Abstract
Chaos in power systems is similar to the phenomena of random and continuous oscillations. It is absolutely forbidden in power system operation. Because of its extreme complexity, chaos has brought evident influence to the studies of power system stability and preventing of instability. Its mechanism, however, has been known very few. In this paper relationship of chaotic phenomena and instability modes are studied in order to ascertain the possible spot of chaos in the evolution of power system instability contingencies. In the studies, it is found that chaos can lead power system to voltage collapse, angle divergence, or voltage collapse and angle divergence simultaneously, when their stability conditions are broken. Based on the above studies, it is derived that chaos is possibly existing in power system as an intermediate stage of large disturbance instability incident.
