ETIBLOGG was represented at the digital conference PCIM Europe 2020

Hannover 27.07.2020

Like so many conferences, PCIM Europe took place digitally this year in July 2020. PCIM Europe is a leading international trade fair and conference for power electronics, intelligent drive technology, renewable energy and energy management. Representatives from industry and science meet here to find out about new trends and developments.

ETIBLOGG was part of Fraunhofer IISB’s guest contribution titled “Four Switch Buck / Boost Converter to Handle Bidirectional Power Flow in DC Subgrids”. The conference lecture was about the development of a non-isolated DC-DC converter, which is also used in the ETIBLOGG Demonstrators.

In the ETIBLOGG demonstrators, this DC-DC converter is used to control the power flow between battery systems according to blockchain-based trading. The converter can run in stand-alone mode as well as by parametrization via CAN-Communication and thus can control the bidirectional power flow in DC-microgrids, both in single and parallel configuration. Next to current and voltage regulation, a MMPT-algorithm (Maximum Power Point Tracking) is implemented, enabling the connection of photovoltaic modules. Experimental results show a maximum power of 300W and a peak efficiency of 97%.

Further information on the research results and the associated documentation by Schulz, Matthias, et al. Four Switch Buck / Boost Converter to Handle Bidirectional Power Flow in DC Subgrids. Proceedings of the 2020 PCIM, Nuremberg 2020 can be found here.

Back to School – ETIBLOGG joined SSW’s summer school

Hannover 08.07.2020

From June 23 until July 3, a summer school organized by Smart Service Welt supported by Federal Ministry for Economic Affairs and Energy took place – of course, representatives of ETIBLOGG participated. The online event contained 17 workshops on eight days with about 70 participants altogether.

In the case of ETIBLOGG, the workshop concerning UX Design was particularly interesting. Every project got the task to carve out their own customer journey then presenting it. ETIBLOGG gained a lot out of the feedback from the other participants.

Another formative subject was discussed in workshops about data security. A new and practical Norm ISO 27701 was presented, which can integrate data security in management systems. Also, the summer school dealt with talks about monetization of data and AI-models.

All in all, our ETIBLOGG-team had a great time joining the summer school. The event is a great showcase of a functioning virtual exchange as well as a possibility for further education. Thanks to accompanying research of Smart Service Welt for organizing – we learned a lot, had fun, and look forward to joining the next virtual classroom.

Does Corona affect ETIBLOGG?

Hannover 29.04.2020

Covid-19 decides on our lives since several weeks now. In Germany, meetings with friends are not allowed – social distancing it is called. The financial damage for the country and even worldwide is tremendous. But what about ETIBLOGG?
Of course, we are affected by the virus as well as everyone else. For the third and last project year we planned to visit several trade fairs like the Hannover Messe and other events. As all bigger events are cancelled until the end of August, this will not happen in the next months. Luckily, we can present ETIBLOGG via videoconference. If you are interested in such a meeting or just want to ask us some questions about ETIBLOGG, you can still do it via mail – so do not hesitate to contact us: info@etiblogg.de
Communication between our team is completely virtual since some weeks. But as our partners being distributed all over Germany, we used this kind of communication before. Therefore, we are already used to GoToMeeting, Teams or WebEx.
Until now, the virus does not affect the further workflow. Despite the limitations, a user case at the Fraunhofer Institute IISB should be implemented as a real demonstrator. However, as the institute’s laboratories are currently restricted and can only be entered with strict precautions, the technical implementation still has to wait. Yet, all other steps can be carried out as planned and we are optimistic that we will successfully complete the last project year of ETIBLOGG.
We are happy to be able to continue working on ETIBLOGG as planned before. Nevertheless, we hope for everyone to get through the current time safe and sound and that we will be able to meet again soon.

Two years of ETIBLOGG – what has happened so far

Hannover 01.04.2020

Today is the second anniversary of ETIBLOGG. An exciting year has passed by! What we have done so far? Here is a little summary:

  • We reached the next two Milestones. This includes an evaluation of various approaches for the hierarchical structure of the Blockchain cloud on a technical basis. Furthermore, the trading framework and the design of processes and interfaces were created. All of the findings from the milestones have been applied to our demonstrator in Erlangen or to our mobile demonstrator “Eddi”.
  • The fair demonstrator ‘Eddi’ was first introduced at EUW.
  • Since July, we have a profile on LinkedIn! You don’t follow us yet? Well, better late than never. Click here for our LinkedIn profile!
  • In the last year, we attended two trade fairs, eight workshops, hold 16 speeches and had so many exciting talks – thanks again for the great interest in ETIBLOGG!
  • In the frame of the EUW in November 2019, we created a flyer. You can have a look at it here.
  • Our whole website got a new look! Since July 2019 there is also an English version.
  • We also made a project film in Hanover and Erlangen, to see here and we participated at events in the Smart Service World II, such as the event “Tage der digitalen Technologien”.

We look back on two great years of ETIBLOGG – and also, we look forward for another exiting year!

Simone Gitschier from the consortium leader GETEC ENERGIE participated at “Was bewegt Startups?” at the Chempunkt in Dormagen. During the event, organized by Markus Quenter from the local union for middle-class and economic (Mittelstands- und Wirtschaftsunion in Rhein-Kreis Neuss), ETIBLOGG and three other startups were presented. After a short welcoming speech, a panel took place regarding the ideal choice of location for startups. The participants, representatives of each startup, discussed several aspects for this purpose. Some of them were:

– Is proximity to universities and research institutions important fir startups?
– Do funding programs from municipalities and cities play a role?
– How should support for regulatory frameworks look like?
– Is the location important for the startup at all or can everyone communicate with each other digitally?
– How should a location look like?

Afterwards, an energy-panel took place, in which every participant could present its project in detail. During a get-together in the end ETIBLOGG introduced the demonstrator to the visitors. They showed a high interest in experiencing the blockchain-technology live. More about the event’s program: https://chemlab-nrw.de/events/detail/was-bewegt-startups/

ETIBLOGG at the European Utility Week – a review

Paris, 12.11.2019 – 14.11.2019

From Tuesday, 12th of November until Thursday, 14th of November 2019, the European Utility Week (EUW) took place in Paris. Around 10,000 visitors and 350 exhibitors came together. During the three days of the trade fair, innovative inventions and projects concerning intelligent solutions for the local energy trade were presented – ETIBLOGG being one of them.

Presenting the blockchain demonstrator
At the trade fair booth (L149) of Smart Service World II, projects included in the respective technology program were presented. The ETIBLOGG project proudly presented its trade fair demonstrator. The ETIBLOGG demonstrator is a mobile system simulating a micro grid consisting of local participants. The demonstrator’s three battery systems simulate the local participants’ energy production and consumption. The first battery represents a photovoltaic plant as a producer, the second one symbolizes a consumer, for example a bakery, and a third one acts as a classic prosumer with a home storage system. Visitors could observe the energy exchange as visualizations on a nearby screen. The ETIBLOGG team answered questions of booth visitors and explained more details of the project.

Another possibility for the visitors to learn about ETIBLOGG was Michael Merz’ talk on Wednesday, 13th of November. The presentation “ETIBLOGG – Real-time energy trading in local grids” was about the current status of the research project, the participating partners and what the project’s next steps. The audience’s great interest in this talk is yet another example of the great relevance and need for sustainable and future-oriented energy supply solutions.

While the trade fair took place, we updated our followers on LinkedIn almost every day. Follow us there, so that you don’t miss any news: https://www.linkedin.com/company/etiblogg

After the first half of the research project ETIBLOGG the team presents the demonstrator at the European Utility Week trade show

Hannover, 06.11.2019

Five companies and three research institutes cooperate on a blockchain-based solution to fully automate the real-time-trade of small quantities of energy. The aim is to implement a local and net-usable energy trade. Therefore, a blockchain device (BCD) has been developed to help establish an intelligent connection from the market to the physical reality. For this to work, every member in the market needs to connect via a BCD with the peer-to-peer-network. Current plant parameters such as photovoltaics or the charge of a battery can be processed to trade-relevant information via the BCD. Based on this information, participant-specific purchase or sales orders can then be placed on the local energy market. In addition, it is possible to use market data for plant control which can result in business benefits for the participants. At the same time, however, network-related flexibility potentials can also be achieved, which are becoming increasingly necessary, especially in the continuous expansion of renewable energies.

Building of the trading fair demonstrator

The ETIBLOGG demonstrator is a mobile model system acting as a micro grid consisting of local participants. Their producing and consuming behavior is simulated by three battery systems included in the trading fair demonstrator. The first battery represents a photovoltaic plant as a producer, the second one symbolizes a consumer, for example a bakery, and a third one acts as a classic prosumer with a home storage system.
To perform the real-time energy trade via blockchain, fully automated trading agents come into action. These can be configured individually and represent every market member. The trade then takes place via a blockchain-based P2P-network. After the trading process has been completed, the BCD initiate a plant control and therefore the physical exchange of electricity between producer and consumer.

Presenting the demonstrator at the European Utility Week (EUW)

ETIBLOGG is part of the Smart Services World II booth (L140) at this year’s European Utility Week in Paris. Visitors can observe the physical exchange and trade of small energy amounts via blockchain technology between the mock-up microgrid users live at the booth. The data exchange between electricity producers and consumers is displayed graphically on a screen. What’s new is that the visitor can see the blockchain processes illustrated by a hands-on example set-up: If the photovoltaics unit produces electricity, it sends a respective sales order into the blockchain. A consumer – such as a bakery – can accept the order via the blockchain and cover its electricity needs. In a next step the electricity is delivered physically.
In the second project phase, ETIBLOGG plans to implement the lessons learned from this demonstrator setting to a real live application – a so-called real-life lab.

ETIBLOGG application Areas

The technological findings from the ETIBLOGG project can be applied to trading electricity locally. This contributes to avoiding local bottlenecks in the electricity infrastructure and reduces the need to export and import electricity from higher network levels. Additionally, ETIBLOGG enables the isolated operation of microgrids.
Depending on the exact set-up, the participants can for example be electricity producers (renewable or fossil based), consumers or third-party traders, offering surplus energy on spot markets and managing balancing groups of different market participants.

Project participants

ETIBLOGG consists of several companies and research institutions from all over Germany. Every single one of them is contributing their expertise to the ETIBLOGG project. Consortium leader is GETEC ENERGIE GmbH from Hanover. The other project partners are: Consider it GmbH, ESMT Berlin, Fraunhofer IISB, Mixed Mode GmbH, NXP Semiconductors Germany GmbH, PONTON GmbH and the University of Hamburg.

You are welcome to visit ETIBLOGG at the booth of Smart Services World II (L140) during the European Utility Week. You can also contact us before the trade show and make an appointment.

Meeting of ETIBLOGG consortium on October 14th, 2019

Hannover, 18.10.2019

On October 14th 2019, the ETIBLOGG consortium meeting took place in GETEC ENERGIE’s headquarters in Hannover. In addition to the eight project partners, representatives of the project sponsor DLR and accompanying research were present. The aim of the meeting was to present the results and experiences of the past months to all participants. Thus, each leader of the six work packages presented the goals, milestones, outcomes, risks, and the next steps in detail to the participants. Additionally, the involved scientific research institutions presented their first results:

– Functional test environment at Fraunhofer IISB in Erlangen
– Creation of a requirement catalog and associated goals to test the demonstrator
– Overview of the actual standpoint of the blockchain -technology
– Report regarding the blockchain-implementation
– Establishment of the trading framework and the specification of associated intersections

In addition, the ESMT presented the first results of the qualitative interviews to the business models. The University of Hamburg gave first insights into the bibliometric analysis regarding “Blockchain & Energy”.
The major highlight of the consortium meeting was the presentation of the trade fair demonstrator which will be presented in more detail to a broad expert audience at the European Utility Week trade fair in Paris in mid-November. The trade fair demonstrator’s objective is to tangibly illustrate the connection between controllable plants and trading via the blockchain using the blockchain devices. A small and independent microgrid – consisting of three batteries and associated blockchain devices – is set up within the trade fair demonstrator. During demonstration, the blockchain devices – consisting of standard Raspberry Pis – control battery systems and precisely set predefined load curves. The integration of the trading logic is the next important step in the following days to complete the trade fair demonstrator. Then, a real-time trade in small quantities of electricity via Blockchain technology can physically be tracked at the trade fair demonstrator.
In the concluding part of the meeting the members learned about the procedure regarding the transfer of the results and the public relations activities. The next steps were discussed together. Before going on to the final question round, the accompanying research presented the past and upcoming activities.
The meeting showed every participant that the project ETIBLOGG is implemented successfully so far. The consortium looks forward to the next steps within the project. Subsequent to the meeting, the project team executed integration tests with the focus on implementing the trade logic on the single Blockchain devices.

ETIBLOGG joined the Accelerator Days 2019

Berlin, 13.09.2019

ETIBLOGG participated on the Workshop „Querschnittsthemen der Smart Service Welt II“ which took place on 13th September 2019. The focus of the event was on legal as well as IT security aspects. One workshop explained how data protection and other information security can be combined in a company. In the workshop “Information Security in Digital Platforms” each project had the opportunity to limit its own digital platform to the individual core elements. The ETIBLOGG team then asked themselves what the requirements for relevant core modules (e.g. cloud infrastructure, blockchain technology) and what the security measures to minimize threats are. To conclude, there was an insight into the former GDPR and initial information on the e-Privacy Regulation. In between there was again a lively exchange among all SSW II projects and the accompanying research.
