风电场储能容量合理取值范围分析

Analysis of reasonable wind farm energy storage capacity range

风电场配置适当的储能容量可以有效改善因风速变化而造成的输出功率波动。针对怎样选取储能容量较为经济合理问题,在结合一种所需储能容量计算方法的基础上,提出了评判风电场输出改善效果的两种指标。通过详细分析储能容量合理取值受到的各种影响因素,利用储能容量成本及风电场输出功率平滑效果辅助判据,得出风电场储能容量合理的取值范围。

The wind farm output power fluctuations caused by changing wind speed can be improved by configuring the appropriate storage energy capacity .For the problem that how to select the storage capacity more economical, two indicators for the judgment of the optimization wind power output are mentioned, which is based on a method calculating storage energy capacity. By detailed analysis of the all kinds of factors that can influence the reasonable value of storage capacity, and by using the cost of storage capacity and the smoothing effect of wind farm output as assistant criterion, a reasonable storage capacity range is discussed.
