Aeroelastic load simulations on a Siemens 2.3MW wind turbine have been validated using load measurements from the turbine and wind inflow measurements from a Nacelle based Lidar. A detailed survey of industrial usage of Nacelle mounted Lidars has also been conducted to extrapolate the findings from the present study to a broader framework.. Based on this information we assess the current techno...

This paper investigates the use of disturbance models in the design of wind turbine individual pitch controllers. Previous work has used individual pitch control and disturbance models with the Multiblade Coordinate Transformation to design controllers that reduce the blade loads at the frequencies associated with the rotor speed. This paper takes a similar approach of using a disturbance model...

One of the critical design driving load cases for modern large onshore/offshore wind turbines is power production in extreme turbulence. According to the IEC 61400-1 edition 3 design standard, the normal production extreme loads are extrapolated and compared to the extreme loads obtained under extreme turbulence input. This study shows that using a probabilistic approach and the first order rel...

In current design practice, spatiotemporally varying wind loads on buildings are modeled as equivalent static wind loads. This loading description serves as pivotal information for estimating response under the combined action of wind and other loads. This paper presents a framework for evaluating the equivalent static wind load for any given peak response of buildings with uncoupled responses ...

Wind energy offers a significant advantage such as no fuel costs and no emissions from generation. However, wind energy sources are variable and non-dispatchable. The utility grid is able to accommodate the variability of wind in smaller proportion along with the daily load. However, at high penetration levels, the variability can severely impact the utility reserve requirements and the cost as...

Abstract—Nowadays, the use of renewable energy sources has been increasingly great because of the cost increase and public demand for clean energy sources. One of the fastest growing sources is wind energy. In this paper, Wind Diesel Hybrid System (WDHS) comprising a Diesel Generator (DG), a Wind Turbine Generator (WTG), the Consumer Load, a Battery-based Energy Storage System (BESS), and a Dum...

This paper proposes a new methodology for evaluating the probabilistic reliability based grid expansion planning of composite power system including the Wind Turbine Generators. The proposed model includes capacity limitations and uncertainties of the generators and transmission lines. It proposes to handle the uncertainties of system elements (generators, lines, transformers and wind resources...

This paper investigates the performance of the semiactive control system based on magnetorheological fluid (MR) dampers for suppressing excessive vibration of stay cable installed in cable-stayed bridges under wind load. The cable model is extracted from a 156.3 m long stay cable with high tension. The external wind load is generated from the widely used wind load spectrum such as the Kaimal sp...

Extreme wind loads used in design (e.g., the 50-yr wind load) and include nominal design wind loads ultimate wind loads. This paper briefly reviews the relationship between extreme wind loads and extreme wind speeds, assessments of epochal versus ‘peak-overthreshold’ approaches for estimating extreme non-tornadic winds in areas not subjected to tropical storms, and methods for estimating extrem...

Increasing load of air pollution in urban environment emphasises the need for detailed evaluation of wind characteristics that significantly affect the air quality of urban areas, especially, in large agglomerations. This paper includes analysis of urban wind cli-matology and estimation of wind profiles based on measurements of the new urban 5 climate station located at the E ¨ otvös University...
