近年来，自然灾害的数量和严重程度不断增加，这就要求对电力系统，特别是微电网系统进行抗灾能力评估和增强。应急配电电源对提高微网在紧急环境下的抗停电能力具有很大的潜力。研究了自然灾害下微电网系统的恢复力评估问题，即在系统节点上预先配置应急电源，并在系统发生故障后重新配置应急电源。提出了一种新的弹性度量指标和一种有效的近似计算方法，用于焦点问题的弹性评估。针对自然灾害下微网系统的应急恢复问题，提出了一种新的应急电源预置策略和重构策略。此外，弹性评估框架提供了解决问题。在改进的IEEE 30节点系统和改进的IEEE 118节点系统上进行的大量实验结果证实了弹性评估方法的有效性和所提出的恢复策略的优越性。
Recently, increasing the number and severity of the natural hazards requires the resilience assessment and enhancement of the power system, especially the microgrid system. The emergency distribution generations have great potential to enhance the resilience of microgrid against blackouts under the emergency environment. This paper investigates the resilience assessment of the microgrid system under natural hazard, where emergency distribution generations are firstly pre-positioned on system nodes and then reconfigured after system damage occurs. A new resilience metric index and an efficient approximation computation method are provided for the resilience assessment of the focused problem. A new pre-position strategy and a new reconfiguration strategy on emergency distribution generations are proposed for the microgrid system emergency restoration under natural hazard. Also, a framework of resilience assessment is provided for problem-solving. The results of extensive experiments on the modified IEEE 30-Bus system and modified IEEE 118-Bus system confirm the effectiveness of the resilience assessment methodology and the superiority of proposed restoration strategies.
