摘　　要：正确把握交直流相互作用的机理,是综合考虑各种安全约束协调各种控制措施优化控制策略的重要依据。为此,针对交直流多直流交互作用的电力系统安全稳定、交直流协调控制问题研究归纳总结,梳理和评述了各研究热点的现状及应用,分析了交互安全影响的机理。建议从交直流系统安全稳定交互安全影响的机理入手,研究各种交直流运行方式和直流控制方式对安全稳定模式的影响,揭示交直流相互作用的现象和本质,协调各种控制措施,综合考虑各种安全约束,优化控制策略。The understanding of the mechanism of interaction between AC and DC is an important basis for considering various security constraints and optimizing the control strategy for various control measures. This paper analyzes the interactive mechanism of power system, and summerizes the following aspects in the coordination control of multi-infeed DC and AC/DC hybrid power grid ： the security and stability in AC/DC systems, and the coordination control of AC/DC. The development and application in these hot research areas are reviewed and commented. It is suggested that based on the interactive mechanism of security and stability in the AC/DC system, the effects of various AC/DC operation conditions and DC control modes on the system security and stability should be studied to reveal the phenomena and essen- tials of AC/DC interaction, and control strategies should be coordinated and optimized considering all security constraints.
