Hi all,

The powsybl-gse that provides a JavaFX GUI on top of powsybl is not maintained anymore. Our strategy trend towards a web-based (ReactJS) software.

The github repository has been archived so it's still available in read-only mode. We'll probably keep it alive during few months and remove it later.

Hi,

The powsybl-balances-adjustment module has been released. The balances adjustment computation consists in applying injections scaling on balance computation areas to reach target net positions. This is an iterative computation based on a power tool, commonly used in a merging process.

You can find a more complete description in the release notes.

Hi,

I'm proud to announce the first release of powsybl-iidm4cpp, a C++ implementation of the IIDM data model. This library can be used under Linux, MacOS or windows, and provides all the key features of IIDM.

This version support XIIDM v1.0 only: the support of all new XIIDM versions will be available soon. You can follow our roadmap using the GitHub projects.

Hi,

Many communities are considering renaming the default branch name of their repository from master for two main reasons:

1. master is not easily understood by people new to Git, and is not a ubiquitous term in technology (master is more easily associated with primary/secondary configurations)
2. master has multiple meanings in English, including master/slave. Although Git does not use master/slave terminology, such terminology was common until recently. Use of master/slave terminology has been removed in recent versions of many major software projects because it is not technically descriptive, precise, and avoids needlessly referencing the painful history and impact of human/slavery which continues to be felt by people all over the world.

Since October the 1st, the default branch for newly-created repositories is now main, which is the most popular replacement for master (see GitHub announce). GitLab also choosed main but considered default (used by mercurial), and excluded primary, develop, trunk, stable, release, base and root. You can find the reasoning on gitlab.com.

Before taking a decision, we would like to do a survey of our community to know if we should switch to `main` for all our repositories or we should keep the current configuration.

Hi Serkan,

thanks for reaching out ! We are always happy to share our work.

Unfortunately, the powsybl project doesn't have a graphical editor for creating networks. However, some time ago, one person made a prototype to do exactly that. You can see his work here: https://github.com/powsybl/powsybl-incubator/pull/204 

Maybe you could collaborate ? Attached is a video of creating a network from scratch that Cesar did at the time.

Others in the list can maybe give your more info!

Cheers,

Jon

Hi,

The repository powsybl-single-line-diagram contains only the low level component that is reponsible to generate a static svg from a network model. The SVG has been designed to facilitate an integration into a higher level component (like an editor): it is structured (using SVG groups) and an additional metadata file (metadata.json) is used to link graphics to network model.

There is also a downstream project call GridSuite which is an open source project (but not under le LFE) based on powsybl (including single line diagram component) that might interest you.
The Github repo is here: https://github.com/gridsuite.
Several applications are developped in GridSuite and one of them is called GridStudy: it is a study mode (under developement, so basic right now) that will allow to load a network, apply modifications, run simulations, see results, etc.
You can test it if you want with the online demo https://demo.powsybl.org/gridstudy/. You can login with you github account for instance (or any kind of microsoft account).
You can also see a demo of this application with real data on youtube: https://youtube.com/channel/UCc2C5LE9EH-Lp34ASUm5T1A

So in this tool, we have integrated the single line diagram component of powsybl, you can test it by choosing a voltage level on the left side of the application and clicking on it. You can also change the topology of a substation and see an update of the switch position and topological coloration (open the MicroGridMerge study and open PP_Amstredam 220Kv, the substation has a coupler that you can open or close). So currently we are only able using the single line diagram component to animate the SVG with a topology change or a power flow calculation update but our goal is also to be able to graphically change the structure of the substation (like add a new transformer or any other equipment) and export back the original case with the modifications (so for instance the original CGMES imported into the study with added equipments). So what your are describing will be one day possible with GridSuite but we don't known when...

Best,
Geoffroy
