Validation of the Standard Method for Assessing Flicker From Wind Turbines

Paper presents a newfangled empirical model to figure, flicker, instigated in the horizontal axis, upwind turbine, due to wind turbulence, in continuous operation. Postulations, boundary curbs and limitations of the model are also depicted. In the proposed model, wind turbulence, number of blades, blade length and tower height are echoed. The exquisiteness of the model is that, it is expedient to range of heights of structures on which the turbine is sited. Validation of model is carried out with comparative graphs revealed after vigorous experimentation on a turbine in a tunnel with various heights of models of buildings.Index Terms--flicker emission, wind turbulence, wind turbine.

Abstract. This work studies the influence of the signal processing method on the flicker measurement of grid connected wind turbine in continuous operation according to the procedure detailed in the IEC 61400-21 standard. Two different methods for solving the fictitious grid are analyzed: Zero Crossing Detection and Short Time Fourier Transform. The deviations in the flicker measurement results obtained by applying both methods to actual signals from a measurement campaign are discussed. And the results are compared taking into account the grid impedance angle and the wind condition.

“…Voltage fluctuations due to aerodynamic power fluctuation can produce the worst power quality complications such as flicker in distribution systems. Power quality and flicker incidents due to wind energy were examined and inspected in [21,22]. Wind turbine units also contribute towards fault currents [23], which is another problem for grid integration systems consisting of wind power.…”

Abstract:Wind energy is one of the most common types of renewable energy resource. Due to its sustainability and environmental benefits, it is an emerging source for electric power generation. Rapid and random changes of wind speed makes it an irregular and inconsistent power source when connected to the grid, causing different technical problems in protection, power quality and generation dispatch control. Due to these problems, effective intermittent smoothing approaches for wind power output are crucially needed to minimize such problems. This paper reviews various intermittent smoothing approaches used in smoothing the output power fluctuations caused by wind energy. Problems associated with the inclusion of wind energy resources to grid are also briefly reviewed. From this review, it has been found that battery energy storage system is the most suitable and effective smoothing approach, provided that an effective control strategy is available for optimal utilization of battery energy system. This paper further demonstrates different control strategies built for battery energy storage system to obtain the smooth output wind power.
