To indicate the best airfoil profile for different sections of a blade, five airfoils; included S8xx, FFA and AH series was studied. Among the most popular wind power blades for this application were selected, in order to find the optimum performance. Nowadays, modern wind turbines are using blades with multi airfoils at different sections. SST-K-ω model with different wind speed at large scale...

Despite many advances in the area of wind effects on structures in recent decades, research has been traditionally conducted within limited resources scattered geographically. With the trend toward increasingly complex designs of civil infrastructure combined with the escalating potential for losses by extreme wind events, a new culture of research needs to be established based on innovative an...

This paper presents methods for using parallel computer systems to optimize performance of previously published methods for snow modelling, to achieve real-time performance. These methods have not been created with real-time use in mind, and therefore require much computational resources. The method includes a model and parallelization scheme for snowflake motion in the air, simulation of a win...

the shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. in reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a s-shape profile. the pr...

Keywords: Oscillatory stability margin Monte Carlo simulation Nataf transformation Statistical indices Wind power a b s t r a c t With the increase in penetration of wind power which is essentially intermittent and random, the dynamic performance of the power system will change significantly, and so will the characteristics of the oscillations and their stability margins. This paper provides an...

The wind environment around a building influences human lives and the design of it. Simulation by CFD software is a main method used to study wind environment. But the reliability of the simulation result needs to be proved by comparing to the measured wind environment data. Experiment and simulation on wind environment were carried out in this reasearch. What’s more, different simulation metho...

Hybrid PV/Wind power system can be used to generate electricity consumed in household. This paper presents the design of a stand-alone Hybrid PV/Wind energy system for a household in University of Nigeria, Nsukka (UNN) in Eastern Nigeria with a daily load of 5.2kwh/d. Solar and wind resources for the design of the system were obtained from the NASA Surface Meteorology and solar energy website a...

Wind power generation is variable and uncertain. In the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. In this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via Monte Carlo simulation ...
