Dear Vivek,

Interrupt able loads can be modeled by resistance or generally impedance with an embedded resistance and series controlled switch. The controlled switch is an element which makes the path to the load on or off according a control voltage applied to it. So, one can program the load interruptions.

Best wishes

Thanks a lot Prof. Abdelhalim for sharing your knowledge!!

In can add that the dynamic modeling could be carried out by z- transformations.    Best wishes,

in the simulator; you can add a random or a predefined interrupt; for example: for each t time you have an interrupt; t could be random or fixed

I hope it help.
