Root cause diagnosis of plant-wide oscillations using Granger causality.

Highlights: [•] The paper presents a new data-driven time series method for diagnosing the sources of plant-wide oscillations. [•] The proposed method combines the Granger causality, spectral Granger causality, and principal component feature selection. [•] Simulation and industrial case studies demonstrate that the effectiveness of the proposed method. [Copyright &y& Elsevier]
