基于隐式生成集成后处理的概率多变量电价预测

Probabilistic multivariate electricity price forecasting using implicit generative ensemble post-processing

Tim Janke, Florian Steinke

摘要:

预测不确定性的可靠估计是风险敏感最优决策的关键。在本文中,我们提出了隐式生成集成后处理,多变量概率电价预测的新框架。我们使用一个基于点预测模型集合的无似然隐式生成模型来生成具有一致依赖结构的多变量电价场景,作为联合预测分布的表示。我们的集成后处理方法优于成熟的模型组合基准。这一点在德国日前市场的数据集上得到了证明。由于我们的方法在特定领域的专家模型集合之上工作,因此可以很容易地部署到其他预测任务中。

英文摘要:

The reliable estimation of forecast uncertainties is crucial for risk-sensitive optimal decision making. In this paper, we propose implicit generative ensemble post-processing, a novel framework for multivariate probabilistic electricity price forecasting. We use a likelihood-free implicit generative model based on an ensemble of point forecasting models to generate multivariate electricity price scenarios with a coherent dependency structure as a representation of the joint predictive distribution. Our ensemble post-processing method outperforms well-established model combination benchmarks. This is demonstrated on a data set from the German day-ahead market. As our method works on top of an ensemble of domain-specific expert models, it can readily be deployed to other forecasting tasks.
