  1. SSG-WI System Model Data Requirements [PART 1] September 5, 2002 Las Vegas, NV

  2. ….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)

  3. 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”

  4. 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

  5. Data Types – cont. • Constraints • Interfaces – lines or collections of lines • Nomogram • Control Area – to – Control Area

  6. 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?

  24. 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

  25. 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
