One of the biggest problems encountered in Photovoltaic (PV) systems is to contribute to the fault current in case of failure. The fault current profile differs considerably from the system without the PV as the number of PV increases. Operation of the protection devices is also affected by this fault current change. In this paper, grid-connected solar energy system was designed in PSCAD program and the short current values given to the grid were examined. The contribution of the PV systems to the grid was examined for the fault condition. Both fault and normal cases were compared by the currents
