摘　　要：在简化配电网拓扑的基础上,应用混合粒子群算法对含分布发电单元的配电网重构问题进行求解。采用10进制编码进行简化求解,提出了基于节点–分层关联矩阵进行智能网络拓扑识别及分层前推回代的潮流计算方法。该方法可适应动态计算配电网潮流的需要,为实时动态重构提供新的思路。在网络重构中引入分布式电源,大幅降低了网损,对节点电压有较好的支撑作用。IEEE 33节点算例验证了该方法的有效性和合理性。On the basis of simplifying topology of distribution network and by use of hybrid particle swarm algorithm the reconfiguration of distribution network containing distributed generation （DG） is solved. To simply solve this reconfiguration problem by decimal coding, the node-layer incident matrix-based intelligent network identification and forward-backward sweep method-based power flow calculation method are proposed. The proposed methods can meet the requirement of dynamic calculation of power flow in distribution network and offer a new idea for real-time dynamic reconfiguration. The DG units are led into network reconfiguration, so network loss can be evidently reduced and provide a better support to nodal voltage. The effectiveness and reasonableness are verifed by calculation results of IEEE 33-bus system.
