摘要
Power system stability can be analyzed from the perspective of dynamic interactions among multiple modes. Modal interaction provides a new insight into phenomenon such as local modes causing inter-area oscillations. In recent years, the meaning and phenomenon of modal resonance have expanded from synchronous generator lowfrequency resonance to renewable energy wideband oscillation. To understand modal resonances under the background of power electronics dominated power systems, this paper first introduces the meaning of traditional modal resonance, and proposes the classification of generalized modal resonance. Then, the modal resonance phenomenon in practical power systems and its hazards are summarized. Meanwhile, the theoretical analysis of generalized modal resonance is reviewed. Finally, future research on modal resonances is discussed.
