A method for forecasting ice buildup on wind turbines, comprising: recording current ice buildup data on at least one wind turbine, the current ice buildup data being determined by means of at least one vibration sensor or at least one acceleration sensor; using current and historical meteorological data for the location of at least one wind turbine; using current ice buildup data and historical ice buildup data; forecasting ice buildup based on a machine-learned model, where the forecasting of ice buildup includes uncertainty; characterized in that the method further comprises the steps: forecasting a probability of throttling and/or shutdown of the at least one wind turbine, wherein the probability of throttling and/or shutdown of the at least one wind turbine is based on the forecast ice buildup for the at least one wind turbine, wherein, in the step of forecasting the probability of throttling and/or shutdown of the at least one wind turbine, the at least one wind turbine is throttled when the forecast ice buildup on the at least one wind turbine reaches a threshold value S D, the at least one wind turbine is switched off when the forecast ice buildup on the at least one wind turbine reaches a threshold value S A, the threshold value S A being greater than the threshold value S D, and further parameters are included in the forecast of the probability of throttling and/or shutdown of the at least one wind turbine, the further parameters including material specifications of the rotor blade. recording current ice buildup data on at least one wind turbine, the current ice buildup data being determined by means of at least one vibration sensor or at least one acceleration sensor; using current and historical meteorological data for the location of at least one wind turbine; using current ice buildup data and historical ice buildup data; forecasting ice buildup based on a machine-learned model, where the forecasting of ice buildup includes uncertainty; characterized in that the method further comprises the steps: forecasting a probability of throttling and/or shutdown of the at least one wind turbine, wherein the probability of throttling and/or shutdown of the at least one wind turbine is based on the forecast ice buildup for the at least one wind turbine, wherein, in the step of forecasting the probability of throttling and/or shutdown of the at least one wind turbine, the at least one wind turbine is throttled when the forecast ice buildup on the at least one wind turbine reaches a threshold value S D, the at least one wind turbine is switched off when the forecast ice buildup on the at least one wind turbine reaches a threshold value S A, the threshold value S A being greater than the threshold value S D, and further parameters are included in the forecast of the probability of throttling and/or shutdown of the at least one wind turbine, the further parameters including material specifications of the rotor blade. forecasting a probability of throttling and/or shutdown of the at least one wind turbine, wherein the probability of throttling and/or shutdown of the at least one wind turbine is based on the forecast ice buildup for the at least one wind turbine, wherein, in the step of forecasting the probability of throttling and/or shutdown of the at least one wind turbine, the at least one wind turbine is throttled when the forecast ice buildup on the at least one wind turbine reaches a threshold value S D, the at least one wind turbine is switched off when the forecast ice buildup on the at least one wind turbine reaches a threshold value S A, the threshold value S A being greater than the threshold value S D, and further parameters are included in the forecast of the probability of throttling and/or shutdown of the at least one wind turbine, the further parameters including material specifications of the rotor blade.
