Report from the anniversary meeting

The last days, we had our semi-annual meeting to discuss the state of open energy system modelling. This time in the flavour of a user meeting with a special 10-year celebration event. I am so happy that I can tell that the concept worked out: We had almost 40 guests, some of them were on their first oemof meeting. Still, they dynamically formed sub-groups for parallel sessions, had fruitful discussions, shared experiences, and eventually started implementing something together. To kick this off, we asked every participant to give a short pitch at the first day. This was quite a ride, but due to coffee breaks and a poster session in the DLR entry hall, it was possible to identify many persons you wanted to talk to later.

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?

Things to come

Hack, eat, sleep, repeat: Our 2022-11 dev meeting was one big hackathon event where we joint forces to solve problems with the code. It was so intense, we even forgot to taka a photo. (We were some 15 very enthusiastic hackers.) There are a couple important decisions to be communicated:

The next release of solph (v0.5) is in feature freeze. We will just update the documentation and finalise making arguments explicit and release afterwards.
Multi-period optimisation and renaming Transformer to Converter will follow with v0.5.1 with a merge to mainline solph right after v0.5.0. The changed name will have a wrapper so it is not API breaking.
Stephan Günther, Caroline Möller, and Patrik Schönfeldt form the new board of the oemof association.

Also, today was an important day for the oemof association. After everything was agreed on by the general assembly on November 10th, 2022, the protocol as well as the statute were notarised and sent to the register of associations. By chance we also received the final documents needed to apply for our non-profit status. So, now we have to wait until things are processed until the association gets it final legal status.

oemof general assembly 2022/11

Hereby we invite you to the general assembly (GA) of the oemof association. It will be held at the University of Magdeburg at 13:30 on the 10th of November 2022, as a part of this year’s developer meeting (9th to 11th of November). As we elect our representatives for one year, elections are the crucial point of this GA. To get used to the standard procedure, the agenda includes all typical points even if i.e. the financial report will be really short. If you have further points to discuss, please send an email to meetings@oemof.org or post them at https://github.com/oemof/oemof/issues/105.

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.

oemof general assembly 2022/05

We invite you to a general assembly (GA) of the oemof association that will take place on the 19th of May as part of the oemof user/dev meeting in Flensburg. The assembly will be located at the meetings venue (European University Flensburg Building VIL1, Auf dem Campus 1, Flensburg) and start at 14:00.

Agenda:

Opening and welcome
Agreement on the agenda
Acceptance of the minutes of the last GA
Changed statute
Bylaws and membership fee regulations
Miscellaneous

The changed statute can be found at GitHub (binding German version, informative English translation). The changes are marginal and probably required by the German authorities. We decided to let the GA decide before the authorities file a formal complaint. Formally, the decision will be on the full (changed) statute rather than the changes, as it makes live easier to have everything in one protocol. According to our statute, all members can already vote on the changed statute. To do so, you can leave a review (approve/object) at the PR at GitHub. Alternatively, you can write an email to patrik.schoenfeldt@dlr.de to get instructions how to vote by (paper) mail.

2021-12: dev meeting retrospective

This years developer meeting was a hybrid format with a local and a virtual participation possibility. On the first day, the founding meeting of omoef the association was held. In addition, the statutes were voted and a board was elected. We are happy to announce that Patrik Schönfeldt, Caroline Möller and Johannes Röder represent the association and congratulate them warmly. This year we can’t provide presentations since it was a 100 % hands-on meeting. The next meeting is expected to take place in Flensburg on May 18-20. It should have a focus on application and feature development. The next winter meeting will take place from November 9-11 in Magdeburg. There the focus will be again on Maintainance and Developing.
