In this work, a novel method for choosing a global set of preventive controls for voltage stability analysis is developed. The method depends on top-down and bottom-up approaches to obtain the set of controls according to voltage stability sensitivity analysis. At first, the sensitivities of the voltage stability margins of network buses to preventive controls are obtained. The average of the sensitivities referred to each preventive control is then calculated, which gives an indicator about how each preventive control can improve the voltage stability margin of power system. The average is done over the sensitivities of different critical buses located at different locations. The two approaches (top-down and bottom-up) are then performed on the averaged sensitivities to choose a set of the most efficient controls. The proposed method is able to simultaneously eliminate the impact of system contingencies on network buses. The proposed method is checked on the IEEE 39 bus network. The results demonstrate the accuracy and the validity of the proposed method for control selection.
