Name and Location
Smartgrid Gotland demonstration project, Sweden.

Client
The project is a joint venture between Vattenfall, ABB, Gotlands Energi, Svenska Kraftnät, Schneider Electric, the Swedish Energy Agency and the Royal Institute of Technology.

Project Description
The project intends to develop strategies for the planning, construction and operation of a fully developed, large-scale Smart Grid, including a large share of intermittent production, primarily from wind power in the distribution network.

New market models and services will be developed to pave the way for new market players.

Through this development of the future smart distribution grid, consumers and producers will be fully integrated into a demonstration project that is likely to become an international model for a long-term sustainable electricity power system.

The project includes the construction of a 10 kV smart substation in the village of Källunge, on the Swedish island of Gotland, which will use state-of-the-art switchgear technology.

Latest Developments
ABB is building the smart substation. The substation will use state-of-the-art switchgear technology based on ABB’s unigear digital concept.

To process data from this substation and the rural grid, ABB is customising and delivering an advanced distribution management system (ADMS) and Supervisory Control and Data Acquisition system.

ABB is also installing switches equipped with safety and feedback functionality and equipping disconnectors with new remote surveillance and control capabilities. The ADMS will also locate and isolate fault zones from the rest of the grid and reroute electricity to minimise the impact on consumers.
