How to Make the Reference Value of REGFM_A1 Follow a Custom Setpoint?

Hi everyone, I'm currently testing the REGFM_A1 model. I would like to control the reference values of active power, reactive power, and voltage so that they follow my own predefined setpoint curves. How can I achieve this?

You need to use a plant controller model.

I don't have the block diagrams in front of me but typically, the reference values can be changed at the VAR parameters of the model. For example, look for the VAR location where the reference voltage is stored and change it during dynamic simulation.

I’m using the REGFM_A1 and REPCA_A1 models in my dynamic simulation. I attempted to change the value of VAR(L+3) in the REPCA_A1 model during the simulation, which corresponds to the active power reference (plant_ref). However, I observed that the change had no effect on the simulation results.

Below is the code I used — could you please help me check whether there might be any mistake or misunderstanding in how I’m applying it? psspy.strt(0, output_file) psspy.run(0, 5.0, 0, 0, 0) psspy.change_var(4, 0.5) psspy.run(0, 25.0, 0, 0, 0)

Use psspy.change_wnmod_var(ibus, id, name, j, rdata) to change the VAR.

As mentioned by perolofl, use psspy.change_wnmod_var API to change the VAR that points to whatever reference parameter you want to be changed.
