Special Session: Grid-Forming Technologies and Stable Operation Control of Power-Electronized Power Systems

With the large-scale integration of high-penetration renewables like wind and solar into the grid through power electronic converters, the power system is undergoing a rapid shift—from a traditional synchronous generator‑based regime to a new architecture dominated by power electronic devices. While this transition improves system flexibility and controllability, it also brings serious stability challenges, such as reduced inertia support, risks of wide‑band oscillations, and multi‑timescale coupling. Hence, advancing grid‑forming control technologies, innovating converter topologies and control strategies, and deepening the understanding of stable operation mechanisms in flexible AC/DC transmission and distribution systems have become essential to building a secure, reliable, and efficient new power system.

Topics of interest include, but are not limited to:

Topics:
* Grid Integration and Control Technologies for Renewable Energy
* Topology, Modeling, and Control of Power Electronic Converters
* Grid-Forming Control Strategies and Their Applications
* Modeling, Stability Analysis, and Control of Power-Electronicized Power Systems
* Power Electronics Technologies in Flexible AC/DC Transmission and Distribution
