Active cell balancing is essential for maintaining uniform charge distribution across cells, improving the lifespan, capacity, and safety of LIBs. The paper presents a comprehensive performance assessment of an optimized active cell balancing circuit based on a buck-boost converter. The research work proposes a novel approach for active balancing circuits, integrating advanced control algorithms and high-efficiency power electronic components for efficient and fast results. Simulation studies are undertaken in MATLAB-Simscape to estimate the effectiveness of the cell balancing model. Circuit performance across different load types shows slight variations. For resistive load, balancing occurs in 33 s at 71% state of charge (SOC), reaching 100% SOC in 242 s. For resistive and inductive load, balancing occurs in 32 s at 70% SOC, reaching full charge in 240 s, and for resistive, inductive, and capacitive load, balancing occurs in 33 s at 70% SOC, stretching to 100% SOC in 239 s. The study provides valuable insights into the design and implementation of high-performance active balancing circuits, paving the way for more reliable and efficient LIB packs.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581809","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}

RCC is an emerging technology that integrates CO2 capture and conversion processes, potentially offering economic and environmental benefits over traditional carbon capture, utilization, and storage methods. A survey of 1032 respondents was conducted using the one-and-one-half bounded dichotomous choice format with a spike model. The results indicate an average annual WTP of KRW 4697 (USD 3.58) per household per month for 5 years, translating to a total national WTP of KRW 561.65 billion (USD 427.82 million). Demographic analysis reveals that women and residents of metropolitan areas have a higher WTP. Interestingly, the level of prior knowledge about RCC did not significantly affect WTP, possibly due to the prevalent belief that climate change mitigation is primarily a government responsibility. This study provides the first socioeconomic valuation of RCC technology, offering valuable insights for policymakers and researchers. The findings suggest substantial public support for RCC development, highlighting its potential as a key strategy in South Korea's climate change mitigation efforts. However, to increase public acceptance and investment in RCC, there is a need for broader discussions on individual roles in addressing climate change, alongside government initiatives.\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":"7 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554608","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 gravel acts as a heat transfer medium, dissipating heat from the panels to the surrounding air, thereby reducing their temperature. A comparative analysis was conducted between systems with and without porous media. The results demonstrated that integrating porous media enhances the performance of the hybrid photovoltaic/solar chimney. Specifically, the electrical energy output increased from 395.56 W without porous media to 447.98 W with porous media at noon. The peak electrical efficiency was observed at the beginning of the test, reaching 14.51% without porous media and 15.22% with porous media at 9 a.m. At midday, electrical efficiency was 11.5% without porous media and 12.2% with porous media. However, as solar radiation intensity increased, efficiency gradually declined. On the other hand, the thermal efficiency of the chimney with porous media was lower compared to the system without it, with values of 53.45% and 59.611%, respectively.

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.
