Thermal Module Empty Collection Reduction

[AlannLiu]

Hello. When I try to run GenX, the code stops at the thermal module.

This is my error message:
ERROR: LoadError: MethodError: reducing over an empty collection is not allowed; consider supplying init to the reducer

Hi Alann,

This issue was fixed in GenX v0.3.6, and is due to changes made in JuMP v1.13; I believe we had previously been using v1.11. We'd recommend that you update to v0.3.6.

If for some reason you cannot update GenX, but you can modify your installation, make the changes as seen in the commit here: 7c85cc7

I believe this issue is caused when some thermal generators have Up_Time or Down_Time of 0.

[rebeccamccabe]

We were able to fix this issue with your recommendation. Thank you.

Glad to hear it.
