“The tests to be conducted in the area of toulouse are the first experiment in the world of a chain of global communication on the power distribution network, up to the end-customer“, welcomes Xavier Montuelle, head of project Sogrid in Enedis. After 3 years of R&D and deployment on a one year pilot to large-scale, partners in the project Sogrid come and present at Toulouse a first report from this collaborative project carried out in the framework of Future Investments.
A consortium of 10 partners
Draft of technological and industrial research launched in 2013 in Toulouse, Sogrid is led by Enedis, and STMicroelectronics as part of a consortium of 10 members : manufacturers (Nexans, Sagemcom, Landis+Gyr, Capgemini), innovative SMES (Trialog, LAN) and academic partners (Grenoble INP and Ecole Polytechnique). The project has a budget of 27 million euros, of which 12 million euros from Ademe. It should contribute to a better real-time management of the electricity network, in the context of the energy transition.
With Toulouse Métropole, the partners of the consortium were able to test and validate the prototype of the electric network of future on the area of toulouse, thanks to a test network 35 kilometres in total. This network has built 1000 homes in the district of Saint-Cyprien in Toulouse and the nearby town, Vieille-Toulouse, to be able to work in both areas urban and peri-urban, or rural. 1000 smart meters have been deployed, along with 300 equipment connected on the network, including sensors, isolators and data-hubs, integrating all of the electronic chip of new generation developed by STMicroelectronics.
A technological success…
“For the first time, an electricity distribution network became fully digital on the map telecom, via a power line carrier of the third generation (CPLG3), the networks of low voltage and medium voltage“, insists Xavier Montuelle. Side Enedis, the balance is positive overall. “Sogrid has made a proof-of-concept for the implementation of a digital communication link on the electricity distribution network. It is a brick of important technological in the necessary evolution of the infrastructure to accompany the energy transition and the construction in France of the future smart grid, by 2030“, stresses Jean Paoletti, regional director of Enedis Midi-Pyrénées South.
…and 5 patents filed
The project has enabled each of the partners to test and validate its products or technology solutions, with ambitions in international business. In the framework of Sogrid, 5 patents have been filed : 2 to Enedis, including the synchronization of equipment via the frequency of 50 Hz and 3 for Nexans, on the low voltage dc supply for electronic devices of communication, the process of installation of communication devices on a cable of electric transport and the use of power transformers in coupling system for POWERLINE communication.
“We were already positioned on the market solutions for renewable energy. With Sogrid, we have been able to develop new offerings in industrial management telecommunications and intelligent networks“, underlines Annie Cheenne, director, Smart Grid and E-mobility at Nexans. Same goes for Sagemcom : “Sogrid will allow us to enter a new market segment, that of medium-voltage,” said Nabil Sahri, director of Business Development of the energy sector in Sagemcom. As to STMicroelectronics, the roll-on Toulouse equipment incorporating its new chip STComet accompanies the industrialization of a new line of products within its plant in Rousset, near Aix-en-Provence.
