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."

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.

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.

Since the first edition of this book in 1983, HVDC technology has continued to expand and few power systems can now escape its influence.
