Analyzing root causes of multiple plant-wide oscillation. Although multivariate Granger causality (MGC) was applied to find the root cause of plant-wide oscillatins, the existing works (Yuan, Qin, 2014, Xie, Wang, Xie, Yao, Liu, 2019) did not consider the multiple plant-wide oscillations. If MGC is used to analyze all variables with different ...
