| 43029d5 | Tom Brown | 10 January 2020, 15:46:59 UTC | PyPSA Version 0.16.1 Hyperlinked release notes can be found here: https://pypsa.readthedocs.io/en/latest/release_notes.html#pypsa-0-16-1-10th-january-2020 This release contains a few minor bux fixes from the introduction of nomopyomo in the previous release, as well as a few minor features. * When using the nomopyomo formulation of the LOPF with network.lopf(pyomo=False), PyPSA was not correcting the bus marginal prices by dividing by the network.snapshot_weightings, as is done in the pyomo formulation. This correction is now applied in the nomopyomo formulation to be consistent with the pyomo formulation. (The reason this correction is applied is so that the prices have a clear currency/MWh definition regardless of the snapshot weighting. It also makes them stay roughly the same when snapshots are aggregated: e.g. if hourly simulations are sampled every n-hours, and the snapshot weighting is n.) * The status, termination_condition that the network.lopf returns is now consistent between the nomopyomo and pyomo formulations. The possible return values are documented in the LOPF docstring, see also the documentation. Furthermore in the nomopyomo formulation, the solution is still returned when gurobi finds a suboptimal solution, since this solution is usually close to optimal. In this case the LOPF returns a status of warning and a termination_condition of suboptimal. * For plotting with network.plot() you can override the bus coordinates by passing it a layouter function from networkx. See the docstring for more information. This is particularly useful for networks with no defined coordinates. * For plotting with network.iplot() a background from mapbox can now be integrated. Please note that we are still aware of one implementation difference between nomopyomo and pyomo, namely that nomopyomo doesn’t read out shadow prices for non-extendable branches, see the github issue. | 10 January 2020, 15:46:59 UTC |

| dbdea2a | Tom Brown | 02 January 2020, 18:34:25 UTC | linopf: Correct marginal prices by snapshot weightings This is then consistent with the marginal prices in the Pyomo LOPF. It also means the prices have a clear EUR/MWh definition, and makes them stay roughly the same when snapshots are aggregated. | 02 January 2020, 18:34:25 UTC |

Status, termination_condition is either: ok, optimal or: warning, infeasible For gurobi there are two additional options: If gurobi is using the barrier method and has a sub-optimal solution, nomopyomo will still read the solution and return: warning, suboptimal If gurobi is using the barrier method, sometimes it cannot distinguish between an infeasible and an unbounded problem, so returns: warning, infeasible or unbounded | 31 December 2019, 12:09:19 UTC |

| 0e4fb5f | Tom Brown | 20 December 2019, 13:29:42 UTC | PyPSA Version 0.16.0 Hyperlinked release notes can be found here: https://pypsa.readthedocs.io/en/latest/release_notes.html#pypsa-0-16-0-20th-december-2019 This release contains major new features. It is also the first release to drop support for Python 2.7. Only Python 3.6 and 3.7 are supported going forward. Python 3.8 will be supported as soon as the gurobipy package in conda is updated. * A new version of the linear optimal power flow (LOPF) has been introduced that uses a custom optimization framework rather than Pyomo. The new framework, based on nomoypomo, uses barely any memory and is much faster than Pyomo. As a result the total memory usage of PyPSA processing and gurobi is less than a third what it is with Pyomo for large problems with millions of variables that take several gigabytes of memory (see this graphical comparison for a large network optimization). The new framework is not enabled by default. To enable it, use network.lopf(pyomo=False). Almost all features of the regular network.lopf are implemented with the exception of minimum down/up time and start up/shut down costs for unit commitment. If you use the extra_functionality argument for network.lopf you will need to update your code for the new syntax. There is documentation for the new syntax as well as a Jupyter notebook of examples. * Distributed active power slack is now implemented for the full non-linear power flow. If you pass network.pf() the argument distribute_slack=True, it will distribute the slack power across generators proportional to generator dispatch by default, or according to the distribution scheme provided in the argument slack_weights. If distribute_slack=False only the slack generator takes up the slack. There is further documentation. * Unit testing is now performed on all of GNU/Linux, Windows and MacOS. * NB: You may need to update your version of the package six. Special thanks for this release to Fabian Hofmann for implementing the nomopyomo framework in PyPSA and Fabian Neumann for providing the customizable distributed slack. | 20 December 2019, 13:29:42 UTC |
