摘要:
The accurate load forecasting is of great significance to power companies. In this paper, we proposed a probabilistic long-term load forecasting model based on stacked Long Short-Term Memory (LSTM).The data set is the load data of a power plant from 2005 to 2013.Firstly, data preprocessing is aimed to eliminate outliers and missing values, it can improve the accuracy of prediction. Secondly, we obtained the point prediction value with stacked LSTM, and the result shows that the proposed model performs better on prediction accuracy than other models, such as Support Vector Regression and Artificial neural network (BP). Finally, we proposed a probability density prediction method based on error statistics, comparing with point prediction method, it can provide more uncertain information for long-term load forecasting. © 2019 Association for Computing Machinery.
