Reviewer 2 Report

In this study, an algorithm is proposed to face the fault that modifies the SOGI-FLLs gain parameters in order to achieve a better transient response with a reduced perturbation in the estimated frequency. The algorithm uses the SOGI’s error and its absolute value to detect the fault and change the SOGI-FLL gains during the fault.  This work is interesting. However, the writing should be improved before the acceptance for publication.
