| Abstract: | Based on DB wavelet and the BP neural network,a method of short-term power load forecasting was presented. The forecasting model was provided by using the characteristics of DB wavelet which can decompose time series into any level and RBP network output feedback as input data which can increase information amount. A practical example proves that this method has higher forecasting accuracy in short-term load forecasting. |
