Review analysis of voltage stability in power system

According to the research on voltage stability of power system at home and abroad, the definition and classification of power system voltage stability are summarized and compared, and then analyzed from two aspects of static and dynamic voltage instability mechanism. In this paper, power system voltage stability analysis methods are summarized as static voltage stability analysis and dynamic voltage stability analysis, and the present research situation of the two kinds of analysis methods is analyzed and reviewed. Finally, the future development trend is prospected
