论文摘要
相互联系的复杂系统通常由于内部不确定性和外部负面影响,例如由严酷的操作环境或区域自然灾害事件造成的外部负面影响。为了在内部和外部挑战下保持相互联系的网络系统的运行,通过更好的设计和提高故障恢复能力来提高系统的可靠性,从而进行了弹性研究设计。至于增强设计,由于现代系统的规模越来越大,并且存在复杂的潜在物理限制,因此出现了设计强大系统的挑战。为了应对这些挑战并有效地设计弹性系统,本研究提出了一种使用图形学习算法的生成设计方法。生成设计框架包含性能估计器和候选设计生成器。发电机可以从现有系统中明智地挖掘出良好的属性,并输出符合预定义绩效标准的新设计。尽管估计器可以有效地预测生成的设计的性能,从而在快速的迭代学习过程中。基于IEEE数据集的电源系统的案例研究结果说明了所提出的方法设计弹性互连系统的适用性。
Interconnected complex systems usually undergo disruptions due to internal uncertainties and external negative impacts such as those caused by harsh operating environments or regional natural disaster events. To maintain the operation of interconnected network systems under both internal and external challenges, design for resilience research has been conducted from both enhancing the reliability of the system through better designs and improving the failure recovery capabilities. As for enhancing the designs, challenges have arisen for designing a robust system due to the increasing scale of modern systems and the complicated underlying physical constraints. To tackle these challenges and design a resilient system efficiently, this study presents a generative design method that utilizes graph learning algorithms. The generative design framework contains a performance estimator and a candidate design generator. The generator can intelligently mine good properties from existing systems and output new designs that meet predefined performance criteria. While the estimator can efficiently predict the performance of the generated design for a fast iterative learning process. Case studies results based on power systems from the IEEE dataset have illustrated the applicability of the proposed method for designing resilient interconnected systems.
