Abstract

This paper shows the effects of high PV
integration on the power system voltage stability. PV power plant was applied
to the IEEE 30 bus test system. Modal analysis method is used to show the
effect of PV integration on power system voltage stability. The power rate of
synchronous generator in the IEEE 30 bus system is increased to show the power
system stability effect of high PV penetration and then the PV generation with
the same power rate is connected appropriate bus in power system. The modal
analyses of systems are done without any PV generation and with collective and
scattered PV generation at various rates. In PV penetration, two scenarios,
namely collective and scattered are examined. The results obtained showed that
the increased penetration of PV system affects the power system voltage
stability positively.
