Influence of
Inverter-Based
Resources
on Microgrid
Protection
Part 2: Secondary Networks
and Microgrid Protection

S

SECONDARY NETWORKS ARE DEPLOYED WHEN
exceptionally high-reliability electric service is
required for specific loads. Secondary network protection makes extensive use of the fact that the available fault currents in such systems are typically very
high. Also, most faults in secondary networks must
be isolated from both sides, which requires some
special considerations. Today, microgrids are also
being deployed as a means of increasing power system resilience on radial circuits. Many microgrids
are energized exclusively by inverter-based resources
(IBRs), either all the time or under certain operational
conditions. The protection of IBR-sourced microgrids
