MicrogridsforEnhancedResilience,Reliability,Economics,andEfficiency
1
Resiliency: crucial recovery centers during major disruption eventsReliability: mitigate utility service interruptionsEconomics: arbitrage, demand management, controllable loadsEfficiency: renewables integration, combined heat and power
Path forward: seamless grid communication to enable grid services and providelow-cost solutions for grid management and damage mitigation

Scope§ Develop and demonstrate practical use of resilience
metrics for coordinated operation; design to minimizeoutage and financial losses
§ Leverage rotational and virtual inertia of microgridassets including hydro, diesel, energy storage, andµPMU-based sensing to enhance resilience of theoverall distribution network
§ Rapidly prototype controllers as HIL and conductcyber-vulnerability testing in a real-time cyber-secureenvironment
§ Field validate increasing resiliency of the distributionsystem by leveraging resources from multiplenetworked microgrids
