Wind Power Forecasting
WindFor™ (formerly known as WPPT) is a software solution for wind power forecasting. WindFor™ delivers highly accurate predictions of wind energy production for the operational horizon (ranging from a few minutes ahead in time, up to a couple of weeks). WindFor™ is very flexible and has a long track record of producing accurate forecasts in almost any condition. WindFor™ is both applicable on a portfolio scale and country-wide. For more information on the country-wide application of WindFor™, see Total Forecast.

making it the preferred choice for customers all over the world.
How does WINDFOR™ work
WindFor™ is a self-learning and self-calibrating software system based on a combination of physical models and advanced machine learning. This combines the best of artificial intelligence with wind power domain knowledge in order to produce the most accurate wind energy forecasts available.
WindFor™ is initialized using either a power curve from the design of the wind farm or by using historical weather and production data to train the models.
After initialization, forecasts are produced every time the system receives new data which can be either updated weather forecasts or new production data. WindFor™ can run in either online mode and continuously receives real-time production data or in off-line mode where historical data are retrieved monthly or any other time interval. By integrating WindFor™ directly with the SCADA system and thereby providing real-time production data, very accurate short term forecasts can be achieved.
Weather forecasts (incl. ensemble forecasts) are typically supplied as an integrated part of the solution. The system can use one or more weather forecast providers as input and automatically detect the optimal prioritization of the different weather forecasts for each wind farm and for different forecast horizons. Weather data is also made available to the client such that the client can compare energy forecasts and weather inputs.
The self-learning and self-calibrating algorithms will continuously learn about the wind farm characteristics and will adapt to changing conditions, seasonal variations and as the wind turbines ages such that forecasts stay accurate at all times.
By delivering schedules of availability and curtailments, the client can make sure that WindFor™ takes these planned events into consideration. Furthermore, if the client provides real time availability and curtailment information from the wind farm, the data will be used to train models and adjust short term forecasts which significantly increase accuracy.
WindFor™ can deliver energy forecasts in almost any file format and can be integrated directly into the operational IT-platform of the client, such that data are retrieved and delivered seamlessly to and from relevant systems.
WindFor™ is available as a software package installed locally on the client’s servers or as a service hosted on servers operated and maintained by ENFOR.
WindFor™ is supplied with various support, maintenance and license packages, which can be tailor-made to client specifications to provide a cost/performance ratio which fits the needs of the individual client.
