English: The new power system is confronting multiple challenges arising from the large-scale integration of high-proportion renewable energy and the transition toward power-electronicization. A large number of power electronic converters are replacing traditional synchronous units, leading to reduced system rotational inertia and prominent multi-scale coupling interactions among equipment. Coupled with the random fluctuations of renewable generation, problems such as broadband oscillation, insufficient voltage and frequency support, and altered fault dynamic characteristics have become increasingly prominent. Traditional analysis theories and control methods can hardly fully adapt to the complex dynamic behavior of power-electronicized grids, and related technologies for modeling, stability analysis, and operation control urgently need breakthroughs. This special session focuses on power-electronic power systems with high penetration of renewable energy, discussing key technologies for system modeling and simulation, stability analysis, and operation control. In terms of modeling and simulation, it addresses multi-time-scale equipment modeling, interaction mechanisms of converter clusters, and efficient electromagnetic–electromechanical hybrid simulation methods. In terms of stability control, it concentrates on the identification, analysis, and suppression of broadband oscillation, coordinated control of grid-forming and grid-following equipment, and voltage–frequency support technologies for low-inertia systems. In terms of operation applications, it emphasizes source–grid–storage multi-resource coordinated optimization, fault ride-through and protection adaptation, digital-intelligence technologies, and engineering practice cases. The session aims to bring together researchers and engineering technicians in related fields to exchange theoretical progress and application experience, providing technical references for the safe and stable operation of new power systems with high-proportion renewable energy and power-electronicization.
