Concept Gird is a new laboratory built by EDF R&D at Moret sur Loing (Les Renardières). Its commissioning is foreseen March 2013. Concept grid is a representative distribution network:
- Primary substation 20/20 kV with three neutral grounding possible (resistor, Petersen coil and smart electronic neutral);
- Underground 20 kV self healing loop ;
- 20 kV overhead line with coordinated automatic reclosers located at the head of the feeder and in its middle ;
- The length of the network is artificially increased thanks to resistors, reactors and capacitors units (120km 20 kV network)
- LV network fed thanks to two secondary substations:
- Variable length in order to change the short circuit power;
- Five little homes with new usages (PV , wind mills, EV, heat pumps, storage, …);
- PV generation ;
- 50kVA Motor/generator set
- 120kVA LV amplifiers able to inject electric perturbations (frequency change, harmonics, dip sags, …);
- Hardware in the loop simulation thanks to the LV amplifiers.
A communication network is associated to the power network (optic fibers, copper, PLC, radio, Adsl, …).
