基于EWT-CNN-BiGRU的多特征电力负荷预测模型
摘要
Abstract
In order to solve the problem of insufficient accuracy of multi-feature forecasting models in short-term power load data,a convolutional neural network(CNN)fusion bi-directional gated cycle unit(BiGRU)forecasting model based on empirical wavelet transform(EWT)is proposed.Firstly,strong correlation features are extracted from multi-dimensional time series data,and then the selected features are transformed by empirical wavelet transform,and the time series data are mapped to the frequency domain to obtain sub-sequences.the prediction of power load data is realized by convolution neural network and bi-directional gated cycle unit fusion model.The prediction model is verified by experiments using the time series data of a combined cycle power plant in Germany.The results show that the prediction model has a goodness of fit of 99.463%and has a good prediction effect.关键词
