Pioneer region for Smart Grids in Vorarlberg: Smart voltage control at the DG-demonstration grid

DG demonstration grid – concept

The team which worked on this project has developed four innovative, smart concepts for the control of the voltage within the supply grid. With these concepts, the supply voltage can be stabilized and also ensured in periods with an intensive feed-in of decentralized supplying plants (for example photovoltaic plants). These control concepts, this was found out in examines, have a higher economical potential than methods to stabilize the energy transfer, which are nowadays common used (for example line driving).

BAVIS – Support of an active grid operation by an innovative voltage control

The goal of this project was to improve the concepts for voltage control which have been developed within the project DG DemoNetz. For different conditions, which depend on the intensity of the destabilization of the supply voltage and on the characterization of the grid, different control concepts are recommended. These control concepts allow a more efficient use of the grid (for the grid operator as well as the customer and supplier) and a more unproblematic use of the existing grid infrastructure.

DG Demonetz Validation

Within this project the concepts for voltage control, which have been developed within the projects DG DemoNetz and BAVIS, have been implemented at grids in Salzburg and Vorarlberg and are tested in relation to their practical suitability. Currently the project is still running.
