Robert Tusveld, Solutions Architect at Dutch distribution system operator Alliander, introduces Grid eXchange Fabric (GXF), an LF Energy project. Robert will offer an overview of GXF’s history, followed by a deep dive into the technology along with use cases, and a Q&A session at the end.
Formerly known as the Open Smart Grid Platform, Grid eXchange Fabric (GXF) allows you to monitor and control hardware in the public space. With several (generic) functions ready to use, the main benefits of GXF are: scalability & high availability, high security, its generic design, and no vendor lock-in. GXF has several working use cases, including microgrids, smart metering, public lighting, and distribution automation.
Register in advance and join us for the webinar on April 21, 2020 at 6pm CET, 9am PDT. See you there!

On January 13-15, 2020 in Paris, France, a team of IT specialists at the transmission and distribution level engaged in a collaborative coding event to create open source software for asset monitoring. RTE, Alliander and TenneT worked together through this three-day immersion to learn more about each other’s projects and to gain understanding about joint investment and how to leverage each other’s software talent for faster innovation and uptake.
Curious about the results? Have a look at the daily reports:
Day 1 begins Monday morning at a beautiful location on the famous Champs-Élyseés in Paris. For the next 3 days this will be the home base for the open source collaboration between RTE, TenneT and Alliander. After getting to know each other and some short presentations it is time for the daily stand up. We gather around a full kanban board and divide the tasks. After everything is hooked up and all systems can be accessed it’s time to get started, here we go!
In order to make sure all applications can communicate seamlessly, collaboration between the developers is crucial. It immediately becomes apparent that this is why we came to Paris. After a nice lunch and a walk around the Arc de Triomphe it’s back to an afternoon of coding. The hard work pays off and by the end of the day we are able to celebrate our first success! Simulated messages are collected by Grid eXchange Fabric (GXF) and published on Kafka, ready to be picked up and processed by the other applications. And that’s exactly what will we do, tomorrow. On to day 2!
Despite the ongoing strikes everybody manages to reach the location on Tuesday morning. With a cup of coffee and a fresh croissant in hand, the day starts with a mini retrospective. The retrospective reveals that everyone is very happy with the way we are working together and they are eager to get started on another day of coding. But it’s not all good news as a technical challenge presents itself. For some reason Spark in combination with Kafka, needed for the data analysis, doesn’t seem to be working. The daily stand up is used to discuss how the problem can be solved and then we get started. When it’s almost time to go for lunch the problem still isn’t fixed. But there is other good news; OperatorFabric is now able to display the messages that are posted on Kafka by GXF. This means the first two open source programs are coupled!
After lunch a couple of options to get the analysis part working are discussed. A group of developers gathers around a whiteboard, draws up a solution and sets out to realize it. Meanwhile preparations are being made for tomorrow’s demo. There is not a lot of time left, what will be able to show? We’ll find out tomorrow, on to day 3! But not before day 2 is ended with a nice group dinner.
Even after Tuesday nights dinner, everyone manages to be at the location in time for the third and final day of coding. Thankfully, because there is still a lot to do. We agree to stop coding at 11am in order to do a dry-run in preparation of the demo. While the deadline moves ever closer, Olivier Grabette, member of RTE’s board of directors, shows up to show his support to the developers and the open source way of working.
At 11:30, 30 minutes later than planned, the last tasks on the kanban board are moved to ‘done’, it’s time for the first dry-run. Doing this final rehearsal turns out to be a good idea as the analytics solution (without Spark) doesn’t quite seem to be working the way we want it to. The developers set out for the final push and with just a minute to spare the traffic light turns green, then orange, then red, success!
After establishing the online connections for the audience back in the Netherlands the demo is started. After a short introduction on the ‘what’ and ‘why’ of this shared coding event it’s time to show the results. With more than a 1.000 messages per minute, several days of transformer load and temperature values are simulated. The values are displayed on a substation diagram in real-time. In the diagram, next to the transformers, are also 2 traffic lights which indicate the status of the transformer. On day 3 of the simulation 1 of the transformers starts to show anomalies. The measured temperature does not correspond with the value expected in the analytics and the traffic light turns orange. As the value further deviates the traffic light turns red. At this time the system operator is notified through notification in OperatorFabric. This open source application shows a timeline with relevant notifications for the system operator. The application allows him to open the notification and see all relevant information associated with this notification.
The demo is concluded by looking back on the past 3 days of collaboration. It is clear that being together in 1 location was really valuable and further opens source collaboration holds a lot of potential. While everyone speculates on the location of the next collaborative coding event it’s time to thank each other and say goodbye. Until we meet again, maybe at the open source bootcamp at Alliander on February 6th.
This is a great opportunity for a free full-day training on working in open source. The event is Feb 6 in Arnhem, Netherlands.
On January 13-15, 2020 in Paris, France, a team of IT specialists at the transmission and distribution level will engage in a collaborative coding event to create open source software for asset monitoring. RTE, Alliander and TenneT will work together through this three-day immersion to learn more about each other’s projects and to gain understanding about joint investment and how to leverage each other’s software talent for faster innovation and uptake. They plan to work with a use case based on LF Energy’s open source projects OperatorFabric, RTE’s Plasma, and Alliander’s OSGP, which was recently transferred into LF Energy and is in the process of changing names. In addition, the team will explore TenneT’s Data Platform for additional functionality.
This promising cooperation provides opportunities for speeding up the pace of innovation in development by finding ways to address present and future challenges presented by the energy transition.
The main goal of this particular live, in-person coding event, is to show the ability to transport data generated in a simulator through OSGP middleware and Kafka, and display it in a substation diagram, perform basic analytics and generate an alert on deviation. In these three days, the scenario will be based on a single location and will use fictional data. The use cases are:
- Gather data from 2 transformers using the 61850 protocol (Active power and Oil temperature)
- Display a real time view of the substation hosting the 2 transformers.
- Analysis of the thermal behavior of the transformers
- Alert through OperatorFabric in case of thermal deviation, and highlighting in the substation view of the defective transformer.
The European power grid companies are all making active investments in open source development. Based on open source and a permissive reuse license, RTE, TenneT and Alliander are starting a number of projects such as asset monitoring (data driven network management) and the Digital Substation project. The open source innovations aim to foster international cooperation for power grid companies through transparent cooperation. The projects are hosted by LF Energy.
Thanks to everyone who joined us for the LF Energy Global Summit 2019 in Paris, France. The event was a huge success in bringing together luminaries from the open source and energy communities.
Of course this would not have been possible without generous contributions from our sponsors: CNCF, RTE, Vanderbilt University, the National Renewable Energy Labs, and the FREEDM Center at North Caroline State University.
In addition, every single speaker contributed their time, energy, and wisdom to make this event a success, and we thank you from our hearts. As Shuli says: Part of the value of being associated with the Linux Foundation and the open source community is that on principle, we are a group who fundamentally believes in the power of together. Indeed, if we as an industry can continue to ask for help and insights from such brilliant and legendary practitioners, we will be able to achieve decarbonization, because we will be able to go faster with their help. Much thanks to all.
Presentations from the event can be found on the presentations page. We are working on the recorded videos, which should be available soon.
