基于代价敏感支持向量机和多变量决策树的分级自适应暂态电压稳定评估OA北大核心CSTPCD
Hierarchical Self-adaptation Transient Voltage Stability Assessment Based on Cost-sensitive SVM and Multivariate Decision Tree
为解决暂态电压稳定评估中失稳工况漏判率高的问题、提升多变量决策树(multivariate decision tree,MDT)应用能力,提出一种分级代价敏感多变量决策树(hierarchical cost sensitive multivariate decision tree,HCS-MDT)评估方法.基于可量测电气量时空联合拓展构建特征,利用改进经验风险的代价敏感支持向量机(cost sensitive support vector mac…查看全部>>
In order to solve the problem of the high mis-judgment rate under the unstable conditions in the transient voltage stability assessment and improve the application of the multivariate decision tree(MDT),a hierarchical cost sensitive-multivariate decision tree(HCS-MDT)assessment is proposed.Based on the spatiotemporal joint expansion of the measurable electrical quantities to construct the features,the cost-sensitive support vector machine(CS-SVM)with the imp…查看全部>>
