摘要： The present disclosure relates to controlling an operation of a wind turbine. A first plurality of extreme load measures indicative of extreme loads experienced by at least part of the wind turbine during the first period of time are determined and a load probability characteristic is then determined based on a statistical analysis of the distribution of the first plurality of extreme load measures. A control strategy for controlling the operation of the wind turbine is then modified based at least in part on a comparison of the load probability characteristic and a design load limit and the wind turbine is then subsequently controlled in accordance with the modified control strategy for a second period of time.

摘要： Systems and methods are provided for controlling a power generating asset having an energy storage device. Accordingly, a controller of the power generating asset initiates a state-change event for the energy storage device. The controller determines an actual equivalent series resistance (ESR) function for the energy storage device based on a change in a first and a second electrical condition at each of a plurality of sampling intervals of the state-change event. The controller determines a state-of-health rating for the energy storage device based on the actual ESR function and implements a control action based on the state-of-health rating.

摘要： A method for operating a first wind power installation comprising a rotor having a rotor blade that is adjustable with a pitch angle, which generates an electrical power and in the wake of which a second wind power installation is located in at least one wake wind direction, comprising the step of: operating the first wind power installation in a substantially wake-free normal mode with a first pitch characteristic, and operating the first wind power installation in a wake-loaded wake mode with a second pitch characteristic, wherein the first pitch characteristic represents a first profile of the pitch angle and the second pitch characteristic represents a second profile of the pitch angle as a function of the electrical power, wherein the pitch angle of the second pitch characteristic is greater than the pitch angle of the first pitch characteristic for at least one range of the electrical power. The method seeks to maximise the annual energy production of the second wind power installation while complying with constraints, such as compliance with maximum thrust coefficients or wake-influenced turbulence intensities.
