© 2017 IEEE. Transient stability studies are the key for providing secured operating configurations in power-grid networks. Penetration of a large-scale photovoltaic energy into an existing power grid is expected to highly increase, which will affect operational characteristics. This paper investigates transient stability analysis and the impact of large scale grid-connected photovoltaic (PV) system on electric power-grid networks. Three different scenarios, with their relevant dynamic models with centralized PV farm, are considered at medium voltage level without voltage regulation capabilities. Conducted simulation results show the impact of increased PV penetration on both steady state and transient stability performance. Results in this paper are conducted using a power system software for the design, simulation, operation, and automation of power network and large scale photovoltaic system.
