The overall goal of this book is to introduce algorithms for improving the economic posture of a utility company in a restructured power system by promoting cost-effective maintenance schedules. This book's topic is very timely as the electric utility industry is undergoing a major restructuring, and what used to be vertically integrated is now being unbundled. The restructuring has given rise to a number of separate business entities with their own objectives. In this breakup, the issue of maintenance scheduling has been missed completely since none of these entities currently have explicit accountability for this subject. The authors offer a logical alternative to traditional electric utility maintenance practices and a basis for making maintenance decisions. Maintenance scheduling problems are formulated as decomposed problems. This signifies the nature of restructured power systems with self-interested entities and optimizes potential revenues while meeting constraints such as fuel schedules, emission constraints, hourly load demands, and network limits. Coordination of short- and long-term maintenance scheduling is also presented. The book shows by numerous derivations and examples that careful planning and good coordination among self-interested entities in restructured power systems are essential to achieving an optimal trade-off between the cost of maintenance and service reliability. Maintenance Scheduling in Restructured Power Systems includes a variety of models, solutions and ideas that will be invaluable to engineers, consultants, manufacturers, students, and others working and studying in the utility field.

The book also explains in detail how to set up measuring systems, data analysis, and PEM Fuel Cells' static and dynamic characteristics. Covered in detail are design and operation principles such as polarization phenomenon, thermodynamic analysis, and overall voltage; failure modes and mechanisms such as permanent faults, membrane degradation, and water management; and modelling and numerical simulation including semi-empirical, one-dimensional, two-dimensional, and three-dimensional models. It is appropriate for graduate students, researchers, and engineers who work with the design and reliability of hydrogen fuel cells, in particular proton exchange membrane fuel cells.
This book deals specifically with control theories relevant to the design of control units for switched power electronics devices, for the most part represented by DC DC converters and supplies, by rectifiers of different kinds and by inverters with varying topologies. The theoretical methods for designing controllers in linear and nonlinear systems are accompanied by multiple case studies and examples showing their application in the emerging field of power electronics.
This book describes the analysis and design of precision temperature sensors in CMOS IC technology. It focusses on so-called smart temperature sensors, which provide a digital output signal that can be readily interpreted by a computer. The sensors described in this book are based on bipolar transistors, which are available as parasitic devices in standard CMOS technology. The relevant physical properties of these devices are described. It is shown in detail how their temperature characteristics can be used to obtain an accurate digital temperature reading. A sigma-delta converter plays a key role in the conversion to a digital output. Both the system-level design of such a converter, and the circuit-level implementation using both continuous-time and switched-capacitor techniques are described. Special attention is paid to the application of precision interfacing techniques, such as dynamic offset cancellation and dynamic element matching. A separate chapter is devoted to low-cost calibration techniques. Precision Temperature Sensors in CMOS Technology ends with a detailed description of three realized prototypes. The final prototype achieves an inaccuracy of only A0.1AC (3Sigma) over the temperature range of a "55AC to 125AC, which is the highest performance reported to date.

The author studies carbon's ability to increase conductivity and to decrease material grain size, as well as investigating the electrochemical behaviour of the materials obtained. "Iron Phosphate Materials as Cathodes for Lithium Batteries" also proposes a model to explain lithium insertion/extraction in LiFePO4 and to predict voltage profiles at various discharge rates. "Iron Phosphate Materials as Cathodes for Lithium Batteries" is written for postgraduate students and researchers in electrochemistry, R&D professionals and experts in electrochemical storage.
This book is about how to avoid the accidents and injuries that may occur when batteries are abused or mishandled. It is the first book to deal specifically with this subject in a reasonably comprehensive manner accessible to readers ranging from regular consumers to technical specialists. Batteries and battery processes are described in sufficient detail to enable readers to understand why and how batteries cause accidents and what can be done to prevent them. Each year in the United States alone, thousands of individuals are injured by battery accidents, some of which are severely disabling. The tragedy is that such accidents need not occur. The book is intended to satisfy the needs of a varied group of readers: battery users in general, battery engineers, and designers of battery-operated equipment and consumer electronics. Since the book is a reference source of information on batteries and battery chemicals, we believe it may also be useful to those studying the environment as well as to medical personnel called upon to treat battery injuries. There are no prerequisites for an under standing of the text other than an interest in batteries and their safe usage."
Compression and Coding Algorithms describes in detail the coding
mechanisms that are available for use in data compression systems.
The well known Huffman coding technique is one mechanism, but there
have been many others developed over the past few decades, and this
book describes, explains and assesses them. People undertaking
research of software development in the areas of compression and
coding algorithms will find this book an indispensable reference.
In particular, the careful and detailed description of algorithms
and their implementation, plus accompanying pseudo-code that can be
readily implemented on computer, make this book a definitive
reference in an area currently without one.

A spherical actuator is a novel electric device that can achieve 2/3-DOF rotational motions in a single joint with electric power input. It has advantages such as compact structure, low mass/moment of inertia, fast response and non-singularities within the workspace. It has promising applications in robotics, automobile, manufacturing, medicine and aerospace industry. This is the first monograph that introduces the research on spherical actuators systematically. It broadens the scope of actuators from conventional single-axis to multi-axis, which will help both beginners and researchers to enhance their knowledge on electromagnetic actuators. Generic analytic modeling methods for magnetic field and torque output are developed, which can be applied to the development of other electromagnetic actuators. A parametric design methodology that allows fast analysis and design of spherical actuators for various applications is proposed. A novel non-contact high-precision 3-DOF spherical motion sensing methodology is developed and evaluated with experiments, which shows that it can achieve one order of magnitude higher precision than conventional methods. The technologies of nondimensionalization and normalization are introduced into magnetic field analysis the first time, and a benchmark database is established for the reference of other researches on spherical actuators.
In recent years it has become increasingly apparent that conventional electrical networks cannot meet the requirements of the 21st century. These include reliability, efficiency, liberalisation of electricity markets, as well as effective and seamless integration of various types of renewable energy sources, electric vehicles, and customers as players. The emergence of new technologies such as distributed control, monitoring devices, and tremendous advances in information and communication technology have paved the way to realize the Smart Grid concept. This book identifies and discusses the tools required to ensure the interoperability among the various digitally-based components of the Smart Grid. Topics covered include an introduction to the smart grid concept; smart grid versus conventional electric networks; smart grid infrastructure; interoperability standards; communication system and its cyber security; international standard IEC 61850 and its application to smart grids; power system protection under smart grid environment; application of smart grid concept to distribution networks; integration of electric vehicles; energy storage systems; and the smart transmission grid. Introduction to the Smart Grid: Concepts, technologies and evolution is essential reading for researchers, engineers and advanced students working in energy engineering.

The application of quantitative reliability evaluation in electric power sys tems has now evolved to the point at which most utilities use these techniques in one or more areas of their planning, design, and operation. Most of the techniques in use are based on analytical models and resulting analytical evaluation procedures. Improvements in and availability of high-speed digi tal computers have created the opportunity to analyze many of these prob lems using stochastic simulation methods and over the last decade there has been increased interest in and use made of Monte Carlo simulation in quantitative power system reliability assessment. Monte Carlo simulation is not a new concept and recorded applications have existed for at least 50 yr. However, localized high-speed computers with large-capacity storage have made Monte Carlo simulation an available and sometimes preferable option for many power system reliability applications. Monte Carlo simulation is also an integral part of a modern undergrad uate or graduate course on reliability evaluation of general engineering systems or specialized areas such as electric power systems. It is hoped that this textbook will help formalize the many existing applications of Monte Carlo simulation and assist in their integration in teaching programs. This book presents the basic concepts associated with Monte Carlo simulation."
This book presents a thorough analysis of newly available sinusoidal three-phase windings in electrical machines, which provide many benefits over traditional windings, including energy savings, noise and vibration reduction, and reduced need for non-ferrous metals. The author's instruction on the implementation of this innovative optimization will be quite useful to researchers, developers and producers of electrical machines, as well as students mastering electromechanics.
This work provides an in-depth case-study of decision-making in the Soviet Union in the Stalin era. It focuses on the development of rail transport policy, upon which the entire economy as well as the country's defence were so crucially dependent. It analyses the role of institutional lobbies in shaping policy, and sheds new light on the Stakhanovite movement, and analyses for the first time the impact of the Great Purges on the railways. The work provides a critical examination of the adequacy of existing conceptualisations of the Stalinist state.
What lies beyond the era of fossil fuels? While most answers focus on different primary energy resources, "Energy Systems in the Era of Energy Vectors" provides a completely new approach. Instead of providing a traditional consumption analysis of classical primary energy resources such as oil, coal, nuclear power and gas, "Energy Systems in the Era of Energy Vectors" describes and assesses energy technologies, markets and future strategies, focusing on their capacity to produce, exchange, and use energy vectors. Special attention is given to the renewable energy resources available in different areas of the world and made exploitable by the integration of energy vectors in the global energy system. Clear definitions of energy vectors and energy systems are used as the basis for a complete explanation and assessment of up-to-date, available technologies for energy resources, transport and storage systems, conversion and use. The energy vectors scheme allows the potential realization of a worldwide sustainable energy system to fulfill global development expectations by minimizing both the impact on the environment, and the international political frictions for access to limited and concentrated resources. "Energy Systems in the Era of Energy Vectors" is an informative read for researchers and advanced students in industrial, energy and environmental engineering. It also contains valuable information for managers and technicians working in the energy sector.
This book presents developments and new results on complex differential-difference equations, an area with important and interesting applications, which also gathers increasing attention.

High-Level Power Analysis and Optimization presents a comprehensive description of power analysis and optimization techniques at the higher (architecture and behavior) levels of the design hierarchy, which are often the levels that yield the most power savings. This book describes power estimation and optimization techniques for use during high-level (behavioral synthesis), as well as for designs expressed at the register-transfer or architecture level. High-Level Power Analysis and Optimization surveys the state-of-the-art research on the following topics: power estimation/macromodeling techniques for architecture-level designs, high-level power management techniques, and high-level synthesis optimizations for low power. High-Level Power Analysis and Optimization will be very useful reading for students, researchers, designers, design methodology developers, and EDA tool developers who are interested in low-power VLSI design or high-level design methodologies.
This book is about large-scale electronic circuits design driven by nanotechnology, where nanotechnology is broadly defined as building circuits using nanoscale devices that are either implemented with nanomaterials (e.g., nanotubes or nanowires) or following an unconventional method (e.g., FinFET or III/V compound-based devices). These nanoscale devices have significant potential to revolutionize the fabrication and integration of electronic systems and scale beyond the perceived scaling limitations of traditional CMOS. While innovations in nanotechnology originate at the individual device level, realizing the true impact of electronic systems demands that these device-level capabilities be translated into system-level benefits. This is the first book to focus on nanoscale circuits and their design issues, bridging the existing gap between nanodevice research and nanosystem design.
In response to the growing importance of power system security and reliability, "Transmission Grid Security" proposes a systematic and probabilistic approach for transmission grid security analysis. The analysis presented uses probabilistic safety assessment (PSA) and takes into account the power system dynamics after severe faults. In the method shown in this book the power system states (stable, not stable, system breakdown, etc.) are connected with the substation reliability model. In this way it is possible to: estimate the system-wide consequences of grid faults; identify a chain of events that might lead to blackout; and rank the importance of different substation components at the system level. "Transmission Grid Security" also presents the main features and basic mathematics of PSA. It provides the reader with up-to-date knowledge of the regulatory issues affecting the security of transmission grids in Europe. "Transmission Grid Security" gives a practical method for the security analysis of transmission grids, making it a valuable text for engineers and system operators, as well as postgraduate students. It includes basic information and detailed modules for creating a reliability model that takes into account all the basic operations and components needed after grid faults.
