This paper presents the impact of large-scale photovoltaic (PV) generation on power system oscillatory instability. Two models of PV generation systems, namely detailed dynamic and simplified models, have been studied in IEEE-14 bus test system typically used for power system oscillatory instability studies. Influence of radiation pattern, and size and location of PV generating system on the power system stability issue is thoroughly investigated. In PV generation penetration, two scenarios, namely concentrated and scattered are examined. Simulation shows that the increased penetration of PV system enhances power system oscillatory stability.
