Webinar on grid connection of offshore wind farms

679

Published on

Grids are already developing offshore, and this development will continue even though at what pace and how they will develop is still uncertain. Indeed, there are different possible configurations for a future offshore grid: it can be a simple multiplication of standalone lines that provide each a single service (either connection of generation, or connection between transmission grids); or it can be a more integrated infrastructure like an offshore meshed grid that combines and interconnects dozens of offshore lines and generation units (hereafter combined solution).
