随着电网运行方式日趋复杂，传统的输配一体化潮流计算面临收敛性恶化的问题，针对这一现状，该文提出一种基于安德森加速的输配一体化潮流计算方法。首先将输配一体化潮流计算抽象为简单的不动点迭代形式，利用不动点迭代理论对其进行收敛性分析。接着，根据潮流计算的迭代本质，结合不动点领域中安德森加速的思想，提出基于安德森加速的输配一体化潮流计算方法。然后利用环网等效的方法提高该方法处理环网时的收敛性能。最后，在算例分析部分，首先验证了所提方法的精确性，然后在多个场景下比较该文方法和已有方法的收敛性能，验证了所提方法在收敛性能上的优越性。 

With the increasing complexity of power grid operation mode, the convergence of traditional integrated power flow calculation is deteriorating. In view of this situation, this paper proposed an anderson-acceleration-based power flow method. Firstly, the integrated power flow calculation of transmission and distribution networks was abstracted into a simple fixed point iteration form, and its convergence was analyzed by using the fixed point iteration theory. Then, according to the iterative nature of power flow calculation, combined with the idea of anderson acceleration in the fixed point field, the anderson-acceleration-based power flow method was proposed. Besides, the equivalent method was used to improve the convergence performance of the method in the network with loops. Finally, in the part of case study, the accuracy of the proposed method was verified firstly, and then the convergence performance of the proposed method was compared with the existing methods in various scenarios; hence the advantages of the proposed method in convergence performance were verified.
