Aly Mousaad Aly
Overview: The goal of this project is to enable the building of smart, resilient, and sustainable energy infrastructure, by advancing fundamental knowledge in the science of aerodynamics and control theory. The main objective is to test the following hypotheses: (i) semi-active control of structures can be carried out analytically, (ii) a proposed innovative control theory is applicable to flexible structures subjected to multi-hazard loads, and (iii) the proposed control approach is applicable to wind turbines in the field. A probabilistic approach to the semi-active control of multi-degree-of-freedom (MDOF) structures will

Therefore, the results of this study potentially can reduce the final cost of electricity production from wind.
Main Tasks: To accomplish the objective of the project, field experiments, as the best references for future development, are required in conjugation with analytical and numerical investigations. In Figure 1 a general perspective of the research is illustrated. The whole project will be executed in three main tasks which are described as follows:
Task 1. Data Collection and Analysis: The first task to accomplish the goals of the project is to collect high quality data that consist of the wind velocity field and profile, wind turbine’s dynamic responses and the power production. Due to the wind velocity fluctuation or high intensity turbulence which is an important characteristic of the wind in atmospheric boundary layer, the rotor and the tower of a wind turbine normally experience extensive fluctuating dynamic loads. Because of the randomness nature of these fluctuations, limitations in numerical simulations and scale related issues in laboratory tests, field wind data collection is super beneficial for scientific evolution of wind turbines. During the last years, a high quality remote system is introduced and implemented by wind energy developers to capture the wind data in-front of the wind
With no doubt in mind the wind power plants are safer than most power providing resources. Providing clean energy for the human race and having a positive influence on climate change, the wind power industry is on a rise. With help from the government and with companies becoming more prominent on efficient energy, we could see an even bigger demand for wind power. Environmentally, the wind farms are one of the safest because of the low carbon and emission levels. Continuing are efforts to a safer future, the world is looking into wind farms more and more to help generate enough energy for the human
One of the great parts about wind energy is that it has a large amount of positives to the environment and hardly any negative effects. Because wind energy uses the wind for the energy there is no emissions generated from the energy produced. It is estimated that the use of one million kWh of wind power can save around 600 tons of carbon dioxide emissions (Saidur, Rahim, Islam, & Solangi, 2011). Therefore, it is easy to see that the widespread use of wind power can help mitigate climate change. This is critical to help stop climate change and the United States is uniquely positioned to be the leader in curbing climate. When the United States starts heavily investing in alternative energy sources other countries will likely follow suit, which will be key to reducing global emissions.
In over 20 years of electricity generation with more than 100,000 machines installed worldwide, no member of the public has ever been injured during the operation of a wind turbine. These stats recorded show that the wind turbines are very safe and have a good reputation.
Wind turbines are becoming more and more popular across the flatlands of America. Along the same lines as solar power plants in California, there are many issues with wind turbines. Wind turbines are massive towers with a swinging blade that can create wind of up to 100 miles per hour over an acre of air. Turbines require a massive amount of tree removal, roads to be resurfaced and sometimes rebuilt (to access the intended installation area), lots of heavy machinery, digging into bedrock so as to create a good foundation for the tower. It takes 15 to 20 turbines to make it efficient, so it makes all
Wind Turbines and wind energy have been proven to be helpful, in the fact that it is a renewable resource. There is always a downside to something good, even with something that seems perfect. There are a few downsides to wind turbines themselves, some being environmental problems. I expected
The consumer can find a lot of savings in costs to be achieved from using wind power. The cost of wind power has

Along with these benefits come many practical difficulties associated with offshore wind projects. Offshore projects are expensive, particularly when paralleled with those projects which are land-based. The surface of ocean is a harsh place to maintain and build these structures. Due to this reason, high winds that carry larger amounts of energy threaten the steadiness of wind turbines which causes installation to become much more rigorous and costly. Furthermore, it also fetches the need for monitoring which is an expensive and automated system for maintenance. Underwater topography presently describes the viability of installation as most current models use foundations rooted directly into sea beds that are shallow.
We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

Wind power can be produced by air flow turning wind turbines or sails, often used to create mechanical or electrical power. As one of the clean and recycle energy, more and more countries pay attention to wind power. According to the recent EU analysis for the new constructions, the cost of the wind power has fallen to a fifth of that cost in the 20th century during the last 10 years, due to use the new method of math modeling and the new technology of the electrical component. With the development of the analysis in wind power, engineering mathematics takes an important part in using the wind to produce electrical
Abstract- Wind energy is an affordable, efficient and abundant source of electricity. The wind energy farms are differed as of on-shore and off-shore. Though wind energy seems to be an solution for growing world energy needs its there are hurdles in its generation. This article will discuss about a case study of an off-shore based wind energy power plant and discuss about basic analysis types and their corresponding application in WT’s system safety aiming to let more experts deeply understand the current research status. We shall also discuss about recent innovation in Wind turbine technology and our own idea of using the latest innovation in different area.
Following the recent developments in renewable energy sources, wind turbines have been one of the primary devices focussed on. Basically, wind turbines are devices that convert the kinetic energy from the wind into electrical power for human usage. “Wind farms” are created in very windy places to harness this energy.
1. INTRODUCTION: During last few years, the implementation of renewable project across the world has taken great efforts. In that the wind energy conversations projects are very problematic due to increase of wind power penetration into grid, the power
