Aspects on remote sensing assisted wind farm minute-scale forecasting

The larger share of non-scheduled renewable energy in the electricity mix is not only subject to forecast uncertainty, but also increases volatility in the electricity markets. The motivation behind the present work is the desire to operate wind farms proactively, and facilitate participation on intra-hour balancing markets which requires precise forecasts with minimal uncertainty. The aim is to contribute to further understanding of the benefit and limitations of using independent site measurements of wind speed to assist forecasts of the available power. Specifically, the study investigates how the time of availability and distance to target location of the observation impacts the skill of the forecast. To achieve this the study has used a 180 m tall mast and 7 AQ510 SODARs placed at varying distances from the met-tower in combination with a 5-member high resolution numerical weather prediction ensemble.
