Distributed Intelligent Automated Demand Response (DIADR)In Sutardja Dai Hall Jason Trager
Introduction • Demand response: Turning things off instead of turning power plants on • Need for Automation • Need for Distributed Intelligence • Ancillary Service • Can provide substitute for spinning reserves • … and possibly Frequency regulation
Sutardja Dai Hall • 141,000 Sq. foot mixed use office space • Half of building is Marvell Nano-lab • Staff, faculty, students • Houses the Center for Information Technology In the Interest of Society (CITRIS)
Initial Findings • Building is over-cooled and over-ventilated • Chillers are vastly oversized • Lighting often left on much of the night; occupants did not use the dimming functions. • Initial monitoring identified problems (e.g., stuck economizer damper) • Audit found many areas for conservation (e.g., ancillary LED monitors, electric adjustable desks)
RAPID AUDIT PROTOCOL (RAP) Smart phone app: scan QR code, place on appliance, enter parameters for appliance. Uses StreamFS to automatically enter database.

90-150 kW But from where?
Receptacles 125kW 90 kW Peak 90kW 44 kW 12kW
Lighting 125kW 32Kw 90kW 44 kW 12kW
HVAC / Elevators 125kW 155-380 kW 90kW 44 kW 12kW
Experiments • HVAC – preparing for hot days • Design pre cooling algorithms • 2 degrees • 4 degrees • 6 degrees • Adjust outflow water temperature • This is tricky • Affects nano-lab
Experiments • 4th floor, 7th floor DR test. Testing – light testing occurs at night • 4:15 AM, set all lights FULL • 4:30 AM, set all lights MED • 4:45 AM set all lights LOW • 5:00 AM set all lights OFF

DR Controller DR Controller N1 N2 N3 Nk
DR Controller • Should be extensible to energy efficiency • “Continuous DR” • Should pick strategies that humans would pick • Maybe better • Should learn • Critical feature of intelligence
Future work • Summer DR tests • Ongoing • Supply following load • Instead of “Demand Response” • At least one automated DR event this summer • Can we reduce more plug loads? • Computer labs shut down during DR event?
