论文摘要
关键的能源基础设施越来越依赖高级感应和控制技术，以有效，最佳利用灵活的能源资源。需要算法程序以确保该系统被设计为具有弹性的网络物理对抗事件。本文提供了一个强大的优化框架，以量化系统可以在不违反预指定的弹性指标的情况下适应的对抗扰动范围。可以通过基于优化的方法构建一组可以通过可用灵活性来减轻的对抗事件的内部附属物。在一个岛的微电网示例中说明了所提出的算法：一种具有分布式能量的IEEE 123节点馈线。进行仿真以验证从构造的对抗集中采样的任何事件以不同级别的可用柔韧性（能量储备）来满足弹性指标。
Critical energy infrastructures are increasingly relying on advanced sensing and control technologies for efficient and optimal utilization of flexible energy resources. Algorithmic procedures are needed to ensure that such systems are designed to be resilient to a wide range of cyber-physical adversarial events. This paper provides a robust optimization framework to quantify the range of adversarial perturbations that a system can accommodate without violating pre-specified resiliency metrics. An inner-approximation of the set of adversarial events which can be mitigated by the available flexibility is constructed using an optimization based approach. The proposed algorithm is illustrated on an islanded microgrid example: a modified IEEE 123-node feeder with distributed energy resources. Simulations are carried out to validate that the resiliency metrics are met for any event sampled from the constructed adversarial set for varying levels of available flexibility (energy reserves).
