基于混合储能系统的风电场调度策略
Hybrid Energy Storage Based Generation Scheduling of Wind Farms
摘要
Abstract
The fluctuation characteristics of wind power generating units are analyzed and a method to make wind farms participating power grid generation scheduling by use of hybrid energy storage equipments is proposed. Based on spectral characteristics of active power output of wind farm, low-pass filters are configured to decompose active power output of wind farm into high-frequency output and low-frequency output; the high-frequency fluctuation and low-frequency fluctuation in wind power output are smoothed up by fast response type of energy storage device and high-capacity type of energy storage device respectively to make the output of the combined system enable to track the generation scheduling, thus the task of generation scheduling can be fulfilled. According to different processing modes for high-and low-frequency output fluctuation, a joint scheduling model for high-and low-frequency output fluctuation and separate scheduling models for high-frequency output fluctuation and low-frequency output fluctuation are established. The validity of the proposed method is verified by simulation results. The proposed method can be suited to wind farms with stable wind regime, but also to the assessment on wind farms that have been put into operation.关键词
