Analysis of Impacts of Superconducting Fault Current Limiter (SFCL) Placement on Distributed Generation (DG) Expansion

초록

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.
