Plug-in electric and hybrid vehicles (PEVs) have the potential to provide substantial storage to a city's grid, a key component in mitigating intermittency issues of power sources. But the batteries of these vehicles also need to be charged at times when their users need them. Thus, V2G (vehicle-to-grid) is becoming an important issue in the future grid. An integrated treatment of this system, from power generation, monitoring, storage in stationary and PEV batteries to control is a complex task. This book explores the connection between the stationary grid and PEV power storage. Topics covered include: the impact of PEVs and V2G on smart grid and renewable energy systems; distributed energy resource with PEV battery energy storage in the smart grid; power conversion technology in smart grid and PEVs; power control and monitoring of smart grid with PEVs; PEV charging technologies and V2G on distributed energy resources and utility interfaces; economic, social and environmental dimensions of PEVs in the smart grid. This book will be of interest to researchers and advanced students in electric vehicles and smart grid technologies, and policy-makers and planners developing smart grid infrastructure and sustainable transport initiatives.

To ensure stable operation of a power system, it is necessary to analyse the power system performance under various operating conditions. Analysis includes studies such as power flow and both steady-state and transient stability. To perform such studies requires knowledge about the models used to represent the various components that constitute an integrated power system. In situations where there is a risk of loss of stability, it is necessary to apply controls that can ensure stable and uninterrupted supply of electricity following a disturbance. The subject of stability thus encompasses modelling, computation of load flow in the transmission grid, stability analysis under both steady-state and disturbed conditions, and appropriate controls to enhance stability. All these topics are covered in this book, providing a comprehensive treatment of the overall subject of stability of power systems. Topics covered include modelling of the synchronous machine; the synchronous machine connected to power systems; modelling of transformers, transmission lines and loads; power flow analysis; optimal power flow; small signal stability; transient stability; transient energy function methods; artificial intelligent techniques; power system stabilizers; series compensation; shunt compensation; compensation devices; and recent technologies. The subject matter is covered at a level that is suitable for students, scientists and engineers involved in the study, design, analysis and control of power systems.
This book provides a compact yet comprehensive treatment of advanced data-driven signal processing techniques for the analysis and characterization of both ambient power system data and transient oscillations resulting from major disturbances. Inspired by recent developments in multi-sensor data fusion, multi-temporal data assimilation techniques for power system monitoring are proposed and tested in the context of modern wide-area monitoring system architectures. Recent advances in understanding and modeling nonlinear, time-varying power system processes are reviewed and factors affecting the performance these techniques are discussed. A number of algorithms and examples are presented throughout the text as an aid to understanding the basic material provided. Challenges involved in realistic monitoring, visualization and analysis of actual disturbance events are emphasized and examples of applications to a wide range of power networks are provided. Topics covered include: wide-area monitoring and analysis systems; wide-area monitoring system architectures; spatio-temporal modeling of power system dynamic processes; advanced data processing and feature extraction; multi-sensor multitemporal data fusion; monitoring the status of the system; near real-time analysis and monitoring; and interpretation and visualization of wide-area PMU measurements. This book will be of interest to students, researchers and engineers involved in the study, design, analysis and control of power systems.
This comprehensive book covers the state-of-the-art in control-oriented modelling and identification techniques. With contributions from leading researchers in the subject, Control-oriented Modelling and Identification: Theory and practice covers the main methods and tools available to develop advanced mathematical models suitable for control system design, including: object-oriented modelling and simulation; projection-based model reduction techniques; integrated modelling and parameter estimation; identification for robust control of complex systems; subspace-based multi-step predictors for predictive control; closed-loop subspace predictive control; structured nonlinear system identification; and linear fractional LPV model identification from local experiments using an H1-based glocal approach. This book also takes a practical look at a variety of applications of advanced modelling and identification techniques covering spacecraft dynamics, vibration control, rotorcrafts, models of anaerobic digestion, a brake-by-wire racing motorcycle actuator, and robotic arms.
This book describes the three major power system transients and dynamics simulation tools based on a circuit-theory approach that are widely used all over the world (EMTP-ATP, EMTP-RV and EMTDC/PSCAD), together with other powerful simulation tools such as XTAP. In the first part of the book, the basics of circuit-theory based simulation tools and of numerical electromagnetic analysis methods are explained, various simulation tools are introduced and the features, strengths and weaknesses are described together with some application examples. In the second part, various transient and dynamic phenomena in power systems are investigated and studied by applying the numerical analysis tools, including: transients in various components related to a renewable system; surges on wind farm and collection systems; protective devices such as fault locators and high-speed switchgear; overvoltages in a power system; dynamic phenomena in FACTS, especially STATCOM (Static Synchronous Compensator); the application of SVC to a cable system; and grounding systems. Combining underlying theory with real-world examples, this book will be of use to researchers involved in analysis of power systems for development and optimization, and professionals and advanced students working with power systems in general

This updated edition of the industry's classic text combines the theory, practice, and latest technology of spectrum and network measurements in electronic systems to offer a comprehensive and easy way to understand frequency domain measurements. Spectrum and Network Measurements, 2nd Edition has been completely updated to take into account the latest technology, particularly focusing on the shift from analog to digital in communication systems, plus an important new chapter on EMC measurements of radiated and conducted emissions has also been added. Using simplified block diagrams, this book offers a thorough coverage of critical concepts, such as decibels, Fourier analysis, noise effects, impedance matching, intermodulation distortion, reflection measurements, and S-Parameters. By picking up where the majority of electrical engineering programs stop, this title takes basic EE theory and translates it to the world of electronic measurements. This enables the reader to understand the basic theory of signals and systems, relate it to measured results, and apply it when creating new designs.
