基于VMD的CNN-BiLSTM-Att的短期负荷预测
Short-Term Load Prediction of CNN-BiLSTM-Att Based on VMD
摘要
Abstract
In order to improve the accuracy of short-term power load prediction,a CNN-BiLSTM-Att(Convolutional Neural Network-Bidirectional Long Short-Term Memory-Attention)short-term load prediction model based on variational mode decomposition VMD(Variational Mode Decomposition)is proposed.In this model,the historical load data is decomposed into multiple sub-sequence loads using VMD and combined with weather,date,type of working day and other factors as input characteristics.The predicted value of each sub-sequence load is predicted by this model,and then added and reconstructed to form the actual load prediction curve.By comparison with other models,the VMD-CNN-BiLSTM-Att model has a decrease in the test set.In the continuous weekly load prediction,the average absolute percentage error of daily load prediction is basically maintained between 1%~2%.In the non-working days with complex load changes,the mean absolute percentage error is reduced by 0.13%compared with the CNN-LSTM model.It is proved that VMD-CNN-BiLSTM-Att short-term load forecasting model can improve the accuracy of power load forecasting.关键词
