“…In addition, if the main control and communication system can accommodate more MGs, expanding and attaching them to the design above is quite simple. However, this architecture fails to ensure the reliability of the network or the main grid since there is only one feeder from the grid with the MGs, which will be stressed or overloaded on some occasions [32,34,35]. Increasing the overall system's reliability and shared power for the architecture above can be achieved by connecting each MG directly to its neighbors, forming a daisy-chain topology, which can also be called parallel MGs on a single feeder, as shown in Figure 3b.…”

Networked microgrids (NMGs) are developing as a viable approach for integrating an expanding number of distributed energy resources (DERs) while improving energy system performance. NMGs, as compared to typical power systems, are constructed of many linked microgrids that can function independently or as part of a more extensive network. This allows NMGs to be more flexible, dependable, and efficient. The present study comprehensively investigates architecture, communication, and cybersecurity issues in NMGs. This comprehensive study examines various aspects related to networked microgrids (NMGs). It explores the architecture of NMGs, including control techniques, protection, standards, and the challenges associated with their adoption. Additionally, it investigates communication in NMGs, focusing on the technologies, protocols, and the impact of communication on the functioning of these systems. Furthermore, this study addresses cybersecurity challenges specific to NMGs, such as diverse cyberattack types, detection and mitigation strategies, and the importance of awareness training. The findings of this study offer valuable insights for NMG researchers and practitioners, emphasizing critical aspects that must be considered to ensure the safe and efficient operation of these systems.

This paper presents an energy management strategy for hybrid renewable micro-grid system. The optimal operation of a hybrid renewable micro-grid system necessitates a sophisticated energy management strategy that can orchestrate the intricate interplay of diverse energy sources and loads while considering factors such as weather variability, demand fluctuations, and equipment limitations. This strategy is crucial in achieving the overarching goals of such systems: maximizing renewable energy utilization, minimizing greenhouse gas emissions, enhancing energy independence, and ensuring grid resilience. Furthermore, the intermittent and weather-dependent nature of renewable sources necessitates a predictive approach that anticipates energy availability and adapts the operation of the system accordingly. The aim of this study was to develop an energy management system for a hybrid renewable micro-grid system to optimize the deployment of renewable energy resources and increase their integration in the power system. Therefore, the main objective of this proposed work was to develop an energy management strategy that controls the flow of energy between the hybrid micro-grid system and the load connected directly as well as the load connected to the utility grid using MATLAB/Simulink software. The second objective was to control the charging and discharging of the battery energy storage. The results show that the developed algorithm was able to control the energy flow between the hybrid micro-grid system and the variable AC load directly connected as well as connected to the utility grid and also to ensure a proper relation between the charging / discharging rate of the battery energy storage system based on their operating conditions and finally, it ensured the SOC of battery remained in the admissible limits (between 20% and 100%).

In the current landscape, Smart Grids (SGs) grapple with critical challenges, notably their reliance on centralized networks and the absence of microgrid system integration. The concept of a multi-microgrid solution emerges as an approach that interconnects and orchestrates multiple microgrids, enhancing the electrical system’s resilience, scalability, and capacity to integrate distributed renewable energy sources, enabling Demand-Side Management (DSM) for a more efficient and secure network. This study introduces a novel hybrid Internet of Things (IoT) architecture employing LoRaWAN and LoRaMESH to address these challenges. This approach, operating within a decentralized multi-microgrid framework, reduces message transmission time by over 50%, demonstrating its efficacy and relevance while streamlining communication between Smart Meters (SMs) and the Electric Power Company (EPC), ultimately fostering the adoption of DSM services by consumers and representing a transformative solution for the future of Sgs.
