摘　　要：对电力系统恢复过程中目标骨架网络的重构问题进行了研究。利用复杂网络中节点介数相关理论,提出了一种兼顾拓扑优先与路径电气影响的网络重构方法。该方法计及了线路充电电容对网络节点重要性的影响,从而实现对加权输电网络的重构,提出的重构效率指标综合考虑节点重要性和送电线路优化对重构网络的影响,实现了重构骨架网络的整体优化。利用遗传算法易于处理离散变量且具有全局收敛性的特点,对该优化问题进行求解。最后以IEEE30节点和IEEE39节点系统为例,验证所提方法的有效性。The reconstruction of target power transmission network in power system restoration process is studied. By using related theory of node betweenness in complex network, a network reconfiguration method, taking both topology priority and path electrical effects into consideration, is put forward. This method takes account of the influence of shunt capacitance on node importance, so as to realize the reconfiguration ofweighted power transmission network. The index of reconstruction efficiency considering the effect of the node importance and transmission line optimization on reconstruction network achieves the whole optimization of the reconstructed network. The genetic algorithm method, which has the characteristics of global convergence and handling the discrete variables easily and effectively, is employed to solve this problem. Finally, the IEEE 30 and IEEE 39 bus system are applied as benchmark to demonstrate the validity of the proposed method.
