Integrating Demand Response Efficiency Renewables and Smart Grid

Integrating Demand Response, Efficiency, Renewables and Smart Grid Overview of Open. ADR May 4, 2011 Sila Kiliccote Deputy, Demand Response Research Center Environmental Energy Technologies Division Lawrence Berkeley National Laboratory

Overview of the Presentation § § Overview of the Research at Demand Response Research Center Overview of Automated Demand Response and Open Automated Demand Response (Open. ADR) specification Results from Key Implementations and Pilots Conclusion

DRRC’s Original Vision Statement - 2004 • Efficiency and demand response fully integrated under a unified default tariff / incentive structure. 1 § Demand Response, like Efficiency a condition of service. § All customers, all load participates. 2 3 § Major appliances come “DR Ready” from the factory. § All buildings are “DR Enabled”. Full automated system integration between your generator, distributor and customers.

DRRC Research – In Process Rationalizing Open. ADR to Other Industry Standards q q Open. ADR is the only existing open data model to bridge communications between utility and control systems in commercial and industrial facilities. Open. ADR “Price Mapping Demonstration Project” will extend DR capability into small commercial and residential. 9

DRRC Research Lessons Learned Automation Open Data Models Price and Reliability Signals q Allows DR to be a dispatchable resource (wholesale and retail DR). q q Improves DR reliability, predictability, and value (summer / winter ). Increases customer participation and reduces response cost (transparent retail to wholesale DR conversion). q Simplify and reduce cost of DR (embedded clients). q Creates interoperability among customer systems. q Create interoperability between wholesale and retail systems. Allows customers to choose level of response and how to enable DR strategies (increases DR response). q Provides ability to embed automation in customer control systems (increases DR reliability, customer participation).
