Hi everyone,

Can I change the load with time in dynamic simulation? I’m run for psse32.

I want to set that load is followed time.

Example: To set every 1 microsecond, load will increased/ decreased 10 MW.

Thank you.

Advanced solution: By writing a user-written dynamic load model you can update the bus load at every time step. See Program Operation Guide, Chapter 21.9 for details.

Simple solution: If you don't need to change the load so frequently during the simulation you can run to t1, change the load with a load changing API, run to t2, change the load again, etc.

If you really wish to change the load every millisecond (I assume you meant millisecond and not microsecond!) you need the Advanced solution, :-)

The simple solution is good enough for us new learners. But there is no Program Operation Guide in the documentaries, the most similar part might be Program Operation Manual? And the is no Chapter 21.9 either.

Sorry for the typo, I meant look into "Model Writing" in Program Operation Manual (POM), Chapter 23.9 (ver 33)

Thank you! My edition is 32, so the menu is different from yours. The chapter title helps, I've got your idea.

You can find in chapter 20 (model writing) for details. There is an example about user-written exciter.
