How to change induction machine power consumption during dynamic simulations?

edit

Hello all,

I have a IEEE 39 bus case with some induction machine loads (CIM5BL). In the raw file, they are modeled as constant power loads, with corresponding entries in the dyr file.

I am trying to change the power consumption of these induction machine loads during dynamic simulations. Previously, when i intended to do this, i just stopped the simulations, used the following command: ierr = psspy.loadchng5()

And then continued the simulation.

But this does not seem to work for these induction loads. Do i have to do this using the CIM5BL vars instead?

Thanks in advance!
