Grids − Energy interlinked


The fluctuating in-feed of power from renewable energies means that networks are subject to large loads: Originally designed for the transport and distribution of centrally generated power, they now need to be transformed into collection networks, because ever more consumers are simultaneously becoming generators.

To ensure that the customary high security of supply is not jeopardised and that voltage fluctuations remain within permitted limits, network operators require precise information on the behaviour of the decentralised feeders in relation to the network parameters. It must also be clear what maximum outputs will be in-fed, and that a system will not disrupt the network operation.

TÜV NORD supports feeders with type and project certifications, and enables them to have unobstructed, secure access to the network. With our interdisciplinary support in grid development, we offer network operators a comprehensive range of services:
