本文分析了在电力系统实时监控应用中，为支持分布式能源数字孪生（DTs）的运行，对实时数据源报告率的要求。由于缺乏足够的测量和通信基础设施，配电网络的可见性目前受到限制。随着分布式配电系统的快速增长，提高配电网络的可见性以保证持续满足系统运行的关键约束变得越来越重要。DTs是物理系统的虚拟复制品，具有一定的实时测量数据，可以用来准确地表示物理实体的实时动态。因此，DTs的特性可以应用于增加网络的可见性，并可能支持实时决策。本文研究了数据报告率对DT精度的影响，并在此基础上提出了一种方法，可用于量化数据报告率的最低要求，以充分支持DT操作，这为指定测量设备和通信网络提供了有价值的学习，以实现基于DT的解决方案。
This paper analyzes the requirements for the reporting rate of the live data source to support the operation of Digital Twins (DTs) of Distributed Energy Resources (DERs) for real-time power systems monitoring applications. The visibility of distribution networks is currently limited due to the lack of sufficient measurement and communication infrastructures. With the rapid increase of DERs, it becomes increasingly important to improve the visibility of the distribution networks to ensure the critical system operating constrains are continuously met. DTs are virtual replicas of physical systems, and with certain live measurement data, they can be used to accurately represent the real-time dynamics of the physical entities. The features of DTs could therefore be applied to increase the visibility of network and potentially support real-time decisions making. This paper presents the investigation of the impact of data reporting rate on DT accuracy, based on which, the paper presents a method that could be used to quantify the minimum requirements for data reporting rate to adequately support the DT operation, which provides valuable learning for specifying measurement devices and communication networks to enable DTs-based solutions.
