Transient Angle Stability Assessment and Interpretability Analysis Based on Gradient Boosting Enhanced With Step-wise Feature Augmentation
基于数据驱动的电力系统暂态功角稳定评估虽然可以提供较为准确的结果,但其评估结果缺乏可解释性,导致难以应用于工程实际中.针对该问题,提出一种基于逐步特征增广梯度提升(gradient boosting enhanced with step-wise feature augmentation,AugBoost)的暂态功角稳定评估及可解释性分析方法.首先,通过训练AugBoost评估模型,建立电力系统输入特征与暂态功角稳定指标之间的映射关系;其次,将相…查看全部>>
Although the transient angle stability assessment of power systems based on data-driven can provide more accurate results,it is difficult to apply in engineering practice due to the lack of interpretability of the results.To solve this problem,an analysis method of transient angle stability assessment and in-terpretability based on gradient boosting enhanced with step-wise feature augmentation(AugBoost)was proposed.Firstly,the mapping relationship between th…查看全部>>
