A novel wind speed prediction strategy based on Bi-LSTM, MOOFADA and transfer learning for centralized control centers

摘要

With the rapid development of wind power generation, a centralized monitoring center for wind farms has emerged to save investment and reduce operating costs. However, it is a daunting challenge for the intelligent wind speed prediction system of centralized control center to realize the wind speed prediction of wind farms in different environments. To this end, this paper proposes a multi-wind farm wind speed prediction strategy suitable for wind farm centralized control center. Firstly, the Bi-LSTM deep learning model is pre-trained with the historical data of four wind farms in typical geographical locations to obtain four intelligent wind speed prediction models with different characteristic parameters. Then, transfer learning is used to transfer the four pre-trained models to the wind farm centralized control center, and the wind speed of any wind farm can be predicted using these four Bi-LSTM models. Finally, the MOOFADA optimization algorithm is used to weight the four sets of prediction results to obtain the optimal wind speed prediction results. Experiments and comparisons with a variety of algorithms show that this algorithm is far higher in prediction accuracy than other algorithms, and has strong adaptability, which can be widely used in wind speed prediction for wind farms.(c) 2021 Elsevier Ltd.
