Zusammenfassung:	A method and a system for adjusting a wind-turbine power take-off. The system comprises: a plurality of phase current sensors and a plurality of voltage sensors operatively connected to a synchronous electric generator, an active rectifier, and a micro-controller. Instructions stored on the micro-controller, when executed, are configured to cause the micro-controller to execute the method comprising: obtaining a measurement of generator's output phase voltages; determining rotor rotation angle based on the measured generator's output phase voltages; executing an optimization algorithm to determine an optimized speed of the synchronous electric generator based on a target energy value. The synchronous electric generator is controlled based on the determined optimized speed by at least one of: setting an electromagnetic torque on a shaft of the synchronous electric generator, setting currents in windings of the synchronous electric generator, and controlling the active rectifier boost converter function operating in conjunction with a down converter.
