IEEE Transactions on Sustainable Energy, 2018 Wind farm cable length has a direct impact on the project cost, reliability, and electrical losses. The optimum cable layout results in a lower unit cost of generating electricity offshore. This paper explores three cabling structures: the string structure, ring structure, and multiloop structure on a three-dimensional seabed The newly proposed ...

Development of a stochastic computational fluid dynamics approach for offshore wind farms [PDF]
, 2018 In this paper, a method for stochastic analysis of an offshore wind farm using computational fluid dynamics (CFD) is proposed. An existing offshore wind farm is modelled using a steady-state CFD solver at several deterministic input ranges and an ...

Study on Overvoltage of Wind Farm Under AC Fault at Sending End of HVDC Transmission System
Zhongguo dianli, 2023 When the short circuit ratio of receiving end AC system is small, the fault disturbance of sending end AC system may cause commutation failure of the inverter and overvoltage at the LCC-HVDC sending end AC bus.

Two-scale momentum theory for very large wind farms [PDF]
, 2016 A new theoretical approach is proposed to predict a practical upper limit to the efficiency of a very large wind farm. The new theory suggests that the efficiency of ideal turbines in an ideal very large wind farm depends primarily on a non-dimensional ...

An Aero-acoustic Noise Distribution Prediction Methodology for Offshore Wind Farms
Energies, 2018 Recently attention has been paid to wind farm noise due to its negative health impact, not only on human beings, but also to marine and terrestrial organisms. The current work proposes a numerical methodology to generate a numerical noise map for a given

Optimization of Wind Farm Self-Discipline Interval and Energy Storage System Configuration
IEEE Access, 2020 The uncertain and stochastic output of the wind farm results in a lot of problems when it is connected to the power grid. In order to improve the wind power's friendship to the grid, the wind farm should has a certain self-discipline level. In this paper,

Generalized coupled wake boundary layer model: applications and comparisons with field and LES data for two wind-farms [PDF]
, 2016 We describe a generalization of the Coupled Wake Boundary Layer (CWBL) model for wind-farms that can be used to evaluate the performance of wind-farms under arbitrary wind inflow directions whereas the original CWBL model (Stevens et al., J.

Comparison of wind farm control strategies under realistic offshore wind conditions: turbine quantities of interest [PDF]
Wind Energy ScienceWind farm flow control is a strategy to increase the efficiency and therefore lower the levelized cost of energy of a wind farm. This is done using turbine settings such as the yaw angle, blade pitch angles, or generator torque to manipulate the flow ...
