Abstract
A method and an arrangement for a forecast of wind-resources of a wind-farm are provided. The forecast is done by a numerical weather-prediction-tool, the weather-prediction-tool using a long-term data-set of meteorological data. The data are related to the location of the wind-farm. A wind-speed measurement is done by a wind-turbine of the wind-farm to do a parameterization of an atmospheric turbulence. The wind-speed measurement is used to generate a data-stream, which is combined with the data-set of the meteorological data to do the forecast.
Claims18
A method of determining a forecast of wind-resources of a wind-farm, comprising:
- receiving a long-term data-set of meteorological data which are related to a location of the wind-farm;
- generating a short term data-stream having multiple dimensions by measuring wind-speeds a at a plurality of spatially distributed wind-turbines of the wind-farm and at a plurality of heights for each wind-turbine for a parameterization of an atmospheric turbulence;
- and
- generating a forecast via a numerical weather-prediction-tool by combining the data-stream with the data-set of the meteorological data in order to determine the forecast.
An arrangement for determining a forecast of wind-resources of a wind-farm having a plurality of wind turbines, comprising:
- a numerical weather-prediction-tool for determining the forecast, the weather-prediction-tool using a long-term data-set of meteorological data which are related to a location of the wind-farm;
- a measuring tool for measuring wind-speeds for a parameterization of an atmospheric turbulence, the measuring tool being arranged at a plurality of spatially distributed wind-turbines and at a plurality of heights for each wind-turbine to generate a short term data-stream having multiple dimensions;
- and
- a computer-system for modeling a numerical weather prediction using the short term data-stream and the long-term data-set of meteorological data.
