首先讨论了电力系统的拓扑特征，提出了一种基于遗憾概念的节点重要性评价方法，然后通过寻找平均重要性最大的路径来选择最优恢复路径，然后采用两阶段策略对网络重构过程进行优化。在第一阶段中，通过最大化恢复的发电量来确定发电机组的启动顺序，然后根据电力系统的恢复状态来选择串联或并行恢复模式。在第二阶段中，根据恢复的电力系统的状态，确定发电机组的启动顺序，然后根据系统的恢复状态来选择串联或并联恢复模式该方法选择平均重要度最大的路径对相关机组进行恢复，并考虑了输电线路与电力系统可能发生的故障连接，从而至少在一定程度上解决了现有方法中恢复路径和骨架网络分开确定的问题，为全面停电或局部停电后的电力系统恢复提供了一种新的途径。最后，以新英格兰10机39节点电力系统为例，验证了该方法的可行性。
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.
