Method and controller for continuously operating a plurality of electric energy generating machines during a high voltage condition

A controller for continuously operating a plurality of electric energy generating machines during a high voltage condition at a point of common coupling of the plurality of electric energy generating machines, the controller comprising:

• a receiving unit for receiving a sensor signal from a sensor sensing a voltage level at the point of common coupling exceeding a permitted voltage level;
• and
• a processing unit for curtailing an active power output of the plurality of electric energy generating machines in such a manner that a reactive capability of the plurality of electric energy generating machines is increased;
• establishing a set point of an electric quantity being present at the point of common coupling in such a manner that a reactive electric component providable by the plurality of electric energy generating machines is increased;
• and
• controlling at least one of the plurality of electric energy generating machines based on the established set point of the electric quantity in such a manner that the high voltage condition at the point of common coupling is at least partially remedied.
