摘要： A method of operating a wind turbine, in particular plural wind turbines of a wind park, includes: receiving, by the wind turbine or a wind park controller, safety relevant information from an external source external to the wind turbine; activating, by the wind turbine or the wind park controller, a safe operation mode depending on the received information, wherein the external source is different from a wind park controller.

摘要： An optimal dispatching method and system for a wind power generation and energy storage combined system are provided. Uncertainty of a wind turbine output is characterized based on spatio-temporal coupling of the wind turbine output and an interval uncertainty set. Compared with a traditional symmetric interval uncertainty set, the uncertainty set that considers spatio-temporal effects effectively excludes some extreme scenarios with a very small probability of occurrence and reduces conservativeness of a model. A two-stage robust optimal dispatching model for the wind power generation and energy storage combined system is constructed, and a linearization technology and a nested column-and-constraint generation (C&CG) strategy are used to efficiently solve the model.

摘要： A method of activating and/or deactivating a safe mode of operation of a wind turbine is provided, the method including: receiving at least one measurement signal related to a weather condition; filtering of a measuring signal dependent quantity to obtain a filtered signal, wherein the filtered signal depends on whether the measuring signal dependent quantity and/or filtered signal is increasing or decreasing with time; activating and/or deactivating the safe mode of operation based on the filtered signal.

摘要： A wave energy capturing device arranged to capture and convert wave energy to useful energy when positioned in an operating mode. The device includes a pivot point and a buoyant wave energy absorber affixed to the pivot point. The device has an operating mode where the device is arranged to capture wave energy. In the operating mode the pivot point is supported above the surface of a body of water and is held substantially stationary relative to wave movement. The buoyant absorber is engaged with the surface of the body of water at an operating location positioned downwave of the pivot point and wherein the absorber is arranged to rotate about the pivot point. The rotation defining a rotation arc of the absorber along which the absorber is arranged to reciprocate in the operating mode. The disclosure aims to provide improved capture of wave energy for conversion to useful energy.

摘要： A buoyant wave energy capturing device is provided for use in a wave energy conversion (WEC) system, the device comprising: an absorber portion having a physical property linked to a hydrodynamic characteristic of the absorber portion; and wherein the physical property of the absorber portion, and in-turn, the hydrodynamic characteristic of the absorber portion, is arranged to be adjusted. The present invention aims to provide an improved energy capturing member for use in a WEC system which is less susceptible to damage as a result of large wave forces.
