Xiangjun Li, Jingqiong Zhang, Yuting He, Dongbin Zhao · 2016
Based on the rate control method of the wind power fluctuation, this paper proposes an adaptive dynamic programming (ADP) based method to optimize the power of battery energy storage systems (BESS) adaptively. On the one hand, this method can be used to adjust the unstable wind and BESS hybrid power output so as to satisfy the requirements of wind power. On the other hand, this method can be used to control the battery state of charge (SOC) maintained within a suitable range, to achieve a reasonable charge and discharge function of the battery. Take a typical wind farm's output as example, under the limitation of wind power volatility and battery state of charge, this paper shows the experiment that through the real-time online optimization of the smoothing process. The simulation results show the effectiveness and feasibility of the proposed coordinated control strategy based on ADP.
