CEDER-CIEMAT’s microgrid is underpinned by a 45 kV power line and serves a 45/15 kV (1,000 kVA) substation. From this substation, medium-voltage power is distributed via an underground network to eight transformer substations, which adjust the power to a low-voltage, three-phase supply delivering 400 V.
The network can operate as a ring, enabling a medium-voltage perimeter some 4,200 metres long, and also as a radial network.
All of the components that comprise the systems for distributed generation, distributed electricity storage and load are connected at low voltage.
In terms of demand, the Centre offers a number of different consumption profiles, similar to those that can be found in an industrial environment, a services environment and even a domestic environment.
