Wind power generation is becoming increasingly common in the portfolio mix of many utilities around the world. Wind turbines are presently available up to 5MW. Smaller turbines may be installed for individual customers and connected to the grid at the distribution level, and larger units are typically combined in a wind “farms” connected to bulk power systems at the transmission level. Turbines ranging...
Numerous technical issues arise with the close spacing of multiple wind turbines in a wind farm, particularly one with a severely limited spatial footprint. One of the most important factors under consideration is the wake effect. Since the energy losses due to wakes can significantly decrease the energy production and lead to fluctuations in the output power of a wind farm it is desired to determine...
Wake flow effect is one of the critical factors affecting wind turbine arrangement, since it affects the scale and economic operation of wind farm as well as making full use of wind energy. This paper begins with analyzing wake flow factors, which is important for establishing wake flow model, and then discusses several models used presently. Finally, stressed the use of the turbulence model for wind...
With the increased use of wind energy for the power generation several TSO have increasing difficulties for congestion forecasting due to the unpredictable nature of the energy source. An actual method used to deal with days-ahead congestion planning is based on an order of disconnection of the generation of the type ldquolast generation installed, first generation limitedrdquo. This paper proposes...
As the size and number of wind power plants (WPP) increases, power system planners will need to study their impact on the power system in more detail. As the level of wind power penetration into the grid increases, the transmission system integration requirements will become more critical [1-2]. A very large WPP may contain hundreds of megawatt-size wind turbines. These turbines are interconnected...
With the penetration of wind energy is becoming higher and higher in power systems, itpsilas necessary to investigate the impact of wind generations on small signal stability. This paper discusses small signal stability of large scale variable speed wind turbines with doubly fed induction generator integration, as they has the ability to vary their operating speed in order to gain optimum power extraction...
