Single Phase Time-Varying Load

Hello,

I have modelled household and electric vehicle load data, which now needs to be implemented into Simulink. This is a time-varying load (every minute). I am unsure of how to model this in Simulink. Any help would be greatly appreciated! Thanks!

How did you model the household please?

You can use the 'Three phase dynamic load' to handle the time varying load data. The following example can be a good starting point:

Also, this MATLAB Answers post talks more about this. Have a look at the following link:

Thanks for the reply! I don't understand how you can input external data into it when there's no specific frequency. Not to mention the load isn't a waveform, but stochastic. Furthermore, my load changes at specific time steps, not continuously like a dynamic load. Am I missing something that allows me to still utilize this block for a single phase system?

I have already looked through that answer, as well as every other I could find with not too much help.
