Hi,

My model includes 387 power plants that for Hydro power plants it has 2 categories; pump hydro storage(it has two type small power plants and big power plants) and reservoirs hydro station. My problem is that when I add new small pump storage to it, I encounter attached error, however I have made all needed changes to its respective subscripts. There is one subscript for pump hydro storage and they have two subrenge including small and big group. Can you help me how can I solve this problem?

Best Regards

Can you upload the model?

Unfortunatley, i am not allowed to upload it. When I added new region(country) to my model I did not get any error like this( of course because there is no subrenge for regions) but when I add new powerplant which is Pump hydro type that has such these subrenges I get this error. I have attached subscript of my small group of pump hydro here. Do you have any suggestion to fix it?

I'd need to see the model to figure out why you are getting errors. Screenshots are not really helpful.

Hi

Did you try doing the modifications directly on the text model?

I have experienced some problems using the equation editor for the subscripts and working directly on the text équations is OK.

Regards.

I think the problem is exactly what the error message reports - you have different subscripts on the right and left side of the equation. "ps hydrostation small" vs. "ps hydrostation small group." That only works if you have one mapped to the other.

Yes, your are right. I fixed it.
Thanks for your consideration
