Integration of Variable Generation Task Force IVGTF: Status

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
• 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.

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)

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.

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

IVGTF Next Steps

• Next Steps include
• Develop 30-40 page report with key themes
  identifying recommendations
• Remainder of research will be contained in
  appendix that will provide an excellent reference
  for industry
• Complete 2nd Draft
• Send to OC/PC for comment in Sept.
