Refine and extend data models for capturing uncertainty statistics #60

Closed jonssonchristian closed 4 months ago

jonssonchristian commented 4 months ago

This PR mainly addresses #53. It introduces the option to define a time frame and return period for statistics (e.g. the P90 value corresponding to the first 10 years with a return period of one year). The descriptions and requirements for gross and net energy assessment results datasets are refine. It also includes a few minor unrelated refinements.

I pushed some updates to this PR based on the outcomes of the EYA DEF group meeting on 2024-07-16.

Most notably, I removed the specification of the start and end of the time frame under statistic definitions. Upon further consideration, I believe that information should be captured under the binning dimensions rather than under the definition of the statistic. It is confusing if it could potentially be defined in two places.

The inter-annual variability now has a fixed return period of 1 year, to remove the possibility of inconsistencies.

I also added some more clarification around which results are required and optional in the energy assessment data models.

Hi @AlinaBurmesterRWE, many thanks for the review and feedback. I have corrected the typo you spotted and extended the titles to be more descriptive (for both gross and net energy results).
