Main results

Total budget:

€27 million, including €1,4 million funded by Enedis

SOGRID is an industrial project led by Enedis and STMicroelectronics in a consortium of 10 partners in Toulouse, officially launched on 11 April 2013. The project will mobilise over a hundred stakeholders, researchers and industrialists up to the end of 2015.

Scope

Installation of innovative equipment (observation, control)
Advanced functions for managing the grid (status estimation, voltage regulation, self-healing, demand / production balance, active management of distributed resources...)
Communication systems and protocols

Key stages

G3-PLC communication

Good potential of the G3-PLC communication technology performances, from LV meters to HV/MV substations in urban area (flows, latencies, robustness)
Implementation of existing operational functions (remotely controlled device, data collection, etc) with extended capacities through a secured G3-PLC chain PLC communication system
Communication enabled in rural area all along the network but with a limited bandwidth

LV real time network state estimator

LV network state update every 10 minutes that can be set to 5 minutes
Estimating calculation algorithms needing a large range of measures and the optimization of the selected points and of the model choice of the electrical system
Realization of the voltage profile of the LV cluster (mean error of the measures < 1%) and of the corresponding MV/LV transformer load (power measures)

Real time LV network control service
