Smart Grid Laboratory – “Concept Grid”

Concept Grid is a new experimental platform inaugurated in 2013 and designed to support and anticipate the evolution of electric systems.
Its unique design places it mid-way between laboratory tests and experiments in the field, to conduct, in complete safety, complex testing campaigns that would be impossible to perform on a real network.
Main circuits: MV and LV networks (underground cables, overhead lines), 3 secondary substations, 3 neutral point treatment, fiber optics for I&C (61850) and advanced smart functions
Sources & Loads: PV, wind turbines, storage systems, 5 houses, EV terminals, motor/ generator (50 kVA), 4 quadrants LV amplifier (120/60 kVA) + real-time simulation
Functions:
Real-scale studies, MV short-circuits, LV disturbances (voltage, harmonics, current, etc.), Power HIL, Microgrid, Telecommunications
Tests on:
Electric & IT equipment, Storage systems, Electric vehicles, Smart home, Smart meters, DER, Algorithms (EMS, etc.)
