Research on the application of artificial intelligence (AI) methods in power grid analysis has been widely conducted. The flow dataset required for training AI models is not uniformly distributed, and to improve quality dataset, related research generally applied tuning that tend have a more uniform sample distribution, resulting improved performance models. However, lack evaluate uniformity di...

The problem of classification for imbalanced datasets is frequently encountered in practical applications. data to be classified this are skewed, i.e., the samples one class (the minority class) much less than those other classes majority class). When dealing with datasets, most classifiers encounter a common limitation, that is, they often obtain better performances on class. To alleviate stud...
