A method using machine learned, scenario based control heuristics including: providing a simulation model for predicting a system state vector of the dynamical system in time based on a current scenario parameter vector and a control vector; using a Model Predictive Control, MPC, algorithm to provide the control vector during a simulation of the dynamical system using the simulation model for different scenario parameter vectors and initial system state vectors; calculating a scenario parameter vector and initial system state vector a resulting optimal control value by the MPC algorithm; generating machine learned control heuristics approximating the relationship between the corresponding scenario parameter vector and the initial system state vector for the resulting optimal control value using a machine learning algorithm; and using the generated machine learned control heuristics to control the complex dynamical system modelled by the simulation model.

Rotor blade with serrations

A rotor blade for a wind turbine is provided. The rotor blade includes a pressure side, a suction side, a leading edge section with a leading edge, and a trailing edge section with a trailing edge. An airflow flows along the surface of the rotor blade from the leading edge section to the trailing edge section and builds up a boundary layer in close proximity to the surface of the rotor blade. The rotor blade includes a noise reduction device for reducing noise which is generated by interaction of the airflow and the rotor blade. The noise reduction device is located within the boundary layer of the rotor blade. The noise reduction device includes a cover and connection device for connecting the cover to the surface of the rotor blade. The cover spans at least over a part of the surface of the rotor blade.

Rotor blade with noise reduction means

A noise reducing wind turbine blade is disclosed. The wind turbine blade includes a blade body having a leading edge, a trailing edge, a suction side, and a pressure side. The wind turbine blade further includes a noise reducer disposed on a portion of the blade body extending partially upstream from the trailing edge for modifying airflow over the blade body effective to reduce acoustic emission.

Noise reducer for a wind turbine blade

Apparatus for detecting aerodynamic conditions of a rotor blade () of a wind turbine (). An acoustic sensor () may be remotely located from the rotor blade. The sensor may be focused to monitor a portion of a blade path swept by the rotor blade to detect an aerodynamic condition such as flow separation, and may provide input to a controller () for control of a pitch of the blade effective to prevent the flow separation from developing into a full stall condition. One sensor may be focused to monitor blades of more than one wind turbine. A plurality of such sensors in a wind park may be connected to a supervisory controller () to predict the propagation of wind conditions progressing through the park.
