摘要

在电力系统恢复决策中，如果不考虑输电线路的失效风险，将导致恢复方案风险增大，甚至造成恢复的失败。为此，该文提出一种计及输电线路失效风险的电力系统分区恢复的动态决策方法，根据恢复过程中输电线路失效场景的变化动态调整分区恢复方案。首先，分析输电线路失效对分区恢复过程的影响；然后，刻画输电线路失效前后恢复逻辑的连续性约束，构建基于风险理论的恢复风险指标和基于恢复密度的分区恢复进程差异指标，建立考虑线路失效场景的分区恢复动态优化模型；最后，采取时间窗滚动优化和前瞻到底滚动优化相结合的方法进行优化求解，新英格兰10机39节点系统算例的仿真结果表明，所提方法能有效降低恢复风险。

Abstract

In the decision-making of power system restoration

if the failure risk of transmission lines is not considered

the risk of restoration scheme will increase

and even lead to the failure of restoration. In this paper

a dynamic decision-making method for power system partition restoration considering transmission line failure risk is proposed. The partition restoration scheme is dynamically adjusted according to the change of transmission line failure scene during the restoration process. Firstly

the influence of transmission line failure on the partition restoration process is analyzed. Then

the continuity constraints of restoration logic before and after transmission line failure are described. The restoration risk index based on risk theory and the difference index of partition restoration process based on restoration density are constructed

and the dynamic optimization model of partition restoration considering line failure scenario is established. Finally

this paper combines the time window rolling optimization and forward-to-the-end rolling optimization to solve the optimization problem. The simulation results of the New England 10-machine 39-bus system show that the proposed method can effectively reduce the restoration risk.
