基于主成分分析的风电场等值方法的研究

针对系统中含有多随机变量的问题，提出了采用主成分分析对多电源提取有效的主成分来进行等值，结合REI等值对网络进行化简的方法。算例分析中运用了主成分分析方法进行了多台风力发电机的主成分提取，将提出的主成分看成虚拟的等效风力发电机来替换原有的多台风电机组，实现了有效的简化替换，降低了系统分析的复杂性。

Studies on Wind Farm Equivalent Method Based on Principal Component Analysis

Power systems Contains a large number of random power supply, load and other random varia- bles. For the issue of system containing multiple random variables, the method of equivalent using the principal component by principal component analysis method and Combining with REI equivalent was pro- posed. The principal components of multi-wind farm were extracted, and the principal components were seen as the virtual equivalent wind turbines. As a result, simplified replacement was effectively implemen- ted, and the complexitv of systems analysis was reduced.
