Special Session: Advanced Analysis, Monitoring and Control Technologies for Wide-band Oscillation in New Power Systems

This theme focuses on critical wide-band oscillation issues in new power systems, covering five core directions: First, investigating new phenomena and underlying mechanisms of wide-band oscillations caused by grid-forming controlled high-penetration renewable integration; Second, exploring oscillation challenges in large-scale multi-machine systems with grid-forming converters and proposing innovative modeling and analysis methods; Third, developing new technologies for wide-area monitoring, precise source tracing, and effective suppression of wide-band oscillations; Fourth, establishing intelligent risk identification and early warning systems for oscillation in high-renewable power systems; Fifth, integrating AI technologies to develop intelligent solutions for oscillation monitoring, analysis, and control. These research directions will systematically address stability challenges under high renewable penetration, providing theoretical foundations and technical support for building safe and reliable next-generation power systems.

This session focuses on the most cutting-edge and urgent wide-band oscillation challenges in power system transformation, demonstrating unique significance. First, the wide-band oscillation emerging in high-penetration renewable energy integrated power systems with grid-forming control participation is a relatively new oscillation phenomenon, whose generation mechanism differs from traditional power system stability issues and is difficult to incorporate into conventional stability frameworks. Second, oscillation problems in large-scale multi-machine systems incorporating grid-forming converters transcend traditional power system analysis frameworks, necessitating entirely new modeling theories and methodological systems. Third, wide-area monitoring and suppression technologies for wide-band oscillations involve multi-time-scale and multi-frequency-band coupling, far exceeding the scope of conventional oscillation monitoring. Fourth, oscillation risks in high-penetration renewable energy systems exhibit high nonlinearity and uncertainty, rendering traditional risk assessment methods ineffective. Fifth, the deep integration of artificial intelligence with power system stability represents the frontier of interdisciplinary convergence, which conventional agendas struggle to accommodate. These topics represent the most advanced directions in global power system research, requiring dedicated technical exchange platforms. Conventional conference agendas cannot systematically cover the complete technical chain and interdisciplinary characteristics of this emerging field, thus necessitating a specialized session to drive theoretical and technological innovation.
