A High-Performance Control Model Of Grid-Connected Wind

As the global supply of fossil fuels becomes steadily lower, need is growing for new energy sources that are beneficial to the environment and cost-effective. Wind power is one solution to this need. Wind turbines require significant investment, but are cost-efficient in the long term. If construction of turbines is sufficiently increased, the wind may be able to in the future provide a very major portion of global energy.

2) Case II: Power Converters supplying power in a standalone mode or feeding it back to the utility mains Fig. shows many diagram of power block converters for a standalone AC system or feeding produce powers back to the utility mains. If all generators are directly connected to the loads, the systems operate as a standalone AC system. Meanwhile, if these are connected in parallel to the mains, these provide the utility grids with an electric power.

Wind energy or wind power is extracted from air flow using wind turbines or sails to produce mechanical or electrical energy. Windmills are used for their mechanical power, wind pumps for water pumping, and sails to propel ships.

In our world today, energy is needed to work our technologies and help us complete daily task. With a growing population, the demand for energy is very high. Harnessing the energy could sometimes be difficult and dangerous to ourselves and the environment. Fossil fuels and nuclear power are the most used types of energy in the United States. The problem with this is that the energy is limited, and harmful to the environment. Wind energy is an alternative renewable energy source that counters this problem, and is rapidly emerging in our world.

Wind Power is the use of our natural wind that converts it into mechanical energy which eventually becomes electricity. You may not realize this, but we used wind power that dated centuries ago. It pumped water, ground grain, and plenty of other things. (Resources, awea.org)

Wind power captures natural wind and converts it into mechanical energy and then electricity. Wind energy is the fastest growing energy source in the world; aiming to produce 20% of its electricity by wind power by 2030. We started using wind power centuries ago with windmills, they pumped water, grounded grain and so much more. Wind turbines today are a much more evolved version of a windmill. They range in size at 80 feet tall and can power a single home. And a utility scale turbine can power hundreds of homes. It is a renewable, clean source of energy that doesn’t generate any greenhouse gases. It can possibly improve (or not) our lives at home and work.

In the society we live in today, many people have the misconception that there is a never-ending supply of energy available for our wasteful use. However, people must realize that the fossil fuels that we have come to depend on for our energy are quickly being depleted. There are several renewable energy resources, most of which come from the sun, that are available for our use. One of these abundant energy resources is the wind. By taking advantage of the wind, and harnessing its power to supply useful energy, people can ensure that they will have energy for as long as the sun continues to heat the earth.

For years the United States has been searching for an efficient form of clean energy. Wind energy has the potential to become the base of sustainable energy for America’s future. Although there are a few disadvantages to wind energy, the protection it offers along with the economical and environmental advantages provide many reasons to use more wind energy and less coal and fossil fuels in America.

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 is harnessed using wind turbines, which transforms the energy into electrical power. Wind turbines are typically designed either on a horizontal-axis or a vertical-axis. According to the U.S. Environmental Protection Agency, “horizontal-axis wind turbines have either two or three long blades that collect the energy in the wind and convert it to electricity.” Additionally, “the blades spin when the wind blows over them and the energy of motion contained in the

The renewable energy from wind energy has become a popular method of producing energy. When the world realized fossil fuel emission are harmful to our atmosphere, many countries started to look toward renewable energy sources. In recent years the U.S. has given tax incentives and tax breaks for using a renewable energy sources. The U.S. has become the leaders in using wind energy for a renewable resources. Even though wind power energy is growing in popularity among government officials and the general public, however wind energy has some problems and challenges in providing energy to the world, both in the short and the long term. Wind energy used alone is not the approach

Renewable forms of energy are becoming more and more necessary for a sustainable future. Wind energy is a form of energy that is becoming more and more popular, and it offers a way for people to harness energy from something natural to create electricity. Wind energy in addition to other sustainable forms of creating energy are going to start taking the place of fossil fuels as people realize the true benefits of using them.

As the harmful side effects of fossil fuel burning become evermore recognized, the use of clean, renewable technology becomes essential to our health, economy and environment. Petroleum and coal emit harmful pollutants into the atmosphere, contributing to global warming, acid rain and a host of other aliments. Equally concerning is the dependence of the economy on a finite resource such as oil. With world energy consumption rapidly rising, demand is increasing for renewable energy sources that have no significant health impact or environmental degradation. Of all these so called “green” energy sources, wind power has been the most widely used. Wind power is based on the same principals as windmills used for centuries; wind turbines harness

Fossil fuels are having great impacts toward nature such as global warming and greenhouse effect. Plus, the depletion of it contributes to the rising price of petroleum. Therefore, wind power rise as it is a source of clean, non-polluting renewable energy (Nash, 2008). This type of energy generation provides us with loads of benefits environmentally and economically.

Wind power is a clean and renewable energy that, while at times unreliable, has very low upkeep cost and is growing at a rapid rate. While there is currently enough wind power to provide many times our current energy need, it is unfeasible in reality. Wind power utilizes the kinetic energy of air and uses it to power a generator to produce electricity. Even though dependence on wind power is impossible, it still can provide a strong, clean, quantity of power to supplement current energy production.
