摘要 根据配电网的特点,在比较各类算法的基础上提出了一种新的基于牛顿法的配电网潮流算法。该算法从Zbus算法出发,对网络方程进行虚实部分解,形成的雅可比矩阵与节点导纳矩阵有极大的相似性,迭代中雅可比矩阵仅有少部分对角元素需要修改。算法通过修改雅可比矩阵元素来处理PV节点,还能够处理几种不同类型的负荷模型。理论分析和计算表明该算法性能优良,是配电网络潮流分析的有效方法。 According to the features of distribution network and comparing the existing power flow algorithm, a new Newton method based power flow algorithm for distribution network is presented. Starting from Zbus algorithm the network equation is decomposed into real and imaginary parts, the formative Jacobian matrix is much similar to the nodal admittance matrix. In the iteration of Jacobian matrix only a fraction of diagonal elements should be modified. In the presented algorithm the PV nodes are processed by Jacobian matrix as well as some different types of load models. The results of theoretical analysis and calculation show that this algorithm possesses good performance and can be effectively applied to the power flow analysis of distribution network.
