This is proposed without further explanations.
This issue is about underlining the fact that this restrictions (**imports.minimize_production**) isn't sufficient to really achieve an optimization of self-consumption with respect to the grid. Although this is going to give a great approximation of self-consomption/self-production ratio on the period, this method doesn't give restrictions on the exports behavior. Therefore, this method lead to an anormal use of exports and is not modelling a correct storage when looking at the step to step behavior.
Optimizing the self-consumption should be constructed by two restrictions : one on the imports ( **imports.minimize_production** ) and one on the exports ( **exports.minimize_consumption** ).
To illustrate this difference, here is two cases of a self-consumption optimization for a building with a load, a production and a battery. The first case doesn't include the exports restriction, while the next one includes both restrictions.

In green, it is the battery behavior (positive value is charging, negative value is discharging. It is possible to notice that without the restrictions on the exports, the battery is charging and exporting (which is not the optimal behavior) rather than storing the energy to use it when the production is low (which is optimizing the self-consumption).https://gricad-gitlab.univ-grenoble-alpes.fr/omegalpes/omegalpes/-/issues/70Organization of the Git - Split between tutorial notebooks, unfunctionnal not...2021-11-18T11:14:31+01:00Pierre-Thomas Demarspierre-thomas.demars@grenoble-inp.orgOrganization of the Git - Split between tutorial notebooks, unfunctionnal notebooks and article notebooksFinding the tutorial notebooks could be improve byt dedicating a clear file, which would make them apart from the article notebooks and the other notebooksFinding the tutorial notebooks could be improve byt dedicating a clear file, which would make them apart from the article notebooks and the other notebookshttps://gricad-gitlab.univ-grenoble-alpes.fr/omegalpes/omegalpes/-/issues/64Color code for OMEGAlpes graphic representation2020-12-10T18:41:23+01:00Sacha HodencqColor code for OMEGAlpes graphic representationBefore updating OMEGalpes documentation regarding its graphic documentation with its current version (commit 61c9d79c97450c3929ecbfd2a7776f4c4ac0f491) , some questions and thoughts:

- What color for:
- Gas : green that is more common for gas instead of the current yellow
- Electriity : blue that is also more standard, but currently for cold
- conversion_unit : black empty rectangle rather than green full one.
- Differentiating hot and cold or keeping thermal energy type. Question of the thermal dissipation units where hot and cold would not be able to mix.Sacha HodencqSacha Hodencq
