GreenLys

A project experiment with the contribution of smart grids to the electricity system in urban areas equipped with Linky

 

Number of customers concerned:

  • 1,000 residential customers and 40 tertiary sites

 

Total budget:

  • €37 million, including €10,6 million funded by Enedis

 

The Greenlys project offers two demonstration platforms in Grenoble and Lyon, for testing a wide range of smart grid functionalities in urban areas. The project is structured around the Linky smart meter, an interface between the distribution power grid (upstream) and customer’s home (downstream).

Scope

  • Demand management / peak shaving
  • Installation of innovative equipment (observation, control)
  • Gestion of ev charging station
  • Big data management
  • Power demand and generation forecasting models and tools
  • Advanced functions for managing the grid (status estimation, voltage regulation, self-healing, demand / production balance, active management of distributed resources...)

 

Key stages

Individual curtailment capacities characterized and a coordination required between the DSO and demand response aggregators

  • Observation of a power rebound of 25 to 50% of the curtailed power and an energy report of 95% of the curtailed power
    Individual curtailments of 300 LV clients graph: power rebound and energy report
  • In order to anticipate and manage the risks of a concentrated activation of flexibilities in certain locations, coordination required between the DSO and demand response aggregators
  • The panels method via Linky convincing (performance, neutrality) for the control of the achievement of the residential curtailments

Innovative solutions for the LV network observability and control implemented

  • Additional software solutions based on Linky smart meters (LV incidents management, default detection, optimization of the quality of supply) in the industrialization process
  • Testing of solutions enabling the increase of the LV network capacity:
    • LV state estimator
    • LV voltage control
    • demand response forecasting management
    • MV/LV automated substation
    • Fisheye camera to forecast photovoltaic generation
