Tower Damage Prediction for Distribution Network Based on Unbalanced Sample Data Under Typhoon Disasters
摘要
Abstract
Given that extreme weather events with low probability but high impact often exhibit the characteristic of imbalanced sample data,a Wasserstein generative adversarial network(WGAN)based deep ensemble learning(DEL)model is proposed to achieve the accurate prediction of damaged towers in distribution network in scenarios with imbalanced sample data.Firstly,using preprocessed meteorological,geographical,and electrical data as inputs,the WGAN is employed to generate samples of damaged towers.Subsequently,a DEL model is constructed through Stacking,utilizing Bagging-integrated random forest and boosting-integrated gradient boosting decision tree as base learners,and a neural network as a meta-learner.Finally,taking the distribution network towers in Zhanjiang City of China during Typhoon Talim(No.4 in 2023)as an example,the predicted distribution of damaged towers is visualized.The model is evaluated for interpretability using the SHAP method to analyze the influence mechanism of feature variables on the prediction results.The results demonstrate that,compared to traditional data augmentation and machine learning algorithms,the proposed model exhibits higher prediction accuracy and superior data information mining capabilities,enabling effective tower damage prediction in distribution network even when data samples are insufficient.关键词
