Are there any methods to improve the speed of batch dynamic simulations?

Hi, everyone!

I wrote codes in python to looply call PSS/E dynamic simulations. But the speed is not very fast. It took me about 9 hours to obtain 100 samples. When I tried to increase the simulation step, it can not obtain correct results. So the maximum of simulation step can only be 0.01s. Therefore, i want to ask if there are any methods to speed it up.

Thank you for your help! I would appreciate it very much!

Search for "parallel" in this forum.

0.01s seems long. We run 1/4 cycle time steps.

You can improve speed by utilizing parallel processing which will use multiple cores of your machine. Just to get a sense of speed improvement, you can initially split your job into multiple small batches(e.g. 4 batches of 25 simulations each) and trigger all of them at once. If this helps, you can then create python scripts to automatically do this for you.
