摘要: 为了解决当下用电负荷预测精度不高,难以很好模拟实际用电负荷的分布情况而不能对未来的负荷数据进行合理预测的问题,实现了基于随机森林的分类模型、回归模型以及结合Weka的时间序列模型,对某省份的负荷数据进行预测,通过对不同模型的大量的实验及评估,发现这三个模型皆能合理地预测未来的用电负荷数据。此外,在同一评估指标下随机森林算法结合WEKA中的时间序列模型的方法能够较好地预测未来时刻的负荷数据。

Abstract: In order to improve the accuracy of electricity load prediction and solve the problem of simulating the actual distribution of electricity load, it implements the classification model, regression model and time series model of combining the Weka which are based on random forest to forecast the electricity load data of a certain province. After a large number of experiments and evaluation on different models, it finds that the three models can reasonably predict the future of electricity load data. In addition, under the same evaluation index the model which combines the random forest algorithm and time series of WEKA can get better result when predicting the future moment of electricity load data.
