摘要
应用模糊可变方法对电力负荷进行了预测。利用负荷与三大产业的生产总值的历史数据构造指标集,并应用差异函数建立电力负荷预测模型。该方法能够科学、合理地确定与电力负荷相关的各个研究指标处于级别区间的相对隶属函数,并根据指标重要性进行二元比较与量化,从而合理地确定各个指标的权重,得出电力负荷预测的级别特征值。实例证明,方法是合理的。
A new power load prediction model, the variable fuzzy sets method, is presented. The historical data are adopted to construct indexes sets and solve the prediction model. The method can scientifically and reasonably determine relative membership functions of disquisitive indexes at level interval that relating to power load, also it can fully use one's experience and knowledge, qualitative and quantitative information of index system to obtain weights of indexes for power load prediction operation. The numerical example has shown that the proposed method is feasible and effective, and the evaluation results are reasonable.
