The placement of the superconducting fault current limiter (SFCL) can be utilized to accommodate the increasing integration of distributed generations (DGs) in a power system. The installation of DGs in a power system can affect the power flow and the fault current patterns. Substantial changes in fault currents can cause coordination problems among the overcurrent relays. SFCL placement is a possible approach for accommodating the DGs by locally limiting the fault currents resulting from the DGs, while maintaining the existing relay settings. This paper presents a systematic procedure for analyzing the impacts of SFCL placement on DG expansion, considering the relay coordination in power systems.
