    Recently, power systems have become larger and more complicated, and the rate of occurrence of constant power loads has increased. Under a situation like this, concerns about voltage instability phenomena have been raised. Therefore, in addition to the conventional local voltage control, the necessity of a global on-line voltage control scheme has risen. In this paper, we propose a method of on-line voltage stability control including preventive and emergency-preventive controls to retain voltage stability even if a severe fault occurs. According to the result of contingency analysis for severe faults, we consider operation of control equipment as preventive control. And in the case that the fault seems severe still after preventive control, we consider load curtailment as emergency-preventive control. When we select the control equipment and loads to curtail, we use voltage stability index VIPI sensitivity. And we determine the amount of control and load curtailment using Optimal Power Flow calculation. The effectiveness of the proposed method is verified by simulations using a 28-bus system.
