A Mul&-‐Scale Design and Control Framework for Dynamically Coupled Sustainable and Resilient Infrastructures,
with Applica&on to Vehicle-‐to-‐Grid Integra&on (EFRI – RESIN, Award Number: 0835995)
People PI: Jeffrey Stein [[email protected]] (University of Michigan) Co-‐PIs: Zoran Filipi [[email protected]], Gregory Keoleian [[email protected]], Huei Peng [[email protected]] (U-‐M) and Mariesa Crow [[email protected]] (Missouri University of Science and Technology) Par&cipa&ng Inves&gators: Duncan Callaway [[email protected]] (Berkeley), Hosam Fathy [[email protected]] (U-‐M), Carl Simon [[email protected]] (U-‐M), John Sullivan [[email protected]] (U-‐M) and Jing Sun [[email protected]] (U-‐M)
Good and frequent communicaRon and interacRon is considered key to our project's success and this occurs primarily at biweekly research meeRngs. At each meeRng a presentaRon is given by of one of the task area researchers. This allows team members see what each task is focused on, what their results mean, how it affects all tasks projects, and the potenRal for task integraRon. Offsite team members aVend via teleconferencing and receive slides via email. Offsite team members can visit U of M as oWen and for as long as they would to because office space has been made available for them.
Research Objec&ves Project Descrip&on
Enabling Poten&ally Transforma&ve Results Status of Research
Managing a Mul&-‐Disciplinary and Mul&-‐Ins&tu&onal Project
Vehicle to Grid (V2G) may poten&ally improve resilience by: -‐CreaRng a redundancy of power sources and flow paths. -‐Improving grid integrity to disturbances through energy storage. -‐Decreasing the load through peak shaving and reacRve power.
V2G provides sustainability through increased energy storage: -‐Allowing the grid to beVer absorb renewable electricity. -‐RedistribuRng power demand over Rme in both infrastructures. -‐Possibly decreasing use of expensive grid peaking units.

Personal TransportaRon Infrastructure
Electric Power Infrastructure
Mul&-‐Role Intermediaries (MRIs) An infrastructure’s sustainability and resilience oWen depend on how strongly coupled it is to other infrastructures through the exchange of commodiRes, resources, services, or informaRon. This exchange oWen takes place through MulR-‐Role Intermediaries which may be organizaRons, individuals or intelligent devices.
Plug-‐in hybrid electric vehicles are an important MRI because they couple the personal transportaRon infrastructure with the electric power infrastructure. This is the project’s test bed applicaRon.
