Optimal R-SFCL Location in Power Grid

Increased demand of capacity generation volume in distributed energetic power structures has led to an increase in fault current levels surpassing the maximum designed avoid ratings of the switchgear. In addition an unbalance in capacity level is also noticed during weakness 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 answer to suppress the overdone fault current questions and also to weaken voltage inconstancy by improving the rise rate of the temporary recovery voltage in Smart grids. However, new concern in such requests is about the optimum district 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 miscellaneous key locations in a smart gridiron. A Graphical User Interface (GUI) of MATLAB is developed to evaluate the influence of the proposed design on an IEEE benchmarked four-machine two-district test system. Three point 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.
