摘要
为了促进风能的利用与发展,减小风力输出波动的技术是不可或缺的。文章对应用于风力发电系统存储电池的电池功率与电池容量进行计算分析,并提出了一种推导最佳电池容量了判据方法。该方法采用时间常数-合成输出标准偏差特性,结合对风电平滑的效果,依据成本/性能比得出最佳的电池功率与电池容量。研究结果对嵌入风电场的储能系统参数的选定具有一定的参考价值。
The technology for reducing wind power fluctuation is very important for the development of wind energy.The paper analyses the power and capacity of storage batteries dedicated for wind power system,and proposes a new criterion for deriving the optimal battery capacity.With this method,the optimal battery capacity is obtained on the basis of cost performance analysis by using the time constant-normalized standard deviation characteristics.The results can be used as a reference for selecting the energy storage system parameters of wind farm.
