Conventional energy usage has various environmental effects that cause global warming. Renewable energy sources are thus more favorable because they have nearly zero emission. Wind energy, among the various renewable sources, finds increasing usage, concurrent with developing technology. In...

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...

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...

In this paper, the aerodynamic performance of the telescopic blade wind turbine concept has been analysed experimentally and computationally. A model-scale wind turbine with two-stage telescopic blades, having a chord ratio of 0.6, was studied in the wind tunnel for different blade extensions...

Energy security is sometimes used to advocate renewable energy systems. Renewable energy systems can improve some aspects of security, but they will not automatically lead to the removal of all types of security problems and new problems will most certainly arise. This paper analyses energy...

The remarkable expansion of global wind power capacity in many countries brings forward several key economic questions regarding the performance of impacted electricity markets. Wind forecast uncertainties and rules that penalize scheduling deviations often discourage wind energy producers from...

In this paper, we are studying an innovative solution to reduce fuel consumption and production cost for electricity production by Diesel generators. The solution is particularly suitable for remote areas where the cost of energy is very high not only because of inherent cost of technology but...

This paper is interested in the control of a wind energy conversion system (WECS) based on the doubly fed induction generator (DFIG) under grid fault conditions. A single line to ground fault and a double line to ground fault are tested during the hyper-synchronous operation of the DFIG wind...

A few recent works have suggested a morphing blade for wind turbine energy conversion. The concept is derived from fin and wing motions that better adapt to varying load conditions. Previous research has provided the fluid mechanic justification of this new concept. This paper establishes a...
