Abstract

Due to the inherent fluctuation nature of wind power, voltage control and frequency regulation in China's power grid become more intricate as the wind power penetration level increasing. Provided with traits of comprehensive response and bidirectional output, wide concern has been arisen by the hybrid energy storage system (HESS), while how to design a smooth strategy is vital to achieve great effect. In order to conform the fluctuation of the wind power to China's technical standards, based on a HESS composed of electrical double layer capacitors (EDLCs) and battery, this paper proposes a strategy utilizing wavelet threshold filtering and mean-value interval as first and second smooth step, to flat the high and low frequency components of wind power fluctuations respectively. Taking a wind farm as an illustration, the validity of this strategy is verified by the calculation and analysis.
