STUDY ON MODELLING STANDARDIZATION OF DOUBLE-FED WIND TURBINE AND ITS APPLICATION
Based on the standardized modelling of the International Modelling Team, study on double-fed induction generator (DFIG) wind turbine is processed in this paper, aiming at capability of universally and reasonably reflecting key performance related to large scale system analysis. The standardized model proposed is of high degree of structural modularity, easy functional extension and universalizatio...

ANALYTICAL MODELING OF WIND FARMS: A NEW APPROACH FOR POWER PREDICTION
Wind farm power production is known to be strongly affected by turbine wake effects. The purpose of this study is to develop and test a new analytical model for the prediction of wind turbine wakes and the associated power losses in wind farms. The new model is an extension of the one recently proposed by Bastankhah and Porté-Agel for the wake of stand-alone wind turbines. It satisfies the cons...

A METHODOLOGY FOR THE RECONSTRUCTION OF 2D HORIZONTAL WIND FIELDS OF WIND TURBINE WAKES BASED ON DUAL-DOPPLER LIDAR MEASUREMENTS
Dual-Doppler lidar is a powerful remote sensing technique that can accurately measure horizontal wind speeds and enable the reconstruction of two-dimensional wind fields based on measurements from two separate lidars. Previous research has provided a framework of dual-Doppler algorithms for processing both radar and lidar measurements, but their application to wake measurements has not been addres...

HIGH-RESOLUTION WAVE ENERGY ASSESSMENT IN SHALLOW WATER ACCOUNTING FOR TIDES
The wave energy in a shallow water location is evaluated considering the influence of the local tide and wind on the wave propagation. The target is the coastal area just north of the Portuguese city of Peniche, where a wave energy converter operates on the sea bottom. A wave modelling system based on SWAN has been implemented and focused on this coastal environment in a multilevel computational s...

VARIABILITY OF THE WIND TURBINE POWER CURVE
Wind turbine power curves are calibrated by turbine manufacturers under requirements stipulated by the International Electrotechnical Commission to provide a functional mapping between the mean wind speed v and the mean turbine power output P. Wind plant operators employ these power curves to estimate or forecast wind power generation under given wind conditions. However, it is general knowledge t...

ROBUST CONTROL OF WIND TURBINES BY USING SINGULAR PERTURBATION METHOD AND LINEAR PARAMETER VARYING MODEL
The maximum power point tracking problem of variable-speed wind turbine systems is studied in this paper. The wind conversion systems contain both mechanical part and electromagnetic part, which means the systems have time scale property. The wind turbine systems are modeled using singular perturbation methodology. A linear parameter varying (LPV) model is developed to approximate the nonlinear si...
