Power flow algorithm for the weakly meshed distribution network with DG

针对含有分布式能源的弱环配电网的结构特点,将配电网网络结构分解为辐射状主网络和弱环状的子网络2大部分.充分利用不同潮流计算方法的优势对每一种网络进行分析,再通过联络支路将结果统一并参与迭代.通过对IEEE 33节点系统的仿真,对所提出算法的精度、计算速度、实用性等进行了分析,证实了算法的可行性和有效性.

According to the structure feature of the weakly meshed distribution containing distributed generation （DG） ,the weakly meshed network is divided into two networks： radial network and weakly meshed network. Each network power flow is solved by use of the advantages of different power flow calculation methods. The solutions of two networks are superposed together. A lot of simulations with IEEE 33 buses system are carded out to illustrate the performance of the proposed method. Test result verifies the feasibility of the proposed algorithm.
