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

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.

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.

Update: oemof user meeting – May 8th, 2018

The user meeting takes place on May 8th, 2018 from 10 am. You can find the agenda and further information here. Optionally we can have a dinner in the evening and take the morning of the next day to continue our work in the working groups. But if you can come for only one day that’s totally fine. We look forward to welcoming you in Magdeburg!
