英文摘要：
  Motivated by the increasing integration among electricity markets, in this paper we propose two different methods to incorporate market integration in electricity price forecasting and to improve the predictive performance. First, we propose a deep neural network that considers features from connected markets to improve the predictive accuracy in a local market. To measure the importance of these features, we propose a novel feature selection algorithm that, by using Bayesian optimization and functional analysis of variance, evaluates the effect of the features on the algorithm performance. In addition, using market integration, we propose a second model that, by simultaneously predicting prices from two markets, improves the forecasting accuracy even further. As a case study, we consider the electricity market in Belgium and the improvements in forecasting accuracy when using various French electricity features. We show that the two proposed models lead to improvements that are statistically significant. Particularly, due to market integration, the predictive accuracy is improved from 15.7% to 12.5% sMAPE (symmetric mean absolute percentage error). In addition, we show that the proposed feature selection algorithm is able to perform a correct assessment, i.e. to discard the irrelevant features.

中文摘要：
受电力市场一体化程度不断提高的推动，本文提出了两种不同的方法来将市场一体化纳入电价预测，并提高预测性能。首先，我们提出了一种深度神经网络，该网络考虑了连接市场的特征，以提高本地市场的预测精度。为了衡量这些特征的重要性，我们提出了一种新的特征选择算法，该算法利用贝叶斯优化和方差函数分析来评估特征对算法性能的影响。此外，利用市场整合，我们提出了第二个模型，通过同时预测两个市场的价格，进一步提高了预测精度。作为一个案例研究，我们考虑了比利时的电力市场以及使用各种法国电力功能时预测精度的提高。我们表明，这两个提出的模型带来了统计上显著的改进。特别是，由于市场整合，预测精度从15.7%提高到12.5%sMAPE（对称平均绝对百分比误差）。此外，我们还证明了所提出的特征选择算法能够进行正确的评估，即丢弃不相关的特征。
