Xiuqin Xu, Ying Chen, Yannig Goude, Qiwei Yao

摘要:

电力负荷曲线的概率预测对于在日益波动和竞争激烈的能源市场中进行有效的调度和决策至关重要。我们提出了一种新的方法来构建概率预测曲线(PPC),这导致了一个自然的和新的分位数的定义曲线到曲线线性回归的上下文中。PPC有三种类型:预测集、预测带和预测分位数,所有这些都是在预先指定的名义概率水平上定义的。在仿真研究中,PPC在多种数据生成机制下都能获得较好的覆盖概率。在法国日负荷曲线的一天前预测中,PPC在预测精度、覆盖率和预测带平均长度方面优于几种最先进的预测方法。预测分位数曲线提供了有见地的信息,这是高度相关的电力供应管理中的对冲风险。

英文摘要:

Probabilistic forecasting of electricity load curves is of fundamental importance for effective scheduling and decision making in the increasingly volatile and competitive energy markets. We propose a novel approach to construct probabilistic predictors for curves (PPC), which leads to a natural and new definition of quantiles in the context of curve-to-curve linear regression. There are three types of PPC: a predictive set, a predictive band and a predictive quantile, all of which are defined at a pre-specified nominal probability level. In the simulation study, the PPC achieve promising coverage probabilities under a variety of data generating mechanisms. When applying to one day ahead forecasting for the French daily electricity load curves, PPC outperform several state-of-the-art predictive methods in terms of forecasting accuracy, coverage rate and average length of the predictive bands. The predictive quantile curves provide insightful information which is highly relevant to hedging risks in electricity supply management.
