This addition to the ISOR series addresses the analytics of the operations of electric energy systems with increasing penetration of stochastic renewable production facilities, such as wind- and solar-based generation units. As stochastic renewable production units become ubiquitous throughout electric energy systems, an increasing level of flexible backup provided by non-stochastic units and other system agents is needed if supply security and quality are to be maintained. Within the context above, this book provides up-to-date analytical tools to address challenging operational problems such as: * The modeling and forecasting of stochastic renewable power production. * The characterization of the impact of renewable production on market outcomes. * The clearing of electricity markets with high penetration of stochastic renewable units. * The development of mechanisms to counteract the variability and unpredictability of stochastic renewable units so that supply security is not at risk. * The trading of the electric energy produced by stochastic renewable producers. * The association of a number of electricity production facilities, stochastic and others, to increase their competitive edge in the electricity market. * The development of procedures to enable demand response and to facilitate the integration of stochastic renewable units. This book is written in a modular and tutorial manner and includes many illustrative examples to facilitate its comprehension. It is intended for advanced undergraduate and graduate students in the fields of electric energy systems, applied mathematics and economics. Practitioners in the electric energy sector will benefit as well from the concepts and techniques explained in this book.

This book presents a wide range of optimization methods and their applications to various electrical power system problems such as economical load dispatch, demand supply management in microgrids, levelized energy pricing, load frequency control and congestion management, and reactive power management in radial distribution systems. Problems related to electrical power systems are often highly complex due to the massive dimensions, nonlinearity, non-convexity and discontinuity associated with objective functions. These systems also have a large number of equality and inequality constraints, which give rise to optimization problems that are difficult to solve using classical numerical methods. In this regard, nature inspired optimization algorithms offer an effective alternative, due to their ease of use, population-based parallel search mechanism, non-dependence on the nature of the problem, and ability to accommodate non-differentiable, non-convex problems. The analytical model of nature inspired techniques mimics the natural behaviors and intelligence of life forms. These techniques are mainly based on evolution, swarm intelligence, ecology, human intelligence and physical science.

Sooner or later, power system protection is going to cost money. How much is entirely up to you. Setting up a safe and effective AC power system from the very beginning can help avoid costly downtime and repairs, provide backup power during system outages, and minimize workplace accidents. For the past 15 years, Jerry Whitaker's AC Power Systems Handbook has supplied industry professionals with a comprehensive, practical guide to the key elements of AC power for commercial and industrial systems. This third edition is thoroughly revised and completely reorganized to reflect the changing demands of modern power systems. To ease navigation, many sections are now presented as separate chapters filled with updated and expanded information. Most notably, the author adds heavily in the areas of transient suppression hardware, electrical system components, and power system fundamentals. Following a logical progression, coverage flows from power system operation to protecting equipment loads, selecting the right level of protection, grounding, standby power, and safety. Along the way, the author paints a clear picture of the sources of disturbances, the tradeoffs involved for different options, and the advantages and limitations of various approaches. Streamlined to be a hands-on, user-oriented guide, the AC Power Systems Handbook offers expert guidance on designing and installing a safe and efficient power system.

This books focuses on recent break-throughs in the development of a variety of photonic devices, serving distances ranging from mm to many km, together with their electronic counter-parts, e.g. the drivers for lasers, the amplifiers following the detectors and most important, the relevant advanced VLSI circuits. It explains that as a consequence of the increasing dominance of optical interconnects for high performance workstation clusters and supercomputers their complete design has to be revised. This book thus covers for the first time the whole variety of interdependent subjects contributing to green photonics and electronics, serving communication and energy harvesting. Alternative approaches to generate electric power using organic photovoltaic solar cells, inexpensive and again energy efficient in production are summarized. In 2015, the use of the internet consumed 5-6% of the raw electricity production in developed countries. Power consumption increases rapidly and without some transformational change will use, by the middle of the next decade at the latest, the entire electricity production. This apocalyptic outlook led to a redirection of the focus of data center and HPC developers from just increasing bit rates and capacities to energy efficiency. The high speed interconnects are all based on photonic devices. These must and can be energy efficient but they operate in an electronic environment and therefore have to be considered in a wide scope that also requires low energy electronic devices, sophisticated circuit designs and clever architectures. The development of the next generation of high performance exaFLOP computers suffers from the same problem: Their energy consumption based on present device generations is essentially prohibitive.

On August 6 and August 9, 1945, the world became aware of the destructiveness of nuclear energy when the U.S. Army Air Corps dropped atomic bombs on Hiroshima and Nagasaki. Even before the bombs were detonated, though, President Harry Truman had directed his thoughts toward non-military uses of the atom, recognizing that the atomic bomb had given man a new understanding of the forces of nature. This book examines the history and development of nuclear power from the perspective of the U.S. Army's nuclear power program, telling its story from the creation of the Office of Research and Development through the program's days of growth,and on to its eventual decline. This history examines the development of the United States Army's nuclear power program from its inception, through the development and operation of six small nuclear power plants throughout the Western Hemisphere, to its evolution into a military support agency. The Manhattan Project District Engineer, General Kenneth Nichols, who generated the idea for the program, worked for the development of atomic energy for peaceful purposes. From the initial plans to develop nuclear power plants at remote bases, the book traces the path the Army took in getting its proposals approved by the Atomic Energy Commission, formally organizing the nuclear program, and building a prototype of a nuclear power plant. Separate chapters are devoted to Fort Greely, the nuclear program at the height of its success and accomplishment, and its subsequent decline and transitional period. With its list of suggestions for further reading and a comprehensive index, this volume will be a valuable resource for courses in military history, energy issues, and the development of atomic power. It will also represent an important addition to college, university, and public libraries.
