First, the actual operation and maintenance data of wind farms are normalized and divided into a training set and a test set. Then, an LSTM structure is designed and a Sub-Grid Search (SGS) algorithm is proposed to optimize the hyperparameters of the LSTM network. Finally, the power data are decomposed and noise-reduced using TEMD is improved by the variable-point technique and the TEMD-LSTM power forecast model is constructed to predict the power in time. The predicted values obtained are restored and evaluated by the original size. The results show that compared with five other algorithms of the same kind, the proposed algorithm in this paper has a root mean square error (RMSE) of 30.40, a trend accuracy (TA) value of 67.23% and a training time of 886 s, with the best overall performance. <\/jats:p>","DOI":"10.1142\/s0218126623500299","type":"journal-article","created":{"date-parts":[[2022,7,28]],"date-time":"2022-07-28T16:00:30Z","timestamp":1659024030000},"source":"Crossref","is-referenced-by-count":1,"title":["An Improved Long Short-Term Memory Neural Network Wind Power Forecast Algorithm Based on TEMD Noise Reduction"],"prefix":"10.1142","volume":"32","author":[{"given":"Hong","family":"You","sequence":"first","affiliation":[{"name":"College of Electrical & Information Engineering, Hunan Institute of Engineering, Xiangtan 411104, P.
