ABSTRACT

In this paper voltage stability is evaluated by both dynamic PV curve and time domain simulations with a developed and detailed model of STATCOM. Also effect of load with different power factors in voltage stability assessment is studied. The results presented in this paper show that STATCOM can greatly improve the voltage stability and maximum loading capacity of power systems, especially in lower power factors. It is also shown that the margin of stability can be easily and effectively evaluated by PV curves because they cover a wide range of system operating conditions. Also it is illustrated that reactive power has more effects on voltage stability rather than real power.
