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(mén)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(shí)，時(shí)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。
