Recently, a large amount of Photovoltaic Generations (PV) are installed into a power system in large quantities. Therefore electric power suppliers must forecast the net demand profile that excluded quantity of PV generation from demand load. In this paper, a new technique of net demand forecasting is proposed. At first, we propose using Taguchi's T method (T method) that is one of the multivariate analysis techniques for net demand forecasting. Moreover, we propose data-select T method as improvement of T method for using net demand forecasting with less data. Furthermore, we examine the net demand forecasting technique, which is based on data in the last month on a forecasting day, by T method and data-select T method. In addition, the effectiveness of the proposed method by comparing the multiple regression analysis is discussed.
