The new power system is characterized by "dual-high" (high proportion of renewable energy and power electronic equipment) and "dual-large" (large-scale renewable energy bases and large-capacity AC/DC transmission channels). This forum focuses on two core topics: "security defense" and "intelligent flexible control", aiming to explore cutting-edge technologies and innovative theories for ensuring the safe and stable operation of new power systems. In the field of "security defense", key discussions include fault characteristics and new protection principles for "dual-high" power systems, relay protection for UHV AC/DC systems and nearby grids, safety prevention technologies for large power equipment, and strategies against cascading failures under extreme disasters. For "intelligent flexible control", emphasis is placed on addressing stability risks caused by high uncertainty and strong nonlinear interactions, transient frequency/voltage instability under large-scale power electronic applications, and coordinated control of heterogeneous power electronic devices.

新型电力系统呈现高比例新能源、高比例电力电子装备以及大规模新能源基地、大容量交直流通道的“双高”“双大”特点。本分论坛聚焦“安全防御”与“智能柔性控制”两大核心议题，旨在深入探讨保障新型电力系统安全稳定运行的前沿技术和创新理论。在“安全防御”领域，重点讨论“双高”电力系统故障特征与保护新原理、特高压交直流系统及近区电网继电保护、大型电力主设备继电保护与安全防控技术、极端灾害下系统连锁故障风险及恢复策略等问题；在“智能柔性控制”领域，重点讨论如何应对系统高不确定性、强非线性交互作用带来的稳定风险、电力电子装备规模化应用下的暂态频率/电压失稳、异构电力电子装备协同控制等新问题。
