In this work the impact of large-scale photovoltaic power plants on power system dynamics and control is studied. The response of a small system (Kundur’s two areas example) and a case of the brazilian bulk power system with high PV generation is assessed as well as its effects on the oscilation modes and the transient stability. The General Electric dynamic model, available on the data base of the brazilian Indenpendent System Operator (ONS), is fully explained and thus adopted in the simulations. The impacts of the inverter’s strategy of voltage ride through on the system transient stability are also investigated. In the brazilian power system study, it is explored PV penetration scenarios up to 50% in the Northeast electric subsystem of Brazil.
