分位数回归用于GEFCom2017概率负荷预测的合格匹配

Quantile Regression for Qualifying Match of GEFCom2017 Probabilistic Load Forecasting

Florian Ziel

摘要:

我们提出了一种简单的基于分位数回归的预测方法,并将其应用于2017年全球能源预测竞赛(GEFCom 2017)的概率负荷预测框架中。每小时负荷数据经过对数转换并分为长期趋势分量和剩余项。关键的预测要素是剩余期的分位数回归方法,该方法考虑到每周和每年的季节性,例如它们的相互作用。温度信息仅用于稳定长期趋势分量的预测。公众假期信息被忽略。尽管如此,预测方法在开放数据跟踪中排名第二,在确定数据跟踪中排名第四,这是显着的模型简单。该方法也始终优于Vanilla基准。

英文摘要:

We present a simple quantile regression-based forecasting method that was applied in a probabilistic load forecasting framework of the Global Energy Forecasting Competition 2017 (GEFCom2017). The hourly load data is log transformed and split into a long-term trend component and a remainder term. The key forecasting element is the quantile regression approach for the remainder term that takes into account weekly and annual seasonalities such as their interactions. Temperature information is only used to stabilize the forecast of the long-term trend component. Public holidays information is ignored. Still, the forecasting method placed second in the open data track and fourth in the definite data track with our forecasting method, which is remarkable given simplicity of the model. The method also outperforms the Vanilla benchmark consistently.
