Response of 100Kw Grid Connected PV System at Slava City –Iraq in the Event of Short Circuit and Loss of Grid

The importance of this paper is that in Iraq power system are continuously unstable due to increasing load demandy, lack of control, power losses, bad transmission lines, etc. So, we are trying to improve our grid power profile via Installing grid-connected PV systems. Despite the PV system, some factors have significant influence on dynamic voltage stability, such as temperature, quickly changing of solar radiation, and cloud shedding effects. This study investigates the response of a 100-kW grid-connected photovoltaic generation model in Slava city -Erbil-Iraqi Kurdistan during short circuit and loss of grid. Through MATLAB simulation, this model and its relationships with the power system & voltage and frequency were examined and the results of the simulation were carried out. The project work generally entails modelling the entire 100 kW PV Array panels, system interfaces, and 33 KV distribution feeder.
