Application of Energy Storage System in Mitigating the Flicker Resulted from Integrated Wind Power Generation
摘要
Abstract
A great deal of fluctuation contain in the integrated wind power generation, which will result in voltage flicker on the point of common coupling. When wind farms are integrated into low-voltage distributions, the traditional reactive-power-based methods of flicker mitigation show their limits. Consequently, a novel energy storage-based method for the flicker mitigation purpose was proposed in this paper, in which a supercapacitor was selected as a storage medium, and the structure of the voltage source converter cascade bidirectional DC/DC converter was used in power conditioning system. The wind power through a low-pass filter was considered as the control objective, and the control strategy of the energy storage system was established to track the active power. Regarding a wind model with wind shear and tower shadow effects as the input, power fluctuation and flicker values were compared before and after the installation of storage system. The effectiveness of the scheme and corresponding control strategy were justified by the simulation results.关键词
