GASP provides global coverage of the following parameters at a spatial resolution of 250 m, at three heights 50 m, 100 m and 150 m: 50-year wind, turbulence intensity, shear exponent, air density, flow inclination, uncertainty classification and turbine classes
When evaluating the financial feasibility of a wind farm project, it is critical to identify suitable turbine design class to harvest most energy and avoid placing turbines in a dangerous wind environment. Such data were seldom available.
As wind turbines are becoming a more and more integrated part of our energy system, it is necessary to look into the issue, and thus DTU Wind Energy and EMD International joined forces in 2019 creating the project: Global Atlas for Siting Parameters (GASP), funded by EUDP.
Senior Researcher at DTU Wind Energy, Xiaoli Guo Larsén has led the project. She says:
“With the project, we provide global coverage of the following parameters at a spatial resolution of 250 m, at three heights 50 m, 100 m and 150 m: 50-year wind, turbulence intensity, shear exponent, air density, flow inclination, uncertainty classification and turbine classes,” she says and continues:
“Extreme winds and turbulence statistics are also needed to determine what types of turbines will be able to withstand the site-specific wind loads, which is based on IEC standards.”
Not fully there yet
With GASP in function, it is easier for energy planners and manufacturers from all over the world to design the wind farm and better choose the correct turbine classes, which will help avoiding damage and downtime caused by the choice of wrong turbines.
Even though, we have come a long way, we are not completely there yet, says Xiaoli Guo Larsén.
Therefore, DTU Wind Energy and DHI got together and created the Global Atlas for Siting Parameters to enhance Ocean and Coast (GASPOC).
“GASPOC will shorten the project development period for offshore wind farms getting new green energy plants faster into the energy mix,” she explains. In other words, GASPOC will get more sustainable energy out to consumers faster.
GASPOC is also funded by EUDP and will run for three years. DHI is the main lead of this project.
