However, the reliability of the PV-based HESS against frequent load variation and irregular solar irradiance demands a robust power management scheme (PMS) and associated control strategies. This paper presents an enhanced DC voltage stabilization control strategy for robust PMS for the PV-based HESS. The proposed control approach ensures stable DC link voltage regulation, improving the overall efficiency and thus reliability of the overall system. A comprehensive analysis of the system dynamics and control objectives is conducted under different operating conditions, leading to the development of a combined tilt-integral (TI) and fractional proportional-integral (FOPI)-based controller. The controller parameters are estimated using the particle swarm optimization (PSO) technique and a gradient-free Nelder–Mead simplex search (NMSS) algorithm for optimizing the time-domain parameters. Thereafter, the dynamic performance of the presented PMS is investigated through extensive experimentation analyzed in terms of various parameters. The investigation suggests that the proposed control scheme outperforms the conventional control approach by a significant margin of 60.81% and 40.42% in steady-state error and peak overshoot, respectively. Also, the state of charge (SOC) consumption of the battery is reduced by 8.46%, thus increasing the overall lifespan of the energy storage system. Therefore, the proposed control strategy offers a viable solution for ensuring stable and efficient operation of PV-based energy storage systems, contributing to the advancement of renewable energy integration and grid resilience.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study applies the Taguchi method and utility concept to obtain the optimum parameters for two objective functions: maximum heat transfer rate and thermal effectiveness of the BHE. A validated numerical heat transfer model with a fully implicit method is applied to compute the transient heat transfer in the BHE. The Taguchi optimization results revealed that the optimal factors (denoted with letters and numbers showing their levels) for achieving the maximum heat transfer rate and thermal effectiveness are A1B3C2D1E3F3G3H3 and A3B3C2D3E3F3G1H1, respectively. This resulted in an optimal heat transfer rate of 120 W/m and a thermal effectiveness of 69.3%. Using the utility concept method, a single set of optimal parameters (denoted by their levels as A3B3C3D2E3F3G2H3) is obtained to maximize the performance of the BHE. These parameters yielded an optimum heat transfer rate of 87.3 W/m and thermal effectiveness of 54.6%. Finally, analysis of variance (ANOVA) showed that ground thermal conductivity, the inlet temperature of the working fluid, and borehole depth are the most influential parameters affecting the performance of the BHE. The study provides crucial information for performance improvement, enhanced energy savings, reduced environmental impact, and optimization of a hybrid ground source heat pump system that can be integrated with borehole thermal energy storage.","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/est2.70145","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When pilots, astronauts, and race car drivers get under the effect of higher G-forces, their blood accumulates in the lower parts of their bodies, although their heart rates increase, and their cardiovascular systems supply less blood to their brains and lungs. When insufficient oxygenation of the brain causes loss of consciousness, incapacitated pilots or drivers may cause accidents resulting in serious injury or death. Pilots receive high-G training to prevent gravity-induced loss of consciousness (G-LOC). Wearing anti-G suits on flights may help to decrease the G-LOC. While the maximum G-Force tolerance of a normal person is approximately 4G, it increases to 9G when a pilot is with equipment. In the experiments at 46.2G, a pilot, John Stapp, managed to barely stay conscious; his retinas were severed, but he got his normal vision back after a day and he showed that position and safety precautions could help the human body withstand high amounts of crash forces. This research helped to develop several safety changes in automobiles. Indycar is America's top single-seater racing series. The crash recorders installed in their cars have shown that as long as safety systems are in place, the Indycar drivers can tolerate impacts over 100G without serious injuries. This study makes a thermodynamic assessment of the effects of the high G-force when the race car drivers and the jet pilots are tentatively subject to it but get out of that effect when their task is over.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individual and alloyed transition metals-containing cathodes are investigated, namely, Li2MSiO4/Li2M0.5N0.5SiO4 (M, N = Mn, Fe Co, Ni). Our analysis focused on the electrical properties, including band-gap (BG) and rate-capability, utilizing the GGA(+U)/LSDA(+U) approximations. The electrical properties of the Li2MSiO4/Li2M0.5N0.5SiO4 materials were thoroughly examined by evaluating both the band-gap and electrical rate-capability. For band-gap assessment, we considered two types of band-gap (ILBG/ELBG); while, two criteria (Delta/CCTB) were employed to evaluate the rate-capability. The evaluation of band-gap indicated that all the considered materials exhibited low conductivity. Nonetheless, our findings highlight that the electrical rate-capability of a cell holds greater practical importance than the band-gap property. Our approaches provided reliable predictions for the rate-capability of the alloyed transition metals materials. The theoretically obtained results and conclusions are validated by available experimental data. We conclude that the rate capability approaches are more important than sole band gap. Also, the CCTB approach is more applicable for this electrode family than the Delta. This study can help understanding of behaviors of the alloyed electrode materials.

However, the processability and thermal storage density of which are inversely proportional to the content of adsorption backbone. To relieve the above contradiction, this paper proposed an in situ construction method for a phase-changeable adsorption backbone (PCPB). The in situ growth strategy avoided the processing difficulties caused by high stirring viscosity owing to the addition of large dosage of adsorption filler. Moreover, PCPB prepared via in situ polymerization of octadecyl methacrylate and 1,6-hexanediol diacrylate in PCM matrix presented obvious endothermic peak with latent heat of 89.5 J g−1, which could undoubtedly alleviate the decay rate of CPCM's latent heat. In details, the maximum PCM loading percentage of PCPB could reach 50 wt%, and CPCM at this loading amount could reach latent heat as high as 149.7 J g−1 and maintain form-stable without leakage even after thermal storage saturation. In addition, with the growth of PCPB in the phase change matrix, the 50% degradation temperature increased dramatically from 164.6°C to 350.0°C.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143380861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
