24-hour simulation, micro-grid

I have built a SIMULINK model of a hydro generator (SIMULINK synchronous machine blocks), Battery system (modelled as negative power - three-phase dynamic load), PV (modelled as negative power - three-phase dynamic load) with a variable load (three-phase dynamic load) and base load (three-phase parallel RLC load) running in phasor solver simulation. My model is fine giving expected results but running for 500 seconds. Wish to have the simulation time of 86,400seconds(24 hours) so as to exactly correlate daily PV irradiance with power output but my model is too slow to allow that. It will probably need one week to simulate 86,400 seconds. I have seen simulations with similar components like the Simulink example model “power_V2G” with similar blocks of a diesel generator, PV and battery system equivalents and are able to simulate 86,400 seconds in a very short time, approximately 5 seconds.

I am hoping that someone can give me some insight into what I need to consider to run models over a 24-hour periods.

have it actually run in 5 seconds? for me it is taking minutes even to complete one second simulation period.

Also, according to the second answer of this post. Simulink uses ETM simulations and not RMS, can someone deny or confirm this?

Hi Ronald,

You can refer to the Speed Up Simulation page.
