During the last decades, the importance of clean energy resources is being increased. Wind is one of the most significant clean energy resources. Forecasting the output power of wind turbines is important for turbine control to improve power grids’ performance and maintenance. In this study, a novel method for predicting the power of wind turbines is proposed based on integrating data preprocessing, re-sampling, feature selection (genetic algorithm), and outlier detection (Histogram-Based Outlier Score) techniques to prepare the data for the deep learning (DL) algorithms. The results show that, after removing features chosen by the genetic algorithm (GA) method, the mean absolute error (MAE) reduced considerably to 333.7. Integrating Histogram-Based Outlier Score (HBOS) with genetic algorithm (GA) significantly decreased the MAE to 488. Comparing the results with benchmark machine learning algorithms, namely Light Gradient Boosting Machine (LGBM), Extreme Gradient Boosting Regression (×GBR), K-Nearest Neighbor (KNN), Support Vector Regression (SVR), and Recurrent Neural Networks (RNN) models, shows a remarkable improvement in the accuracy of turbine power prediction for about 78.7, 944.9, 104.7, 1456.6, and 17.1 in mean absolute error (MAE), respectively.
