Issues in "Small Example"

[Fernando3161]

Greetings!
I am trying to get to know the tool. I am starting with the small example.
Following happened when using the current repository as source for energiapy:

I found issues while building the processes. I think that prod_max was replaced with cap_max. However this change was not documented

LiI = Process(name='LiI', storage=Power, capex=1302182, fopex=41432, vopex=2000, cap_max = 100, #prod_max=100, cap_min=10, store_max=100, label='Lithium-ion battery', basis='MW')

After that, the problem cannot be formulated. After some testing, there are some issues when trying to apply
Constraints.RESOURCE_BALANCE
and/or
Constraints.PRODUCTION

in the problem formulation. When I comment this constraing, the problem can be formulated, however the results are meaningles.

Any idea how to solve this?

When using the pip package version, following must be commented:

LiI = Process(name='LiI', storage=Power, capex=1302182, fopex=41432, vopex=2000, # cap_max = 100, prod_max=100, # cap_min=10, store_max=100, label='Lithium-ion battery', basis='MW')

so the code can work

Hey,

Thank you so much for bringing this to my attention, and sorry for the late response.

You are right. I changed prod_max/prod_min to cap_max/cap_min. This change will however only be reflected in the next pip package version of energiapy.

I am not proud of the change but think 'prod' was a misnomer as the actual parameter sets the maximum network capacity of the process. I am also adding a prod_max but this will capacitate the maximum/minimum production in the scheduling scale if some one wants to work on fixed design problems.

The git version takes cap_max. I thought I should make this change sooner than later even though current users will have to make changes to their existing code, regrettably.

Thank you for using energiapy! Please feel free to reach out to me on cacodcar@tamu.edu if you have any specific questions. Would be interesting for me to see what users actually want in the package in terms of functionality, constraints, etc. Note that there are more examples in the mat-wexp branch under the folder examples. I havent put them in the documentation yet as I still need to clean them up a bit.

Thanks and kind regards,

Rahul

I have made the change in the docs. The example should work for the pip package version
