“…Over the years, cyber-physical systems (CPSs) have attracted considerable attention given their wide applications in grids, intelligent robot networks, embedded systems, and other fields. A typical CPS is capable of real-sensing, dynamic control, and information services [1][2][3]. Smart cyber systems provide better monitoring, transferring, and controlling functions for the substation, but produce a trade-off, as the substation will experience more cyber-attacks.…”

With the increasing interaction between physical devices and communication components, the substation based on the IEC 61850 standard is a type of cyber–physical system. This paper proposes a reliability analysis method for substations with a cyber–physical interface matrix (CPIM). This method calculates the influences from both the physical device failures and the communication devices failures. Two indices, Probability of Load Curtailments and Expected Demand Not Supplied, are used in the reliability analysis. Given the simplified model of the practical substation based on the Chinese IEC 61850 standard, the results show that the substation system had a potential risk of cascading failure under the cyber–physical fusion trend, as the failure in cyber layer would increase the power loss of the whole system. The changing magnitude of Expected Demand Not Supplied increased significantly with increasing transmission delay rate of the process bus.

“…Considering the popularity of IEC 61850 [22] and its capability to exchange high volume of data in a standardized and interoperable manner, researchers and engineers started thinking about using it beyond SAS implementations. Several extension publications, such as 7-420 for distributed energy resources (DERs), IEC 61850 evolved from a SAS standard into a communication standard that covers entire power utility automation.…”

Smart grid is the nexus of advanced Information and Communication Technologies (ICT) and legacy power systems. With increasing awareness on vulnerabilities of smart grids to cyber-attacks, cybersecurity is becoming a prime concern. Earlier, it was assumed that power system communication protocols are very specialized and different, so the "security by obscurity" approach would be sufficient. However, with the standardization of communication protocols for power utilities and emergence of power market, this approach is no longer valid. IEC 62351 standard has been published to provide security recommendations for different power system communication protocols including IEC 61850. IEC 61850 is emerging as the most promising and popular power system communication standard. Therefore, in this paper, a detail analysis of security threats, possible attacks and security requirements for IEC 61850 communication is presented. Building on this, the security considerations presented in IEC 62351 for securing different IEC 61850 messages such as Generic Object-Oriented Substation Events (GOOSE), Sampled Values (SV), Routable-GOOSE (R-GOOSE), Routable-SV (R-SV) and Manufacturing Message Specification (MMS) messages have been presented in great detail.

“…This system also allows the supervision, control a series of devices or variables [31]. On the other hand, the increase in renewable energy generation and co-generation require the application of technologies in such a way that their management and protection is possible [32]. This impact on electrical networks is currently manifested, both in the transmission and distribution.…”

The entire electrical system is changing at an abrupt speed since its beginning. With the rapid advance of renewable energies (which are constantly subject to fluctuations), the electricity generation is distributed to countless locations. The traditional model of the unidirectional flow of electricity is leaning towards multidirectional flows. This situation needs significant changes in the transport infrastructure of the electrical power system and mode of operation. Technological advancements are making a smarter and more organized management system of electricity supply and demand. This development needs to incorporate modern communication, monitoring, and control capabilities, along with the intelligent transport, generation, and storage value chain. Digital substations integrate thousands of sensors by providing greater comfort, self-reliance, availability, and safety while at the same time reducing costs, risks, and environmental damage. Conventional power system lacks digital communication, remote monitoring & control, and consumer participation. Fiber-optic cabling in digital substations will attain not only real-time data transmission but also remote maintenance. The comparison between conventional and digital substations has also been presented in this work along with latest trends in smart protection. Electronic protection and control devices based on a microprocessor, communicating with cloud servers, will enhance the flexibility to control and monitor the digital substations. A significant amount of data generated by components in the electrical substations will allow greater sophistication of the monitoring, diagnostic, protection and optimization capabilities of the facilities. The goal for the review of said advancements is to have a smart electrical system with greater efficiency and better user experience.
