Abstract
Voltage stability analysis of multi machine system is evaluated through continuation power flow (CPF) in this paper. The performance study of SVC is accomplishd in IEEE 57 bus test system for the enrichment of voltage stability through Power System Analysis tool box (PSAT).When the system undergoes unexpected over loading, it might be voltage collapse. The voltage collapse is main issue which can be a serious result of voltage instability. So the stability is affected. It needs compensation to improve the stability from the disturbances. Here the system is analyzed by CPF to improve the stability. Various operating conditions like without SVC and with SVC tuned by MVO are used to estimate the performance of the proposed procedure. The results show that the system with SVC tuned by MVO gets more flexibility in load side and gives stability than the system without SVC.
