对新能源多场站短路比(multiplerenewableenergy stations short circuit ratio
MRSCR)进行改进,提出一种实时临界短路比(critical short circuit ratio
CSCR)指标的求取方法,实现静态电压稳定性判别标准与临界短路比算法的统一。首先,基于MRSCR的定义分析其优缺点及适用性,在此基础上结合所提出的计及新能源出力特性的扩展雅可比矩阵,得到了新能源多场站临界短路比的求取方法;其次,理论分析了MRSCR在不同因素影响下的变化规律;最后,依托电力系统全数字仿真装置(advanced digital power system simulator
