This paper presents the results obtained from a directional overcurrent protection scheme simulation and modeling process, in which communications reduced the number of protections necessary to guaranty robustness and back-up system response. In order to compare this scheme with others found in the review, the related literature was characterized and classified, so as to reveal the importance of communications, as well as opportunities for improvement, so as to reduce tripping times and relay numbers, as described in the proposed scheme. In addition, both a digital relay protection adaptation and a new protection scheme are presented. Finally, microgrid model characteristics, protection parameters, and MATLAB/SIMULINK implementation are presented together with their respective outcomes.
