Owners, Operators, and Users
2005 Energy Policy Act:
• All users, owners, and operators of the bulk-power system shall comply with reliability standards
FERC Rule
• All entities subject to the Commission’s reliability jurisdiction… (users, owners, and operators of the bulk-power system) shall comply with applicable Reliability Standards …
North American Electric Reliability Corporation (NERC)
Mission: “To ensure the reliability of the North American bulk power system”
• Formed in 1968
• U.S. Electric Reliability Organization
• Working to gain similar recognition in Canada

Integration of Variable Generation Task Force (IVGTF) Scope
The Task Force will prepare: • A concepts document: philosophical
& technical considerations
• Recommendations: practices, requirements & reliability standards
The document will include:• Planning timeframe issues
• Operational Planning and Real-time Operating timeframe issues
• Review NERC Standards for gaps
• Review of future developments: i.e. storage, EHV
• Conclusions and recommendations
Draft Summary Report prepared
Comments received from the IVGTF members
Meeting held in August
• Finalize recommendations and actions
• Editorial meeting on Summary Report
Coordination with UCTE-EWIS
IVGTF Status Report
Keeping Reliability in the Balance
Bulk power system reliability must be maintained
All generation must contribute to system reliability
Standards must be fair, transparent & performance-based
Planners & operators must understand the challenges of large scale variable generation integration
Variable generation integrated into planning & operations
New Planning/operating tool requirements described in terms of bulk power system reliability performance

What Must Change?
Planners:• Consistent methods for energy &
capacity
• Add Probabilistic Expansion Analysis
• Design Flexibility during Resource & Transmission Planning
• System Design must consider Variable Distributed Resources
• PHEVs, storage & demand response provide additional resource flexibility
• Standard, generic power flow and stability models required
• Reference Manual for Planners on how to Integrate Variable Generation.
What Must Change?
• Enhanced Grid Codes required:
Voltage & Frequency Ride-Thru
Reactive & Real Power Control
Frequency & Inertial Response
• Balancing Authorities must have Communications and Control of Variable Resources
• Write a Reference Manual for Operators on how to Integrate into Operations.
