INVESTIGATION WITH MODAL ANALYSIS OF EFFECTS OF HIGH PV PENETRATION ON POWER SYSTEM VOLTAGE STABILITY

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.
