Globally there has been a sharp increase in the number of renewable energy sources (RESs) connected to electrical power systems (EPSs). At the same time, in many countries domestic grid codes impose strict requirements on the work of these sources in the case of a short circuit. Regulations on low‐voltage fault ride‐through (LVFRT) require that the RES support the work of the EPS during disturbances. In such cases, the RES can be damaged by prolonged duration of short circuit currents. Application of superconducting fault current limiters (SFCLs) protects the RES from the effect of short circuits and improves LVFRT capability. This study describes simulation studies showing the impact of the SFCL on the values of the short circuit current and the voltage at the RES terminals for different short circuit locations. Research results have confirmed a positive impact of the SCFL on the RES during disturbances.
