AI总结:

本文针对能源交易中的不确定性量化问题,提出一种可扩展的多元函数时间序列无分布预测带方法,能保证无条件覆盖和渐近精确性,并成功应用于意大利天然气市场的需求与报价曲线预测。

摘要:

预测中的不确定性量化是能源交易中一个非常重要的课题,因为了解能源市场的状态可以使交易者直接评估其自身报价/投标的影响。为此,我们提出了一种可扩展的程序,该程序在时间序列背景下为多元函数响应变量输出闭式同时预测带,并且能够在某些条件下保证无条件覆盖和渐近精确性方面的性能界限。在合成数据上评估其性能后,该方法被用于为意大利天然气市场的每日需求和报价曲线构建多元预测带。

英文摘要:

Uncertainty quantification in forecasting represents a topic of great importance in energy trading, as understanding the status of the energy market would enable traders to directly evaluate the impact of their own offers/bids. To this end, we propose a scalable procedure that outputs closed-form simultaneous prediction bands for multivariate functional response variables in a time series setting, which is able to guarantee performance bounds in terms of unconditional coverage and asymptotic exactness, both under some conditions. After evaluating its performance on synthetic data, the method is used to build multivariate prediction bands for daily demand and offer curves in the Italian gas market.
