Development and Testing of Protection Scheme for Renewable-Rich Distribution System

Brahma, Sukumar B.; Ranade, Satish R.; Elkhatib, Mohamed E.; Ellis, Abraham E.; Reno, Matthew J.

As the penetration of renewables increases in the distribution systems, and microgrids are conceived with high penetration of such generation that connects through inverters, fault location and protection of microgrids needs consideration. This report proposes averaged models that help simulate fault scenarios in renewable-rich microgrids, models for locating faults in such microgrids, and comments on the protection models that may be considered for microgrids. Simulation studies are reported to justify the models.
