SSG-WI System Model Data Requirements

[PART 1]

September 5, 2002

Las Vegas, NV


From pacificorp s 7 31 02 presentation

….from Pacificorp’s 7/31/02 presentation

  • Set up a complete data set for Y2008: generators (capacity, costs, availability); loads by control area (annual energy, monthly maximum demand and hourly demand profile); and transmission network (a complete WSCC system or other as specified by WG)


Data use confidentiality

Data Use/Confidentiality

  • Per previous meeting, the SSG-WI database needs to be public

  • Per PacifiCorp: Database needs to be built from the “ground up”


Data types

Data Types

  • Load Flow – WSCC

    • Network Data – busses, lines, transformers, generators

  • Resource Data

    • Dispatchable – thermal units

    • Non-dispatchable – hydro, wind, solar

    • Fuel - cost

  • Load Data

    • Load distribution (within Control Area – per load flow)

    • Load Shapes (by Control Area)

    • Load Forecast


Data types cont

Data Types – cont.

  • Constraints

    • Interfaces – lines or collections of lines

    • Nomogram

    • Control Area – to – Control Area


Couger lowest common denominator

Couger Lowest Common Denominator

  • Control Areas

    • Load Shape

    • Unit Commitment

      does not appear to have multi-owner capability

  • Primary Decision Point for WG – how many control areas?

Data coordinators

Data Coordinators

  • Network:

    • Load Flow – WSCC/WECC

    • Decide on which case to use

    • Secure WECC permission

    • Data Scrubbing

  • Load Forecasts

  • Generators

    • Heat Rates and Fuel Price: where do we get this from public sources? What source do we rely on?

  • Load/Resource Profiles – EEI Format

    • Each Control Area

    • Non-Dispatchable Resources

  • Area/Regional Contraints


Load flow data scrubbing

Load Flow Data “Scrubbing”

  • Network Elements:

    • Multi-segment lines – series compensation

    • Zero (or extremely low) impedance segments essentially bus ties

    • Phase shifters not set to regulate
