“…For short-term storage, aiming at covering the frequent instantaneous power peaks, batteries are usually used. Typically, commercially-available battery types are used, which have well-proven capabilities and come at a low cost, such as lead-acid and lithium-ion batteries [27,29,36]. Redox flow batteries are suitable for long-term storage; however, they have a lower round-trip efficiency and significantly lower power density than lithium-ion batteries [37,38].…”

“…Another important advantage of hydrogen storage is the very high energy density of hydrogen, which is highly desirable in vehicular applications, and in general in applications where space restrictions are unavoidable [14]. The most practical hydrogen storage technology is compressed hydrogen, due to its technological maturity and low capital cost [29]. However, other hydrogen storage technologies have emerged in recent years that do not require high pressurization, such as metal hydrides [39,40].…”

Hybrid photovoltaic–regenerative hydrogen fuel cell (PV-RHFC) microgrid systems are considered to have a high future potential in the effort to increase the renewable energy share in the form of solar PV technology with hydrogen generation, storage, and reutilization. The current study provides a comprehensive review of the recent research progress of hybrid PV-RHFC microgrid systems to extract conclusions on their characteristics and future prospects. The different components that can be integrated (PV modules, electrolyzer and fuel cell stacks, energy storage units, power electronics, and controllers) are analyzed in terms of available technology options. The main modeling and optimization methods, and control strategies are discussed. Additionally, various application options are provided, which differentiate in terms of scale, purpose, and further integration with other power generating and energy storage technologies. Finally, critical analysis and discussion of hybrid PV-RHFC microgrid systems were conducted based on their current status. Overall, the commercialization of hybrid PV-RHFC microgrid systems requires a significant drop in the RHFC subsystem capital cost. In addition, it will be necessary to produce complete hybrid PV-RHFC microgrid systems with integrated energy management control capabilities to avoid operational issues and ensure flexibility and reliability of the energy flow in relation to supply, storage, and demand.

“…To estimate the losses of the parallel inverters system, three serial equivalent voltage sources V tabcn and current source I P at the input dc-link are employed. During the balanced conditions, sum of the load side currents is zero, as in (1). Likewise, sum of the inverter output line currents is zero at the PCC, as given by (2).…”

Microgrids are integral to power grids; they enhance grid reliability by integrating distributed generators (DGs) to fulfill the local load requirements, lowering energy generation costs, and providing eco‐friendly energy resources to reduce carbon emissions. Despite their benefits, new capabilities also introduce protection‐related complexities, including bidirectional power flow, varying fault currents, false tripping, relay reach limitations, coordination issues, and the requirement for proper grounding. This article offers a detailed review of protection issues in AC, DC, and hybrid AC–DC microgrids, investigating existing approaches to address these issues. Furthermore, the constraints and hurdles associated with these approaches and the future trends and intelligent approaches required to develop a reliable and efficient protection strategy are also identified in this article.This article is categorized under: Energy and Power Systems > Microgrids Energy and Power Systems > Distributed Generation
