Abstract :
[en] This chapter deals with voltage security assessment and its on-line application. Methods for contingency analysis are briefly reviewed. The associated con-cepts of transfer capability, loadability limit, and secure operation margin are explored in some detail. Methods for preventive security control are outlined. An application of on-line VSA in the control center of a real system is then de-scribed and typical results available to operators are presented.
