Supplementary material for Discovering low-rank representations of large-scale power-grid models using Koopman theory

The file contains the code for the paper "Discovering low-rank representations of large-scale power-grid models using Koopman theory". 

The directory contains the following items:

1. DMD_IEEE (This is the DMD MATLAB implementation for IEEE 118 and IEEE 300 bus systems)

2. DMD_Ring_Grid (This is the DMD implementation on the Ring-Grid Network)

3. Addition folder contain other functions like implicitEuler solver, DMD file, MATPOWER library and pg_sync model (Nishikawa et al 2015)
