Considering the effects of the outside factor and the periodic change of the predictand, the multivariate mixed threshold regression model with periodic components is developed. 摘要在綜合考慮預測對象的周期變化和前期外部因子的共同作用后，給出帶有周期分量的多元混合門限回歸模型。
In the time sequence the trend component and periodical component were considered to make the load forecasting model more coincident with the features of power loads. 同時，時間序列考慮了趨勢分量和周期分量，使負荷預測模型更加符合電力負荷特性。
