摘　　要： 网络重构是大停电后电力系统恢复的重要阶段。在有风电场的电力系统中,风电场可以作为常规黑启动电源的辅助。在此背景下,首先发展了一种基于线路收缩评价线路重要度的方法;在此基础上建立了以最小化恢复风险和最大化骨架网络重要度为目标的多目标网络重构模型;之后,发展了一种自适应的网络重构决策方法。所提出的方法能够将网络重构优化和决策这两个环节统筹考虑,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。 Network reconfiguration represents an important stage in power system restoration after a blackout or local outage. In a power system with integrated wind farms,the wind farms can serve as auxiliary power supply for the conventional black-start generating units such as hydro and thermal units. Given this background,a new method is first proposed to evaluate the importance of a line based on the concept of line constriction. A multi-objective optimization model is next developed for determining the skeleton-network with the minimization of the restoration risk and maximization of the importance of the skeleton-network to be found as the two objectives. Then,an adaptive decision-making method for the network reconfiguration is developed. In the proposed method,two issues,i.e. the network reconfiguration scheme optimization and decision-making,are well coordinated,and this provides a new way of solving the power system restoration problem after a blackout or local outage. Finally,the New England 10-unit 39-bus power system is employed to demonstrate the feasibility and efficiency of the developed model and method.
