Abstract :
In this paper a unique methodology for assessment of voltage stability is proposed considering economic criteria using the concept of equivalencing the multi-bus system to a two bus radial system and by studying the necessary parameters of the equivalent system. Hence, a generalized global voltage stability indicator being developed, it has been applied to a typical 6-bus system and a practical 203-bus WBSEB system. Test results have proved that this new network equivalent method is promising for voltage stability study of power system in global scenario and is applicable to any multi-bus power network.
