Abstract：With the increasing penetration of renewable energy sources, especially the wind power generation, and broad application of the high-power power electronic technology, electric power system with renewable energy sources is evolved, which is constituted by complicated AC-DC system with multi energy resources and multi conversions. As a result, new subsynchronous oscillation (SSO) problems are prominent constantly. The concept and connotation of SSO is extended gradually. And various intricate issues, such as their causes, forms, impact, monitoring and countermeasures attract wide attention throughout the world again. This paper firstly summarizes the basic issues and development trend of SSO, and analyzes the characteristics and forms of SSO problems in China. Finally, new issues of current SSO research, challenges ahead, especially in mitigation measures, and the corresponding strategies are put forward, aiming at promoting the SSO study in China.
