We have noticed that the new release of pyomo has greatly increased the calculation time within solph.
A hotfix to this requires manual downgrading to 5.7.2 of pyomo.

A new major version of TESPy has been published. The releases Gibb’s Gallery and User’s Universe feature major improvements in the software.
A new major version of TESPy has been published. The releases Gibb’s Gallery and User’s Universe feature major improvements in the software, amongst others:
On top of that, the core of the TESPy components has been reworked to lower the access barriers for new developers.
The new version also comes with an new API, therefore minor changes in your model will be necessary. Read about all changes necessary in the release notes of Gibb’s Gallery and the release notes of User’s Universe. You will find all new features available in those notes, too.
We just published the first release of DHNx!
With DHNx, we introduce a package for district heating network optimization and simulation models.
The aim of DHNx is to develop a library for the planning and modelling of district heating network systems. The package has two main features: the optimization (routing and sizing) of district heating network systems, and the hydraulic and thermal simulation of a district heating network with given pipe diameters.
Examples can be found here here.
We have just published the fourth release of the oemof.thermal repository.
With the fourth release of oemof-thermal we have validated the compression heat pump, the compression chiller and the stratified thermal storage using data provided by the Universidad Politécnica de Madrid and the energy supplier Naturstrom AG. The results are provided in the documentation.

We just published the third release of the oemof.thermal repository.
It’s time to proudly introduce a new component – the absorption chiller. Within the module we provide functions to calculate, among others, the characteristic equation, the coefficient of performance and the cooling capacity. See the documentation for more information.
All modules have been updated to oemof.solph v0.4
See the What’s new section for further details about the third release.
After oemof v0.3.2, we decided to make oemof’s structure more clear: Both, the framework (including e.g. TESPy) and the Package for energy system optimisation (using solph) were called the same – oemof. With the release of v0.4.0, there are now split packages for oemof.solph, oemof.network, and oemof.tools.
The third major version of TESPy – Mayer’s Merit – has been released together with a paper in the Journal of Open Source Software, available at the Open Journals website. The new version carries many new features, improved calculation stability for fluid mixtures and back end changes. Continue reading “TESPy v0.3.0 – Mayer’s Merit”
We just published the second release of the oemof.thermal repository.
A brand-new feature are the facade classes that simplify instantiating the components. Facades for these three components are now ready to be used: SolarThermalCollector, ParabolicTroughCollector and StratifiedThermalStorage.
The documentation has been revised and extended. The repository now has function tests, and the facades are tested with constraints test.
See the What’s new section for further details of the second release.
There will be a tutorial about the oemof.thermal repository at the upcoming virtual oemof developer and user meeting.
The second major version (Clausius’ Circus) of TESPy has been released in January 2020 and version 0.2.1 – Fourier’s Fable just three weeks after. The release contains many back end improvements to facilitate future development as well as some new features. Continue reading “TESPy v0.2.x – Clausius’ Circus and Fourier’s Fable”
We are happy to announce the first release of the oemof.thermal package (v0.0.1) to model thermal energy systems: https://github.com/oemof/oemof-thermal
The package includes the following four components: stratified thermal storage, compression heat pumps and chillers, solar thermal collectors and concentrating solar power.
Please find the documentation of the components and examples here: https://oemof-thermal.readthedocs.io/en/stable/
If you find bugs or have suggestions for improvement we would be happy if you write an issue here: https://github.com/oemof/oemof-thermal/issues
