紧急负荷调节用于安全稳定紧急控制的研究

为了应对某些场景下紧急控制措施难以实施的问题，并尽可能提高对用户供电的友好性和安全稳定紧急控制的精准度，提出将紧急负荷调节作为安全稳定紧急控制手段。从安全稳定紧急控制的角度分析紧急负荷调节的典型特征；基于扩展等面积准则(EEAC)剖析紧急负荷调节特性影响暂态稳定控制效果的机理，并与常规紧急切负荷控制进行对比，研究紧急负荷调节特性变化对暂态稳定紧急控制效果的影响。基于实际电网，仿真分析紧急调节电解铝负荷用于安全稳定紧急控制，验证了分析结论。

Research of emergency load regulation for security and stability control

To cope with the problem that emergency control measure is difficult to implement under some scenes and improve the friendliness of user power supply and accuracy of security and stability control, emergency load regulation for security and stability control is studied. In the view of stability emergency control, the characteristic of emergency load regulation is analyzed. Compared to emergency load shedding, the mechanism of the effects of emergency load regulation for stability control is studied based on EEAC (Extended Equal Area Criterion), of which the control result is influenced by emergency load regulation performance. The conclusion is verified by simulating and analyzing emergency regulation electrolytic aluminum load for stability control in real power grid.
