论文摘要
网络拓扑识别(TI)是分布式能源资源管理系统(DERMS)组织和运营广泛分布式能源(DERS)的重要功能。在本文中,部署了判别分析(DA)来开发仅依赖于真皮可用的测量值的网络TI函数。提出的方法能够识别网络交换配置以及保护设备的状态。以后,为了提高与通信渠道中断的TI弹性,提出了一种二次编程优化方法来恢复缺失的信号。通过将主题的数据恢复方法和贝叶斯定理部署在一起,随后开发了一个基准,以识别异常测量。该基准可以使TI功能具有针对网络攻击的弹性。这种方法的计算负担较低,可以快速轨道,可以应用于实时应用程序。进行灵敏度分析以评估不同测量值的贡献以及系统负载类型和加载水平对拟议方法的性能的影响。
Network topology identification (TI) is an essential function for distributed energy resources management systems (DERMS) to organize and operate widespread distributed energy resources (DERs). In this paper, discriminant analysis (DA) is deployed to develop a network TI function that relies only on the measurements available to DERMS. The propounded method is able to identify the network switching configuration, as well as the status of protective devices. Following, to improve the TI resiliency against the interruption of communication channels, a quadratic programming optimization approach is proposed to recover the missing signals. By deploying the propounded data recovery approach and Bayes' theorem together, a benchmark is developed afterward to identify anomalous measurements. This benchmark can make the TI function resilient against cyber-attacks. Having a low computational burden, this approach is fast-track and can be applied in real-time applications. Sensitivity analysis is performed to assess the contribution of different measurements and the impact of the system load type and loading level on the performance of the proposed approach.
