This book will be focused on the modeling and control of the DFIM based wind turbines. In the first part of the book, the mathematical description of different basic dynamic models of the DFIM will be carried out. It will be accompanied by a detailed steady-state analysis of the machine. After that, a more sophisticated model of the machine that considers grid disturbances, such as voltage dips and unbalances will be also studied. The second part of the book surveys the most relevant control strategies used for the DFIM when it operates at the wind energy generation application. The control techniques studied, range from standard solutions used by wind turbine manufacturers, to the last developments oriented to improve the behavior of high power wind turbines, as well as control and hardware based solutions to address different faulty scenarios of the grid. In addition, the standalone DFIM generation system will be also analyzed.

Highlights and examines the growing convergence between the food and agricultural industries—the technological, environmental, and consumer-related drivers of this change, and the potential outcomes This is the first book of its kind to connect food and the food industry with agriculture, water resources, and water management in a detailed and thorough way. It brings together a small community of expert authors to address the future of the food industry, agriculture (both for plants and animals), and water—and its role in a world of increasing demands on resources. The book begins by highlighting the role of agriculture in today's food industry from a historical perspective—showing how it has grown over the years. It goes on to examine water management; new ways of plant breeding not only based on genetic modification pathways; and the attention between major crops (soy, corn, wheat) and so-called «orphan crops» (coffee, cocoa, tropical fruits). The book then turns towards the future of the food industry and analyzes major food trends, the new food, and «enough» food; discusses possible new business models for the future food industry; and analyzes the impact that the «internet of everything» will have on agriculture and the food industry. Finally, Megatrends in Food and Agriculture: Technology, Water Use and Nutrition offers scenarios about how agriculture, food, and the food industry might undergo some radical transformations. Assesses the evolution of food production and how we arrived at today's landscape Focuses on key areas of change, driven by both innovation and challenges such as new technologies, the demand for better nutrition, and the management of dwindling resources Highlights the role of better-informed consumers who demand transparency and accountability from producers Is written by industry insiders and academic experts Megatrends in Food and Agriculture: Technology, Water Use and Nutrition is an important resource for food and agriculture industry professionals, including scientists and technicians as well as decision makers, in management, marketing, sales, and regulatory areas, as well as related NGOs.

Grapes (Vitis spp.) are economically the most important fruit species in the world. Over the last decades many scientific advances have led to understand more deeply key physiological, biochemical, and molecular aspects of grape berry maturation. However, our knowledge on how grapevines respond to environmental stimuli and deal with biotic and abiotic stresses is still fragmented. Thus, this area of research is wide open for new scientific and technological advancements. Particularly, in the context of climate change, viticulture will have to adapt to higher temperatures, light intensity and atmospheric CO2 concentration, while water availability is expected to decrease in many viticultural regions, which poses new challenges to scientists and producers. With Grapevine in a Changing Environment, readers will benefit from a comprehensive and updated coverage on the intricate grapevine defense mechanisms against biotic and abiotic stress and on the new generation techniques that may be ultimately used to implement appropriate strategies aimed at the production and selection of more adapted genotypes. The book also provides valuable references in this research area and original data from several laboratories worldwide. Written by 63 international experts on grapevine ecophysiology, biochemistry and molecular biology, the book is a reference for a wide audience with different backgrounds, from plant physiologists, biochemists and graduate and post-graduate students, to viticulturists and enologists.
