open_plan stakeholder workshop (in German) — release of the first version of the open_plan tool

As part of the open_plan research project, we invite you to the third stakeholder workshop and look forward to presenting version 1.0 of the open_plan tool. If you are interested you can register here. The workshop will take place on 20.10.2021 from 10–13:00 online. Workshop language is German.

In the open_plan project we are going to develop a user interface to build an energy system with oemof. During the development process, we focused on user-friendliness, which is a key requirement of our partners. In this context, we also would like to get feedback from the oemof community on our results and release the tool for first use.

We would like to point out that the open_plan tool is still under development. Nevertheless, we would like to release the tool with its current development status for initial use so that we can incorporate your feedback into the further development of the tool at an early stage. With this approach, we ensure that the requirements of our partners for the open_plan tool are met in the best possible way.

We look forward to a constructive exchange!

DHNx (v0.0.1) – Gorgeous Grids

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.

oemof.thermal (v0.0.4) – Virtuous Validation

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.

oemof.thermal (v0.0.3) – Amazing Absorption

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.

oemof.thermal (v0.0.2) – Fancy Facades

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.

First release of oemof.thermal (v0.0.1)

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

Biggest community ever at the anniversary developer meeting

The oemof community gathered from 4th to 6th of December 2019 for the developer meeting in the Beuth-Halle at Beuth University of Applied Sciences. Besides the celebration of oemof’s 5th birthday we intensely worked together (among others) on the further development of oemof libraries, the facades structure of components, rolling horizon approaches, GitHub Workflows and the improvement of the website. We gathered first ideas for an oemof foundation and shared experiences with paid support. We also decided the unbundling of oemof and solph, so that the next major release will be a v0.4.0 solph release. Apart from the intense work we celebrated oemof’s 5th birthday with a nice birthday cake and a funny presentation of the history of oemof’s development.

Growing developer community at the 9th oemof developer meeting in Flensburg

Last week the 8th oemof developer meeting took place in Flensburg. More and more people use the oemof framework for their projects and are ready to participate in the developing process.

The developer meeting is always a good place to meet the people behind the scenes, introduce own problems on energy system modelling and gradually learn about the structures of the developing process.

Smiling developers in the nature – since its not their natural habitat this is a rare phenomenon

9th oemof developer meeting – 5-7 November in Flensburg

In the beginning of November the next oemof developer meeting takes place in Flensburg.

Our developer meetings take place every six months and aim at the further development of new features and functions within oemof. Moreover we will discuss the future community structure and the collaborative programming process.

Anyone who is interested is cordially invited to participate. Please find detailled information and the topics we collected up to now here: https://github.com/oemof/organisation/wiki/Meeting-November-2018

If you want to be part of it or have topics to add, please contact us via oemof2018@rl-institut.de or https://github.com/oemof/organisation/issues/31

Modelling cooling concepts for Oman with oemof

From 2nd to 6th September 2018, the Beuth Hochschule für Technik Berlin supported a training course on sustainable energy concepts at the Sultan Qaboos University (SQU) in Muscat, Oman. The course, jointly led by experts from the German Research Centre for Geosciences (GFZ), the Research Council of Oman (TRC) and the Centre for Community Service & Continuing Education at SQU, applied oemof to model cooling concepts in Oman.
