论文摘要
本文探讨了在网格形成的杂种角控制策略下非同步混合AC/DC功率网格的稳定性。我们为AC网格和传输线，相互链接转换器以及DC世代和互连制定动态模型。接下来，我们确定了整个系统的闭环平衡的存在和独特性。随后，我们证明了平衡，所需平衡点的局部渐近稳定性以及其他平衡的吸引力区域的全球渐近稳定性。理论结果是在轻度，参数和统一的稳定/不稳定性条件下得出的。最后，依靠中间结果，我们结论了混合AC/DC功率网格的几乎全局渐近稳定性，其相互链接转换器配备了混合角度控制。最后，我们介绍了正在调查的问题的实际和理论方面的几篇评论。
This paper explores the stability of nonsynchronous hybrid ac/dc power grids under the grid-forming hybrid angle control strategy. We formulate dynamical models for the ac grids and transmission lines, interlinking converters, and dc generations and interconnections. Next, we establish the existence and uniqueness of the closed-loop equilibria for the overall system. Subsequently, we demonstrate global attractivity of the equilibria, local asymptotic stability of the desired equilibrium point, and instability and zero-Lebesgue-measure region of attraction for other equilibria. The theoretic results are derived under mild, parametric, and unified stability/instability conditions. Finally, relying on the intermediate results, we conclude the almost global asymptotic stability of the hybrid ac/dc power grids with interlinking converters that are equipped with hybrid angle control. Last, we present several remarks on the practical and theoretical aspects of the problem under investigation.
