چکیده مقاله:

In this paper for the purpose of system security assesment a new security constraint based on the voltage stability and loadability limit (VSLL) of load buses is presented. Following a line outage or load increase, evaluation of these security constraints enable us to have a more realistic assesment of system security level. For evaluation of VSLL of load buses a simple and fast method based on the concept of Thevenin equivalent impedance is presented.
