摘要
运用多个预测效果的评价指标综合比较多种中长期电力负荷预测方法,结合熵权的方法客观地为每种预测方法分配权重,将各方法的预测结果加权求和得到最终的预测结果。实例表明,该方法在提高预测精度的同时减小预测的风险。
Forecasting methods are comprehensively compared using different evaluation indices, and the weight is objectively calculated for every medium-long power load forecasting method by using entropy weight. The forecasting resuits of all the methods are then weighted and summed, leading to the final forecasting result. The combination forecasting method can increase forecasting accuracy and reduce risks at the same time.
