Example Transcript of Security Evaluation

 

//All comments follow the "//" (double backslash)

//This is a run through the SEEKS--PSAP--SEEKS procedure

// Make sure that both "SEEKS.EXE" and "PSAP.EXE" are in the same directory

//Open "SEEKS.EXE" follow the below transcript





Please choose :(1) build the system from scratch:

               (2) load an existing system that is in standard format: 2



Please input the filename: demo2000.txt



There are 5 buses, 6 branches, 3 generators, and 3 loads in your grid.







1. Open PSAP.EXE.

2. In PSAP.EXE: a) Read pf.txt.  b) Solve.  c) Write pf.txt

3. Go back into SEEKS.EXE, type anything to continue.







// Open "PSAP.EXE"
