基于风速相关性风电场储能容量配置定量研究

为研究风速相关性对风电场储能容量的影响,首先建立了风速ARMA模型,并根据时移技术得到风电机组风速分别呈高度、中度和低度三种不同相关度的风电场的风速时间序列,最后对不同相关度下的风电场的储能容量进行定量分析。结果表明,合理布置风电场能在较好利用风能的情况下有效减少风电储能成本和土地资源的浪费。

Study on wind field energy storage capacity considering wind speed correlation

In order to analyze the effect of wind speed correlation on wind field energy storage capacity,the ARMA model of wind speed time series (WSTS) was built;the time-shifting technique was used to produce three wind speed time series in three different fields in different correlation degrees (high,moderate and low) with the initial WSTS;the energy storage capacity of three wind farms was calculated.The results indicate that the rational layout of the wind farm can not only be useful for efficient utilization of wind energy,but also effectively reduce the energy storage cost and the waste of land resource.
