In the context of the API documentation, SID is usually used to denote the "subsystem id." A subsystem is a collection of buses within PSSE that you're doing special work or analysis on. You can define upto 4 subsystems in PSSE, with valid values of SID being between 0 and 3. You can define a subsystem based on area, zone, voltage, and/or owner. You can find a good example here:

For more information and a nice wrapper, look here:

** Note: This page says the limit is 12 subsystems numbered 0 to 11. That is not what the documentation for v32 says. I'm not sure where the number "12" is coming from.
