Abstract

This paper discusses the application of a nonlinear analysis method based on the proper orthogonal decomposition (POD) method and Galerkin projection to the analysis and characterization of nonlinear modal interaction in stressed power systems. Using Galerkin projections onto bases of eigenfunctions obtained from the POD method, a new model is constructed that determines approximate solutions to the nonlinear power system behavior. The practical use of these methodologies is tested on a two area, 4-generators test system model. The validation is based on comparison with results from transient stability analysis using a commercially available transient stability program.
