A Three-phase Decoupled Power Flow Algorithm for Weakly Meshed Distribution Networks Based on the Sequence Component
摘要
Abstract
In order to do power flow calculation efficiently for weakly meshed three-phase smart distribution network, the paper proposed a three-phase decoupled power flow algorithm based on sequence component. Firstly , three-phase decoupled power flow model of distribution system was established by using the sequence component method, and considering the characteristics of three-sequence decoupled and the three-sequence decoupling-compensation models of unsymmetrical branches. Then, based on the path and loop analysis method, an improved three-sequence power flow calculation method was presented. The proposed algorithm combines the computational efficiency of the sequence component method with the strong ability of processing loops of the path-loop analysis method, which improves the computational efficiency and speed. It has good convergence and strong ability of processing the loops. With the closing of the loops, the number of iteration will decrease. The case studies verify the correctness, effectiveness, good convergence, fast computational speed and strong ability of processing the loops of the proposed algorithm.关键词
