ComEd announced today that it, "successfully conducted a test proving that the Bronzeville Community Microgrid can keep power flowing in the event of an emergency."
The “simulated islanding” test checked the resiliency of the microgrid by mimicking events that have the potential to affect power delivery, including major weather events or cyber security or acts of terrorism, ComEd said
The set of tests ComEd conducted demonstrated the microgrid’s ability to provide power in island mode while drawing upon distributed energy resources (DERs), including battery energy storage and solar photovoltaic PV, to serve customers within the microgrid footprint.
During the test, a portion of ComEd’s electric grid operated from distributed energy resources to demonstrate the capability of the microgrid to serve the customers in its footprint. The residences, businesses and public institutions served by this circuit in Bronzeville received power from a locally sited battery energy storage system, solar energy and mobile generation. Customers experienced no difference in the level of service during the test and were not separated from the system at any time.
The microgrid will ultimately connect with an existing microgrid on the campus of Illinois Tech
