Synchronous grid of Northern Europe explained

The Nordic regional group (formerly NORDEL) of ENTSO-E is a synchronous electrical grid composed of the electricity grids of Norway, Sweden, Finland and the eastern part of electricity sector in Denmark (Zealand with islands and Bornholm). The grid is not synchronized with the synchronous grid of Continental Europe, but has a number of non-synchronous DC connections with that as well as other synchronous grids. Gotland is not synchronized with the Swedish mainland either, as it is connected by HVDC.^{[1] [2]}
