Acting on this Information Will:Enable active participation by consumers
Anticipate & respond to system disturbances (self-heal) Accommodate all generation and storage options
Operate resiliently against attack and natural disaster Enable new products, services and markets
Optimize asset utilization and operate efficiently Provide power quality for the digital economy
Characteristics of the Smart Grid:
Prague, 8-11 June 2009
Smart Grid Demonstrations• Integration of
Distributed Energy Resources (DER)
• Deploying the Virtual Power Plant
• Several regional demonstrations– Multiple Levels of
Integration– Multiple Types of
Distributed Energy Resources & Storage
• Leverages Information & Communication Technologies
Prague, 8-11 June 2009
Smart Grid Demonstration Approach
• Integration of DER with Utility Operations
• Ensure Interoperability of DER– Demonstrating use of common language to exchange information with
distributed resources from various manufacturers
– Multiple use of communication and metering infrastructure for control, measurement & verification of the dispatchable resource

Demonstrations address range of characteristics and applications
• Regional characteristics – Weather– Regulatory / Market– Availability of Renewable Generation & Storage
• Customer / Load characteristics – Residential, Commercial, Industrial
• Distribution system characteristics – Rural, suburban, urban overhead and underground systems
• Communication Infrastructure available– Public (internet, cellular) – Private (AMI, licensed)

Key ObjectivesDefine information models and communications interfaces
– All Levels of distributed resource integration (home, enterprise, market)
Develop application guidelines, integration requirements and standards for distributed resource integration.
Field Assessments to:– Understand required systems and technologies for
distributed resource integration
Verify Smart Grid business case assumptions – Describe costs and benefits associated DER Integration
