All physical principles of current wind machines are applied to Vortex as well, it is just a different and innovative way of harness energy from wind. ...
The familiar umbrella has been redesigned for power harvesting from renewable energy sources resulting in the Eco-Brella . Several engineering technologies are utilised: aerodynamics for fin design, mechatronics for power management, materials for thermoelectric and solar film, CAD for the layout, and heat transfer for human comfort. The result is a sustainable design capable ...
In its Annual Energy Outlook 2014, the U.S. Energy Information Administration estimates that 11 percent of the world’s total energy comes from renewable sources, including hydropower, biomass, biofuels and wind, geothermal and solar power. ...
Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...
In the previous study, the energy generation of two WECS deployed at Darling site were estimated using the statistical–based technique. ...
The impact of the wind generation on the power systems is no longer negligible if high penetration levels are going to be achieved. ...
Grid nodes voltages are not allowed to deviate excessively from nominal value. Appropriate measures should be taken to prevent such a deviation. The voltage difference between two nodes is strongly affected by reactive power flow. In contrast to frequency control, node voltage control must be achieved locally. This article investigates the use of a wind farm based on a doubly fed induction ...
This paper presents a voltage and frequency controller with neutral current compensation in a stand alone wind energy conversion system (WECS) employing an asynchronous generator. The proposed controller consists of a three leg insulated gate bipolar junction transistor (IGBT)–based voltage source converter and a battery energy ...
A huge number of wind generators are going to be connected with the existing network in the near future. Therefore, it is necessary to analyse various models of wind energy conversion systems (WECS) for the purpose of studying the impacts upon grid. ...
Wind energy conversion systems (WECS) have merits as environmentally friendly and renewable sources of energy. ...
This paper deals with a wind energy conversion system (WECS), based on a doubly fed induction generator (DFIG) and an electromechanical active power filter (APF). The objective is to respond simultaneously to electric energy requirement and power quality concerns. The proposed WECS is able not only to track the maximum power ...
One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than 71% of the earth's surface. The ocean energy technologies are separated in four main ...
The influence of wind distribution and wind turbines power curves on the estimated production is shown. Lastly, a comparison of small wind energy conversion systems (WECS) performances on various sites in Bulgaria and Corsica is performed and shows that, for a same rated wind turbine power, in a ...
The increasing power demand has led to the growth of new technologies that play an integral role in shaping the future energy market. Keeping in view of the environmental constraints, grid connected wind turbines are promising in increasing system reliability. ...
The renewable sources of energy are being connected to the local distribution system/local grid leading to embedded generation. ...
A wind energy conversion system (WECS) differs from a conventional power system. The power output of a conventional power plant can be controlled whereas; the power output of a WECS depends on the wind. This nature of WECS makes it difficult for analysis, design and management. ...
In this paper, optimal control of new wind energy conversion scheme where four-leg improved matrix converter (MC) is used for performance and stability enhancement, particularly for sites where most of the time low wind speeds prevails, has been explained. ...
