Short Term Load Forecasting Based on VMD-DNN

Short-term load forecasting; variational mode decomposition; deep neural networks; empirical mode decomposition

Improving the accuracy of load forecasting is of great significance to economic dispatch and stable operation of power system. A short-term load forecasting model based on variational mode decomposition (VMD) and deep neural network (DNN) is proposed. VMD algorithm is used to decompose load series into different intrinsic mode functions (IMF), and each IMF is combined with DNN for prediction. Finally, the four forecasting results of each part are added together. Through experimental simulation, compared with the forecasting result of DNN and empirical mode decomposition (EMD) methods, the proposed method can effectively improve the load forecasting accuracy.
