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.

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

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

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

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

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)

• 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 years and previous
  years data be available on line
• Suggest previous three years data be available
  off-line
