Abstract

In this paper investigation of nonlinear modal interaction using the normal form of vector fields technique is extended to HVDC/AC power systems with do power modulation. The ae-dc interface equations are solved to form a state space model with second order approximation. Using the normal form technique, the system's nonlinear dynamic characteristics are obtained. The proposed approach is applied to a 4-generator HVDC/AC test power system, and compared with the time domain solution.
