“…MQTT is more successful in terms of energy efficiency. In another study comparing CoAP and MQTT protocol in transporting the same data [19], CoAP protocol was stated to be more efficient. In a study conducted in an environment with high network traffic, the MQTT protocol was reported to be more successful than CoAP, with a higher bandwith and lower latency [20].…”

One of the important factors affecting communication performance in the Internet of Things is the messaging protocol. MQTT, XMPP and AMQP are centralized application protocols that communicate through the server. DDS and CoAP are application protocols that can communicate directly, especially in real-time applications. As the Internet of Things is becoming more widespread and usage scenarios have different requirements, new approaches to data communication are required. In this study, a UDP based hybrid application layer protocol has been designed which can communicate both directly and through central server. In addition, operating logic and packet structure of the developed hybrid protocol is examined.

“…While these proposals feature widely used technologies (HTTP and XMPP), they incur a high communication overhead due to the text-based nature of HTTP and the complexity and overhead of exchanging presence information within eXtensible Messaging and Presence Protocol (XMPP), as well as it being based on the rather verbose eXtensible Markup Langage (XML). Shin et al propose in [16] the first approach to use a protocol specifically created for IoT systems, CoAP. However, the authors map just a reduced set of functions and they do not follow a RESTful approach, as they use different resources for PUT and GET requests.…”

Electrical substations are crucial elements of Smart Grids where they are mainly responsible for voltage transformations. However, due to the integration of distributed energy resources in the grid, substations now have to provide additional grid management capabilities which in turn require supervision and automation solutions for large low-voltage grids. A recurring challenge in such deployments are siloed systems that are due to non-interoperable communication protocols across substations: although most substations' communication is based on the International Electrotechnical Commission (IEC) 61850 standard, deployed legacy protocols lag behind modern communication technologies in terms of performance, hindering the full transition to lightweight protocols. This paper demonstrates that IEC 61850 can be fully mapped to the Constrained Application Protocol (CoAP) in combination with the Concise Binary Object Representation (CBOR) format while improving system performance compared to existing alternatives (e.g. WS-SOAP and HTTP). On average, CoAP+CBOR needs 44% and 18% of the message size and 71% and 85% of the time compared to systems based on HTTP and WS-* Web Services, respectively-this is especially relevant for resource-constrained devices and networks in electrical grids. In addition, CoAP is based on the Representational State Transfer (REST) architectural style, which supports system integration and interoperability through uniform identification and interaction. This approach fosters the standard-compliant integration of legacy platforms with modern substations as well as current IoT systems in neighboring domains such as building management and infrastructure automation systems.

Real-Time Analysis of Time-Critical Messages in IEC 61850 Electrical Substation Communication Systems

et al. 2019

IEC 61850 is a standard for the design and operation of electrical Substation Automation Systems (SAS) that defines how data may be transferred among Intelligent Electronic Devices (IEDs). The defined data models can be mapped into application protocols, such as SV or GOOSE, which may run upon high speed Ethernet LANs bridged by IEEE 802.1Q compliant switches. The communication system must cope with the timing requirements associated to protective relaying strategies. Given the time constrained nature of SAS applications, a thorough analysis of its timing behavior is required. In this paper, we propose an analytical model for the timing assessment of SV and GOOSE message exchanges in an IEC 61850 process bus. The proposed model allows the communication timing assessment, by analyzing the response time of each message stream of the SAS. This feature is an advantage for the expansion of the SAS, as it allows the evaluation at design time of the maximum number of IEDs that can be supported by the underlying communication system. The results from the proposed analytical model were validated for a typical IEC 61850 communication scenario, both through simulation and through an experimental assessment with IEC 61850 compliant equipment.
