state feedback controller design(based on reduction model)

[Leona-kk]

Hi Dr. Cui and Jining,

Normally, we need model reduction and design a feedback controller for the larger system. Now, for Kundur system, I have reduced the model for 5252 matrix to 22 (for example) and designed an LQR for this reduction system. But here the problem is how I can add a reduction model controller to the original system in the Andes and do TDS.

I feel it needs some extra design efforts.

1. In your reduction model, determine the controller's input and output variables. For example, the controller might take the variable omega of SynGen as input and tm of SynGen as output.
2. Developing a controller model. The model will take omega as input (reference to self.omega = ExtState(...) for how to get the source variable), and add to pref (refer to self.tm = ExtAlgeb(...) for how to feedback it to the target variable).

Welcome further discussion if you can give more details of your desired controllers.

Hi jining,
Thank you so much for the suggestions. I will consider this way.
