I am new to PSSE and have been looking thorough the API documentation in search of a method that will take a bus number as argument and return all the buses which are connected to it. The closest I have got is using NXTBUS, but from what I can tell it will only give me one of the adjecent buses and then move on down the line. I'm wondering if maybe I have to get all the branches first and then check what buses are connected to given branches?

If anyone knows of a way to fetch all buses connected to a specific bus that would be amazing.

You have to call nxtbrn in a loop until there are no more branches connected to ibus. See example below:

tobuses,ckts = [],[]
ierr = psspy.inibrn(ibus,2)
while ierr==0:
    ierr, jbus, ickt = psspy.nxtbrn(ibus)
    if ierr==0: 

List tobuses will contain the to bus number of all branches and 2W connected to ibus. List ckts contains the id's.
