Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we study a method to reduce the dimension on highly-resolved time series data of voltage phasors measured at our university campus while preserving important information.
Specifically, we focus on eigenvalues and modes of the Koopman operator for an underlying nonlinear dynamical system as important dynamical information, and we use the Koopman mode decomposition as an estimation technique for them. By using the decomposition, we extract oscillatory components that contribute to the error reduction between the reduced data and the original data.
