From each AC we should receive the following:

1. Area Specific power flow data2. L&R spreadsheet3. Any dynamic model changes/updates4. Any tie line changes (must be coordinated!!!)5. List of significant changes6. Any additional info that will help with base case

compilation

Creating a Raw Case

Contains raw data for the following:

1. Branches2. Transformers3. Line connected shunts4. DC lines (Bus, Line, DCC)5. Transformer impedance tables6. Interface data (Paths)7. Branch interface data8. Zones9. Owners10. Area Interchange

Power Flow Solution and Data Checking

• Island check• Tie line check• Edit table checks

– Mustfix.p– Checks.p– svdsnap.p– Pathmoni.p– Tappfixer.p– Dchk– Baseloader.p– InsertTurbine.p

• Overload check (Line & Path)• Solution check

– InsertLID.p– InsertGENID.p– FillRatingsPSSe.p– DCINTMT.p

• Replog– PowerWorld

• PTI Conversion

The Master Dynamics File (MDF)

1. Models2. Updates in PSLF format3. Temporary vs. permanent changes4. Motor load modeling 5. Condenser and pump check6. Unused models7. Composition load models

Running and Plotting

• A no-disturbance run• The alldyns.p

disturbance routine– Ringdown– Double Palo Verde

Outage– Loss of PDCI– Post-transient solution

– Disturbances• Metcalf-Moss landing,

Tesla-Metcalf• Comanche-Daniels Park• Colorado River – Red

Bluff• Hells Canyon –

Brownlee

• N-0 Overloads-Operating cases

16


Plotting

• Plotting the channel file

1. Searching for the largest deviation (spread)

2. Plotting parameters

17


• Types• Submitted in EPCL, EPC, .m, or by list• MUST be made to review case• Changes to tie lines must be coordinated• Extensive data changes
