“…Regarding the measured triggering time of the PIOC, the given setup is significantly shorter than this time. In [6,21], the transmission times were examined in more detail using the SDN infrastructure. In particular, [6] shows that the transmission times can be well maintained within the framework of the co-simulations with direct coupling.…”

“…These vary greatly depending on the arc extinguishing method (oil, FS6, vacuum, and air) and are not modeled and taken into account in the Hypersim model. Furthermore, the impact of network infrastructure, particularly Ethernet, on these processes has been modeled and discussed in detail in [21]. Table 1 shows the measured total fault clearance times.…”

This paper presents an investigation into the virtualization of substation protection IED functions using a sophisticated co-simulation environment that integrates virtual intelligent electronic devices (vIEDs) with a real-time power grid simulation. Anchored by the IEC 61850 protocol, this study constructs a virtualized IED framework, emphasizing the encapsulation of protection schemes using the example of different types of overcurrent protection within a containerized vIED. Using open-source software, this study aims to replicate the communication and functional aspects of physical IEDs. This study uses a co-simulation environment that couples virtualized network components with a real-time power grid simulation to validate the vIEDs against real substation hardware. Simulation results from induced short-circuit events confirm the operational congruence of the vIEDs with their physical counterparts, demonstrating their potential to serve as cost-effective and adaptable testbeds for substation automation. This paper concludes that virtualized IEDs represent a cost-effective, flexible alternative for substation automation testing, with future research directed towards increasing the functional complexity and real-world applicability of these virtual systems.

“…The safety of substations can be divided into three categories based on the main dimensions: equipment safety, network safety, and personnel safety. At present, the research work on substation security mainly focuses on equipment security and network security [1][2][3][4]. There is relatively little research on the safety of substation operators.…”

This paper proposes a box type substation operation safety management and control system based on GIM modeling technology and UWB positioning technology to address the current challenges of personnel and vehicle control, single control methods, difficult information exchange, and blind spots in on-site substation operations. This system integrates safety control measures throughout the entire operation process of the substation before, during, and after operation, achieving closed-loop control of operation safety. Firstly, laser point cloud and power system GIM technology are used for three-dimensional modeling of substation environment and equipment. Then, UWB positioning technology is used for indoor positioning. Combined with various business systems such as substation work tickets and SCADA, the qualification review of station personnel and vehicles before substation operation is achieved, real-time monitoring of personnel status and movement trajectory during operation, and real-time monitoring of on-site environment after operation are achieved. The system has been deployed and applied to a 35kV box type substation in Guizhou, and through a period of actual operation, it has effectively controlled the operation site.

The digitalization of substations leads to a high degree of automation, which is referred to as Digital Substations with the use of the IEC 61850. An increase in cybersecurity is necessary, and technically enabled by detection and incident response systems – security-by-design is currently often secondary. The next transformation step of substations is introduced and outlined in this paper as a cyber-resilient digital substation. Based on a state-of-the-art description, this paper presents a definition of cyber resilience for digital substations as a basis for the introduced cyber resilience monitor. The monitor acts as a central instance for recording, assessing and responding to security threats and incidents. Furthermore, the requirements for the system structure of the cyber-resilient digital substation are shown and underpinned with current research approaches.
