UC San Diego Smart Microgrid

  1. 1. UC San Diego<br />Smart Microgrid<br />John Dilliott, <br />Manager, <br />Energy & Utilities<br />May, 2010<br />
  2. 2. With a daily population of over 45,000, UC San Diegois the size and complexity of a small city.<br />UC San Diego Operates a 42 MWpeak Microgrid<br />As a research and medical institution, we have two times the energy density of commercial buildings<br />Campus Quick Facts<br />11 million sq. ft. of buildings, $250M/yr of building growth<br />Self generate 80% of annual demand<br /><ul><li>30 MW natural gas Cogen plant
  3. 3. 2.8 MW of Fuel Cells contracted
  4. 4. 1.2 MW of Solar PV installed, additional 2 MW planned</li></li></ul><li>A History in Climate Research<br />
  5. 5. New Technology in Old Buildings<br />Continue to be a Leader in Carbon Reduction and Energy Efficiency<br />Even with increased energy intensive activities and growth, facility retrofits have decreased energy consumption per sq. ft.<br />Completed $60M in energy retrofits reducing energy use by 20% or 50M kWh/yr, saving UCSD $12M annually.<br />300,000<br />1999-2000<br />280,000<br />2007-2008<br />Current Program is a three year $73M investment that will produce $7M in annual savings<br />260,000<br />240,000<br />220,000<br />2009-2014: Invest $66M <br />(49+17) to achieve <br />35M kWh/hr reduction<br />200,000<br />BTU/SF<br />
  6. 6. Existing Infrastructure<br />Centralized Heating & Cooling<br />High Voltage Substation<br />Digital Controls<br />Thermal Energy Storage <br />Cogeneration<br />2009-2014: Invest $66M <br />(49+17) to achieve <br />35M kWh/hr reduction<br />BTU/SF<br />
  7. 7. Renewable Expansion<br />1.2MW Solar PV<br />2.8 MWmethane powered Fuel Cell.<br />1.8 MW Advanced Energy Storage System<br />8<br />
  8. 8. Typical Load Profile - Week<br />
  9. 9. Typical Load Profile - Day<br />
  10. 10. Typical Load Profile – Price Breakdown<br />Shaping costs<br />$0.015/kwhr<br />Spot Peak Power $????/kw-hr<br />Off Peak Power $0.055/kw-hr<br />Block Peak Power $0.12/kw-hr<br />Off Peak Power $0.055/kw-hr<br />On site PV$0.17/kw-hr<br />Renewable Fuel Cell Power $0.127/kw-hr<br />Cogenerated Power $0.065/kw-hr<br />
  11. 11. UCSD’s Perspective on Energy Storage<br />Energy storage is the missing link and enabler technology<br />UCSD is pursuing 4 energy storage projects<br /><ul><li>Distributed Energy Storage
  12. 12. Frequency Regulation
  13. 13. Optimized Thermal Energy Storage
  14. 14. Grid to Vehicle Integration</li></ul>UCSD has issued a $3.4M RFP for 2 MW<br />/ 10 MWH of Advanced Energy Storage,<br />and bids are due December 15, 2009<br />The result will be a smart microgrid that is nationally replicable and scalable<br />
  15. 15. UCSD’s Perspective on Energy Storage<br />
  16. 16. UCSD’s Perspective on Energy Storage<br />
  17. 17. UCSD’s Perspective on Energy Storage<br />
  18. 18. Creating a Green Smart Microgrid<br />UCSD’s Microgrid will embody all 7 Smart Grid Functions envisioned by the Energy Independence & Security Act, 2007<br />RESCO $2M program with CA Energy Commission will deploy:<br /><ul><li> Advanced master controller for microgrids
  19. 19. Siemens scheduler platform for dynamic market signals allow optimization of storage and supply
  20. 20. Real time data acquisition for analysis</li></li></ul><li>Developing a Micro Smart Grid<br />Creating a GreenSmart Microgrid<br />Comprehensive Metering<br />2007 Demand Response<br />Electric and Thermal Interval Meters reporting to Central Database <br />http://energy.ucsd.edu<br />
  21. 21. Collaboration with Faculty Innovators<br />Energy Storage Controller for High PV Penetration<br />16 advanced weather stations across campus provide dense network of microclimate data<br />Automated Cloud Detection Alert has the potential to Manage Energy Storage in Real Time<br /><ul><li> Automated cloud detection and alert
  22. 22. Energy storage control based on PV output drop
  23. 23. Decrease PV ramp rates from 50 kW/sec to 1 kW/sec
  24. 24. Avoid voltage flicker and power outages</li></li></ul><li> Thank You<br />UC San Diego is a global leader in research and proto-typing solutions to climate change, renewable energy, and sustainable systems<br />
