High speed data converters represent one of the most challenging, important and exciting analog and mixed-signal systems. They are ubiquitous in our modern and highly connected world. Understanding and designing this class of converters require proficiency in analog circuit design, digital design, and signal processing. This book covers high speed data converters from the perspective of a leading high speed ADC designer and architect, and with a strong emphasis on high speed Nyquist A/D converters. Topics covered include an introduction to high-speed data conversion; performance metrics; data converter architectures; sampling; comparators; amplifiers; pipelined A/D converters; time-interleaved converters; digitally assisted converters; evolution and trends The book is intended for engineers and students who design, evaluate or use high speed data converters. A basic foundation in circuits, devices and signal processing is required. The book is meant to bridge the gap between analysis and design, theory and practice, circuits and systems. It covers basic analog circuits and digital signal processing algorithms. There is a healthy dose of theoretical analysis in this book, combined with the practical issues and intuitive perspectives.
Advances in Power System Modelling, Control and Stability Analysis captures the variety of new methodologies and technologies that are changing the way modern electric power systems are modelled, simulated and operated. The book is divided into three parts. Part 1 presents research works on power system modelling and includes applications of telegrapher equations, power flow analysis with inclusion of uncertainty, discrete Fourier transformation and stochastic differential equations. Part 2 focuses on power system operation and control and presents insights on optimal power flow, real-time control and state estimation techniques. Finally, Part 3 describes advances in the stability analysis of power systems and covers voltage stability, transient stability, time delays, and limit cycles. A rich mix of theoretical aspects with practical considerations, as well as benchmarks test systems and real-world applications makes this book essential reading for researchers and students in academia and industry in electric power systems modelling and control
Wide area monitoring, protection and control systems (WAMPACs) have been recognized as the most promising enabling technologies to meet challenges of modern electric power transmission systems, where reliability, economics, environmental and other social objectives must be balanced to optimize the grid assets and satisfy growing electrical demand. To this aim WAMPAC requires precise phasor and frequency information, which are acquired by deploying multiple time-synchronized sensors, known as Phasor Measurement Units (PMUs), providing precise synchronized information about voltage and current phasors, frequency and rate-of-change-of-frequency. This book provides an overview of this emerging technology. Topics covered include an introduction to WAMPACs; reliability-based substation monitoring systems placement; system integrity protection scheme based on PMU technology; new methodologies for largescale power system dynamic analysis; a fuzzy-based knowledge discovery paradigm for on-line optimal power flow analysis; and false data injection attacks and countermeasures for wide area measurement system.
Commercial energy storage has moved from the margins to the mainstream as it fosters flexibility in our smarter, increasingly integrated energy systems. Natural gas has been identified by many as the fuel to take us to the no-carbon horizon; where a hydrogen economy waits on development. These two actors are already connected in precursor applications as transitional solutions for hydrogen handling and transportation are sought ahead of a fully established hydrogen infrastructure. This monograph explores some of leading advances in methane and hydrogen storage as well as the interesting link between these two important elements in our evolving energy system mosaic. Topics covered include: hydrogen absorption for storage; power-to-gas for energy system integration and storage; methanation for power-to-gas applications; production of hydrogen from methane decarbonisation into power to gas scenarios; power-to-gas in an ancillary service market; methane in MOFs: where, why and how; thermal management as a key in storing adsorbed natural gas; and gas hydrate potential and development for methane storage.
This book is an introduction to some of the most important properties of electromagnetic waves and their interaction with passive materials and scatterers. The main purpose of the book is to give a theoretical treatment of these scattering phenomena, and to illustrate numerical computations of some canonical scattering problems for different geometries and materials. The scattering theory is also important in the theory of passive antennas, and this book gives several examples on this topic. Topics covered include an introduction to the basic equations used in scattering; the Green functions and dyadics; integral representation of fields; introductory scattering theory; scattering in the time domain; approximations and applications; spherical vector waves; scattering by spherical objects; the null-field approach; and propagation in stratified media. The book is organised along two tracks, which can be studied separately or together. Track 1 material is appropriate for a first reading of the textbook, while Track 2 contains more advanced material suited for the second reading and for reference. Exercises are included for each chapter.
