摘要

为了提高配电网消纳清洁能源能力，进一步提升配电网供电可靠性，配电网合环运行受到越来越多的关注。针对传统前推回代法处理环网潮流时出现不收敛情况，结合回路分析法与前推回代法，提出一种含环网配电网改进潮流算法。通过分解支路电流，对环网分裂点电流进行补偿，改变其不收敛现象，并且通过Matlab进行数据仿真，验证了此算法的有效性和精确性。

Abstract

In order to improve the ability of clean energy consumption and the reliability of power supply

distribution network operation is attracting more and more attention. In view of the non-convergence of the traditional forward and backward substitution method

an improved power flow algorithm for distribution network with ring network was proposed by combining the loop analysis method with the forward and backward generation power flow algorithm. The branch current was decomposed to compensate the split-point current

and the non-convergence phenomenon was changed. The validity and accuracy of the algorithm were verified by data simulation with Matlab.
