How can non-windy places make use of wind power for electricity generation? Advanced Wind Turbines provides detailed information that is of great practical importance to wind turbine practitioners from small and congested city-states, where the lack of vast land and high wind speed render the conventional wind turbine less effective. It introduces the non-conventional Darrieus and Savonius wind turbines, as well as their hybrid version, covering basic concepts, computational modelling and recent advances in experimental optimization.What about those who prefer wind turbines in faraway oceans to take advantage of high wind speed, or who come from countries with a lack of shallow seabed? Floating offshore wind turbines are also discussed, and the dynamics of floating vis-à-vis grounded wind turbines are thoroughly expounded upon to aid practitioners in achieving more accurate performance modelling. This is a work of paramount usefulness for areas which have long wanted to jump on the renewable energy bandwagon, but have thus far been hampered by their natural geographical limitations.

Die Anforderung des § 18a Abs. 1 S. 1 LuftVG stellt eine der größten Hürden für den Ausbau der Windenergie an Land dar. Die Norm untersagt die Errichtung von Bauwerken, wenn dadurch Flugsicherungseinrichtungen gestört werden können. Am häufigsten sind Windenergieanlagen im Umfeld sogenannter Drehfunkfeuer betroffen. Seit Jahren diskutieren Wissenschaft und Praxis darüber, wie die Norm zu interpretieren ist und wie sich mögliche Störungen prognostizieren und bewerten lassen. Teilweise wird die Meinung vertreten, die Wissenschaft sei sich in vielen Punkten nicht einig und die Bewertungsmethodik der Deutschen Flugsicherung GmbH (DFS) sei vertretbar. Das Bundesverwaltungsgericht hat die Methodik der DFS unter der Bedingung bestätigt, dass die ihr zugrunde liegenden Annahmen durch wissenschaftliche Gegenpositionen nicht substanziell in Frage gestellt werden. Neven Josipovic klärt, in welchen Punkten sich ein wissenschaftlicher Konsens erkennen lässt und ob die Argumentation der DFS vor dem Hintergrund noch vertretbar ist.

This book provides the fundamental concepts required for the development of an efficient small-scale wind turbine. For centuries, engineers and scientists have used wind turbines of all shapes and sizes to harvest wind energy. Large-scale wind turbines have been successful at producing great amounts of power when deployed in sites with vast, open space, such as in fi elds or in offshore waters. For environments with limited space, such as dense urban environments, small-scale wind turbines are an attractive alternative for taking advantage of the ubiquity of wind. However, many of today's tools for aerodynamic design and analysis were originally developed for large-scale turbines and do not scale down to these smaller devices. Arranged in a systematic and comprehensive manner, complete with supporting examples, Wind Energy Harvesting: Micro- To Small-Scale Turbines is a useful reference for undergraduate and graduate level classes on energy harvesting, sustainable energy, and fl uid dynamics, and an introduction to the field for non-technical readers.

Renewable energy, such as sunlight, wind, rain, tides, waves, and geothermal heat, is the type of energy that can naturally replenish on a human timescale. Renewable energy can replace conventional fossil fuels in several distinct areas and can eliminate the need for fossil fuels. This book presents current research on the developments, potential and challenges of wind energy. The first chapter provides research on potential wind sites, the impacts of wind installation, and thermo economic modeling. The following chapter makes a comparative study of the dynamic behavior of an aero-generator with a double fed induction generator (DFIG) connected to the grid through two controller techniques: SMC and PI Controller. Chapter three discusses the policy and promotion strategy of wind energy developments between Taiwan and Japan. Chapter four looks at the current status of wind power in South Africa, prospects for growth in integrating wind energy in the South African grid and discusses possible challenges that may arise due to high penetration of wind power and outline some possible solutions. The last chapter provides an inventory of challenges for the deployment of wind energy in a 2030 timeframe in the EU.
