1. Integration of Variable Generation Task Force (IVGTF): Status
Warren Frost (Presented by John Kehler)
Chair, IVGTF
NERC Operating & Planning Committee
June 4-5, 2008
Toronto, Canada

2. IVGTF Scope The Task Force will prepare The document will include:
A concepts document that includes the philosophical and technical considerations for integrating variable resources
Specific recommendations for practices and requirements, including reliability standards, that cover the planning, operations planning, and real-time operating timeframes
The document will include:
Planning timeframe issues, such as contribution to capacity margins modeling requirements to test system reliability and planning transmission
Operational Planning and Real-time operating timeframe issues, including forecasting, short term adequacy, operator awareness, interconnection frequency control, operating reserves, and wind power management
Review NERC Standards for any gaps
Review of future developments including storage and other technologies
Conclusions and recommendations.

3. IVGTF Status Report With 50 participants, 5 Subgroups formed
Introduction
Characteristics of Variable Generation
Planning and Technical Impact
Operational Planning & System Operations
Other and Future Considerations
Leadership Team Drove first Draft (250 pages)

4. IVGTF Status Report First Face-to-Face meeting held
Identify consistent themes
Focus on the impacts and implications - “what” not the “how to”
Develop key conclusions/recommendations
Review comments on each section
Identify overlaps and gaps
Excellent participation and shared learnings
A key observation is technical barriers for large scale wind integration can be overcome. The challenges are policy and costs.

6. Examples of the Themes and Common Threads
Uncertainty
Variable resources lead to uncertainty in time frames of minutes from real time operation to years away from real-time operation
Transmission
Planning transmission with variable resources connecting to the grid
Consideration of planning transmission with the potential of large amounts of distribution connected generation connecting
Flexibility
Variable generation will require flexible resources
Examples of flexibility can be in future development of new conventional generators, quicker access to generation across the interconnection, increasing balancing area size, demand side options, storage, etc.
Efficiency and Reliability
Wind power forecasting for example is one area where reliability and efficiency will benefit
Equipment Performance
Wind power facility equipment standards will identify the requirements and performance for items such as LVRT and voltage regulation.
Decisions made today on equipment performance we will live with for the life of that facility

7. IVGTF Next Steps Next Steps include:
Develop page report with key themes & identifying recommendations
Remainder of research will be contained in appendix that will provide an excellent reference for industry
