Wind speed prediction plays a crucial role in renewable energy planning and optimization. This study presents comprehensive analysis of wind forecasting using Random Forest (RF) models. The research utilized high-resolution data collected throughout 2023 at the Bowen Abbot facility. Our methodology employed RF with cross-validation techniques to ensure model stability reliability. demonstrated robust performance across multiple evaluation metrics, achieving an average R² score 0.9155 (±0.0035) through 5-fold cross-validation. Error revealed consistent training, testing, validation sets, root mean square errors (RMSE) 0.6624 (±0.0098) m/s. Feature importance that 3-hour rolling was most influential predictor, accounting for 89.84% model's predictive power, followed by 1-hour (2.59%) (2.57%) lagged speeds. hierarchical temporal features suggests recent patterns are accurate predictions. error distribution showed approximately normal distributions slight deviations tails, particularly set (kurtosis: 5.2146). Key findings indicate maintains high accuracy different scales, absolute (MAE) averaging 0.4998 partitions its reliability operational deployment. These results demonstrate potential algorithms applications, providing valuable tool power generation management. study's contribute growing body on machine learning applications energy, offering insights into methodologies systems.
