The object of this project was to show the existence of high-frequency fluctuations. The measurement of these fluctuations and the subsequent frequency analyses revealed that these frequencies may be
The object was to improve existing PARK models for calculating array losses for wind farms with focus on large offshore wind farms. The project shows that intelligent use of the model parameters
The compiled measuring results and modelling tests produced a scientifically founded basis for providing recommendations for future offshore wind farms in respect of mutual distances between farms and
The project establishes a new model of the Danish electricity system in the form of two buses (east and west Denmark), to which new models of load and production units are connected in the form of
The main points of the project are: 1) Improved methods for modelling of vertical and horizontal variation of wind speeds. 2) Verification, calibration and improvement of acoustic sensors for remote
The object of the research-project is to select which methods will give the best simulation of environmental influence in relation to the geographical placing of the mills, to be able to select what
The project concerns the modelling of aerodynamically generated sound from wind turbines with the aim of predicting and reducing noise emission from wind turbines.
Background: Planning wind farms offshore are generally based on little knowledge of the wind speeds. It is due to the limited amount of offshore meteorological observations worldwide. This again has
The objective of the project was to participate in the IEA annex 'Dynamic models of wind farms for power system studies'. The objective of the IEA annex is to establish an international forum for
The main objective of Annex XVII is to provide wind energy planners and designers, as well as the international wind engineering community in general, with easy access to quality controlled measured
The main objective of the project is to implement controller design of wind turbines in the general design process, on the same level as structural dynamics and aerodynamics. Specific focus is on
Background: Within the Aeroelastic Research Program carried out from 1997 to 2002 by Risø and DTU a coordinated and continuous work has been carried out on the development of advanced computer models
