Abstract: Smart grid cyber-physical system (CPS) exploits various physical components to provide better knowledge and delicate control of the power grid, while the huge data volume is transmitted via the integration of advanced communication technologies. To provide better services for the applications in the smart grid CPS, the communication network has to consider the aspects of both improving the system throughput and meeting the real-time requirement. In order to address this issue, a new communication strategy is proposed in this study. The strategy is based on the time performance features of different smart grid CPS applications, which also exploits both temporal and spatial available spectrum resources for transmitting via spectrum sharing techniques. Moreover, the performance has been verified by a case study based on IEEE 14-bus power system. An important real-time application, namely real-time voltage stability enhancement, has been investigated in the case study. Results show that the proposed communication strategy is able to improve the throughput of the smart grid CPS and the time performance of time sensitive applications.

“…Secure communications rely on a series of protocols and standards are categorized broadly into control versus communication, where the protocols on Information Technologies (IT), Information and Communication Technologies (ICT) and Operational Technologies (OT) belong to the control scheme. Third, smart computation techniques such as artificial intelligence (AI), deep learning and edge computing lead to advanced implementations of the CPS [39].…”

“…The service placement and workload scheduling decisions were assisted by means of DQN technology [28]. From the perspective of communication technology, Minglei et al proposed a new communication strategy, which not only improves the real-time performance of the smart grid CPS system but also increases the system throughput [29]. Wang et al proposed the heterogeneous brain-storming (HBS) method for object recognition tasks in real-world Internet of Things (IoT) scenarios, which enables flexible bidirectional federated learning of heterogeneous models trained on distributed datasets with a new "brain-storming" mechanism and optimizable temperature parameters.…”
