Power quality is necessary for electrical systems to operate in their intended manner without any deterioration of performance. This book highlights the new emerging challenges of power quality due to the penetration of large-scale renewable energy generation technologies, the advances in nonlinear loads, the increased electricity demands in the deregulated market, and the recent requirements of smart grids that need better hierarchical design with enhanced quality, improved controllability, higher reliability, and security. Novel research that links the past, present and future of electrical power grids from a power quality perspective is also introduced. Topics include power quality definitions; frequency-domain power theory and metering of harmonic pollution responsibility; active and passive harmonic filters; shunt flexible AC transmission; power quality improvement using series FACTS; distributed generation systems; islanding scenario generation algorithm; decentralised voltage control in smart grids; techno-economic issues of power quality; economic robust programming for energy management systems; and future trends in power quality. Power Quality in Future Electrical Power Systems is a tool for planners, designers, operators and practicing engineers of electrical power systems who are concerned with power network quality, reliability, and security. It is essential reading for postgraduate students, engineers, academics, and researchers who have some background in electrical power systems.

Datacenter Power Management in Smart Grids overviews recent work on managing and minimizing the cost of data centers in the context of smart grids. It starts by reviewing the operation of smart grids and analyzing how power is consumed in datacenters. Then, it presents various cost minimization approaches using techniques from the fields of optimization, algorithmics, and feedback control. In particular, it focuses on approaches that utilize time-of-use pricing and demand response features to cut the datacenter electricity cost. In a cloud computing environment, companies or individuals offload their computing to the cloud, which is supported by the computing infrastructure called datacenters. The operation of these datacenters consumes large amounts of electricity, bringing high costs and negatively impacting the environment. In the mean time, a new kind of electrical grid, the smart grid, is emerging. Smart grids enable two-way communications between the power generators and the power consumers. Smart grid technology brings many salient features to help deliver power efficiently and reliably. While a lot of research has been conducted on both datacenters and smart grids, Datacenter Power Management in Smart Grids takes the novel approach of considering both together and focuses on cost-aware datacenter power management in the presence of smart grids. This work reviews recent developments in this area and explains how a smart grid operates, where power goes in datacenters, and, most importantly, how to reduce the power cost and/or negative environmental impact when operating datacenters.

The goal of this proposed text is to provide a recourse for engineering students interested in the design and operation of solar electric, solar thermal, wind, and other renewable systems. Solar and wind energy systems have flourished throughout the United States in the last few years as the public calls for reduced dependence on foreign oil. Government programs have been established to meet the public demand. Many states have passed legislation that requires electric utilities to include a portfolio of renewable energy sources in their generation mix. The resulting public demand has stimulated the growth of an industry that provides wind and solar systems, and many small businesses have grown to install these systems. Training programs and courses are now ubiquitous as the demand for designers and installer's increases. Almost every educational institution offers renewable energy classes or curriculum. The organization of this book begins with concepts and terminology for power and energy - the basics needed to communicate and understand the subject. Conventional power systems are briefly discussed to understand the concepts used in the integration of renewable power systems. Discussion then moves to the design and installation of a small residential photovoltaic system and wind generator connected to the electric utility grid. With this background, the student is able to begin developing ideas for a class project. The chapters following concepts and background review delve into the details of photovoltaic and wind systems as interconnected or stand-alone designs. Estimating and predicating energy production is presented using industry distribution functions and online programs. Concepts of temperature coefficients, synchronization, power conversion, and system protection are explained and practiced. These concepts are applied to residential and small commercial systems and later extrapolated to large system design. Economic analysis is presented using basic methodologies such as payback and rate of return. The methodology to develop advanced analysis is introduced using spreadsheets. The remainder of the text explores other renewable technologies, energy storage systems, thermal systems, and renewable related topics.

The authors incorporate new tools and material to aid students with design issues and reflect recent trends in the field.

The supply of energy from primary sources is not constant and rarely matches the pattern of demand from consumers. Electricity is also difficult to store in significant quantities. Therefore, secondary storage of energy is essential to increase generation capacity efficiency and to allow more substantial use of renewable energy sources that only provide energy intermittently. Lack of effective storage has often been cited as a major hurdle to substantial introduction of renewable energy sources into the electricity supply network. This 2nd edition, without changing the existing structure of the 1st edition, has expanded chapters that review different types of renewables and considers which of these requires storage. The book also discusses the limitation of renewables usage without storage and considers more substantial possibilities that arise from integrating a combination of different storage devices into a system. This book will appeal to university teachers and students that are specialising in power systems development, renewables and other nonconventional electrical energy sources integration in the existing power systems, its economics and environmental impact. The first part of the book will also appeal to the general public."

Power system engineers associated with high voltage equipment should find the book of value in relation to fault investigations, maintenance requirements, insulation testing and condition monitoring.

This book is a crash course in the fundamental theory, concepts, and terminology of switching power supplies. It is designed to quickly prepare engineers to make key decisions about power supplies for their projects.
Intended for readers who need to quickly understand the key points of switching power supplies, this book covers the 20% of the topic that engineers use, 80% of the time.
Unlike existing switching power supply books that deal strictly with design issues, this book also recognizes the growing importance of "off-the-shelf" commercial switching power supplies, giving readers the background necessary to select the right commercial supply.
This book covers the core essentials of power supply theory and design while keeping mathematics to the absolute minimum necessary. Special attention is given to the selection of appropriate components, such as inductors and transformers, to ensure safe and reliable operation. Engineers, whose main design responsibilities are in other areas, will better understand the strengths and weaknesses of switching power supplies and whether such supplies are appropriate for their projects. They will be able to give more meaningful design requirements and specifications to those who design switching power supplies.
* Discusses both AC line supplies and DC-DC inverters.
* Covers the main switching power supply designs, including flyback, forward conversion, bridge, buch, boost, and boost/buck topologies.
* Design examples include a 220 volt offline switching power supply and a 110 volt uninterruptible supply.

Significant changes over the past decade in computing technology, along with widespread deregulation of electricity industries, have impacted on power plant operations while affording engineers the opportunity to introduce monitoring and plant-wide control schemes that were previously unfeasible. Contributors of world-class excellence are brought together in Thermal Power Plant Simulation and Control to illustrate how current areas of research can be applied to power plant operation, leading to enhanced unit performance, asset management and plant competitiveness through intelligent monitoring and control strategies.

With the expansion of HV DC transmission throughout the world, and the increasing numbers of international interconnections, few power systems can continue to escape the effect of this technology in their planning and operation. The primary subject of this book is the incorporation of AC-DC converters and DC transmission in power system analysis. However, the concepts and methods described are also applicable to the FACTS (flexible AC transmission systems) technology. As well as conventional power flows, faults and stability, the book describes the simulation of power system steady-state waveform distortion and transient behaviour. The modelling of power electronic devices in electromagnetic transient programs is given prominence, as these programs have become the 'workhorse' of power system design. This graduate-level text should be of interest to practising engineers and researchers involved in the solution of modern power system problems. It will also be a useful reference for advanced electrical engine ering students.

This book surveys some of the techniques available to protect low-voltage electrical and electronic equipment and systems from lightning strikes and other power surges. The book examines the basic discharge processes in air and their effects, through transient electromagnetic field generation and interaction with overhead lines and underground cables. Attention is paid to the use of models for lightning protection and the book focuses on protection techniques based on modelled lightning protection zones. This is then logically developed in a major section on the practical components and applications of protective measures and systems, as well as testing techniques. These are placed in the context of current IEC and VDE standards. The book is highly illustrated with a vast number of photographs as well as system diagrams and tabular matter.

Since the first edition of this book in 1983, HVDC technology has continued to expand and few power systems can now escape its influence. This thoroughly revised text develops the coverage in the first edition, describing the variety of reasons justifying the use of DC transmission as well as the basic concepts and techniques involved in the AC-DC and DC-AC conversion processes. It has been fully updated and enlarged to include descriptions of the widening applications of DC, the current state-of-the-art thyristors and other semiconductor devices, and the new developments that continue to make HVDC a competitive technology. The book should be of interest to practising engineers and researchers involved in the power industry. It will also be of assistance to lecturers and students in the power systems and power electronics disciplines.

Power system reliability and security is highly dependent on the practices employed in both the commissioning and maintenance processes. Both must be to a high standard to ensure that equipment does not enter service with latent deficiencies. This demands engineers who understand the necessary management involved as well as the technical processes. There is very little literature currently available on the subject; a situation which this book seeks to redress. The subject matter covers high voltage plant and the associated protection and control systems and, although it is essentially targeted at the practicalities of commissioning and maintenance, it also incorporates the underpinning technical theory and design considerations. It is aimed primarily at those who are at the outset of their career in electrical engineering, but additionally provides a thorough reference for more experienced engineers.

The worldwide growth in demand for electricity has forced the pace of developments in electrical power system design to meet consumer needs for reliable, secure and cheap supplies. Power system protection, as a technology essential to high quality supply, is widely recognised as a specialism of growing and often critical importance, in which power system needs and technological progress have combined to result in rapid developments in policy and practice in recent years. In the United Kingdom, the need for appropriate training in power system protection was recognised in the early 1960s with the launch of a correspondence course from which these books emerged and have since developed designed to meet the needs of protection staff throughout the world. The Electricity Training Association, in response to the important recent developments in the field of protection, have now commissioned an additional volume covering digital technology. The existing three volumes, of which this is the second, have been reviewed by leading authorities within the electricity supply industry and electrical manufacturing companies in the UK and, with the new fourth volume, the new edition gives a comprehensive and up-to-date treatment of the subject, covering theory, analytical and design principles, equipment design and application and protection management.

Research in artificial intelligence has developed many techniques and methodologies that can be either adapted or used directly to solve complex power system problems. A variety of such problems are covered in this book including reactive power control, alarm analysis, fault diagnosis, protection systems and load forecasting. Methods such as knowledge-based (expert) systems, fuzzy logic, neural networks and genetic algorithms are all first introduced and then investigated in terms of their applicability in the power systems field. The book, therefore, serves as both an introduction to the use of artificial intelligence techniques for those from a power systems background and as an overview of the power systems implementation area for those from an artificial intelligence computing or control background. It is structured so that it is suitable for various levels of reader, covering basic principles as well as applications and case studies. The most popular methods and the most fruitful application fields are considered in more detail. The book contains contributions from top international authors and will be an extremely useful text for all those with an interest in the field.

Distribution networks represent a huge capital investment. To make sensible decisions about their investments, electricity utilities need to form clear-cut design policies and adopt the most accurate systemdesign procedures. Customers' expectations of the reliability of supply continue to rise, market pressures on the design engineer are growing stronger, and the increasing use of computers has changed the entire approach to distribution system design. Technical innovations have presented the design engineer with the means to improve system efficiency. Electricity Distribution Network Design was the first book to be entirely devoted to the planning and design of modern distribution systems, as apposed to the more general aspects of transmission and generation. This second edition has updated its treatment of computer-based planning and reliability. It also covers the implications of international standards, network information systems and distribution automation. With comprehensive and up-to-date bibliographies at the end of each chapter, the book will be useful both for students and for practising engineers involved in distribution network design.
