Robustness MILP optimisations lead with OMEGAlpes are developed to be robust and reproducible. If any issue is met with these tools, please indicate them in the Issues section of its gitlab.
Comparability / Validation The aim is not to provide concrete results but to present comprehensive OMEGAlpes capabilities. Energy and exergy models are close to widespread research work (see Fito et al. – DOI: doi: 10.1016/j.seta.2020.100894) Actor package has been developed referring to social research work (see Morriet et al. – DOI: 10.26868/25222708.2019.210472) An article and a corresponding notebook are available in order to get a detailed description of the energy models and equations.
Conclusions One should not deduce any conclusion considering the waste heat recovery from the provided results. Here, the focus is made on a description of the implemented energy models, the creation of a corresponding optimisation model in addition to exergy and social considerations.

If you find bugs or if you have ideas to improve the Open Energy Platform, you are welcome to add your comments to the existing issues on GitHub.
You can also fork the project and get involved.

Please note that the platform is still under construction and therefore the design of this page is still highly volatile!
