When the load of agriculture and illume is forecasted , the load is decomposed into stationary terms that is not related to meteorologic factors and random term that is related to meteorologic factors by use of wavelet analysis . because the forecasting accuracy of stationary term is higher and the amplitude of random term , although it is difficult to forecast , is smaller , so the impact of forecasting error bringing about by random factors on final forecasting result is weakened 在預測不同行業的負荷時,利用小波分析的方法對農業和照明負荷序列進行分解,然后將頻率較低的部分視為與氣象因素無關的穩定項進行處理,將頻率較高的部分視為與氣象因素相關的隨機項進行處理,由于穩定項預測精度高,隨機項雖較難預測但幅值較小,因此削弱了隨機因素帶來的預測誤差對最終結果的影響。
