Retrieve Inter-Area Transfer data by Area

asked 2018-12-06 15:52:12 -0500 gravatar image

Is anyone aware of an API function to retrieve a list of all Inter-Area transfer data (From Area, To Area, ID, MW) by area? I can retrieve inter-area transfer MW by using TRXDAT, but I have to know the from area, to area, and transfer identifier. But I wasn't able to find anything in the PSSE Documentation for subsystem data retrieval.

psspy.inta() mentioned above and the macro-recording functionality of psse are good points.

Additionally, in the V34 documentation the API manual has a few functions under Chapter 8.23 (Area subsystem data retrieval) that you should look at.

  • psspy.aareareal is a function that has various options for returning area interchange values.
  • psspy.aareaint could return you a list of all area numbers. You could combine this function, the array it returns, and the TRXDAT function you mentioned to write a loop that iterates over combinations of existing areas and determines the transfer between those areas.

Finally, you could just do a simple psspy.list() function, and be sure to specify the option so that you output "area interchange data" or "inter-area transfer data"-- obviously doesn't return you values, but would allow you to observe what is going on.

as a rule of thumb; if you do not find an API in the manual, try executing PSS/E to obtain what you want and record what you are doing using *py. If you were to do this you will notice that you have two choices:

psspy.inta(number,number) psspy.area_zone(number,number)

where if number, number is 0,1 the report is for all areas
