Available in PDF, EPUB and Kindle. Book excerpt: A central feature of wireless networks is multiple users sharing a common medium. Cellular systems are among the most common examples of such networks. The main phenomenon resulting from this inter-user interaction is interference, and thus analyzing interference networks is critical to determine the capacity of wireless networks. The capacity region of an interference network is defined as the set of rates that the users can simultaneously achieve while ensuring arbitrarily small probability of decoding error. It is an inherently hard problem to find the capacity region of interference networks. Even the capacity region of a general 2-user interference channel is a prominent open problem in information theory. This work's goal is to derive achievable regions that are improved over known results, and when possible, capacity theorems, for K user interference networks. Another multiuser channel that is commonly found in wireless systems is a broadcast channel. Broadcast channels stand side by side with Interference channels as the two of the most important channels for which capacity results are still not completely known. In this work we develop inner and outer bounds on the capacity region of fading broadcast channels, using which we find a part of the capacity region under some conditions. In summary, this work first presents coding arguments for new achievable rate regions and, where possible, capacity results for K-user interference networks. Second, it provides inner and outer-bounds for a class of fading broadcast channels.

Available in PDF, EPUB and Kindle. Book excerpt: A generic DC grid model that is compatible with the standard AC system stability model is presented and used to analyse the interaction between the DC grid and the host AC systems. A multi-terminal DC (MTDC) grid interconnecting multiple AC systems and offshore energy sources (e.g. wind farms) across the nations and continents would allow effective sharing of intermittent renewable resources and open market operation for secure and cost-effective supply of electricity. However, such DC grids are unprecedented with no operational experience. Despite lots of discussions and specific visions for setting up such MTDC grids particularly in Europe, none has yet been realized in practice due to two major technical barriers: Lack of proper understanding about the interaction between a MTDC grid and the surrounding AC systems. Commercial unavailability of efficient DC side fault current interruption technology for conventional voltage sourced converter systems This book addresses the first issue in details by presenting a comprehensive modeling, analysis and control design framework. Possible methodologies for autonomous power sharing and exchange of frequency support across a MTDC grid and their impact on overall stability is covered. An overview of the state-of-the-art, challenges and on-going research and development initiatives for DC side fault current interruption is also presented.

This book was released on 2019-09-03 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses novel methods for planning and coordinating converters when an existing point-to-point (PtP) HVDC link is expanded into a multi-terminal HVDC (MTDC) system. It demonstrates that expanding an existing PtP HVDC link is the best way to build an MTDC system, and is especially a better option than the build-from-scratch approach in cases where several voltage-sourced converter (VSC) HVDC links are already in operation. The book reports in detail on the approaches used to estimate the new steady-state operation limits of the expanded system and examines the factors influencing them, revealing new operation limits in the process. Further, the book explains how to coordinate the converters to stay within the limits after there has been a disturbance in the system. In closing, it describes the current DC grid control concept, including how to implement it in an MTDC system, and introduces a new DC grid control layer, the primary control interface (IFC).

Available in PDF, EPUB and Kindle. Book excerpt: Electric power systems are headed for a true changing of the guard, due to the urgent need for achieving sustainable energy delivery. Fortunately, the development of new technologies is driving the transition of power systems toward a carbon-free paradigm while maintaining the current standards of quality, efficiency, and resilience. The introduction of HVDC and FACTS in the 20th century, taking advantage of dramatic improvements in power electronics and control, gave rise to unprecedented levels of flexibility and speed of response in comparison with traditional electromechanical devices. This flexibility is nowadays required more than ever in order to solve a puzzle with pieces that do not always fit perfectly. This Special Issue aims to address the role that FACTS and HVDC systems can play in helping electric power systems face the challenges of the near future.

Frederick Carr, Gudrun Funk, Phil Hopkins, Tcat Houser, Ian Kayne, Milan Kosanovic, George P.Lister, James Pyles, Maxim Ratinov, Christine Schmied Any beliefs that the current CompTIA® A+ tests are easy are sadly mistaken. This work started as an update for the two ExamInsight books created by Tcat Houser, et al. The sheer size and page count of this work should be a hot tip that the A+ certification exams 220-301 and 220-302 are many things. The word easy does not fit the A+ Certification Test. Thanks to the Internet and hard working SUBJECT MATTER EXPERTS (SMEs), this work contains vast amounts of data about the A+ Certification Test and getting an A+ Certification online or offline. Think of this title as the missing link for the new A+ certification series. The nature of the new tests requires a new approach. A+ 4 REAL is the new approach. Written in a conversational style you interact with experts from the Pacific Northwest to Europe and beyond. This work was created for A+ Certification Training and the countless people who have done a reconnaissance mission on the Operating System test (220-302), and for those who dont want to follow in that path. The PC user who is trying to understand what is going on under the hood or is looking for some really good tricks and tips. A few chapters are included that are not required for the current A+ tests, and are very helpful in that bigger test called REAL LIFE. Therefore you are encouraged to pay close attention to the discussions on LINUX and MACINTOSH. The light-hearted work from your Safety SME enlightens you on protecting yourself from a fate worse than death. It has taken a great number of person-years to produce A+ 4 REAL. The SMES were given the freedom to write style. The end result is a work you wont want to put down. Features within the 787 pages: Missing Link for Success: Built to be "The Missing Link" for Success with A+ Certification 2003 objectives Hundreds of specific URL's: Approximately 250 live and clickable links will allow in depth research and knowledge building.

Available in PDF, EPUB and Kindle. Book excerpt: Wind power is often held up as the most accessible and cost-effective route to reducing our reliance on fossil fuels and improving our energy independence, yet knowledge of what it offers is often clouded by myths and misunderstandings, which can hamper its adoption. This new book, the result of an ambitious project coordinated by the European Wind Energy Association, aims to present the facts about wind energy. It includes six sections discussing: technology grid integration economics of wind its industry and markets its environmental impacts the scenarios and targets for wind energy. Contributions are drawn from nine leading research bodies across Europe, and the material is global in its scope. It is therefore an essential resource and reference for those whose work or study demands an in-depth examination of the subject, and for anyone who wants detailed, accurate and up-to-date information on this key energy source.
