Some details on how this can be approached is outlined in the scientific paper here (free preprint available here) which also details why high-lift airfoils are optimal for flying wind turbines/power generating kites. From 2D to 3D, and What About the Rotors? ...
As the small plane banked for our approach, a row of wind turbines appeared atop a ridge. Installed in 2009 they are among the numerous renewable power installations that have popped up across rural Alaska in the past decade. ...

Basically, the wind turbine power curves change with wind speed as well as several other environmental conditions, e.g. air density, wind shear, turbulence, inflow angle. Accounting for the variation in each turbine’s gross power generation on a minute by minute (or hour by ...
At some point, the voltage discharges in the form of a lightning bolt and the heavy ice crystals falling to the earth as hail or rain. Solar panels, wind turbines and power lines: helplessly exposed? For power lines, wind turbines and photovoltaic plants, lightning strikes have serious ...
The streamlined design contains no contacting moving parts, making it virtually noiseless and less prone to vibration. Vortex Bladeless, the turbine’s Spanish developers, hopes these advantages could finally help usher in a viable consumer wind power market. ...
2015’s official Wind Energy Forecast for the South African market was released today detailing the key market trends in 2015 for wind energy in in the country. ...
This paper presents the development and qualitative validation of a doubly-fed induction generator (DFIG) wind turbine model that is represented in terms of behaviour equations of each of the subsystems, mainly the turbine rotor, the drive train, the induction generator, the power converters and associated control systems and a ...
We have focused on the leading wind turbine manufacturers [i.e., manufacturers of entire wind turbine system integrators (EWSIs)], as well as manufacturers of the turbines' sub–ecosystems (i.e., four key component provider manufacturers: blade, gearbox, generator and control system). A network analysis method was ...
It is important to find a quick and sustainable solution. Siemens, the market leader in power technology, concentrates on renewable energy, solar energy and wind power especially. ...
The increasing energy demands, insufficient availability of power generation and increasing global environmental problems, need alternate/green power sources. Among the different green power technologies such as wind power, photovoltaic, gas turbine and fuel cell, the fuel cell-based distributed ...
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 ...
Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. ...
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. ...
Today's power electronics can confer high-performance adjustment capabilities on any technological object, including the frequency-power and voltage tuning of modern, synchronous-type wind turbines. ...
In addition, expect to see a lot more solar panels and small wind turbines powering stores and offices very soon as a result of significant tax credits and loan guarantees. The stimulus funds should lead to 121 MW more of solar units on commercial buildings by 2011, a 15% jump, and 120 MW in distributed wind ...
Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. ...
Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. ...
Due to wind speed variations, the output power of wind turbines fluctuates. These power fluctuations make the wind power undispatchable. Furthermore, they can cause frequency deviations and power outage particularly when wind ...
In this paper Optimal Power Flow (OPF) problem is solved for a power system, which includes wind power as an additional generation input under variable load conditions. The fixed-speed Wind Turbine Generator (WTG) option is considered in this study: simulations have been performed for various ...
These features are mostly based on the large flexibility of an electricity system with decentralised energy production and might help to master future challenges in power markets, e.g. the increasing degree of stochasticity in the power system through the introduction of wind power turbines on a large scale. This ...
