Summary

Microgrids offer a number of interesting and valuable capabilities along with challenging engineering questions: -Voltage and frequency stability:  Does the microgrid include the correct mix of real and reactive power sources and sinks?  How fast must non-critical loads be shed to maintain stability during unintentional islanding? -Protective relaying performance:  How fast must faults be cleared from the islanded microgrid to prevent microgrid collapse?  -Ground source arrangement:  Where are the microgrid ground sources and how do they impact performance? -Arc flash hazards:  How are they different in islanded operation and what can be done to mitigate increased flash hazards? This presentation describes tools, solutions, and lessons learned.
