基于 Stacking元学习策略的电力系统暂态稳定评估
Power system transient stability assessment based on Stacking meta-learning strategy
摘要
Abstract
In order to increase singe model's accuracy in transient stability assessment of power systems, the transient stability assessment based on meta-learning strategy is studied, and a Stacking assessment model is presented. The base learning includes support vector machines, decision trees, naive Bayesian and K-nearest neighbor classifier. Linear regression is adopted as Stacking assessment model of meta-learning. The model uses the probabilistic output of base learning algorithm as input attributes in a new training set, and keeps the original class labels. The final transient stability assessment result is acquired after learning in the new training set by linear regression. The simulations on New England 39-bus and IEEE 50-machcine test systems show that the assessment performance of the proposed approach is better than that of the single models and provides a new way to assess power system transient stability.关键词
