“…During normal operation, voltage changes resulting from fluctuations of the DG output power may create flicker problems, a well-known fact for WTs [26][27][28][29]. According to IEC 61400-21, the expected flicker emissions of WTs can be assessed using the flicker coefficient, c(ψ k , v a ), dependent on the average annual wind speed, v a , at the WT installation site and the grid short circuit impedance angle, ψ k :…”

“…For already installed generator units, small series or unique drive systems these are no applicable solutions, so additional actuators have to be used to reduce vibration and noise. For instance the authors of [1] describe how combustion engines as used in combined heat and power stations can be a cause of flicker in island networks due to the pulsed variation of torque. [2] investigates generator damages caused by oscillations due to heavily varying loads in the supply of a fusion reactor.…”

Abstract. In this paper a device for wideband, multi frequency active vibration cancellation for rotating drive trains is presented. It can be installed subsequently into problematic drive trains (e.g. wind turbines, combined heat and power stations …) and can be individually fit to the constructive limits given by the existing system. A formula to calculate the mechanical properties of the actuator is derived. Furthermore we present a new electrical design with improved performance and better control possibilities. Based on the new design we show a method for an easy but nevertheless robust control mechanism of the actuator using an asymmetric three phase current system. Finally we present a functional demonstration of the new control algorithm in simulation and give a brief outlook on upcoming research activities.

“…Accordingly, Taipower has planned to install many wind turbines in the Penghu area. However, wind power output is not steady, and hence, the higher the wind turbine capacity is in the supply system, the greater the impact is on the electricity network [3][4][5][6][7][8]. Therefore, the economics of power generation is crucial for these islands.…”

Abstract:The abundant wind resources in the Penghu area, where the capacity factor of wind turbines can reach 45%, have inspired authorities to build more wind turbines in a diesel-based power system. However, because the wind turbine output is unstable, high wind power penetration in the system may relatively affect the power quality (voltage and frequency) and reliability of the system. Previous studies have suggested that the optimal penetration level for wind power generation under the present dispatching criteria in Penghu is 26.3%. The present study suggests that the criteria for current unit scheduling should be modified; in particular, the spinning reserve (SR) capacity of the diesel engines should be increased without affecting the reliability and power quality of the power system. Such an increase could help avoid the construction of high-cost energy storage systems.
