Increased demand of capacity generation ability in distributed energetic power methods has led to an increase in fault current levels surpassing the maximum designed avoid ratings of the switchgear. In addition an unbalance in physical ability level is also noticed during mistake owing to the unification of AC and DC micro grids consisting of wind and photovoltaic farms. Resistive type Superconducting Fault Current Limiter (R-SFCL) maybe the best resolution to suppress the overdone fault current questions and also to humiliate voltage imbalance by improving the rise rate of the temporary recovery voltage in Smart grids. However, new concern in such uses is about the optimum region of R-SFCL. In this work, we have modeled a HTS located R-SFCL using E-J traits of the superconductor and implemented it at differing key locations in a smart gridiron. A Graphical User Interface (GUI) of MATLAB is developed to evaluate the influence of the proposed means on an IEEE benchmarked four-machine two-district test system. Three state faults of various ratings are studied accompanying and without SFCL at various indispensable content of the smart grid, listening the power flows. Such studies on best location of SFCL are main to maximize the influence of fault alleviation in an extended network of Power Grid.
