- 聚焦预测有效性与标准化评估,适合能源市场研究者参考
电力价格预测已成为能源市场决策的关键工具,尤其在可再生能源渗透率上升带来更大波动性和不确定性背景下。传统研究长期以提供单一数值的点预测为主,无法量化风险。随着新能源接入、智能电网和监管变化,概率预测需求日益迫切,能更全面评估风险并支持市场参与。本文综述了概率预测方法的发展脉络,涵盖贝叶斯与分布型方法、分位数回归,以及近年来可证实性预测的进步。重点强调以预测有效性为导向的新方法,解决了不确定性估计中的关键缺陷。此外,本综述扩展至日前市场之外的日内与平衡市场,这些市场因时间粒度更高、实时运行约束更强而更具挑战。文章分析了前沿方法、核心评估指标及现存难题,如预测有效性、模型选择与缺乏标准化基准,为研究人员与从业者提供了全面及时的参考资源。
原文摘要 · Abstract (English)
Electricity price forecasting has become a critical tool for decision-making in energy markets, particularly as the increasing penetration of renewable energy introduces greater volatility and uncertainty. Historically, research in this field has been dominated by point forecasting methods, which provide single-value predictions but fail to quantify uncertainty. However, as power markets evolve due to renewable integration, smart grids, and regulatory changes, the need for probabilistic forecasting has become more pronounced, offering a more comprehensive approach to risk assessment and market participation. This paper presents a review of probabilistic forecasting methods, tracing their evolution from Bayesian and distribution based approaches, through quantile regression techniques, to recent developments in conformal prediction. Particular emphasis is placed on advancements in probabilistic forecasting, including validity-focused methods which address key limitations in uncertainty estimation. Additionally, this review extends beyond the Day-Ahead Market to include the Intra-Day and Balancing Markets, where forecasting challenges are intensified by higher temporal granularity and real-time operational constraints. We examine state of the art methodologies, key evaluation metrics, and ongoing challenges, such as forecast validity, model selection, and the absence of standardised benchmarks, providing researchers and practitioners with a comprehensive and timely resource for navigating the complexities of modern electricity markets.
