“…An inverse reliability approach was employed to estimate nominal design loads. For the 600kW wind turbine considered, the environmental and response probabilistic descriptions were obtained from a study by Ronold and Larsen (2000). Extreme flapwise bending loads were studied and, for this turbine, it was found that the difference between the nominal loads derived from 1-D and 2-D models was very small since the standard deviation of wind speed at the hub height had a very small effect on the extreme bending load compared with the mean wind speed.…”

“…The response variable there was treated as deterministic allowing the use of 2-D environmental contours based on Winterstein et al (1993). In the present study, our interest is in estimating design extreme flapwise bending loads for a 600kW three-bladed horizontal-axis wind turbine that was previously studied by Ronold and Larsen (2000), where results from field measurements were reported and probabilistic models for response (loads) conditional on inflow conditions were presented. The distinction between the present study and that by Fitzwater et al (2003) is that we propose alternative nominal load definitions (one of which includes response variability) and we employ field data instead of simulations in developing parametric models for the random response conditional on inflow.…”

“…Veers [17] noticed the random and uncertain parameters involved in the component design of wind turbines and first performed reliability analysis for a vertical axis wind turbine blade. Around the 2000s, Ronold et al [40,41] applied reliability methods to analyses of rotor blades of horizontal-axis wind turbines. Afterwards, more probabilistic models of wind turbine structural components were proposed, and advanced wind turbine simulation tools came to use in SRA.…”

“…Several different procedures have been suggested in studies by Madsen et al, 1 Larsen et al, 2 Ronold and Larsen, 3 Fitzwater and Winterstein, 4 Manuel et al, 5 Fitzwater et al, 6 Moriarty et al, 7,8 Peeringa, 9 and Cheng et al 10 Many of these studies focus on how to model the distribution of turbine loads conditional on inflow random variables using parametric approaches. Such conditional load distributions are next integrated with the joint probability distribution of all probable environmental or inflow conditions to finally yield by extrapolation the desired long-term load associated with a given reliability level or probability of failure.…”
