Under the Smart Grid Gotland project, a high proportion of intermittent wind power will be integrated in the distribution network for upgrading other rural grids in order to lower environmental impact.

New technological solutions will be deployed to enhance power quality and project will serve as a model for upgrading other rural grids.

ABB will build a 10kV smart substation in the village of Källunge in the implementation phase.

The substation will be equipped with switchgear technology based on ABB’s Unigear Digital concept.

An advanced distribution management system and supervisory control and data acquisition system will process information from the substation and the rural grid.

ABB will also install switches featuring safety and feedback functionality and deploy disconnectors with new remote surveillance and control capabilities.

The company said the ADMS will locate and isolate fault zones from the remaining portion of the grid and reroute energy to lower impact on consumers.

ABB power systems division president Claudio Facchin said: "We are pleased to contribute our innovative technologies to helping develop more flexible and sustainable energy systems and more intelligent and efficient electricity networks."

Smart Grid Gotland project is being developed jointly by Vattenfall, ABB, Gotlands Energi, Svenska Kraftnät, Schneider Electric, the Swedish Energy Agency, and the Royal Institute of Technology.
