AI for Wind Energy

Wind energy is inherently variable, making AI forecasting and optimization essential for maximizing value and grid integration.

Wind AI Applications

• Wind forecasting: ML models predict wind speed and direction at hub height 1-72 hours ahead, achieving 90-95% accuracy for day-ahead forecasts
• Turbine control: AI adjusts blade pitch, yaw, and generator torque in real-time to maximize energy capture while reducing loads
• Wake optimization: AI coordinates turbine operations across the farm to minimize wake effects (one turbine’s wake reduces output of downstream turbines by 10-20%)
• Predictive maintenance: Vibration, temperature, and SCADA data analysis predicts gearbox, bearing, and blade failures
• Curtailment optimization: AI minimizes energy losses from grid curtailment by predicting and pre-adjusting output
