Can the powergui Load Flow tool initialize a user built model in Simulink?

Hello all,
I am using the load flow tool in Simulink to initialize the Synchronous Generators I have in my models. And this works good. However, I am also including a wind farm in the power system. The wind farm is a model built by me. I have seen that the load flow does not affect the wind farm initialization, nor does it take the wind farm into account when calculating the quantities for the rest of the power system. Therefore, the system does not start in steady-state.
Does anyone know if the load flow tool works only with the simulink library models? Or can it be used to calculate and initialize a user built model as well? If it can, do you know any examples that I could use for inspiration?
Thank you all. Radu

Hello Radu,
If you execute the following command from the MATLAB Command Window do you see Synchronous Generators in the Wind Farm model show up?
>> power_loadflow('-v2', sys)
Where "sys" is your model name as a string.
Additionally, how do you include your wind farm in the power system? Is it a model reference or a masked subsystem?

Hello Radu,
yes, it is possible, but they need to be set up correctly. Please respond to Jordan's questions if you want to track down an answer.
