    摘要:

    智能配电网的发展提升电网的自愈能力和恢复速度,然而,当系统遭遇大范围停电事故时,其恢复过程颇为复杂。因此,针对受损配电网供电中断问题,提出一种计及冷负荷效应的受损配电网两阶段恢复策略,用以生成含开关控制动作的配电网供电恢复策略。先生成支持馈线重配的传统恢复和分布式电源辅助的孤岛供电恢复计划。然后,生成最优开关切换操作序列,将其转化为混合整数线性规划(mix integer linear programming, MILP)问题,使受损配电网快速恢复到最终配置。最后,使用多馈线1 069节点电力系统中模拟单线与多线故障时的配电网恢复策略。研究结果表明,所提策略能有效生成开关切换动作序列,合理利用所有资源快速恢复配电网,提高受损配电网的恢复速度与容量。

    Abstract:

    The development of intelligent distribution networks has improved the self-healing ability and recovery speed of the power grid. However, when the system encounters large-scale power outages, the recovery process becomes more complex. Therefore, in response to the problem of power interruption in damaged distribution networks, this paper proposes a two-stage recovery strategy for damaged distribution networks that takes into account cold load pick-up (CLPU), aiming to generate a power restoration plan for distribution networks with switch control actions. The first stage generates traditional recovery and distributed power-assisted island power supply recovery plans that support feeder reconfiguration. In the second stage, the optimal switching operation sequence is generated and transformed into a mixed integer linear programming (MILP) problem, which enables the damaged distribution network to quickly recover to its final configuration. Finally, a distribution network recovery strategy is simulated in a multi-feeder 1069-node power system for single- and multi-line faults. The results show that the proposed strategy can effectively generate switching operation sequences, make reasonable use of all resources to quickly recover distribution networks, and improve the recovery speed and capacity of damaged distribution networks.
