dc.description.abstractThe National Society of Electricity and Gas of Algeria (SONELGAZ) is interconnecting the national power grid with the isolated power grids in the south of the country. One such grid is the Pole In Salah-Adrar Timimoune (PIAT). It is an exceptional power grid of considerable installed renewable energy sources values. The paper investigates the short-circuit phenomenon in the PIAT. The share of the renewable sources in the PIAT fault current is studied, and the difference between fault currents with and with-no integration of renewable sources are studied in order to find out if the protection parameters need to be changed in the case of the absence of renewable sources. Also, to interconnect the PIAT with other power grids, the PIAT short-circuit power is studied at different short-circuit points in the current situation and after the planned increase in the PV installed power. It is shown that the actual installed renewable sources contribute to the fault current with less than 10 % regardless of the fault position. Increasing the installed power by 300 % would increase the short-circuit power with less than 10 %. A method is suggested to determine the power grid short-circuit power using the short-circuit admittance instead of the impedance
