摘　　要：在配电网重构的研究中,通常会对网络的稳态运行进行优化,但是重构方案对网络故障情况下的可靠性也会产生影响。在考虑到分布式电源出力与负荷波动的情况下,为兼顾网络运行的经济性与可靠性,减少新能源接入带来的负面影响,搭建配电网动态重构模型。首先,针对分布式电源接入的配电网,采用启发式孤岛搜索方法,并结合最小路法来求解可靠性指标;其次,以包含开关费用、线损费用与停电损失费用在内的网络综合成本最小为目标函数,搭建网络动态重构模型;然后,采用改进的混合天鹰-非洲秃鹫算法进行模型求解;最后,通过在改进的IEEE33节点网络上进行仿真验证了模型的有效性。In the research on distribution network reconstruction,the steady-state operation of the network is usually op-timized,but different reconstruction schemes may also have an impact on the network reliability under fault conditions.To take into account the economy and reliability of network operation and reduce the negative impact of new energy ac-cess,a dynamic reconstruction model of distribution network is built under fluctuations in the output from distributed generations(DGs)and load.First,for a distribution network with the access of DGs,the heuristic island search method is used,and the minimum path method is combined to solve the reliability indexes.Second,a dynamic network re-construction model is constructed with the minimum comprehensive cost of the network as its objective function,including the switching cost,line loss cost and power outage loss cost.Third,an improved hybrid Aquila optimizer and African vultures optimization algorithm is used to solve the model.Finally,the effectiveness of the proposed model is verified by simulations of a modified IEEE33-node network.
