“…IEC 61850 is the international standard for communications in substations which defines a universal data model to facilitate the interoperability of different equipment and devices [30]. In this work, the IEC 61850-7-420 standard defined the information models which were used in the exchange of information with distributed energy resources (DER) and distribution automation (DA).…”

With the rapidly growing energy consumption and the rising number of prosumers, next-generation energy management systems are facing significant impacts by peer-to-peer (P2P) energy trading, which will enable prosumers to sell and purchase energy locally. Until now, the large-scale deployment of P2P energy trading has still posed many technical challenges for both physical and virtual layers. Although the communication infrastructure represents the cornerstone to enabling real-time monitoring and control, less attention has been given to the performance of different communication technologies to support P2P implementations. This work investigates the scalability and performance of the communication infrastructure that supports P2P energy trading on a community microgrid. Five levels make up the developed P2P architecture: the power grid, communication network, cloud management, blockchain, and application. Based on the IEC 61850 standard, we developed a communication network model for a smart consumer that comprised renewable energy sources and energy storage devices. Two different scenarios were investigated: a home area network for a smart prosumer and a neighborhood area network for a community-based P2P architecture. Through simulations, the suggested network models were assessed for their channel bandwidth and end-to-end latency utilizing different communication technologies.

“…The manufacturers established proprietary communication protocols for their IEDs, which led to challenges in interoperability between devices. This resulted in the development of IEC61850 to standardize data models in electrical systems equipment and provided operational specifications and engineering standards for required applications in electrical networks so as to mitigate the interoperability challenge amongst devices [67,71]. In traditional substations, the communication signal would travel a long distance from the substation to the control room, which resulted in a high frequency of failures, expensive maintenance, and operational costs [71].…”

“…Upon receiving the data from the bay level, human operators can execute various tasks and configurations of SCADAs and Human Machine Interfaces (HMIs). It also connects the substation to a remote-controlled room from kilometers away, allowing a central operator or utility to manually modify the state of equipment and monitor the substation's activities [67].…”

“…The connection of these different levels is through two busses as per IEC61850, which are the process bus and the station bus, as depicted in Figure 4 below. This is where the interconnection of the process level interconnects with the bay level and the bay level connects with the station level, where different network protocols are supported with varying communication needs [67]. Internet protocols are slow during transient in real-time systems, so the IEC 61850 employs several protocols to attain quicker responses.…”

Power systems have been going through a barrage of transformations due to the recent developments in the field, such as deregulation and restructuring of the electric power supply chain, the proliferation of distributed generation (DG), and advancements in information and communications technologies. These have significantly impacted the approach to the planning, design, and operation of active distribution networks or systems. Due to this constant change, the system has become more complex to plan, maintain, and control. In this paper, the benefits and challenges of active distribution systems relative to traditional passive and active distribution systems are evaluated and investigated while the management and operational characteristics of demand-side resources in active distribution systems (ADS) are studied. In a typical ADS, there exist several vulnerabilities and threats that eventually pose a challenge in the control and automation of substations. These vulnerabilities and threats are reviewed, and potential mitigation measures are suggested. Also in this paper, the communication technologies and their implementation in terms of control and automation capabilities in active distribution networks are also studied. From this work, it is concluded that communication technologies play an integral role in the realization of more active distribution networks and that the Internet of Energy (IoE) is a major player in ADS in the reduction of faults due to human error, fast responses, and improving the stability of power supply. Cyber threats are also and will still be a continuous challenge in smart metering technologies and in substation automation systems (SAS), which will require frequent evaluation and mitigation measures so as not to prevent the power supply system from collapsing.
