Available in PDF, EPUB and Kindle. Book excerpt: Based on the author’s twenty years of experience, this book shows the practicality of modern, conceptually new, wide area voltage control in transmission and distribution smart grids, in detail. Evidence is given of the great advantages of this approach, as well as what can be gained by new control functionalities which modern technologies now available can provide. The distinction between solutions of wide area voltage regulation (V-WAR) and wide area voltage protection (V-WAP) are presented, demonstrating the proper synergy between them when they operate on the same power system as well as the simplicity and effectiveness of the protection solution in this case. The author provides an overview and detailed descriptions of voltage controls, distinguishing between generalities of underdeveloped, on-field operating applications and modern and available automatic control solutions, which are as yet not sufficiently known or perceived for what they are: practical, high-performance and reliable solutions. At the end of this thorough and complex preliminary analysis the reader sees the true benefits and limitations of more traditional voltage control solutions, and gains an understanding and appreciation of the innovative grid voltage control and protection solutions here proposed; solutions aimed at improving the security, efficiency and quality of electrical power system operation around the globe. Voltage Control and Protection in Electrical Power Systems: from System Components to Wide Area Control will help to show engineers working in electrical power companies and system operators the significant advantages of new control solutions and will also interest academic control researchers studying ways of increasing power system stability and efficiency.

This book was released on 2011-02 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most challenges in the development of smart grids today is the presence of phasor measurement units with modern communication facilities. The presence of such technologies will enable advanced smart grid applications that were not possible before such as the real time tracking of system dynamics. In addition, one of its goal issues is to maintain a high level of system stability. However, with rapid expansion of power system to meet the needs of the increasing demands of customers, and under the pressure of economical aspects placed by utilities to push the systems to operate very close to their limits, system wide disturbance become more likely. Therefore, the need for a systematic study and design of a comprehensive system control strategy is gaining more and more attention. Wide area protection is a concept of using system- wide information and sending selected local information to remote locations in order to mitigate the propagation of major disturbances. This book proposed a WAMPAC system with a defensive approach to counteract the transient instabilities in power systems. The system objective is to maximize the system stability and avoid occurrence of blackouts.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing issue of power-grid congestion and a global increase in disturbances have emphasized the need to enhance electrical power networks using Wide Area Monitoring, Protection, and Control (WAMPAC). This is a cost-effective solution for improving power system planning and operation. In addition to these existing issues, the Great Britain (GB) power system is facing significant changes, in terms of both power transmission technology and the nature of the generation mix, that will cause the operation of the future GB power system to become more unpredictable and complex. Therefore, developing a WAMPAC system will be essential to enhance the stability and optimise the operation of the future GB power system. The main objectives of the research presented in this thesis are to design a GB WAMPAC system and develop solutions to overcome the challenges that will be involved in the initial stage of the GB WAMPAC project. As Synchronized Measurement Technology (SMT) is the most essential element and enabler of WAMPAC, this thesis first provides a study of SMT and its applications. This study also reviews the state of the art of these SMT applications, and worldwide experience with the operation of WAMPAC in terms of system architecture, communication technologies and data management. After the basic study of WAMPAC, this thesis presents a new methodology for designing a roadmap that will ensure the future GB WAMPAC system will be developed in a logical and economic manner. This methodology takes into account the international experience with WAMPAC project management and the practical challenges faced in the future GB power system. With this new methodology, the GB strategies for the development of WAMPAC are devised. Two major SMT applications are then developed that can form main parts of the proposed future GB WAMPAC system. These applications are developed to enhance the small signal stability of the future GB power system.1. Wide Area Inter-area Oscillation Monitoring using Newton Type Algorithm.2. Wide Area Inter-area Oscillation Control using Power Electronic Devices. Finally, the operation of a proposed GB WAMPAC system is demonstrated using the DIgSILENT software package. The proposed real time applications are tested and evaluated using dynamic simulations of a full GB power system model. In addition, some key factors that will influence the operation of the future GB WAMPAC system will be analyzed and discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This book comprises a set of chapters that introduce various topics pertinent to novel approaches towards enhancing cyber-physical measures for increased security and resilience levels in control systems. The unifying theme of these approaches lies in the utilization of knowledge and models of the physical systems, rather than an attempt to reinvigorate conventional IT-based security measures. The contributing authors present perspectives on network security, game theory, and control, as well as views on how these disciplines can be combined to design resilient, safe, and secure control systems. The book explores how attacks in different forms, such as false data injections and denial-of-service can be very harmful, and may not be detected unless the security measures exploit the physical models. Several applications are discussed, power systems being considered most thoroughly. Because of its interdisciplinary nature—techniques from systems control, game theory, signal processing and computer science all make contributions—Security and Resilience of Control Systems will be of interest to academics, practitioners and graduate students with a broad spectrum of interests.

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.
