Abstract

Cold pools (CPs) are localized regions of cold, dense air formed beneath convective rainstorms, producing sharp temperature drops and wind surges near the surface that propagate outward as gust fronts. While CPs have been extensively studied in other regions, their occurrence and influence on wind energy in Denmark remain understudied. This work presents a new analysis of CP events detected at the DTU Test Centre, on the West Coast of Denmark, between 2016-2024 using high-frequency meteorological mast data. A validated detection algorithm identified 134 events, which were characterized in terms of intensity, duration, and turbulence properties. Composite anomalies revealed typical wind surges of 5 m/s and directional shifts of 30 degrees at hub height. To assess their operational relevance, these anomalies were integrated into wind farm simulations using DTU's dynamic wind system simulator, Dynamiks, coupled with the Dynamic Wake Meandering (DWM) model. The results show that CP passages can drive rapid increases in wind farm output, depending on inflow angle, turbulence, and background wind speed. These findings highlight the importance of incorporating convective outflow events into wind resource assessment and operational planning, particularly for markets where short-term variability can create imbalance costs. This study represents the first dedicated investigation of CPs in Denmark and demonstrates their potential significance for the wind energy sector.
