Abstract: Deregulation of electric power market and aggregation of renewable resources raise the need for new hour-ahead load forecasting models. This paper proposes a new hybrid data-driven method for hour-ahead electrical load forecasting based on innovative features that represents the nonlinear and dynamic characteristics of electrical load. These features predict hourly load changes and improve the accuracy and performance of STLF. These innovative features first construct the pool of features along with historical load variables. Then, a feature selection method called RReliefF is used for choosing most relevant features and finally, a multi-layer perceptron neural network is employed as a forecasting engine—due to its advantages such as self-organization, fault tolerance and ease of integration in existing technologies. The efficiency of the proposed model is evaluated through various comparative experiments and compared with benchmark models using the three years’ real energy market data from New England ISO by four evaluation criteria. The results demonstrate the superiority of proposed method in forecasting performance for the period of analysis including 12 test months as well as special days.
