KiteGen: A revolution in wind energy generation
Energy, 2009Abstract Control of tethered airfoils is investigated, in order to devise a new class of wind generators to overcome the main limitations of the present wind technology, based on wind mills. A model from the literature is used to simulate the dynamic of a kite whose lines are suitably pulled by a control unit.

Managing Household Wind-Energy Generation
IEEE Intelligent Systems, 2008The use of intelligent-agent technology to aggregate wind-energy generation installed at several households and battery storage installed in similarly large number of households is described. This situation creates a virtual generator that can be dispatched on the electricity grid in a similar manner to to centralized generation.

Evaluation of wind-generator potentiality
Solar Energy, 1995Abstract The paper presents a method to analyse wind data for wind-turbine siting. Two parameters are defined by means of which the siting can be optimised, the site effectiveness (ratio output/available energy) and the cut-in speed. It is shown that the site effectiveness achieves a maximum for a value of the cut-in speed which depends on the rated ...

Series compensated open-winding PM generator wind generation system
2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012This paper presents a new wind power generation system utilizing an open-winding permanent magnet synchronous generator (PMSG). A diode rectifier is used for the major portion of power conversion process. In addition, the proposed system controls the generated power by using an auxiliary voltage source inverter located at the neutral of the generator ...

Journal of the Waterways and Harbors Division, 1966
The processes of wind-wave generation are examined in light of recent theoretical work by several applied mathematicians. Measurements of air pressure fluctuations over wind waves in laboratory tanks are presented, and the existence of a phase shift between the air pressure fluctuations and the water surface fluctuations (waves) is demonstrated through

Wind is the directional motion of air particles. The general circulation is a representation of climatic state of wind, which is a linear and delayed response of periodic solar radiation forcing. The timescale of general circulation is from diurnal cycle to seasonal cycle, while its spatial scale ranges from a small peninsula to continent and basin.
