Analysis of large scale PV penetration impact on IEEE 39-Bus power system

The integration of Renewable energy sources (RES) into the traditional electric grid infrastructure is a challenging task due to their intermittent nature as well as the technical and non-technical complexities. This paper presents the impacts of large scale Photovoltaic (PV) penetration into the IEEE 39-bus test system. The modeled PV plants are integrated at suitable locations to study the impacts of penetration using Siemens PSS/E (Power System Simulator for Engineers) software. The maximum PV integration capacity is determined based on the variation in slack bus generation with gradual increment in penetration levels. Furthermore, the simulations are carried to study the effect of sudden loss of PV plants, three phase faults at solar PV plant connected bus for different PV penetration levels. The simulation results of PV integration reveal that the dynamic response of PV plants aids to meet the peak demands to enhance the reliability of smart electric grids.
