摘要:

本文通过利用深度学习的最新突破来开发概率PV预测器。它定制的预测工具,命名为编码器-解码器,实现计算日内多输出PV分位数预测,以有效地捕捉时间相关性。使用分位数回归训练模型,这是一种非参数方法,假设没有概率预测分布的先验知识。该案例研究是由光伏生产监测现场在列日大学(ULiège),比利时。由气候学实验室提供的区域气候模型的天气预报被用作深度学习模型的输入。通过连续排序概率和区间得分定量评估预报质量。结果表明,该架构提高了预测质量,计算效率高,可用于日内决策工具,以实现鲁棒优化。

英文摘要:

This paper develops probabilistic PV forecasters by taking advantage of recent breakthroughs in deep learning. It tailored forecasting tool, named encoder-decoder, is implemented to compute intraday multi-output PV quantiles forecasts to efficiently capture the time correlation. The models are trained using quantile regression, a non-parametric approach that assumes no prior knowledge of the probabilistic forecasting distribution. The case study is composed of PV production monitored on-site at the University of Liège (ULiège), Belgium. The weather forecasts from the regional climate model provided by the Laboratory of Climatology are used as inputs of the deep learning models. The forecast quality is quantitatively assessed by the continuous ranked probability and interval scores. The results indicate this architecture improves the forecast quality and is computationally efficient to be incorporated in an intraday decision-making tool for robust optimization.
