“…The messages parameters are taken from the automation and automotive application domains, respectively, and the total bandwidth is set to 100 Mbps. The industrial scenario is setup with flow periods in the order of few milliseconds that are typical of the microgrid automation applications (Rinaldi et al 2015), while the topology is chosen to consider the maximum hops that the standard guarantees (i.e., 7 hops). Moreover, the traffic parameters in the automotive case study are inspired from the architecture designed by BMW group .…”

The IEEE Audio Video Bridging (AVB) technology is nowadays under consideration in several automation domains, such as, automotive, avionics, and industrial communications. AVB offers several benefits, such as open specifications, the existence of multiple providers of electronic components, and the real-time support, as AVB provides bounded latency to real-time traffic classes. In addition to the above mentioned properties, in the automotive domain, comparing with the existing in-vehicle networks, AVB offers significant advantages in terms of high bandwidth, significant reduction of cabling costs, thickness and weight, while meeting the challenging EMC/EMI requirements. Recently, an improvement of the AVB protocol, called the AVB ST, was proposed in the literature, which allows for supporting scheduled traffic, i.e., a class of time-sensitive traffic that requires time-driven transmission and low latency. In this paper, we present a schedulability analysis for the real-time traffic crossing through the AVB ST network. In addition, we formally prove that, if the bandwidth in the network is allocated according to the AVB standard, the schedulability test based on response time analysis will fail for most cases even if, in reality, these cases are schedulable. In order to provide guarantees based on analysis test a bandwidth over-reservation is required. In this paper, we propose a solution to obtain a minimized bandwidth over-reservation. To the best of our knowledge, this is the first attempt to formally spot the limitation and to propose a solution for overcoming it. The proposed analysis is applied to both the AVB standard and the AVB ST. The analysis results are compared with the results of several simulative assessments, obtained using OMNeT++, on both automotive and industrial case studies. Real-Time Syst (2017) 53:526-577 527 between the results of the analysis and the simulation ones shows the effectiveness of the analysis proposed in this work.

“…Digital substations that rely on fully IP-based communication offer advantages in terms of system integration, system operation, and IT security [4]. In addition to the process-related advantages, digitalized processes enable investigations and analyses that generate additional values in operation that go beyond classic monitoring [5]. Furthermore, transformer stations in low voltage grids are increasingly equipped with integrated measurement devices and provide data for local grid management and for the overlaying control and monitoring processes.…”

This paper presents a hierarchical Digital Twin architecture and implementation that uses real-time simulation to emulate the physical grid and support grid planning and operation. With the demand for detailed grid information for automated grid operations and the ongoing transformation of energy systems, the Digital Twin can extend data acquisition by establishing a reliable real-time simulation. The system uses observer algorithms to process model information about the voltage dependencies of grid nodes, providing information about the dynamic behavior of the grid. The architecture implements multiple layers of data monitoring, processing, and simulation to create node-specific Digital Twins that are integrated into a real-time Hardware-in-the-Loop setup. The paper includes a simulation study that validates the accuracy of the Digital Twin, in terms of steady-state conditions, dynamic behavior, and required processing time. The results show that the proposed architecture can replicate the physical grid with high accuracy and corresponding dynamic behavior.

“…There is a growing trend in industrial automation to deploy wireless communication in a hybrid network as an enabler for certain control applications [52][53][54][55][56]. To realize these applications, Ethernet-based wired sub-network has to be interconnected with a wireless segment at the data-link or the application layer [57][58][59].…”

Undertaking doctoral study has been a truly life-changing experience for me and it would never have been possible to take this work to completion without the guidance and support that I received from many people. Firstly, I would like to express my sincere appreciation and respect to my supervisor, Professor Xie Lihua, for his professional guidance and valuable suggestions throughout my time as his student. I could not imagine having had a better advisor and mentor for my research work. I owe the deepest gratitude to my family for their encouragement and love. My wife and my parents have been extremely supportive of me throughout the entire study and have made countless sacrifices to help me get to this point. I also thank the staff and students in the Internet of Things Laboratory of Nanyang Technological University for their help.
