2 Grid Integration Objectives Grid Integration of end-uses and electrical vehicle fleets represents a key efficiency and energy security objective for the Federal and State Agencies. The Grid Integration Group (GIG) develops the technologies and tools to: 1. facilitate dynamic interaction between grid operators and energy consumers; 2. support the grid integration of intermittent renewable sources; and 3. foster the participation of distributed energy resources.

5 OpenADR and Interface with End-Uses Provides non-proprietary, open standardized DR interface (XML) Allows electricity providers to communicate DR signals directly to existing customers. Common language and existing communications (e.g., Internet). Enables protocol interoperability Secure architecture for point-to-point, decentralized markets.

Fully integrated end-to-end systems demonstrations using demand-side assets for grid integration: 1. Load as a regulation resource: V2G demonstration 2. Load as spinning and non-spinning reserves: Participating Load Pilot 3.

7 Systems Interoperability: Demonstration & Research Conduct research and support open and related automated DR technologies, end-use devices, and their integration with the electric grid. Key interoperability concepts for DR communications Structured for current (pointto-point communications) and for future (de-centralized communications) DR markets Energy transactions and customer participation in multiple markets End-to-end integration of open communications with demand-side resources (B2G, V2G, etc.) * 6
