“…Furthermore, EMSs, in case of interruption of the primary power supply, should be able to start the backup power supply by starting the FC which, coupled to an electrolyzer, produces the fuel (for example, hydrogen (H 2 )) on demand [29][30][31]. Now, many authors are busily engaged in the design and validation of EMSs for DC-MGs with high reliability and performance.…”

Recently, the implementation of software/hardware systems based on advanced artificial intelligence techniques for continuous monitoring of the electrical parameters of intelligent networks aimed at managing and controlling energy consumption has been of great interest. The contribution of this paper, starting from a recently studied DC-MG, fits into this context by proposing an intuitionistic fuzzy Takagi–Sugeno approach optimized for the energy management of isolated direct current microgrid systems consisting of a photovoltaic and a wind source. Furthermore, a lead-acid battery guarantees the stability of the DC bus while a hydrogen cell ensures the reliability of the system by avoiding blackout conditions and increasing interaction with the loads. The fuzzy rule bank, initially built using the expert’s knowledge, is optimized with the aforementioned procedure, maximizing external energy and minimizing consumption. The complete scheme, modeled using MatLab/Simulink, highlighted performance comparable to fuzzy Takagi–Sugeno systems optimized using a hybrid approach based on particle swarm optimization (to structure the antecedents of the rules) and minimum batch squares (to optimize the output).

“…There has been a lot of focus in recent years on developing renewable clean energy sources owing to the depletion of fossil fuels, and their burning also creates environmental pollution as well global warming. − The growing need for new forms of energy storage along with conversion has been driven because of fast consumption regarding non-renewable and non-availability of renewable sources. As a result of the intermittent nature of sustainable energy supplies, building new forms of large-scale energy storage devices has become an incredibly difficult research problem. − Additionally, the development of devices that can withstand tens of thousands of charge/discharge cycles without deteriorating in performance or capacity is required due to the extensive worldwide demand.…”

A massive amount of power is required to meet the worldwide need for gratifying human aspirations. As a result, the possible effect on the energy storage equipment is crucial to ensure a steady supply of energy. However, a supercapacitor is a potential device that provides a sustainable source of energy. In the current work, we presented a fabrication of Ag 2 Te at different concentrations of 0.006, 0.012, 0.025, 0.05, and 0.1 M via a hydrothermal approach for energy storage devices. A variety of analytical techniques were employed to assess its structure, morphology, and textural property regarding the fabricated electrode. Among different electrode materials, the Ag 0.025 Te electrode exhibited the large C s of 711.86 F g −1 , E d of 35.12 W h Kg −1 , and P d of 298.4 W Kg −1 at a current density of 1 A g −1 . The stability test of Ag 0.025 Te shows 92.96% retention of capacitance over 5000 GCD cycles with little destruction in the structure as determined by XRD. EIS responses indicated that the improved performance in 1.0 M KOH is because of low hydration sphere radius, strong ionic conductivity of K + , and less electrode resistance. The encouraging results suggest that the Ag 0.025 Te nanorod might provide an ideal cathode material for supercapacitor applications.

“…The strategic allocation of these banks brings benefits such as balancing the load during peak demand, storing intermittent renewable energy, and efficiently integrating renewable sources into the energy mix [2]. Therefore, the study of BB allocation is of utmost importance to ensure stable and reliable energy supply, especially with the increasing share of renewable energy sources in electricity generation [3].…”

This paper presents a study of electric power distribution systems, which include battery banks and electric vehicle charging.Emphasis is placed to detect and distinguish voltage disturbances, conductor breaks, and other events that commonly occur in distribution systems. The research uses free license software ATPDraw™ to accurately model distribution systems and replicate voltage characteristics. The study investigates the ideal location of electric vehicle chargers, battery banks and electrical voltage meters in distribution systems. For this purpose, the General Algebraic Modeling System (GAMS) will be used, which provides high-level mathematical optimization capabilities to improve the observability of the system. Research will focus on possible mitigation to the problems these factors can cause in the power distribution system and explore strategies to minimize their negative effects. The discoveries will help improve the system performance, stability, and reliability of power distribution systems and support the integration of electric vehicles and energy storage.
