摘要:

极端灾害会对输配电网造成不同程度的破坏,影响电力系统正常运行。在故障发生后,合理的恢复策略有利于快速恢复供电,减少停电损失。针对极端灾害造成输配电网同时多重故障的场景,提出一种可以统筹输配电网资源的基于多时段安德森加速的输配协同灾后恢复策略。以恢复过程中最小运行成本为目标函数,计及输配电网的机组运行状态、故障修复顺序,并同时考虑配电网的灵活资源响应、故障修复顺序以及网架重构和孤岛划分策略,采用全并行目标级联分析法对模型进行求解。为了解决由网架拓扑变化带来的目标级联分析法内循环收敛性差的问题,将扩展到多时段的安德森加速法应用于求解过程。T30D2和T57D8算例表明,所提方法不仅可以有效降低灾后恢复过程中的失电损失,还可以显著提高计算速度,并且对于接入多个主动配电网的大规模网架有良好的适应性。

Abstract:

Extreme disasters can cause varying degrees of damage to the distribution and transmission networks, affecting the normal operation of the power system. After a failure occurs, a reasonable recovery strategy is beneficial for rapidly restoring power supply and reducing outage losses. Aimed at scenarios where extreme disasters cause simultaneous multiple failures in distribution and transmission networks, this study proposes a collaborative post-disaster recovery strategy for distribution and transmission networks based on multi-period Anderson acceleration, which coordinates resources of both networks. The strategy targets minimizing operational costs during the recovery process, considering the operational status of generating units in the transmission network, the sequence of fault repairs, and also incorporates the flexible resource response of the distribution network, fault repair sequence, network reconfiguration, and islanding strategies. A fully parallel objective-level cascade method is adopted to solve the model. To address the issue of poor convergence in the inner loop of the objective-level cascade method caused by changes in network topology, an extended multi-period Anderson acceleration method is applied in the solving process. The T30D2 and T57D8 test cases demonstrate that the proposed method can effectively reduce the power outage losses during the post-disaster recovery process and significantly improve computational speed, showing good adaptability for large-scale networks with multiple active distribution networks integrated.
