To develop and evaluate a methodology for assessing how battery electric bus fleets enhance the resiliency, critical load service, and protection of microgrids during islanded operations.
Modeled an operational framework for mobile energy resources and evaluated it on an existing 20 MW-class microgrid integrated with 20 battery electric buses (324 kWh capacity and 80 kW charge/discharge rate per bus, totaling 1.6 MW and up to 6.48 MWh).
Assessed 'Mobility Services+' deployment schemes, analyzing the fleet's capacity to power internal critical loads, support external community infrastructure, and supply blackstart power using parked and transit-recalled buses.
Demonstrated that the battery electric bus fleet can continuously support a microgrid emergency control center for at least 16 hours during an outage.
Achieved a 100% probability of successfully serving as a blackstart resource following a prime generator trip by coordinating parked and route-recalled buses.
