how to model a varying load in Simulink using specialized power system library in single phase

Hello, I'm modelling a Full-Active Hybrid Energy Storage System in Simulink using specialized power system library, For getting proper results, i need a varying load. The varying load prsent in this library is in 3-phase.. I need a single phase varying load. Can anyone help?

Hi Irfan,

One way of doing this is by creating your own Single-phase varying load. To do this you can use the "Variable Resistor" , "Variable Capacitor" and "Variable inductor" and rearrange them to connect them in parallel or series. You use signal blocks from Simulink > Sources to control the impedence values.

You can refer this following example where a "Variable inductor" is used.

If you need to use a "Single Phase Dynamic Load" you can refer to the following example and reuse the custom built block in your model.

Hope this answers your query.

Thank you, i used the single phase dynamic block and it worked perfectly.
