Abstract
A method and device for labeling transient voltage stability samples in a power grid based on semi-supervised learning are provided. The method includes: S: obtaining a transient voltage time series trajectory V formed for each load bus in the power grid under N transient operating scenarios; S: preliminarily labeling the stability status of each transient operating scenario with a voltage time series dataset V, and integrating the labeling result Yinto a class label dataset Y; S: constructing a voltage stability sample set S={(V, Y)|1≤i≤N}, dividing S into sample subsets Sand S; S: labeling samples in Sby using a semi-supervised clustering learning method and a semi-supervised classification learning method to obtain result datasets Yand Yrespectively; S: performing interactive verification on Yand Y, and updating Sand S; and S: performing repeated iteration on the Sand the S
