摘要
牛顿—拉夫逊法是求解潮流计算的有效方法,但当初值选择不当,有可能不收敛,且受R、X比值影响较大。本文提出了基于改进蚁群算法的配电网潮流计算方法,利用Matlab编程实现。计算结果表明,该方法解决了牛顿—拉夫逊算法对初值敏感问题,使潮流计算的收敛过程得到有效地控制,提高了算法的稳定性。
Newton - Raphson method for solving power flow calculation is an effective method, but when the initial value of options is not so good, it may not converge, and are subject to R, X ratio greater impact. In this paper, it proposed a way which based on improved ant colony algorithm for distribution power flow calculation method., using Matlab programs.The calculation results show that the solution to the Newton - Raphson algorithm is sensitive to the initial value problem, so that the convergence trend of the calculation process was effec- tively controlled and improve the stability of the algorithm.
