Analyzing Effects of Seasonal Variations in Wind Generation and Load on Voltage Profiles [PDF]

open access: yesarXiv, 2017
This paper presents a methodology for building daily profiles of wind generation and load for different seasons to assess their impacts on voltage violations. The measurement-based wind models showed very high accuracy when validated against several years of actual wind power data.

Analytical investigation of wind loads on heliostats

open access: yesRevue des Énergies Renouvelables, 2016
Applications of Heliostats for solar power tower plants increased in the recent years. Most of the solar power tower plants installed are on flat terrain and they may be subjected to wind loads.

Advantages of modeling ABL properties to determine wind loads on structures

open access: yesMATEC Web of Conferences, 2018
In present paper we introduce the main advantages of modeling atmospheric boundary layer (ABL) properties for determination of mean and peak wind loads on structures. Experimental tests were carried out using wind tunnel with uniform velocity profile and

A surrogate model for estimating extreme tower loads on wind turbines based on random forest proximities [PDF]

open access: yesarXiv, 2019
In the present paper we present a surrogate model, which can be used to estimate extreme tower loads on a wind turbine from a number of signals and a suitable simulation tool. Due to the requirements of the International Electrotechnical Commission (IEC) Standard 61400-1, assessing extreme tower loads on wind turbines constitutes a key component of the

Monitoring Based Fatigue Damage Prognosis of Wind Turbine Composite Blades under Uncertain Wind Loads [PDF]

open access: yesarXiv
Lifecycle assessment of wind turbines is essential to improve their design and to optimum maintenance plans for preventing failures during the design life. A critical element of wind turbines is the composite blade due to uncertain cyclic wind loads with relatively high frequency and amplitude in offshore environments. It is critical to detect the wind

Influence of local scour on the dynamic responses of OWTs under wind-wave loads

open access: yesFrontiers in Marine Science
Offshore wind turbines (OWTs) often operate in complex marine environments, where they are not only subjected to wind and wave loads, but also adversely affected by scour.
