中文摘要：

以东北某风场的实测风电功率数据为例,提出风电波动系数指标,分析风电机组汇聚时区域风电出力波动的变化规律,结合集对分析理论,研究在不同时空尺度下,同一度和重度差异的变化特性.对风电功率汇聚进行量化分析,为研究风电功率相关性提供新思路.

英文摘要：

Taking the measured wind power data of a wind farm in northeast area as an example, the wind power fluctuation coefficient index was proposed to analyze the variation principal of regional wind power output fluctuation in wind turbine aggregation area; the change characteristics of the same degree and severe difference under different time and space scales were studied with set pair analysis theory. Aggregation of wind power was analyzed quantitatively to provide a new way to study the correlation of wind power.
