  1. Maryland Clean Energy SummitHyattsville, MD October 15, 2013 Princeton University’s Microgrid Operation During Hurricane Sandy Thomas A. Nyquist, PE tnyquist@princeton.edu

  2. System Design • Distributed base-load generator(s) • Ability to run isochronous • Underground utility distribution • Multi-fuel Capability • Load-shed capability • Black start diesel

  3. Thank you

  4. Major Campus Needs During Sandy • Long term research samples need to be kept frozen • Experiments running under deep vacuum need to continue operating • MRI machines cannot quench • Computer systems for research and administration need to remain operational • Vivariums need to maintain environmental conditions • 1000 students on campus need housing and food • Campus workers need food and shelter • Town emergency workers need food

  5. Campus Power During Hurricane Sandy

  6. Need good personnel to handle switching • Staff to selectively load shed • Commission fully • Repeat testing Testing and Training

  7. Lessons Learned • Solar PV – Did not use • High wind dangerous for personnel needed for switching. • Employees have personal problems during storms or cannot travel during or right after storm. • Prepare for an extended outage – people on site get tired.

  8. Community Members Perceptions • Researchers – labs had power and no research was lost • IT – Computers and network stayed up • Senior Administration – things worked out well • Senior Administrator that also went thru Hurricane Katrina in New Orleans and the Northridge earthquake – Sandy not so bad • Town person – why did the utility keep the University’s lights on and not mine? • Town person – appreciative that university opened buildings for food and power. • Essential Princeton Staff – tired, but rightly proud of their response. • Student – “what no omelets?”
