Fault current limiters (FCLs) are one class of solutions to cope with the upcoming challenges in microgrid protection. Considering high penetration of distributed generations (DGs) in microgrids, the necessity of designing cheap and effective FCL is getting higher. This paper attempts to fill this gap by proposing an embedded FCL operating based on modifying the secondary control of DGs. As this method is designed for fourwire system, besides cost-effectiveness, it has independency and

... ty to only limit the fault current of DG. In order to validate the proposed method, different types of faults are examined through an extensive simulation study.
