Hyperlinked release notes can be found here: file:///home/tom/fias/lib/pypsa/doc/_build/html/release_notes.html#pypsa-0-15-0-8th-november-2019 This release contains new improvements and bug fixes. * The unit commitment (UC) has been revamped to take account of constraints at the beginning and end of the simulated snapshots better. This is particularly u seful for rolling horizon UC. UC now accounts for up-time and down-time in the periods before the snapshots. The generator attribute initial_status has been replaced with two attributes up_time_before and down_time_before to give information about the status before network.snapshots. At the end of the simulated snapshots, minimum up-times and down-times are also enforced. Ramping constraints also look before the simulation at previous results, if there are any. See the unit commitment documentation for full details. The UC example has been updated with a rolling horizon example at the end. * Documentation is now available on readthedocs, with information about functions pulled from the docstrings. * The dependency on cartopy is now an optional extra. * PyPSA now works with pandas 0.25 and above, and networkx above 2.3. * A bug was fixed that broke the Security-Constrained Linear Optimal Power Flow (SCLOPF) constraints with extendable lines. * Network plotting can now plot arrows to indicate the direction of flow. * The objective sense (minimize or maximize) can now be set (default remains minimize). * The network.snapshot_weightings is now carried over when the network is clustered. * Various other minor fixes. We thank colleagues at TERI for assisting with testing the new unit commitment code, Clara Büttner for finding the SCLOPF bug, and all others who contributed issues and pull requests.
