Thank you for your response! I meant as an example, during a contingency configuration, a feeder may be taking more MW/MVAR load, in which situation, more MVAR would be drawn from this feeder, so I want the capacitor bank to go online and inject VARS into the system.

Hi,

Wondering if a capacitor bank can be set to VAR control/voltage override in PSSE? I'm trying to get the cap bank to turn on/off based on the reactive power into the bus where the bank is connected and also force a voltage override when the voltage is soft. If this is doable, please let me know how it can be done. I' have access to PSSE 33 and 34 versions.

Thanks in advance for your help!

This worked. Thanks a lot for your help.

Thanks for your response! It does record also the pre-assigned generation and show that in the code. Ultimately, I'm trying to run a for loop to change all MW loads one-by-one without editing generation.

Hi, I'm experimenting with interfacing Excel and PSSE V33, I'm trying to change only MW load of a specific region without changing the pre-assigned generation. I've tried different combinations for psspy.scal2 arguments but still not being able to change MW loads only. Is there a way to read off an excel sheet and assign that value as a new total of Load-MW? The excel import piece is working fine, just need the proper arguments for psspy.scal2 and PSSE documentation dos not provide any examples. Below is my code, please help:

______Importing Load Data________

import excelpy xlsfile = r"C:\Users\mhandy\OneDrive - Eversource Energy\Desktop\Loads.xlsx" testxls = excelpy.workbook(xlsfile,"test",mode='r') row=1 col=1 region1 = testxls.get_cell((row,col));

______Allocating Load - PSSE Recording________

psspy.bsys(0,0,[0.0, 765.],0,[],0,[],0,[],1,[101]) psspy.scal2(0,0,1,[0,0,0,0,0],[0.0,0.0,0.0,0.0,0.0,0.0,0.0]) psspy.scal2(0,1,2,[0,1,0,1,0],[region1,0,0,0,0,0,0]) # I want to use the preassigned generation without modifying it.

psspy.fdns([0,0,0,1,1,0,99,0])

testxls.close()
