Abstract :The increasing integration of photovoltaic insert ignore into journalissuearticles values(PV); plants in conventional power systems has led to the need to examine the effects of these plants on the system dynamics. In this study, a well-known IEEE-9 bus power system is modified by integrating PV plant in DigSilent Powerfactory environment. Then, 3 transient cases are tested by using PV plant control units designed by Western Electricity Coordinating Council insert ignore into journalissuearticles values(WECC);. The effect of load and line transient disconnections and 3-phase short circuit fault on modified power system are investigated as case-I, case-II, and case-III, respectively. In all cases, two sub-cases are considered according to the location. As a result, comparison of PV system reactive power control methods insert ignore into journalissuearticles values(RPCM); is analyzed in terms of voltage stability in these 3 cases.
