contained, rigorously introduced, and illustrated by case studies. The book also provides software tools that help guide readers in the practical use of the scientific models and computational frameworks.

Download or read book Optimization of Large scale Heterogeneous System of systems Models written by and published by . This book was released on 2012 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision makers increasingly rely on large-scale computational models to simulate and analyze complex man-made systems. For example, computational models of national infrastructures are being used to inform government policy, assess economic and national security risks, evaluate infrastructure interdependencies, and plan for the growth and evolution of infrastructure capabilities. A major challenge for decision makers is the analysis of national-scale models that are composed of interacting systems: effective integration of system models is difficult, there are many parameters to analyze in these systems, and fundamental modeling uncertainties complicate analysis. This project is developing optimization methods to effectively represent and analyze large-scale heterogeneous system of systems (HSoS) models, which have emerged as a promising approach for describing such complex man-made systems. These optimization methods enable decision makers to predict future system behavior, manage system risk, assess tradeoffs between system criteria, and identify critical modeling uncertainties.
