The book also introduces the readers to important approaches and the comprehensive subtopics like wave dynamics, examination of intricate turbine blades, and power electronics in miniature wind turbine systems.

The book aims at providing valuable information to the readers regarding AC offshore wind farms. It covers vital aspects of offshore wind farm's energy transmission and grid integration infrastructure. However, not all the electric configurations have been evaluated for this purpose. This book presents a representative case which has been comprehensively analyzed. It has been constructed on three general features of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the place. Thus, after a concise account of concepts related to wind power and several subsea cable modeling options, an offshore wind farm has been modeled and its parameters have been defined to use as a case study. Upon this case study, several analyses of key aspects of connection infrastructure have been performed. The primary aspect to be determined was the management of reactive power flowing through the submarine cable. The much unwelcomed harmonic amplifications in offshore wind farms due to resonances and after this, transient over-voltage complications in electric framework have been characterized. Finally, an offshore wind farm connection infrastructure has been presented in order to meet the grid code requirements for a specific system operator, but not as a close solution, as a result of a methodology based on analysis and simulations to define the most appropriate layout depending on the size and location of each offshore wind farm.

A unique electrical engineering approach to alternative sources ofenergy Unlike other books that deal with alternative sources of energyfrom a mechanical point of view, Integration of Alternative Sourcesof Energy takes an electrical engineering perspective. Moreover,the authors examine the full spectrum of alternative and renewableenergy with the goal of developing viable methods of integratingenergy sources and storage efficiently. Readers become thoroughlyconversant with the principles, possibilities, and limits ofalternative and renewable energy. The book begins with a general introduction and then reviewsprinciples of thermodynamics. Next, the authors explore both commonand up-and-coming alternative energy sources, including hydro,wind, solar, photovoltaic, thermosolar, fuel cells, and biomass.Following that are discussions of microturbines and inductiongenerators, as well as a special chapter dedicated to energystorage systems. After setting forth the fundamentals, the authorsfocus on how to integrate the various energy sources for electricalpower production. Discussions related to system operation,maintenance, and management, as well as standards forinterconnection, are also set forth. Throughout the book, diagrams are provided to demonstrate theelectrical operation of all the systems that are presented. Inaddition, extensive use of examples helps readers better grasp howintegration of alternative energy sources can beaccomplished. The final chapter gives readers the opportunity to learn about theHOMER Micropower Optimization Model. This computer model, developedby the National Renewable Energy Laboratory (NREL), assists in thedesign of micropower systems and facilitates comparisons of powergeneration techniques. Readers can download the software from theNREL Web site. This book is a must-read for engineers, consultants, regulators,and environmentalists involved in energy production and delivery,helping them evaluate alternative energy sources and integrate theminto an efficient energy delivery system. It is also a superiortextbook for upper-level undergraduates and graduate students.

As the demand for energy increases, and fossil fuels continue to decrease, Wind Energy: Renewable Energy and the Environment, Second Edition considers the viability of wind as an alternative renewable energy source. This book examines the wind industry from its start in the 1970s until now, and introduces all aspects of wind energy. The phenomenal growth of wind power for utilities is covered along with applications such as wind-diesel, village power, telecommunications, and street lighting.. It covers the characteristics of wind, such as shear, power potential, turbulence, wind resource, wind turbine types, and designs and performance. The text discusses the measurement and siting of individual wind turbines, and considers the development and economic impact of wind farms. What’s New in the Second Edition: Expands the section on distributed wind Adds new sections on global warming, community wind, and storage Illustrates the need for a shift to renewable energy through discussions on energy use and the order of magnitude estimates for the lifetime of fossil fuels Discusses the interconnection of wind turbines to utility grids, regulations on installation and operation, and environmental concerns This book provides material on statistics, installation, types, and energy data, as well as new information, applications, and updates on the wind industry. It serves as a resource for practicing professionals in the wind energy industry, and can be used by undergraduate and graduate students in energy engineering/environmental engineering/wind technology.

Fault Diagnosis and Sustainable Control of Wind Turbines: Robust Data-Driven and Model-Based Strategies discusses the development of reliable and robust fault diagnosis and fault-tolerant (‘sustainable’) control schemes by means of data-driven and model-based approaches. These strategies are able to cope with unknown nonlinear systems and noisy measurements. The book also discusses simpler solutions relying on data-driven and model-based methodologies, which are key when on-line implementations are considered for the proposed schemes. The book targets both professional engineers working in industry and researchers in academic and scientific institutions. In order to improve the safety, reliability and efficiency of wind turbine systems, thus avoiding expensive unplanned maintenance, the accommodation of faults in their early occurrence is fundamental. To highlight the potential of the proposed methods in real applications, hardware–in–the–loop test facilities (representing realistic wind turbine systems) are considered to analyze the digital implementation of the designed solutions. The achieved results show that the developed schemes are able to maintain the desired performances, thus validating their reliability and viability in real-time implementations. Different groups of readers—ranging from industrial engineers wishing to gain insight into the applications' potential of new fault diagnosis and sustainable control methods, to the academic control community looking for new problems to tackle—will find much to learn from this work. Provides wind turbine models with varying complexity, as well as the solutions proposed and developed by the authors Addresses in detail the design, development and realistic implementation of fault diagnosis and fault tolerant control strategies for wind turbine systems Addresses the development of sustainable control solutions that, in general, do not require the introduction of further or redundant measurements Proposes active fault tolerant ('sustainable') solutions that are able to maintain the wind turbine working conditions with gracefully degraded performance before required maintenance can occur Presents full coverage of the diagnosis and fault tolerant control problem, starting from the modeling and identification and finishing with diagnosis and fault tolerant control approaches Provides MATLAB and Simulink codes for the solutions proposed
