Linearized voltage stability index for wide-area voltage monitoring and control

International Journal of Electrical Power & 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.
