“…It is concluded that event notification middleware architectures for SMGs have various challenges: 1. Real-time distributed pub/sub protocols which enable P2P communications [25] [26]: P2P communication architecture provides a more reliability and suitable environment for distributed devices as it permits selfdiscovery of new nodes/devices and self-organization. Due to this, the dynamic participation of the nodes/devices in the network is allowed and it is especially important for microgrids, in which a large number of devices (electric vehicles, loads, etc.)…”

Microgrids are moving towards large-scale smart distributed networks which demand an efficient and reliable communication infrastructure to manage, control and monitor energy resources. With regard to this, publisher/subscriber event-based middleware has become relevant for large-scale distributed time applications because it allows decouple time and space between senders and receivers. Particularly the content publish/subscribe systems over structured peer-to-peer (P2P) networks has emerged to enhance scalability and dynamism of notification middleware systems. However, this type of systems use multicast routing schemes that still generate much network traffic and as a consequence an overload of the communication channel is produced. This results in inefficient network utilization and rapid depletion of network resources leading to unreliable operations, degradation of system performance and even instability of the microgrid. In this paper, a new contentbased publish/subscribe notification middleware over structured P2P systems is proposed, such that smart microgrid communication requirements are met. This proposed system organizes the publications and subscriptions in a one dimensional representation using the Hilbert space filling curve. Through this representation, an innovative routing and matching algorithms are developed. Experimental results demonstrate that the proposed publisher/subscribe system significantly enhance efficiency of the system, network performance and the use of computational resources.

“…The connectivity between them is not carried out by creating virtual links (overlays), which cause lack of self-discovery and self-healing capabilities [34]. To overcome these limitations, [25], [26] propose a Data Distribution Service (DDS) middleware. This kind of middleware uses Pub/Sub communications over P2P networks.…”

“…It is actually a controllable breaker, which gives the important advantage to the microgrid of separating itself from the power system whenever it is needed. This breaker actually monitors and executes requests for an islanding or resynchronization of the microgrid [13]. The correct control of the PCC allows the smooth and seamless transition between the grid-connected and the islanded mode.…”

During the last decade, microgrids are attracting a significant attention due to their numerous advantages. Amongst them, the most important one is their ability to operate either in grid-connected or in islanded (autonomous) mode. However, the transition between the two modes can be challenging in terms of maintaining the stability and integrity of the microgrid. In this paper, an optimization-based islanding methodology is developed to ensure a timely and smooth transition from the grid-connected to the islanded mode. This is achieved through shedding loads, by defining the generation level of the photovoltaics (energy spill) and by regulating the charging/discharging rate of batteries. A resynchronization method is also presented along with the requirements that need to be satisfied for the smooth reconnection of the microgrid back to the main grid. The effectiveness of the proposed approach is demonstrated through simulation results for the events of surplus energy production, and excess energy demand of the microgrid.

“…Reference presents a generic, standards‐based system that is able to fully automatically deploy IoT applications based on the TOSCA standard, the standardized message queuing telemetry transport (MQTT) messaging protocol, the Mosquitto message broker and the runtime environment OpenTOSCA. Reference proposed a publish–subscribe protocol‐based communication schema for microgrids. Reference introduces the MQTT publish–subscribe protocol as a suitable transport mechanism to support next‐generation distributed energy resource (DER) applications in smart grid.…”

As a typical cyber physical system (CPS), a smart grid should facilitate more robust integration and interoperability of information models and subsystems so that the performance of the physical system can be optimized. However, the intrinsic complexity and heterogeneity of CPS are two of the biggest obstacles to interoperation and interconnection among various information models and subsystems. In order to address the dilemma, this paper proposed a systematic, data-centric system design approach comprehensively including data-oriented system architecture, data resources abstraction and data-driven mechanisms. To be specific, the autonomous decentralized system (ADS) theory is introduced to establish the data-centric system architecture. A MQTT/MQTT-SN-based communication protocol, which supports not only IP-based devices but also non-IP devices, is proposed to meet the requirement of publish-subscribe mechanism of the ADS-based system architecture. A data-centric meta-interface is proposed to formalize the data resources abstraction. A Lebesgue sampling-based data exchange mechanism, which is proven tractable but effective, is proposed to realize the data-driven mechanism. As user energy management system (UEMS) is an integral part of smart grid, a realistic UEMS for heating project is considered a typical case to study the performance of the proposed data-centric system. This paper is one of the first few papers that systematically propose a systematic data-centric system design approach for a smart grid, which is supported by aspects of system architecture, communication protocol and data exchange mechanism.
