Short-term power load forecasting is receiving increasing attention, especially because of intrinsic difficulties and practical applications. In this paper, the novel integrated approaches, combining longitudinal data selection (LDS), singular spectrum analysis (SSA) technique, adaptive particle swarm optimization based on gravitational search algorithm (APSOGSA) and the nonlinear multi-layer perceptron neural network (NMLPNN), were proposed for the short-term power load forecasting. Firstly, the LDS, which guarantees that the input and output data have the same properties to ensure abundant performance. Then, the SSA technique is used for identifying and extracting the trend and seasonality of power load time series. Finally, the NMLPNN, which is optimized by the APSO, GSA, and APSOGSA, is utilized to deal with the irregularity and volatility of the power load. These integrated methods are applied to forecast half-hour power load data from New South Wales, Queensland and Singapore. By comparison of the obtained experimental results, the proposed SSA-APSOGSA-NMLPNN integrated method indicates the superiority and promising performance and has a good robustness.
