v0.5.0: Rigorous refactoring

v0.5.0 (February 3rd, 2023)

API changes

• Parts of the energy system graph are now clearly structured into buses, components, and flows.
• Public and private API are be more distinguished now. ('_' signifies private, public API is defined in init files.)
• Experimental code is now sitting in submodules called experimental (replaces "custom").
• The flow arguments summed_minand summed_max now have the more descriptive names full_load_time_min and full_load_time_max.
• Keyword arguments are now explicit. Among other things, this will catch typos. Custom attributes can be added using the argument custom_attributes. Those will be passed down the class hierachy and can (possibly) be handled in parent classes.

New features

• Add inactivity_costs as an option for Flows. Inactivity costs is a cost for times where a Flow is not operated.
• It is now possible to optimise the size of Flows that have a status variable. Internally, this is done by the InvestNonConvexFlowBlock which provides the possibility to perform capacity optimization of assets considering their min/max loads, as well as their operation status.

Documentation

• Examples are added to the documentation.

Testing

• Discontinued usage of Nose, as it is deprecated in Pytest <https://docs.pytest.org/en/stable/deprecations.html#support-for-tests-written-for-nose>.

Known issues

• The format of the examples could be improved.

Note

• Tags v0.5.0, v0.5.0a, and v0.5.0b have identical source code.
• The tag has been adjusted to have a working DOI for this code.
