Die rationelle Energieverwendung im Bereich wärmetechnischer Systeme hat im mittel europäischen Raum einen hohen Stellenwert, da bei der überwiegenden Anzahl der Haus halte und Gewerbebetriebe der Energieverbrauch zur Wärmeerzeugung den größten An teil am Gesamtenergieverbrauch hat. Das Ziel des vorliegenden Bandes ist es, dem Leser die Vorgehensweise 'zur Beurteilung wärmetechnischer Systeme und energiesparender Maßnahmen zu vermitteln. Schwerpunktmäßig werden die Heiz- und Raumlufttechnik im Umfeld des Menschen behandelt, während das Gebiet der Prozeßwärme für die indu strielle Anwendung aus Gründen des Umfanges nur ansatzweise erörtert werden konnte. Der Anspruch dieses Buches liegt auf einer Ebene, welche bewußt nicht die Einzellösung hervorhebt, da sich das Optimum eines Gesamtsystems noch längst nicht einstellen muß, wenn die Teilsysteme optimiert sind. Das Verständnis der Verzahntheit des vorliegenden Gebietes mit anderen Fachgebieten ist deshalb eine wesentliche Voraussetzung für ko ordinierte Maßnahmen zur rationellen Energieverwendung. Diesem Umstand wird durch zahlreiche qualitative Systembetrachtungen und Zahlenbeispiele Rechnung getragen. Im ersten Abschnitt werden die speziellen Grundlagen der Heiz- und Raumlufttechnik be handelt. Dazu zählen Kenntnisse über technische Funktionsabläufe und die Behaglich keitsanforderungen des Menschen, zu deren Aufrechterhaltung diese Anlagen gebaut werden. Anlagentechnische Maßnahmen zur Energieeinsparung müssen sich immer an der Erfüllung der Behaglichkeitsanforderungen messen lassen. Weiterhin gehört es auch zu einer wirkungsvollen Energieberatung, Maßnahmen an gebäudetechnischen Anlagen als Teilmaßnahme am Gesamtsystem Gebäude zu verstehen, weil durch den Umfang der Systemverbesserung (energetisch-ökonomisch) letztlich die Rangfolge der durchzuführen den Maßnahmen bestimmt wird.

While most books approach power electronics and renewable energy as two separate subjects, Power Electronics for Renewable and Distributed Energy Systems takes an integrative approach; discussing power electronic converters topologies, controls and integration that are specific to the renewable and distributed energy system applications. An overview of power electronic technologies is followed by the introduction of various renewable and distributed energy resources that includes photovoltaics, wind, small hydroelectric, fuel cells, microturbines and variable speed generation. Energy storage systems such as battery and fast response storage systems are discussed along with application-specific examples. After setting forth the fundamentals, the chapters focus on more complex topics such as modular power electronics, microgrids and smart grids for integrating renewable and distributed energy. Emerging topics such as advanced electric vehicles and distributed control paradigm for power system control are discussed in the last two chapters. With contributions from subject matter experts, the diagrams and detailed examples provided in each chapter make Power Electronics for Renewable and Distributed Energy Systems a sourcebook for electrical engineers and consultants working to deploy various renewable and distributed energy systems and can serve as a comprehensive guide for the upper-level undergraduates and graduate students across the globe.

The search for clean, renewable energy sources has yielded enormous growth and new developments in these technologies in a few short years, driving down costs and encouraging utilities in many nations, both developed and developing, to add and expand wind and solar power capacity. The first, best-selling edition of Wind and Solar Power Systems provided the most complete and modern treatment of renewable energy. This second edition continues the tradition by offering updated and expanded coverage of this growing field. The book begins with individual sections devoted to wind power and solar photovoltaic technologies, their engineering fundamentals, conversion characteristics, operational considerations to maximize output, and emerging trends. The discussion of wind power includes the theory of induction machine performance and operation as well as generator speed control, while the solar PV section includes array design, environmental variables, and sun-tracking methods. This edition includes two chapters devoted to new and specialized technologies. The third section explores large-scale energy storage technologies, overall electrical system performance, and total plant economy while the final section explores ancillary power systems derived from the sun. Focusing on the complete system rather than on a single component, Wind and Solar Power Systems: Design, Analysis, and Operation, Second Edition offers the most comprehensive reference to all aspects of modern renewable energy systems.

A clear explanation of the technology for producing and delivering electricity Electric Power Systems explains and illustrates how the electric grid works in a clear, straightforward style that makes highly technical material accessible. It begins with a thorough discussion of the underlying physical concepts of electricity, circuits, and complex power that serves as a foundation for more advanced material. Readers are then introduced to the main components of electric power systems, including generators, motors and other appliances, and transmission and distribution equipment such as power lines, transformers, and circuit breakers. The author explains how a whole power system is managed and coordinated, analyzed mathematically, and kept stable and reliable. Recognizing the economic and environmental implications of electric energy production and public concern over disruptions of service, this book exposes the challenges of producing and delivering electricity to help inform public policy decisions. Its discussions of complex concepts such as reactive power balance, load flow, and stability analysis, for example, offer deep insight into the complexity of electric grid operation and demonstrate how and why physics constrains economics and politics. Although this survival guide includes mathematical equations and formulas, it discusses their meaning in plain English and does not assume any prior familiarity with particular notations or technical jargon. Additional features include: * A glossary of symbols, units, abbreviations, and acronyms * Illustrations that help readers visualize processes and better understand complex concepts * Detailed analysis of a case study, including a Web reference to the case, enabling readers to test the consequences of manipulating various parameters With its clear discussion of how electric grids work, Electric Power Systems is appropriate for a broad readership of professionals, undergraduate and graduate students, government agency managers, environmental advocates, and consumers.

Reflecting its reliance on fossil fuels, the electric power industry produces the majority of the world's greenhouse gas emissions. The need for a revolution in the industry becomes further apparent given that 'decarbonization' means an increasing electrification of other sectors of the economyin particular, through a switch from gasoline to electric vehicles. Of the options for producing electric power without significant greenhouse gas emissions, renewable energy is most attractive to policymakers, as it promises increased national self-reliance on energy supplies and the creation of new industries and jobs, without the safety and political concerns of nuclear power or the unproven technology of carbon capture and storage. Drawing on both economic theory and the experiences of the United States and EU member states, Harnessing Renewable Energy addresses the key questions surrounding renewable energy policies. How appropriate is the focus on renewable power as a primary tool for reducing greenhouse gas emissions? If renewable energy is given specific support, what form should that support take? What are the implications for power markets if renewable generation is widely adopted? Thorough and well-evidenced, this book will be of interest to a broad range of policymakers, the electric power industry, and economists who study energy and environmental issues.
