“…For a wind turbine with a fixed pitch angle of blades, the tip-speed ratio has an optimum value (λ opt ) for which the power coefficient is at a maximum (C p max ). It is specified that the optimal tip-speed ratio ranges from 6 to 8 and that the maximum power coefficient varies between 0.4 and 0.5 for large WTSs [18]. The analytic expression for the maximum value of power coefficient with the optimum tip-speed ratio is given as follows:…”

“…The amount of produced energy by a WTS changes according to the site, because different sites have different wind characteristics in terms of mean wind speed, frequency, and direction. Accordingly, there have been a number of studies on performing site-specific design optimization of WTSs in the literature [5,[10][11][12][13][14][15][16][17][18]. A basic model for COE was given in [5].…”

“…In that study, the blade element momentum theory given in [11] was used to compute the amount of energy production. In [12][13][14][15]18], site-specific methods for optimizing WTSs based on cost reduction, for which the objective function was per cost of energy, were proposed. Design optimization was performed to maximize produced energy at minimum cost and site wind characteristics were incorporated into the design process.…”

Abstract:Due to the complexity of wind turbine systems (WTSs) containing multiple components, design parameters of a WTS must match each other in order to produce electrical energy at a lower cost and a higher efficiency. In this study, a framework for site-specific design optimization of a horizontal-axis WTS is proposed. It is based on cost reduction and the objective function is the produced energy cost. The cost of energy model proposed by the National Renewable Energy Laboratory is utilized. In order to compute turbine output power that results in annual energy production, a new approach is proposed to model the power coefficient of rotor for fixed-speed WTSs. Design optimizations are performed by using a particle swarm optimization algorithm, which appears to be efficient for this type of problem.WTSs in northern Europe and the Mediterranean were studied. Results show that optimized WTSs for these sites have high profitability in terms of cost and amount of energy when compared with reference WTSs installed in these sites.Parametric analyses are also undertaken in order to evaluate the effect of wind characteristics on the produced energy cost for both types of WTSs and the effects of rotor tip-speed ratio and turbine-rated power on the design parameters and produced energy cost for fixed-speed WTSs. It is concluded that rotor tip-speed ratio has strong effects on design wind speed for fixed-speed WTSs and on the cost of kWh.

“…It is not surprising how great the interest in wind potential is because its usage has many advantages. Most cost-effective and reliable large wind energy conversion systems are becoming the main focus of wind energy technology development in order to make this type of energy competitive with the other, more traditional sources of electrical energy production from energents like coal, gas and nuclear generation (Li, Chen, 2009). …”

Renewable energy sources play an important role in the future not only for the European countries, but for many countries worldwide. Most cost-effective and reliable large wind energy conversion systems are becoming the main focus of wind energy research and technology development, all in order to make wind energy competitive with other more traditional sources of electrical energy like coal, gas and nuclear generation. Serbia, along with neighbouring countries, has a high potential for developing energy production from renewable energy sources. Wind energy in Serbia, despite its great potential, is only partly studied and insufficiently used. This study aims to provide summary of wind energy potentials in the region of Vojvodina, which is an important economic region in northern Serbia. Its existing electrical energy status is thoroughly investigated according to the recent developments of wind energy production on global, regional and local scale. The main purpose of this study is the implementation of energy efficiency concept with purpose of satisfying the needs of Serbian electricity market.

As a service to readers, Wind Energy regularly conducts literature surveys and publishes lists of relevant articles drawn from recent issues of a large number of periodicals including: Journal of Wind Engineering and Industrial Aerodynamics, International Journal of Energy Research, Renewable Energy, Energy Sources, Journal of Solar Energy Engineering, American Institute of Aeronautics and Astronautics Journal, Electric Power Components and Systems along with a number of periodicals published by the Institute of Electrical and Electronics Engineers, etc. The list is limited exclusively to journals not specifically devoted to wind energy and its applications. To assist the reader, the list is separated into broad categories. Although many papers fit several categories, each paper is listed only once under the category thought most appropriate. Please note that the inclusion in the list is not an endorsement of a paper's quality.
