August 5, 2010 —" From Trades to Turbines: The Art and Science of Wind Energy Resource Assessment  ."

During the past 20 years, the Risø-DTU National Laboratory for Sustainable Energy has been one of the world's leading institutions for wind resource assessment. Using a combination of measurements and fast-flow modeling, they developed the European Wind Atlas in 1989. As a result of this project, the "WAsP" method also was developed and is now used in nearly 90% of the wind farms built today. The WAsP wind resource method allows high-resolution data to be incorporated into the wind resources assessment. In 2001, through the use of meso-scale models combined with the WAsP method, Risø-DTU also developed the Numerical Wind Atlas method (KAMM/WAsP method). During this presentation, Hans Jørgensen, of Risø-DTU , talked about the method used to calculate the annual resource with the option to cover monthly resources as well. In addition to the KAMM/WASP method, Jørgensen's group has developed a dynamic method that includes the daily variation. These methods have been applied in various regions around the world and Jørgensen gave an introduction to the different methods developed at Risø-DTU. He included examples and verification from the Egyptian, Chinese, South African, Indian, and Danish wind atlas.
