This paper presents a simulated analysis for the first time using the MATLAB Simulink tool prototype model to find the best configuration of the Superconducting Fault Current Limiter (SFCL) Impedance method. The goal here is to maintain the short circuit current within the circuit breaker’s power. To improve the reliability of the power system, various forms of decentralized generation plants (DGP) can be connected to the traditional electric grid (PS). Interconnected Decentralized Generation (DG) to an existing electric system provides a variety of benefits, including increased distribution system reliability, enhanced power quality, and decreased short circuit current, which can damage protective equipment. Since it gives virtually zero resistance in a steady-state, the Superconducting Fault Current Limiter (SFCL) is an ideal technology for reducing the magnitude of fault current (FC) in PS. Finally, the SFCL technique was used in the conventional grid interconnected with the wind farm to determine its optimal location in the smart grid (SG) with DG. However, we investigate the best location for SFCL in the smart grid, and our findings show that SFCL at the integrating point is the right alternative.
