    摘要:

    合理的主动配电网(ADN)恢复力综合评估可反映随机故障后ADN恢复供电的能力,有助于采取有效措施提升恢复力以减少损失。考虑到在不同随机故障下节点存在交互影响,提出适应随机不确定性的主动配电网恢复力综合评估方法。首先基于节点故障恢复过程,建立节点完全恢复供电时长、节点断续供电时长和节点能量损失百分比3个恢复力指标,以评价节点恢复力;然后将多次随机故障下节点恢复力之间的交互影响量化表示,并以此确定节点权重,实现ADN整体恢复力综合评估;最后以IEEE 33节点模型作为中压配电网算例,蒙特卡洛仿真随机故障,通过所提方法可反映故障恢复措施实施后的恢复力提升效果,说明方法的有效性。

    Abstract:

    A reasonable comprehensive evaluation of distribution network resilience can reflect the ability of distribution network to restore power supplies when random faults occur, which is also helpful to diagnose the performances of different countermeasures for a higher resilience and lower losses. According to the mutual impacts by network nodes under different random faults, one comprehensive evaluation method for the resilience of active distribution networks (ADN) is presented to handle such an uncertainty. Firstly, three resilience indexes: fault recovery time, outrage time and energy loss percentage is established to comprehensively evaluate the resilience of node. Aiming at quantitatively rating the interactive influences of nodes caused by the network connectivity and distribution energy resource (DER) location in a fault event, this paper retains the data information characteristics of multiple random fault resilience, and proposes a node weight calculation method, to comprehensively evaluate the overall resilience of ADN. In a case study, IEEE 33 bus model is taken as an example medium voltage distribution network, and Monte Carlo simulation is used to simulate random faults in that system. From the results, the proposed method can reflect the improvement of resilience after the implementation of different countermeasures, thus the effectiveness of this method can be verified.
