Abstract

Discontinuous transient dynamics are examined for an electric power system with dc transmission. A differential-algebraic equation (DAE) system is proposed for transient stability analysis of an ac/dc power system. When the transient stability analysis is performed using the DAE system, trajectories that represent the dynamics of ac/dc power system become discontinuous. This paper is devoted to intensive studies on such discontinuous solutions of the DAE system and associated transient dynamics of the ac/dc power system. Some examples of discontinuous solutions of the DAE system are exhibited, and it is shown that the discontinuous solutions are tractable in both numerical and analytical senses.
