[0039] Such as Figure 1 to Figure 4 As shown in , a typical power consumption pattern extraction method suitable for massive unbalanced load data includes the following steps:
[0040] (S1) Use the Borderline-SMOTE training sample category imbalance processing method to process the load data; the Borderline-SMOTE training sample category imbalance processing method first finds out the minority class training samples that are similar to the majority class according to the Euclidean distance between the load curves. For the adjacent boundary elements, the SMOTE algorithm is used to randomly synthesize new training samples for the boundary set, and the data synthesis ratio is adjusted to roughly balance the number of samples in the majority class and the minority class. The specific steps of the Borderline-SMOTE training sample category imbalance processing method are as follows:
[0041] (S11) Calculate each sample point p in the minority class P in the entire training set T ...
