摘　　要：为解决前推回代复仿射潮流算法在弱环及多分布式电源(DG)接口类型配电网中的适用性问题,在详细分析前推回代复仿射潮流计算特点的基础上,引入基于道路矩阵的回路分析法来解决该适应性问题。随后,针对仿射算术无法在区间不确定性条件下准确描述DG无功控制特性的不足,采用无功灵敏度矩阵与电压灵敏度矩阵两步修正的方式,提出了可计及DG无功控制特性的复仿射潮流改进算法。最后,基于IEEE 33节点系统、PG&E 69节点系统以及实际113节点系统扩展的含多DG接口类型的不同规模配电网验证了所提算法的有效性与准确性。In order to solve the applicability problems of the back/forward sweep complex affine arithmetic based power flow(CAA-PF) algorithm to the weak-mesh distribution with multi-type of distributed generators(DGs), based on the detailed calculation characteristics analysis of the back/forward sweep CAA-PF algorithm, the loop analysis based on path matrix is adopted. In terms of the limits of the affine arithmetic in describing the reactive power uncertainty characteristics of DG, an improved CAA-PF algorithm using two-step correction of the reactive power and voltage sensitivity matrices is developed. Tests on the modified distribution networks with different scales based on the IEEE 33-node system, PG&E 69-node system and a real 113-node system with multi-type DG interconnections validate the effectiveness and applicability of the proposed algorithm.
