摘　　要：首先研究了复杂电力网络的拓扑特性,发展了一种基于后悔思想的节点重要度评价新方法,并在此基础上提出了用于选择恢复路径的最大路径平均重要度方法。然后,采用分步方法制定网络重构策略:第1步优化发电节点的恢复顺序,以最大化恢复系统可用发电容量为目标,并根据恢复状况确定串行或并行恢复方式;第2步优化恢复路径,每次选取路径平均重要度最大的候选路径恢复发电节点,同时考虑了恢复过程中线路投运失败的问题。这种方法在相当程度上避免了确定目标骨架网络和优化恢复路径序列这2个网络重构环节脱离的问题,为大停电后的系统恢复提供了新的思路。最后,以新英格兰10机39节点系统为例说明了所发展的模型和方法的基本特征。The topological characteristics of a power system are addressed first,and a new method is developed to evaluate the importance of a node based on the concept of regret.A method for selecting the best restoration path is next developed by finding the path with maximized average importance.Then,a two-stage strategy is employed to optimize the network reconfiguration process.In the first stage,the start-up sequence of generating units is determined by maximizing the restored generation capacity,and then the serial or parallel restoration mode can be selected based on the restoration state of the power system.In the second stage,the path with maximum average importance is selected to restore the generating unit concerned.The possible failure to connect a transmission line to the power system is also considered.The problem in the existing methods that the restoration paths and skeleton-network are determined separately could then be solved at least to some extent using the method proposed,and a new approach is obtained for restoring the power system after a complete blackout or local outage.Finally,the New England 10-unit 39-bus power system is employed to demonstrate the feasibility of the proposed method.
