Presentation Transcript

  1. Market Interface Committee Renewable Integration Issues

  2. Introductions • Versify • Focused on software applications and tools in two areas of the power industry • Core competency in highly scalable data collection, processing, analytics, and reporting systems • Partnership with CECD • Constellation Energy Control & Dispatch (CECD) • A decade of experience Successfully implemented 30 Control Areas/Balancing Authorities in 5 NERC Regions • Currently operates 11 Balancing Authorities (including GWA) with NERC and regionally certified personnel • International Demand Response center for implementation, dispatch, ISO interface, and reporting

  3. Agenda • Wind Integration Challenges • CECD Solution provider • Example: Glacier Wind • AGC and Reserve Requirements • Compliance Management and reporting • Market Tools & Techniques • Closing

  4. Wind Integration Issues • Wind variability  Volatility • Wind Facility Complexity • Forecasting accuracy • Long Term • Short Term • Intra-hour balancing

  5. CECD Solution CECD Solution

  6. Integration Desk (I-Desk) • Increased focus and granularity to manage volatility • Integration of wind with multiple sources of AGC • Implement dynamic ties in new, compliant ways • Utilization of software and systems that are “fine tuned” for unique requirements

  7. CECD Toolset Dedicated Integration Desk (“I-Desk”) • Trained Staff • EMS • Near Term Forecasting Tools • Data management processing/reporting (Versify)

  8. Glacier Wind Glacier Wind

  9. Glacier Wind Glacier Wind Project (GWA) • Located in Cut Bank, Montana • 106.5 MW Capacity (71 turbines) • GWA began operating as BA on Oct 15, 2008. • First wind-only Balancing Authority.

  10. Operational Requirements • AGC Contracts from 3rd party sources • Operating Agreements with Adjacent BA describing normal and emergency operations • Contingency Reserve Requirements in place

  11. AGC & Reserve Requirements • BA Responsibility to maintain AGC capacity for: • Frequency Bias response, CPS, 5% Operating Reserve margin • Additional AGC to balance wind variability • Wind profile case study • Deviation from forecast used to define additional AGC requirement

  12. Tools & Techniques • Executed Regulating Reserve Services Agreement w/ third party. • AGC and Dynamic Schedule • Provides significant ability to balance energy at any time • GWA will participate in ACE Diversity Interchange (ADI) to share ACE signals with BA’s and balance with each other. • Allows for adjustment through ACE sharing with other participants • Wind forecasting tools • Worked closely with adjacent BA Northwestern Energy • NWPP reserve pool membership for contingency reserves

  13. Closing • Focus on granularity to manage reliability • Responsibility as a BA is to make sure energy flows • Potentially scalable solution as gain knowledge and experience Dave Ippolito, Versify dippolito@iversify.com JT Thompson, CECD jt.thompson@constellation.com
