A microgrid is a discrete energy system consisting of distributed energy sources (including demand management, storage, and generation) and loads capable of operating in parallel with, or independently from, the main power grid. A segmentation of microgrid, ie a creation of multiple islands or sub-microgrids must be supported by microsource and load controllers under these circumstances, problems related to selectivity (false, unnecessary tripping) and sensitivity (undetected faults or delayed tripping) of protection system may arise.
