To cope with the problem that emergency control measure is difficult to implement under some scenes and improve the friendliness of user power supply and accuracy of security and stability control, emergency load regulation for security and stability control is studied. In the view of stability emergency control, the characteristic of emergency load regulation is analyzed. Compared to emergency load shedding, the mechanism of the effects of emergency load regulation for stability control is studied based on EEAC（Extended Equal Area Criterion）, of which the control result is influenced by emergency load regulation performance. The conclusion is verified by simulating and analyzing emergency regulation electrolytic aluminum load for stability control in real pow
