A Simplified Voltage Stability Index (SVSI)
International Journal of Electrical Power and Energy Systems, 2014 Abstract This paper proposes an improved indicator to estimate the voltage stability margin in electric power systems, defined as the Simplified Voltage Stability Index (SVSI), which uses voltage measurements and some assumptions from the Thevenin model.

A new index for voltage stability monitoring and enhancement
International Journal of Electrical Power and Energy Systems, 1998 This paper presents a novel proximity index for voltage stability analysis. The proposed index is based on the angle between real and reactive power gradient vectors of load buses. A simple and computationally efficient algorithm is proposed for the evaluation of this index.

International Journal of Electrical Power and Energy Systems, 2012 Abstract Voltage stability improvement is an important issue in power system planning and operation. Voltage stability of a system depends on the network topology and settings of reactive compensation devices. This research first proposes an improved voltage stability index ( IVSI ) for network systems, and then presents an optimization method for ...

On‐line voltage stability index based on the voltage equation of transmission lines
IET Generation, Transmission and Distribution, 2016 This study proposes a new voltage stability index based on the voltage equation of transmission lines. The proposed index is obtained by using the characteristic that the sensitivity of voltage to power at the voltage collapse point tends to be infinite.

Linearized voltage stability index for wide-area voltage monitoring and control
International Journal of Electrical Power and Energy Systems, 2010 This letter addresses a linearized local voltage stability index based on wide-area measurement systems. The measurements allow reducing the problem of assessing the stability of a large system with n buses to the study of the local stability of n load buses.
