Against the background of steadily increasing wind power generation worldwide, wind turbine manufacturers are continuing to develop a range of configurations with different combinations of pitch control, rotor speeds, gearboxes, generators and converters. This paper categorizes the main designs,...

This paper presents a review of the current state of the art solutions to the problem of wind farm optimal design. The aim of this work is to present the problem by identifying the most relevant issues involved in the design of a wind farm, as well as to discuss the optimization techniques and...

Wind energy has become a large contender of traditional fossil fuel energy, particularly with the successful operation of multi-megawatt sized wind turbines. However, reasonable wind speed is not adequately sustainable everywhere to build an economical wind farm. In wind energy conversion...

This study aimed to assess the potential of offshore wind power generation at Younggwang in Korea which is candidate site of the offshore wind farm planned to be constructed till 2019. Toward this purpose, offshore meteorological tower called HEMOSU-1 was installed and has collected the wind and...

Wind turbine blade design depends on several factors, such as turbine profile used, blade number, power factor, and tip speed ratio. The key to designing a wind turbine is to assess the optimal tip speed ratio (TSR). This will directly affect the power generated and, in turn, the effectiveness...

Photogrammetry, which is a proven measurement technique based on determination of the 3D coordinates of the points on an object by using two or more images taken from different positions, is proposed to be a promising and cost efficient alternative for monitoring the dynamic behavior of wind...

Indonesia has considerable wind and solar energy potential, especially on onshore areas. However the wind and solar energy utilization is still low due to the high investment costs. This paper analyzes the potential use of wind turbine and PV (photovoltaic) for a PV/wind hybrid system in an...

Nowadays the use of renewable energy including wind energy has risen dramatically. Because of the increasing development of wind power production, improvement of the prediction of wind turbine output energy using classical or intelligent methods is necessary. To optimize the power produced in a...

The capacity factor is an essential indicator in evaluating a wind turbine's efficiency. In this paper, four kinds of power curve models—linear, quadratic, cubic, and general—are applied to estimate the capacity factor of a pitch-controlled wind turbine based on the Weibull probability...

This paper analyzes the performance of multi-MW wind turbines by means of a specific numerical model, with the aim of evaluating the application of an advanced hydrostatic transmission in a conventional state-of-the-art machine. The interest for such a solution is mainly related to the potential...
