Lateral tower vibrations of offshore wind turbines are normally lightly damped, and large amplitude vibrations induced by wind and wave loads in this direction may significantly shorten the fatigue life of the tower. This paper proposes the modeling and control of lateral tower vibrations in...

Electric energy security is essential, yet the high cost and limited sources of fossil fuels, in addition to the need to reduce greenhouse gasses emission, have made renewable resources attractive in world energy-based economies. The potential for renewable energy resources is enormous because...

At the moment, the control ability of wind farms is a prime research concern for the grid integration of large wind farms, due to their required active role in the power system. This paper describes the on-going work of a research project, whose overall objective is to analyse and assess the...

Die vorliegenden Arbeit möchte westliche Wirtschaftstheorien und ökonometrische Methoden unter Berücksichtigung der chinesischen Besonderheiten auf die Untersuchungen der nationalen Pkw-Nachfrage in China anwenden und damit den Absatzmarkt analysieren sowie eine Grundlage zur Prognose...
