hi @Hofsmo we can add this as a request but I think we aren't well positioned at the moment to make this a feature. If you have ideas, please paste them here or open a PR and we start exploring the use of PSID with stochastic inputs. |

Hi,
I have been working a bit with system identification in power system. In these studies it is important that the power system is excited by an external signal. I typically do this by modelling random load changes as a Wiener-process. Another important concept is that of process noise, which I sometimes model as filtered white noise added to for instance the rotational speed of a synchronous machine.
I found this simple tutorial showing how to add stochasticity to an ODEProblem https://matbesancon.xyz/post/2017-12-14-diffeq-julia/ . I was thinking if maybe it is possible to first create the problem using your package and then later add stochasticity by creating an SDEProblem as in the tutorial. I did several unsuccessful attempts of achieving this, so I was wondering if maybe there are better ways of doing this.
If you have any hints on how I can add stochastic inputs to simulations using your package, I would be very happy.
Cheers Sigurd
