摘要:

鉴于现有碳价区间预测模型在追求高覆盖率时常面临区间过宽的问题,本文创新性地提出了一种基于混合分位数的时变权重组合预测模型。首先对Transformer架构进行了优化,通过时序分块与两阶段平稳处理策略,大幅减少了模型参数量,避免了数据分布特性被过度平滑所损耗,从而增强了模型的稳定性和预测准确性。接着,结合TimesNet模型的多周期特征识别能力,分别进行混合分位数预测。针对时间序列数据随时间变化的特点,本文开发了一种基于多目标优化的上下界时变权重组合算法,有效地融合了两种预测模型的优点,实现了区间宽度与覆盖率之间的合理平衡。实验结果显示,本文提出的模型在多个碳交易试点应用中表现优异,显著提高了预测区间的适用性和精确度,为行业从业者提供了一种既能保证覆盖率又能控制区间宽度的碳价预测新方法。

Abstract:

The accurate prediction of carbon prices provides valuable information to practitioners, supports market development, and help the dual-carbon target to be realized on schedule. Therefore, how to construct an efficient, accurate and stable carbon price prediction model has become a major research issue. However, carbon price interval prediction poses significant challenges due to the need to balance interval width and coverage. An innovative time-varying weighted ensemble interval prediction model, based on mixed quantile regression, is proposed to quantify the uncertainty of carbon prices. Two hybrid quantile models are constructed using advanced time-series deep learning algorithms for predicting carbon price intervals. To improve prediction precision, a multi-objective optimization algorithm is developed, dynamically assigning time-varying weights to optimize the upper and lower bounds of combined interval predictions, striking a balance between interval width and coverage. Historical carbon trading data from two representative Chinese pilots, sourced from the Wind database, are used for empirical validation. The results demonstrate that the proposed model performs robustly across various pilot applications, significantly enhancing the reliability and precision of prediction intervals. A valuable tool is provided for practitioners, enabling carbon price predictions with high coverage while effectively controlling interval width.
