Datacenter Power Management in Smart Grids (Paperback): Xue Liu, Fanxin Kong Datacenter Power Management in Smart Grids (Paperback)
Xue Liu, Fanxin Kong
R1,863 Discovery Miles 18 630 Ships in 10 - 15 working days

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 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."

R2,582 Discovery Miles 25 820 Out of stock

The purpose of this book is to describe the theory of Digital Power Electronics and its applications. The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distortion. These new parameters result in the definition of new mathematical modeling:
- A zero-order-hold (ZOH) is used to simulate all AC/DC rectifiers.
- A first-order-hold (FOH) is used to simulate all DC/AC inverters.
- A second-order-hold (SOH) is used to simulate all DC/DC converters.
- A first-order-hold (FOH) is used to simulate all AC/AC (AC/DC/AC) converters.
* Presents most up-to-date methods of analysis and control algorithms for developing
power electronic converters and power switching circuits
* Provides an invaluable reference for engineers designing power converters, commercial
power supplies, control systems for motor drives, active filters, etc.
* Presents methods of analysis not available in other books.

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.
