With the deepening of the research on voltage stability(VS), the methods for analyzing VS have also been further developed. Although the probability of voltage collapse has been greatly reduced compared to before, the research on VS has always been a hot topic due to the seriousness of its consequences. This paper studies the sensitivity method of VS and other related calculation methods, corrects the power system through BP neural network, compares the load margin values obtained by the VS calculation method before and after the correction, and finds that the load margin obtained by the BP neural network algorithm proposed in this paper degree value error is minimal.
