Overcoming the drawbacks of large-scale Photovoltaic (PV) generation in electric power networks is a significant research topic for electric utilities. In this work, we focus on PV systems operating under high temperature environments such as hot desert conditions. Voltage stability, transient stability and general performances are assessed function of an experimental temperature profile. The study is performed on the IEEE 9-bus system model, in which the effects of temperature variation on transient stability of the system are assessed. A Cooling system is introduced to reflect the transient response characteristics of PV generation model established in DIgSILENT/Power Factory.
