[1] This paper identifies the location of an “ideal” offshore wind energy (OWE) grid on the U.S. East Coast that would (1) provide the highest overall and peak-time summer capacity factor, (2) use bottom-mounted turbine foundations (depth ≤50 m), (3) connect regional transmissions grids from New England to the Mid-Atlantic, and (4) have a smoothed power output, reduced hourly ramp rates and hou...

Abstract We present a framework for optimizing the control parameters of floating offshore wind turbines (FOWTs). The combines aeroelastic simulations with systems engineering model and software. In an example optimization framework, we minimize tower damage equivalent loading generator speed constraints. also study effect thrust-limiting quantify trade off between fatigue energy capture using ...

Lateral tower vibrations of offshore wind turbines are normally lightly damped, and large amplitude vibrations induced by wind and wave loads in this direction may significantly shorten the fatigue life of the tower. This paper proposes the modeling and control of lateral tower vibrations in offshore wind turbines using active generator torque. To implement the active control algorithm, both th...

Variability in extreme loads is greater in areas in which hurricanes or tropical cyclones are likely. Therefore, it is expected that design standards for offshore structures in such areas should prescribe different load amplification factors if a uniform structural reliability is to be achieved at all locations. In this paper we examine and evaluate the adaptation of methods within the American...

Hurricanes are causing increasing damage to many coastal regions worldwide1,2. O shore wind turbines can provide substantial clean electricity year-round, but can they alsomitigate hurricane damage while avoiding damage to themselves? This study uses an advanced climate–weather computer model that correctly treats the energy extraction of wind turbines3,4 to examine this question. It finds that...

The efficiency of a wind turbine highly depends on the value of tip speed ratio during its operation. The power coefficient of a wind turbine varies with tip speed ratio. For maximum power extraction, it is very important to hold the tip speed ratio at optimum value and operate the variable-speed wind turbine at its maximum power coefficient. In this paper, an intelligent learning based adaptiv...
