储能参与风电并网系统的波动平抑控制研究
|
摘要
基于风电并网导致电网调频压力大、波动性新能源并网难以消纳的背景,从储能电池在"源侧"进行风电功率波动平抑和在"网侧"进行频率波动平抑两方面研究储能系统频率控制方法。利用功率谱密度(PSD)分析风电出力特征,结合区域电网仿真模型,在两种风电作用场景下,对储能在电网的两种作用模式进行仿真分析。结果表明,针对"高频低幅"特点的并网风电,储能电池在"源侧"的平抑波动作用模式能起到较好的效果,提高电网稳定性;针对紧急高幅值的功率缺额,"源侧"的平抑波动作用模式效果并不显著,储能在"网侧"的调频作用模式能更好地提高电网抗干扰能力。
Under the background that the new energy is difficult to absorb in grid and the growing pressure in frequency regulation,the study are from two aspects for energy storage batteries,that is in the " source side" to adjust the new energy power output fluctuations and in the " network side" to support the grid frequency regulation. It was studied and compared by the simulation for regional power grid simulation model combined with the actual output power data of a wind farm. The results show that,energy storage battery in the " source side " of suppressing fluctuations mode of action can play a better effect for the " high frequency and low amplitude" characteristics of gridconnected wind power; for the case emergency high amplitude power vacancy,energy storage in the " network side" in the frequency regulation mode of action can play a better part to improve the anti-interference effect of the grid.
