The Wind Integration National Dataset (WIND) Toolkit
The WIND Toolkit is a combination of three datasets that reflect the ramping characteristics, spatial and temporal correlations, capacity factors of simulated wind plants, and are time synchronized with available load profiles. The datasets include a meteorological dataset based on mesoscale Numerical Weather Prediction model data, a wind power production dataset based on mesoscale model data, and a power and wind speed forecast dataset. These sets were created using the Weather Research and Forecasting Model run on a 2-km grid over 126,000 locations across the contiguous United States at a five-minute resolution with accuracy mimicked by reforecasting the years 2007–2013 using industry-standard techniques. This combination offers vast improvement to existing wind datasets by significantly expanding the geographic area considered, the number of sites included, and the temporal resolution of the data to aid in subhourly modeling of power system operations. Moreover, the WIND Toolkit's creation also followed the latest wind energy research science and current industry standards.
Ease of use and data accessibility were crucial requirements for the WIND Toolkit. As such, wind power, 100-m wind speed and direction, 2-m temperature, surface air pressure and air density, and capacity factor data for selected sites can be downloaded at http://maps.nrel.gov/wind_prospector. The toolkit employs a graphical user interface, along with an Application Programming Interface (API), that provides access to data using innate search methods. Because of the extensive data and storage size limitations, an extended meteorological dataset at every grid point is stored at the National Renewable Energy Laboratory (NREL).
