Wind turbine and wind farm

A booster wind turbine comprising:

• a power production component including at least a generator of the booster wind turbine;
• an electric assembly for electrically connecting the power production component and at least one first further wind turbine to an electric export cable, which is connectable or connected to a power grid, such that the electric assembly configures the wind turbine as the booster wind turbine,
• wherein the booster wind turbine is linked to a second booster wind turbine,
• wherein the electric assembly comprises:
• a switchgear operated on a first lower voltage level for switching and collecting input power from the power production component and from the at least one first further wind turbine, providing collective power on a first lower voltage level;
• a transformer for transforming, from a primary side of the transformer, the collective power from the switchgear to a second higher voltage level of the export cable connected to a secondary side of the transformer, and
• a second higher voltage level input and/or output interface, located at the secondary side of the transformer and operating on the second higher voltage level, providing an interconnection link linking the booster wind turbine to the second booster wind turbine, wherein the second booster wind turbine is configured to receive and/or provide power via the interconnection link on the second higher voltage level, wherein the second booster wind turbine includes a second electric assembly having a second switchgear operated on the first lower voltage level for switching and collecting input power from a power production component of the second booster turbine and from at least one second further wind turbine.
