Re: [TRNSYS-users] optimazation with TrnOpt/GenOpt

Hello Johannes,

I do not fully understand your goal: Do you want to receive 8760 optimized control variables?
This will not work. If you want to optimize your shading control, you should play with the value that "triggers" your shading system (like total irradiation on a surface). Maybe you can use monthly values. Then you have 12 variables to optimize, which is a managable goal with GenOpt. And also could be adapted in a real system...

But you have to define your cost function very carefully, especially when you want to optimize two (to some extent) opposed values like room temperature & irradiation.

Best regards,
Jochen

Dear trnsys users,

 

I`m currently trying to optimize some control signals in my trnsys
model.

Is there any possibility to optimize the control signals for every
single hour

of the year? For example I would like to get a certain hourly signal for
the shading

control (0, 0.1, 0.2,…, 1). 

The error function is the indoor temperature/ irradiation.

Is that possible with TrnOpt?

 

Thanks a lot.

 

Best,

Johannes

Dear Joke,

for giving more detailed help we need to have a look at your IDF.

Best regards,
