WIND-GENERATED LONGSHORE CURRENTS

open access: yesCoastal Engineering Proceedings, 1978
This paper evaluates, through the use of a stepwise multiple regression procedure, whether parameters descriptive of the surf-zone wave field adequately explain the variability in longshore current velocities, or if the inclusion of additional physical environmental parameters could significantly improve the ability to predict such currents.

No-load cutting-in control of the doubly fed induction generator based on grey prediction PI control

open access: yesEnergy Reports, 2021
The traditional method of stator flux oriented PI control of the doubly fed induction wind generator (DFIG) no-load cutting-in is easy to implement under ideal conditions, but in the actual project with high frequency of wind speed change, the feedback ...

Combining hydro-generation and wind energy biddings and operation on electricity spot markets [PDF]

open access: yes, 2006
Wind generation is growing rapidly in all the world, especially in Europe. The power produced by this kind of generation is difficult to predict and the predictions are not very accurate. In most systems these imbalances are costly.

Contracting for Wind Generation [PDF]

open access: yesEconomics of Energy & Environmental Policy, 2012
The UK Government proposes offering long-term Feed-in-Tariffs (FiTs) to low-carbon generation to reduce risk and encourage new entrants. Their preference is for a Contract-for-Difference (CfD) or a premium FiT (pFiT) for all generation regardless of type. I argue that neither is suitable for on-shore wind, where a fixed FiT appears less risky.

Criterion for Generation of Winds from Magnetized Accretion Disks [PDF]

open access: yes, 2001
An analytic model is proposed for non-radiating accretion flows accompanied by up or down winds in a global magnetic field. Physical quantities in this model solution are written in variable-separated forms, and their radial parts are simple power law ...

Forecasting wind speed data by using a combination of ARIMA model with single exponential smoothing [PDF]

open access: yes, 2021
Wind serves as natural resources as the solution to minimize global warming and has been commonly used to produce electricity. Because of their uncontrollable wind characteristics, wind speed forecasting is considered one of the best challenges in ...

An assessment of principles of access for wind generation curtailment in active network management schemes [PDF]

open access: yes, 2013
The growth of wind generation embedded in distribution networks is leading to the development and implementation of Active Network Management (ANM) strategies.

Comparison of Blade Aeroelastic Responses between Upwind and Downwind of 10 MW Wind Turbines under the Shear Wind Condition

open access: yesEnergies, 2023
This paper examines the potential for reducing the cost of energy for super-scale wind turbines through the use of a downwind configuration. Using nonlinear aeroelastic modeling, the responses of 10 MW upwind and downwind wind turbine blades are ...
