Abstract :
This paper develops a method for reliably determining the set of low-voltage solutions which are closest to the operable power flow solution. These solutions are often used in conjunction with techniques such as energy methods and the voltage instability proximity index for assessing power system voltage stability. This paper presents an algorithm which provides good initial guesses for these solutions. The results are demonstrated on a small power system and on larger power systems with up to 2000 buses
