SOGRID is an industrial Smart-Grid demonstrator project led by ERDF and STMicroelectronics, in a consortium of 10 partners (Nexans, Sagemcom, Landys & Gyr Capgemini, Trialog, LAN, Grenoble-INP, LAN and Ecole Polytechnique).
Context
The demonstrator is part of the electricity grid in Toulouse, where the project was officially launched on 1 April 2013. The SOGRID project stems from the call for expressions of interest in smart grids, issued by ADEME (French Agency for Environment and Energy Management). Initiated in 201 within government program “Investissements d’avenir”, it was approved by the French State in 2012.
Why SOGRID?
This experiment is part of a comprehensive approach aimed at
developing smart grids, in particular a full G3 and IPv6 end-to-end communication chain over power distribution grids thanks to PLC technology (powerline communications).
In what way is this a ground-breaking project?
The SOGRID project will make it possible to develop a next-generation microchip and to equip many devices connected to the power grid. It will permit point-to-point communication and thus create a Smart grid.
What are the stakes?
With SOGRID, the ambition of the consortium’s partners’ is to test and further an international communication standard based on PLC technology, which will help boost an industrial sector of excellence in France.
Our Contributions
We present a mathematical modelling and a solution approach to determine the number and placement of measurement devices and repeaters that minimize the total measurement cost and ensure the convergence of the state estimation function considered as well as the satisfaction of telecom and G3 PLC constraints.
A routing protocol, LOADng (The Lightweight On-demand Ad hoc Distance-vector Routing Protocol – Next Generation), is developed to enable ecient, scalable and secure routing in such constrained en- vironments. As a reactive protocol, it does not always keep a routing table for all destination, but generates routing messages only when there is data to be sent in the network, to reduce routing overhead and memory consumption. Designed with a modular approach, LOADng can be extended with additional components for adapting the protocol to different topologies, traffic and medium characteristics. LOADng has been ratified as the routing protocol for G3-PLC (G.9903) recommendation.
