Hydrogen energy plays an increasingly vital role in global transformation. However, existing electric–hydrogen coupled integrated systems (IESs) face two main challenges: achieving stable operation when with large-scale networks and integrating optimal dispatching code physical systems. This paper conducted comprehensive modeling, optimization joint simulation verification of the above IES. Firstly, a low-carbon economic model IES considering carbon capture power plants is established at layer. Secondly, by organizing selecting representative data dispatch model, planning integration wind, photovoltaic (PV), diesel storage constructed The proposed coupling mainly consists following components: alkaline electrolyzer, high-pressure hydrogen tank compressor proton exchange membrane fuel cell. this achieved mode system can maintain control despite unpredictable changes renewable sources, showing strong resilience reliability. also integrate for operation, enhancing utilization absorption PV wind power. Co-simulation showed that optimized has 29.42% reduction total cost 83.66% decrease emissions. Meanwhile, proved system’s harmonic distortion rate controlled below 3% both grid-connected islanded modes, indicating good quality.

The increasing penetration of renewable energy sources (RESs) into medium-voltage (MV) and low-voltage (LV) power systems presents significant challenges in ensuring grid stability sustainability. Advanced conversion technologies are essential to mitigate voltage frequency fluctuations while meeting stringent quality standards. RES-based generation typically employ multistage electronics achieve: (i) maximum point tracking; (ii) galvanic isolation transformation; (iii) high-quality injection the grid. In this context, paper provides a comprehensive review up-to-date isolated DC–DC converter topologies tailored for integration RES. As contribution support topic, recent advancements solid-state transformers (SSTs) explored, with particular emphasis on adoption wide bandgap (WBG) semiconductors technologies, such as silicon carbide (SiC) gallium nitride (GaN). These devices have revolutionized modern by enabling operation at higher switching frequency, enhanced efficiency, increased density. By consolidating state-of-the-art identifying technical challenges, offers insights suitability light future trends, serving valuable resource optimizing grid-connected sustainable systems.

In this paper, a multi-objective mixed integer linear programming (MOMILP) approach is proposed for the optimal planning of battery energy storage systems (BESSs) and interlink converter (ILC) in hybrid AC/DC microgrids (HMGs). The ILC backbone HMG, facilitating power exchange between sub-grids. It plays vital role enhancing stability HMG by balancing subsystems. Economically, enables transfer surplus lower-cost AC DC microgrids. Therefore, selecting an size critical from both technical economic perspectives. However, existing studies have overlooked sizing its associated stress factors HMGs. This paper proposes HMGs that considers calendar cyclic ageing BESSs. performance strategy compared with most widely used methods. results confirm superiority terms efficiency.

The expanding integration of wind and photovoltaic (PV) energy is disrupting the power system planning processes. Their incorporation poses limitations to forecasting due their inherent variability. This review compiles a total ninety studies conducted published between 2019 2025, presenting for first time an integrated approach that simultaneously optimizes generation, transmission, storage, flexibility resources given high ratios renewable generation. We present systematic taxonomy conflicting optimization approaches—deterministic, stochastic, robust, AI-enhanced optimization—outlining meaningful mathematical formulations, real-world case studies, achieved trade balance optimality, scale, runtime. Emerging international cooperation clusters are identified through quantitative bibliometric analysis, method selection in practice illustrated using table with concise snapshots study excerpts. Other issues analyzed include long-duration centralized versus decentralized roadmap delineation, regulatory market drivers grid expansion. Finally, we gaps literature—namely, resilience, sector coupling, policy uncertainty—that warrant further investigation. provides critical insights researchers planners by systematically integrating methodological perspectives tackle real-world, application-oriented problems related generation transmission expansion models amid significant uncertainty.

The purpose of this study is to make evaluation regarding significant issues about the customer expectations and technical competencies for successfully integration batteries in microgrid systems. In direction, six different requirements are identified by considering literature review results. weights criteria computed with sine trigonometric Pythagorean fuzzy (STPYF) decision making trial laboratory (DEMATEL). Moreover, also ranked using a newly developed technique called "ranking geometric mean similarity ratio optimal solution" (RATGOS). This new methodology integrated STPYF sets. main contribution that it can be much easier increase efficiency battery systems priority analysis. proposing ranking-based decision-making (RATGOS) has an increasing impact on methodological originality. On other side, owing DEMATEL approach weighting, causal directions between these factors understood. situation accepted as important superiority model comparing previously generated ones. It determined storing energy most critical expectation effectiveness process. Furthermore, ranking results demonstrate generating smart control have higher performance proposed generates similar findings previous Based results, some strategies should implemented storage processes Within framework, choosing right vital importance. Technological infrastructure necessary achieve goal. Similarly, provide cyber security processes. way, possible work more safely against external interventions.
