Abstract

With the rapid growth of power grid in China, it is becoming more and more important to forecast short-term power load. Aiming at the problems of complex causes of short-term load forecasting, large amount of data, low efficiency and poor accuracy of traditional model forecasting methods, and the single model forecasting can no longer adapt to the current power load changes, a short-term power load forecasting method based on hybrid ReliefF-PMI-IGWO was proposed. Firstly, two Filter feature selection methods based on hybrid ReliefF and Partial Mutual Information (PMI) were used to screen out irrelevant and redundant input features, and a smaller feature subset was obtained. Then the Wrapper method is used for further screening, among which the Wrapper method selects Improved Grey Wolf Optimization (IGWO) algorithm, and its accuracy is significantly improved. Combined with the case analysis of the hourly load data of China Midea HVAC and Nongfu Spring from May to August 2017, and compared with other five traditional models. The simulation results show that the MAE and MAPE obtained by the proposed model are 49.54, 1.62 and 71.34, 1.98, respectively, which are significantly better than other models, and the prediction accuracy of the proposed model is the highest and the closest to the real value.
