The authors have combined a multiple regression model of statistical methods and a random forest of machine learning methods and applied to a seasonal model to forecast power demand. Therefore, this time, we predicted the power demand by a neural network, and confirmed the validity of the proposed method by comparing and verifying it with the proposed method. Furthermore, in the proposed method, effective explanatory variables were selected, learning was improved, and improvement in prediction accuracy was confirmed. In this study, using one method and one modeling period is considered as a risk, so the risk was reduced by combining methods with different prediction characteristics and multiple modeling periods.
