Parallel Flow Visualization — Data Requirements —

1. Parallel Flow Visualization— Data Requirements — Jim Busbin Chairman, IDC Working Group NERC ORS Meeting Toronto, Ontario September 23-24, 2009

2. Parallel Flow Visualization Presentation Topics — • Purpose • Background • Data Requirements • Data Archive • IDC Change Order 283, Revision 2

3. Parallel Flow Visualization Purpose

4. Parallel Flow VisualizationPurpose The Purpose Statement from the Parallel Flow Visualization SAR states: The requested enhancements to the TLR procedure in the Eastern Interconnection will improve the wide-area view of Reliability Coordinators (RCs) such that they better understand the current operating state of the bulk electric system and will result in the assignment of relief obligations during periods of congestion that are more representative of those actually contributing to the congestion.

5. Parallel Flow Visualization Background

6. Parallel Flow VisualizationBackground May 6 NERC ORS Meeting in Indianapolis, IN. IDCWG was directed to: • Identify the minimum data set required to achieve the required calculations by the September 2009 ORS meeting • Identify the required changes to the IDC to identify the GTL impacts • Recommend a vendor to perform the GTL calculations for all EI RCs • Determine, in cooperation with the vendor, the GTL calculation methodology • Identify to the ORS any additional items that are required to incorporate GTL impacts • The IDCWG should target having proposed recommendations to the ORS for the November 2009 meeting

7. Parallel Flow VisualizationBackground IDCWG has discussed and identified requirements to support Parallel Flow Visualization – we continue to evaluate these requirements June 3-4 IDCWG Meeting: • Discussed charge given by ORS • Initiated identification of requirements July 8-9 IDCWG Meeting: • Meeting held to discuss Parallel Flow Visualization • Identification of requirements continued August 18-19 IDCWG Meeting • OATI asked to revise Change Order 283 to include requirements identified in July meeting – this modification will become Revision 2

8. Parallel Flow Visualization Data Requirements

9. Parallel Flow Visualization Data Requirements — Introductory Notes • Reference: “Generation-to-Load Reporting Requirements” whitepaper, January 2, 2009 • Generation-to-load flows will be calculated by one vendor. Raw data used in the calculation will be submitted to the vendor • Frequency of all data submission will be every fifteen minutes unless otherwise noted by (♣). • Data will be submitted to reflect current-hour conditions and a projection of peak next hour conditions. To be clear, each data submission will contain data for the present hour and also for the next hour

10. Parallel Flow Visualization Data Requirements — Categories • Load and Losses • Real Time Load Magnitude and Distribution • Generation Output • Real-Time Output vs. Static Values • Flowgate Flows • Provides Error Checking Capability • Topology Updates • Provides More Frequent Update of Topology and • Additional Data

11. Parallel Flow VisualizationData Requirements Load and Losses — • Total Real-Time BA Load • Geographic Zones • Conforming / Non-Conforming Zones • Individual Bus Loads • and Total for BA • Real-Time Losses for Total BA • Projection of Next Hour Total Peak BA Load • Geographic Zones • Conforming / Non-Conforming Zones • Individual Bus Loads • and Total for BA • Projection of Next Hour Losses for Total BA

12. Parallel Flow VisualizationData Requirements Generation Output — • Real-Time Generation Output • Output for Each Generating Unit Shown in Model • Net of Auxiliary Equipment / As Modeled • Total Real-Time Generation Output for BA • Projected Next Hour Generation Output • Output for Each Generating Unit Shown in Model • Projected Maximum Output of Unit in Next Hour • Net of Auxiliary Equipment / As Modeled • Total Projected Next-Hour Generation Output for BA • Generating Unit Real-Time Upper and Lower Normal Limits • Joint Ownership Identification ♣

13. Parallel Flow VisualizationData Requirements Flowgate Flows — • Actual real-time flow on each active flowgate monitored element shown in the Book of Flowgates • Projection of next hour maximum flow on each active flowgate monitored element shown in the Book of Flowgates Projection of Next Hour Losses for Total BA • Actual real-time flow on each active flowgate contingency element shown in the Book of Flowgates • Projection of next hour maximum flow on each active flowgate contingency element shown in the Book of Flowgates • Un-accounted for usage will be identified and calculated as the difference between real time flows and the summation of calculated tag impacts, market flows and generation-to-load flows

14. Parallel Flow VisualizationData Requirements Topology Updates — • Increase frequency of IDC update from SDX and matrix calculation to every fifteen minutes • Outage updates submitted to SDX every fifteen minutes

15. Parallel Flow VisualizationData Requirements Additional Data — • Control Device Data – Scheduled and Actual Flows, Real-Time and Projected Next Hour: • Phase shifting transformers • DC lines • Variable frequency transformers • Dynamic Schedules – Actual and projected next-hour flows • Identification of pumped storage hydro units ♣

16. Parallel Flow VisualizationData Requirements Additional Data — • (NAESB / United States) – Designated Network Resource (DNR) generating units/plants • (NAESB / United States) – DNR capacity • (NAESB) Assignment of priorities for generation-to-load (7-F versus 6-NN) • Net scheduled interchange • Net actual interchange • Individual actual tie-line flows

17. Parallel Flow Visualization Data Archive

18. Parallel Flow VisualizationData Archive • Impact archive will be added that saves • Tag impacts • Market flows • Generation to load flows • Un-accounted for usage • Real-time flows by flowgate • Archive to run around the clock – not just when a flowgate is in TLR • Suggest current calendar year’s and previous year’s data be available on line • Suggest previous three year’s data be available off-line
