Abstract:Multi-infeed AC-DC hybrid system is the notable form of China’s power grid upgraded because of the distribution of the generation and load. Multiple high-capacity high voltage direct current transmission lines enhance the transmission capacity, while the problem of small signal stability will emerge new features. As the complexity of the power grid increases, the small signal stability problem faced by multi-feed AC-DC power systems becomes more severe, and a specific theoretical analysis is urgently needed. The article introduced the typical structures and characteristics of multi-feed AC-DC hybrid systems. The system dynamic interaction mechanisms and the stability problems under the small signal stability caused by AC-DC system interaction were reviewed. The research methods and their achievements in this field were summarized. The future developing trend of multi-feed AC-DC hybrid system and the challenges were discussed to provide references for related research work at last.
