1. A wind power plant for providing electrical power to a utility grid, the wind power plant comprising:
at least one wind turbine having a wind turbine generator coupled to a wind turbine rotation shaft to which plural rotor blades are mounted, the wind turbine providing electric power at an output terminal;
at least one power conversion system, each comprising:
a plant motor electrically coupled and configured to receive the electric power from the output terminal of the at least one wind turbine and convert the received electric power into rotational power of a plant motor shaft;
a plant generator mechanically coupled to the plant motor shaft and electrically coupleable to the electric utility grid;
wherein the at least one of power conversion system further comprises:
a power conversion system controller being configured to control active power at a power conversion system output terminal based on at least one reference value related to the utility grid;
wherein the power conversion system controller comprises a plant motor controller communicatively coupled to the plant motor and a plant generator controller communicatively coupled the plant generator; and
wherein the plant motor controller is configured to receive a plant active power reference signal, to determine individual active power reference signals for the at least one wind turbine and/or at least one power generating component based on the plant active power reference signal and supply the individual active power reference signals to the at least one wind turbine and/or the at least one power generating component.
