2024 user meeting in Nordhausen: Thanks for joining!

The last user meeting was the biggest we ever had. We had very productive and inspiring discussions about using oemof (especially solph). Because of the size we gathered opinions in subgroups instead of making decisions about future developments in the plenary. Another reason for this also led to some other changes: Typically, we start with user presentations showing use-cases as well as open questions. This, however was scheduled as a point of the agenda of the parallel RET.Con. So, instead of gradually going to the core, we started with developer topics.

oemof user meeting 2024.02

From 7th to 9th of Februar 2024, we will have our annual user meeting, this time held in Nordhausen. It is set in the framework of the to the  7th Regenerative Energy Technology Conference (RET.Con) and the 20th anniversary celebrations of the course renewable energy technology (“Regenerative Energietechnik”) at the Nordhausen University of Applied Sciences.

With the program of the RET.Con being released, we now also created a (tentative) agenda for the oemof meeting 2024.02. In contrast to previous years, we will have the topics targeting more experienced users (like planning the development roadmap) at the first day. This allows to have topics also targeting beginners (e.g. the user presentations) open for visitors to the RET.Con.

If you plan to come, please register writing an email to usermeeting@oemof.org, telling your name and (if applicable) your institution. We still have open slot for user presentations and tutorials. So if you want to present what you are doing using oemof or even share some hands-on experience, we will try to fit your contribution in. Note that it is okay to give a presentation in German. If possible, we prefer to have at least slides or spoken word in English. In the past, user presentations were also used for problem statements to find help on a particular topic and to have “reversed tutorials” asking for guidance. Both are options also for this user meeting.

As always, there are no fees for the oemof user meeting. You have to organise the trip (travel and accommodation) by yourself, meals are self-paid (and optional, you are free to organise something separate). So, don’t be confused by the RET.Con conference fee, this one does not apply for us.

2023-11 dev days: Retrospective

oemof developers discussing possible implementations

In the last days, we intensively discussed the next steps in the development of oemof. It was very intense and exciting to see other enthusiastic developers in person, drafting solutions at the white board and reviewing code in the presence of the persons who wrote it. We discussed long-term plans but also very particular problems, e.g. how to rewrite up-times in solph so that they are meaningful in models with time-steps of varying length. The most noticeable topics were mostly considering solph:

oemof user meeting meets RET.Con

For next year’s user meeting, we take a special opportunity: It will be held from 7th to 9th of Februar 2024, partly in parallel to the  7th Regenerative Energy Technology Conference (RET.Con) in Nordhausen. The oemof user meeting will be in its established style, but we want to make it possible for attendees to the conference (which is held mostly in German) to visit presentations and tutorials given at the user meeting. Additionally, it is possible to add an entry for the proceedings of the conference.

This is also why we are announcing the user meeting already before the dev days have taken place: For the RET.Con, there is a deadline for abstract submission at the 30th of September 2023. Note that papers should be in German but presentations may also be in English. If you do not want to publish a paper, you can hand in a headline and a very brief summary for a talk until the 15th of November, so that an announcement can be made at the RET.Con. At last, of course you can ignore this early deadline and present something at the user meeting without having it announced at the conference.

If you want to want to submit something for the RET.Con via the oemof user meeting, please send an email to usermeeting@oemof.org. All emails to this address will also be forwarded to the organisers in Nordhausen.

oemof dev days – November 2023

We opened registration for the omof developer meeting 2023. (As suggested by the local organisers, Fraunhofer UMSICHT, they are now “dev days”.) The meeting will take place in the Osterfelder Straße 3 in Oberhausen from the 22nd to the 24th of November 2023. At the moment, the agenda is still blank and leaves plenty room for ideas. It will be continuously developed at https://github.com/oemof/oemof/wiki/Meeting-2023.11 – depending on suggestions from registrees.

We always try to keep the entry barrier as low as possible. The meeting is targeted to everybody who wants to contribute to oemof. Of course this includes the further development of the packages, but in the past there have been also non programming-related sessions, e.g. about the content of this website. We have no conference fee, you only have to organise and pay for travel, accommodation, and food. To register, please send an email to meetings@oemof.org or post a comment at https://github.com/oemof/oemof/issues/112.

oemof spring meeting 2023

we are pleased to announce the upcoming oemof user meeting, May 24th to 26th 2023 in Stuttgart. The meeting is open to all who use or develop the software, as well as interested new users. Thanks to the DLR site in Stuttgart for hosting us.

Being a community project, the meetings traditionally include the possibility to ask questions to fellow users and open discussion. We are happy to exchange ideas with developers and users rather than just promoting results. So let’s get together, share knowledge and inspire each other. Learn more about planned developments, find people to collaborate with on your projects and get your questions answered. We continuously gather information in the Meeting-2023.05 Wiki page (GitHub). Note that meals are self-paid as there is no conference fee.

To register, just write an email to meetings@oemof.org. Please tell your name, (if applicable) your institution, your GitHub user name, and if you want to present something. Unfortunately, we also need to know your nationality, so that you are allowed to enter the DLR campus.

What to expect?

oemof developer meeting November 2022

We finally opened registration for the omof developer meeting 2022. As suggested last year’s dev meeting, it will take place at Magdeburg University from the 09th to the 11th of November. One focus will definitely be on the next release of solph, but the agenda is kept flexible to meet the demands of the participants and will continuously developed at https://github.com/oemof/oemof/wiki/Meeting-2022.11.

Developer meetings are no closed shop but a great opportunity for a first contact for those who are considering to collaborate. In fact, it’s rather common that people join a developer before actively contributing. With this regard, the upcoming meeting is a particular good opportunity as there are a couple of freshly developed features also new to long-term developers.

To register, please send an email to meetings@oemof.org or post a comment at https://github.com/oemof/oemof/issues/100.

Thank you for joining the oemof spring meeting 2022

We want to thank all participants of this year’s oemof spring meeting. It’s always a joy to have a few days reserved for concentrated discussions around the things you create and investigate using oemof. Some of you already provided their slides, these are now available in the collection of oemof publications.

Presentation held at the first afternoon of the meeting which took place in the meeting hall of the meeting hall of the Danish minority living in Flensburg.

This year’s spring meeting wasn’t only the biggest in-person meeting but also probably the most international one. It was located almost in sight of the Danish/German border. Some of the almost 40 participants arrived from Italy and Spain just for the meeting. Not to speak about contributions from people who stay in Germany for longer. This confirmed us in our decision to also keep the organisation of the oemof association in English. (Side node: It was in the middle of the association’s general assembly that we realised that the about ten persons joining that particular session were able to understand German.)

Special thanks also go to Simon and Uwe for the organisation, and to the Department Energy and Environmental Management for hosting the meeting at the Europa Universität Flensburg.
