Active control of wind turbines through varying blade tip sweep
(2019)In this research work an introduction to the concept of an actively controlled horizontal axis wind turbine through varying blade tip sweep, is presented. The concept refers to variable tip swept rotor blades, that have ... -
A comparative study of numerical schemes and turbulence models for wind turbine aerodynamics modelling
(2004)This paper is a comparative study of combining turbulence models and interpolation schemes to calculate turbulent flow around a NACA0012 airfoil before and after separation. The calculations were carried out using the code ... -
A learning approach for strategic consumers in smart electricity markets
(2016)In this paper we consider the design and the implementation of a machine learning approach and its integration with a widely used energy simulation platform. We focus on auction based energy markets which require their ... -
Monitoring fatigue damage accumulation of wind turbine towers using limited number of output-only vibration measurements
(2020)Fatigue monitoring and remaining fatigue life estimation of structures using output- only vibration measurements has recently garnered increasing attention, producing advances in theoretical, numerical and experimental ... -
On the adequacy of existing foundation schemes for offshore wind turbines subjected to extreme loading
(2017)Dictated by the world's escalating energy demands, offshore infrastructure is moving beyond the immediate continental shelf into deeper waters. Although the monopile solution has proven its reliability for many years, its ... -
A parametric study of the aeroelastic behaviour of wind turbine blades in classical flutter
(2006)A parametric study of the aeroelastic behaviour of a wind turbine blade 'typical section' in classical flutter is presented, using a new numerical model. The aerodynamic loads are computed by solving the RANS equations ... -
Pattern identification for wind power forecasting via complex network and recurrence plot time series analysis
(2019)Renewable energy sources, where wind energy is an important part, are increasingly participating in developing economies and environmental benefits. Wind power is strongly dependent on wind velocity and thus identifying ... -
Performance Assessment of a Steel Wind Turbine Tower Subjected to Repeated Earthquakes
(2022)As the wind market grows rapidly and wind power plants are installed in high seismicity areas, there is the increased need for researchers and practitioners to assess the dynamic performance of Wind Turbine (WT) structures ... -
Renewable energy sources generation forecasting in aggregated energy system level
(2021)Renewable Energy Sources (RES) generation forecasting is an approach to handle the stochasticity of RES. This concept is very crucial to transform RES plants into dispatchable and integrated them for contemporary energy ... -
A streamline approach to multiaxial fatigue monitoring using virtual sensing
(2022)This paper presents a framework for fatigue monitoring on linear components of a structure subjected to unknown loads using a limited number of output-only vibration measurements. It exploits virtual sensing techniques to ... -
Transient stability analysis of power systems with the participation of wind parks
(2021)Rising fuel prices, as well as worries about the environmental effects of greenhouse gas emissions, have sparked fresh interest in the generation of electrical energy from renewable sources, including wind power. The aim ...
