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
