upvote if it is correct

you can export report screen to text file using the command as follows

psspy.report_output(2, "check_all", 2) #### rending report to external txt file

psspy.report_output(1, "check_all", 2)  ### sending report to internal report screen of psse

please upvote if correct

Sir, I understand that you want to change the generation/load for a perticular subsystem either increment or decrement. this activity can be done by designing the subsystem and use the pertifuclar subsystem for increment or decrement.

    change = 100
        ############################   Automation ##############################
   psspy.bsys(1,0,[0.0, 0.12E+04],1,[4601],0,[],0,[],0,[]) # area 4601 having subsystem identifier 1
    #iniatialization and increment of generation in area 4601
    psspy.scal_2(1,0,1,[0,0,0,0,0],[0.0,0.0,0.0,0.0,0.0,0.0,0.0])
    psspy.scal_2(1,0,2,[2,3,1,1,0],[_f, change,_f,_f,_f,_f,_f])

    psspy.bsys(2,0,[0.0, 0.12E+04],1,[4101],0,[],0,[],0,[])# area 4101 having subsystem identifier 2

    # initialization and decrement of generation in area 4101
    psspy.scal_2(2,0,1,[0,0,0,0,0],[0.0,0.0,0.0,0.0,0.0,0.0,0.0])
    ierr = psspy.scal_2(2,0,2,[2,3,1,1,0],[ _f,-change,_f,_f, _f,_f,_f])

Sir, here as far as i understand the issue you may use the following commands depending on the requirement

1) if you want report to send to standard psse gui you may use

psspy.report_output(1)

2) if you want it to directed to specific file in a drive you may change to

psspy.report_output(2,"file name with complete address",0)

i believe your problem may be solved with this

How can we add the GIS data of the buses from google earth kmz file to the sld of psse.? how can we integrate google earth to psse.?

please check weather you have added psspybin and psspy27 path in environment variables.

Sir, With the data of buses(nodes) and lines(edges) you can plot the network plot using networkx library of python.

example:

import networkx as net
buses = ["101","102","103","104","105"]
lines = [("101","102"),("102","103"), ("102","104"),("103","105") ]
G = net.Graph()
G.add_nodes_from(buses)
G.add_edges_from(lines)
net.draw(G,with_labels=True)

you will get the neat network plot without psse in python

the api code of abusint can be used to retrive all the bus numbers in a subsystem and the corresponding locations is assigned by experiance or trail and error mathod.

growbus api is used to draw the bus in sld of psse with x and y coordinates

you can minimize the trail and error by using python(machine language script)

for studying all the python command api's you can refer at the api document at PTI/PSSE34(OR ANY)/DOC

yes the x and y are the cartesian coordinate assuming 0,0 is at the center of the slider diagram

Sir, In the dynamic simulation you can actually calculate cct using python while loop along with python automate file. This while loop check can be done with reporting tool and critical fault limit.

Its acuracy is as good as with the python program alpha variable

1) you can learn psse basics from the youtube and udemy(online learning course). Those are the only the basic operations. you can do a lot more than those in the vedios or course.

No python is not necessary for the usage of PSSE you can compensate them with the batch commands or manual GUI operations. python only gives edge to the ease automation of the routine steps and increase speed of activity.

Change the pc time by 1 year and use it again

how and where can we find the dynamic simulation data, and how can we evaluate those systems
