Summary:
We review the Koopman Mode Analysis (KMA) for nonlinear spatio-temporal dynamics and report its application to power system analysis. KMA is a natural extension of the traditional linear mode analysis and is based on spectral theory of dynamical systems. For a given data on highly nonlinear dynamics, it gives a set of spatial modes of oscillation with single frequency. KMA is used for analysis of swing dynamics in a group of synchronous machines that are of vital importance for planning and operation of electric power systems.
