In microgrid distribution systems, irregular system fault characteristics (with respect to grid-connected mode) and the variability of power flow direction, present challenges to developing a robust and reliable protection scheme that will effective response in both grid-connected and grid-isolation mode. The following investigation captures a meshed network from a larger urban low-voltage (LV) network system in the service area of Consolidated Edison Company of New York (ConEdison), a United States (US) utility that has sufficient customer supplied generation to act as a standalone microgrid. The investigation assesses the viability of differential protection schemes. Protection response has been reviewed with respect to real world application; including, benefits and limitations of selectivity, sensitivity and reliability.
