چکیده مقاله :
Abstract- The integration of distributed generation (DG) and renewable energy sources (RES) into microgrids has significantly increased fault current levels, challenging system protection and stability. To ensure reliable operation while accommodating growing DG capacity, microgrids require advanced solutions to manage fault currents without compromising transient stability. Fault current limiters (FCLs) emerge as an effective solution to suppress fault currents, enhance protection coordination, and facilitate seamless microgrid operation during fault conditions. This paper proposes a modified series resonant fault current limiter (MSRFCL) designed for controllable fault current suppression in microgrids. The new topology addresses the limitations of conventional SRFCLs by integrating adaptive control capabilities, ensuring compatibility with microgrids’ voltage sag conditions. To validate the proposed FCL’s efficacy, comprehensive simulations were conducted in PSCAD/EMTDC, analyzing fault current mitigation, fault ride through performance and protection under varying microgrid scenarios
