The expanded integration of wind energy imposes technical challenges to maintain system reliability. In order to tackle these challenges, comprehensive reliability models for wind turbines and related factors are essential. Proposed algorithm classifies Wind Turbine Generator (WTG) components based on their impact on WTG output. There upon, the WTG has a composite three-state reliability model which...
According to the growth of power generated by wind farms and the increased number of non-linear loads, providing a high quality electrical power, should be considered. This paper is addressed the issue of application and analysis of a Dynamic Voltage Restorer (DVR) to enhance the quality of power flows in a stand-alone microgrid, including wind energy conversion systems and the sensitive loads. The...
This paper deals with optimal operation planning to maximize the energy yield from a wind farm. In order to accomplish this, it is necessary to consider the electrical parameters, such as compliance with the Grid Code, for a sufficient integration of the wind farm into the power grid. Aerodynamic issues like optimal wind turbine positioning, in order to decrease the wake-effect and maximize the energy...
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...
To effectively harness the power of wind electricity generation, significant infrastructure challenges exist. First, the individual wind turbines must be sited and constructed as part of a wind farm. Second, the wind farm must be connected to the electricity grid infrastructure and the power generated managed accordingly. Due to its stochastic nature, wind energy cannot be controlled; it must be managed...
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...
