nowadays,it is important to consider environmental issues,as ecological problems and their severe effect intensify in iran,particularly in khuzestan province.the environmental effects of hydroelectric plants are highly regarded due to their significant impact on an extensive area.the lack of safe path for fish passing through the turbines is one of these damages. in order to deal with these cha...

Hydropower is the largest renewable energy source in the world. However, in the Columbia and Snake River basins, several species of Pacific salmon and steelhead have been listed for protection under the Endangered Species Act due to significant declines of fish population. Dam operators and design engineers are thus faced with the task of making hydroelectric facilities more fish friendly throu...

Although fossil fuel is the main energy supplier of the worldwide economy, due to its ad‐ verse effects on environment, the scientists look for alternative resources in power genera‐ tion. Electricity generation using renewable energy has been well recognized as environmentally friendly, socially beneficial, and economically competitive for many appli‐ cations. Wind turbines, photovoltaic syste...

The use of wind power for energy production, renewable energy is one of the oldest methods for tapping. Socio-economic development and use of renewable energy is an essential component of economic development. Tidal energy, wind energy, etc., such as abundant renewable energy sources and reduce dependence on fossil fuels can help. With increased concern for environment now days led to the resea...

Wind energy systems are being closely studied be c a u s e of its benefits as an environmentally friendly and renewable source of energy. Because of its unpredictable availability, power management concepts are essential to extract as much power as possible from the wind when it becomes available. The purpose of this thesis is to presents a new adaptive control algorithm for maximum power point...

Hydropower has now become the best source of electricity on earth. It is produced due to the energy provided by moving or falling water. History proves that the cost of this electricity remains constant over the year. Because of the many advantages, most of the countries now have hydropower as the source of major electricity producer. The most important advantage of hydropower is that t is gree...

An “across-the-fence” steam-methane reforming (SMR) hydrogen plant integrated with gas-turbine technology was started up within the past three years at the Premcor refinery in Port Arthur, Texas. This plant, owned and operated by Air Products and Chemicals, Inc., is one of only a handful of SMRs containing an integrated gas turbine. The facility design typifies a growing trend among refiners to...

The productivity of electricity increases with the necessity, which in turns pollutes the environment. There are certain methods to produce electricity in Eco-friendly manner. Wind turbine is one such application which is 100% pollution free, renewable and produces a lot of energy. In general wind turbines have two operating principles namely fixed speed and variable speed. In this paper we hav...
