China’s power system is undergoing a profound transformation driven by the “dual-carbon” targets. With the large-scale integration of power electronics-based resources, system stability issues have become increasingly prominent, exhibiting strong coupling among multiple stability phenomena and unpredictable collective behaviors. To address these challenges, the limitations of the existing grid integration management framework is systematically analyzed, including the “black-box” external characteristics, inadequate grid integration testing system, and insufficient modeling accuracy. Drawing on international best practices, a new management framework is proposed, centering on the standardization of grid-connected control frameworks and model transparency. Comprehensive enhancement measures are proposed, covering the development of standardized control models and parameter tuning methods, technical standard revision, grid integration testing and simulation modeling optimization, digital monitoring, and market incentive mechanisms. The proposed framework aims to transform grid integration management from passive adaptation to proactive deep coordination, thus improving the secure and stable operation of new power systems.
