Energy usage increases day to day. To overcome this usage, nonconventional energy sources are combined with conventional units here the loads, powers and frequency marched at load side and source side. In this work fuel cell, P-V power & wind energies are combined. The combination of these DGs increase fault current levels. Here we are using resistive type superconducting fault current limiters(R-SFCL) to limit the fault currents. SFCL gives a very fast response it limits fault current within the first cycle. It's having good characteristics, as compared to conventional protective devices SFCL gives good response and high efficiency. In this work resistive type superconducting fault current limiter improves the transient stability, voltage profile, power ratings and reduce harmonics at different fault conditions. This work is done by using MATLAB / Simulink.
