Examining the behaviour of a small-scale power grid subjected to variations in production and use, supply electricity to an isolated area, or facilitate behaviour that helps the energy balance of a quasi-energy-autonomous district.
Concept Grid is a genuine smart distribution network designed to anticipate and support the change of electrical systems to smart grids.
Located at the EDF Lab Les Renardières site in Seine-et-Marne, Concept Grid makes it possible to safely conduct full-size test campaigns in very different domains, ranging from the primary substation to the customer. Over three hectares, Concept Grid has 10km of overhead and subsurface networks, two distribution stations, test labs, fully-equipped houses, smart meters, photovoltaic panels, wind turbines, charging points, etc.
Among its many benefits, Concept Grid makes it possible to run complex "stress tests" in degraded conditions that would be impossible to carry out in situ, with actual customers.
Located in the Carros, Alpes-Maritimes, area, NICE GRID is a smart solar district test-bed, with:
a large proportion of local photovoltaic generation;
electricity storage solutions;
2,500 Linky communicating meters; and
demand-side management solutions to improve how peak loads and/or electrical production on different timescales are managed.
EDF's part is to get customers to change their behaviour and get them involved in their own power consumption. It involves, in particular, inciting customers to delay or smooth out their peak consumption period, or to use storage capacities during periods of high photovoltaic production, to help incorporate this production into the local grid.
At the heart of Cirque de Mafate on Reunion Island - a World Heritage Site - the aim of the project is to connect several buildings together by fitting them with solar panels coupled to a Smart Autonomous Green Energy System (SAGES) station. The hydrogen-technology energy storage means they will benefit from a continuous source of electricity from renewable sources, day and night, and irrespective of weather conditions. Setting up such a microgrid without a diesel generator set is a step towards decentralised generation and consumption of clean, reliable energy, particularly suited to isolated sites and communities.
