Abstract:Accurate power load forecasting is beneficial to ensure the safety,stability,efficiency and economy of grid operation.In order to improve the prediction accuracy,a PSO improved T-S (Takagi-Sugeno) fuzzy neural network method is applied.The importance of data preprocessing to improving the input is analyzed and an improved T-S fuzzy neural network algorithm that can make the learning rate and smoothing factor adjust dynamically is discussed.Therefore,it can make PSO find the optimal parameters.And then,combined with historical load data and related influencing factors,it is concluded that the improved T-S fuzzy neural network has higher control precision in short-term power load.
