In the @jconto profile, there is a google drive link that includes most of the IEEE cases data. I have used that data for IEEE39. Here is the link: https://drive.google.com/drive/folder...

The general way is the way which @perolofl said, you can also record the changes in the .dyr and all the changes in your simulation. In especial case: for example, if you want to change the active and reactive power of the generator at bus 10 to 30 and 50, you can use the following code

psspy.machine_chng_2(10,r"""1""",[_i,_i,_i,_i,_i,_i],[_f, 50.0,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f]) #change the Q to 50 psspy.machine_chng_2(10,r"""1""",[_i,_i,_i,_i,_i,_i],[ 30.0,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f,_f]) #change the P to 30 Based on the above codes, each of the _i, and -f are as follows:

Bus Number, Bus Name, Id, Term Node Num , Term Node Name, Area Num , Area Name, Zone Num ,Zone Name, Code VSched (up), Remote Bus Number, In Service PGen (MW), PMax (MW), PMin (MW), QGen (Mvar), QMax (Mvar), QMin (Mvar), Mbase (MVA), R Source (up), X Source (up), RTran (pu)

I wanted to put the code here, but it seems that the length exceeds the maximum length.

Thank you @jconto. That problem was solved, but now I have "python load failed with error code 126" error for running the psse from python.

I have used the following code to import psspy(my psse is PSSE 35), however I have got the following error:

import os, sys
sys_path_PSSE = r'C:\Program Files\PTI\PSSE35\35.2\PSSPY27'  # or where else you find the psspy.pyc
sys.path.append(sys_path_PSSE)
os_path_PSSE = r'C:\Program Files\PTI\PSSE35\35.2\PSSBIN'  # or where else you find the psse.exe
os.environ['PATH'] = ';' + os_path_PSSE

The error:

import psspy
File ".\psspy.py", line 56, in <module>
ImportError: DLL load failed: %1 is not a valid Win32 application.

could you help me with that? Thanks

I have the same error with my psse.

I am looking for the parameters of a composite load such as "CMLDBLDGU2" in PSS/E. Can anybody help me how to find that? thank you.

Hello everyone,

I want to implement a Kalman filter for a system that implements in PSSE. I need the state space and state transition matrices. Could anyone help me how to find the state transition of the models in PSSE? Thank you so much

@jconto Thank you so much. You are always helpful.

I want to apply a fault at a specific time in the network. But I don't know how to set the time. I have used the following command. Could you please help me, for example, I want to trip a line between bus 1 and 2 at time 10 seconds and the fault clean at time 15 sec.

I have tried to put the following in the code style, but I could not:(

psspy.dist_branch_fault(2, 3, r"""1""", 1, 13.8, [0.0, -10]) #\\ psspy.dist_branch_fault(4, 5, r"""1""", 1, 100.0, [0.0, -10])\\ psspy.dist_bus_fault(6, 1, 230.0, [0.0, -1000]) #fault at a bus

Hello, I want to apply a fault on a line in a simple network, but the option for choosing the disturbances is inactive. Could you help me to solve that? Thanks

I want to run the model in this google drive "Unfortunately I could not put the link" the "BESSJconto", I already put the file in one folder, at first I have loaded the PSSE. When I have run the "SMIBBESS.py" I have got this error :

Could someone help me how to solve this error? And If we want to get the output channel in the "SMIBBESS.py" file, it needs only to add the "channelsBESS_RE" to the main file? Thank you so much

I am new to psse and modeling, I want to do some modeling and model verification for inverter-based resources. I don't know how to start and how to develop the model. Does anybody have any file, video, or good reference to learn the modeling the reecc or reeca in PSSE? Thank you so much
