Distribution grid operation through PLC
Toulouse
2012-2016
1000 customers with Gen3 Linky smart meter, 2 primary substations, 5 MV feeders, 26 secondary substations.
OBJECTIVES
• Develop a comprehensive PLC line of command throughout the distribution grid based on Gen3 PLC.
• Testing services enabled by a “full CPL” chain of command regarding observability and manageability of power and telecoms grids.
• Develop a LV diagnosis tool addressing issues of generation/consumption balance.
• Supervise the LV grid with systems embedded into the MV/LV substation.
ACHIEVEMENTS AND LESSONS LEARNED
Grid-wide roll out ongoing
Gen3-PLC chain (downstream from the concentrator) and associated grid services validated.

Further development
needed before roll out
• Roll out of captors, couplers, smart systems on the MV and LV grids
• Implementation of autonomous decision-making algorithms in the data concentrator.
No grid-wide roll out
Use of PLC to communicate upstream from the concentrator: testing of Gen3-PLC signals’ propagation in MV in rural and urban areas (connectivity and resilience tests) – technical solution is potentially interesting in selected use-cases but scaling up costs country-wide remain high.

REAL-TIME LV DIAGNOSIS DEVICE
Real time LV grid supervision
• Potential performances of Gen3-PLC communication from LV meters to the primary substation in urban areas (speed, latency, resilience) are interesting.
• Effective implementation of operational services, whether existing (remote-controlled mechanisms, TM data, Linky functions) or new (real-time LV supervision) throughout a secured PLC chain.
• End-to-end communication of the SOGRID chain possible in rural area but with limited bandwidth.

GEN3-PLC COMMUNICATIONS
• Transmission of LV grid situations every 10 minutes, with possible setting on 5 minutes.
• Algorithms for grid assessments require sufficient arrays of measurements and an optimisation of measurement points selected and models chosen.
• Tension profile for LV clusters (weighted average with error margin < 1%) and load assessment at MV/LV transformer.
