摘要:

准确的电价预测对电力系统管理与智能应用开发至关重要。俄乌冲突后,欧洲电价大幅上涨且波动剧烈,对现有预测方法构成挑战。本文提出一种用于德国-卢森堡日前电价的长短期记忆(LSTM,Long Short-Term Memory)模型,以应对这些挑战。LSTM的循环结构使模型能够适应趋势,同时对均值和标准差的联合预测实现了概率预测。我们采用一种受物理学启发的方法——超统计学(superstatistics)来推导电价统计特性的解释,结果表明LSTM模型能够忠实地复现电价及其波动率。

英文摘要:

Accurate forecasts of electricity prices are crucial for the management of electric power systems and the development of smart applications. European electricity prices have risen substantially and became highly volatile after the Russian invasion of Ukraine, challenging established forecasting methods. Here, we present a Long Short-Term Memory (LSTM) model for the German-Luxembourg day-ahead electricity prices addressing these challenges. The recurrent structure of the LSTM allows the model to adapt to trends, while the joint prediction of both mean and standard deviation enables a probabilistic prediction. Using a physics-inspired approach - superstatistics - to derive an explanation for the statistics of prices, we show that the LSTM model faithfully reproduces both prices and their volatility.
