  1. Using Smart Grid Technology to Integrate Renewable Resources Peter Christensen October 24, 2011 PNNL-SA-83093

  2. PNNL smart grid “tools” • Supply side: • Visualization tools • Grid analytics • Demand side: • Grid friendly appliances • Transactive control • Frequency responsive load

  3. Question What do a water heater and an EV have in common? They store energy!

  4. Frequency regulation example With Grid Friendly™ electric vehicle and water heater charging

  5. Replacement Reserve Contingency Operations Supplemental Reserve Frequency Responsive Spinning Reserve Normal Operations Load Following / Energy Imbalance Regulation Voltage Control 0.1 1 10 100 TIME (MINUTES) Ancillary services

  6. What’s the value? Valuation of power system regulation service provided by residential water heaters (value per water heater, per year) 7

  7. Integrating renewables If 10% of all vehicles in the Pacific Northwest were EVs… …all the balancing requirements to enable integration of wind resources would be met!

  8. Benefits of frequency response • Autonomous • requires no smart meters, communication systems, or centralized control • Fast • relatively instantaneous • Economical • replaces existing regulation services capacity • Clean • uses demand as a resource!

  9. Challenges to frequency response • Measuring and accounting for response • Sharing the value among all stakeholders • Current regulatory policy and industry structure does not enable this technology

  10. Key take-away points • Demand Response Technology enables the use of demand as a resource to integrate renewables • Enormous potential value for all stakeholders • The technology is ready – now let’s enable it!
