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
