Wind power prediction of CNN-LSTM network model based on unsupervised algorithm processing

Abstract

Wind power prediction is of great significance to the safe and stable operation of power systems and the optimal allocation of energy. Aiming at the huge amount of related data in wind power prediction, a wind power prediction model based on unsupervised algorithm-CNN-LSTM is proposed. Firstly, an unsupervised algorithm is used to preprocess wind power-related data, which solves the problems of large redundancy and slow convergence of training data in traditional forecasting model; therefore the algorithm can be applied to multi-dimensional and large-scale data; then, convolution cyclic neural network model uses convolution neural network to perform multi-layer convolution , and pool stacking calculation on wind power, wind speed, wind direction and other data to extract the characteristic map of wind power data, and takes the characteristic map information as the input information of long-term and short-term memory neural network. Finally, an example is to verify the proposed method.
