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.</p>\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}

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.

These evaluations obtain electrical conductivity, by noble approaches using DFT, which is related to intrinsic/extrinsic bands concepts and electrical rate-capability. Individual and alloyed transition metals-containing cathodes are investigated, namely, Li₂MSiO₄/Li₂M_0.5N_0.5SiO₄ (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/Li₂M_0.5N_0.5SiO₄ 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.

The study encompassed the analysis of various configurations of rock bed arrangements, including simple cubic, body-centred cubic, and face-centred cubic structures, along with their dimensions and the velocity of the heat transfer fluid (HTF) during the charging process. A transient three-dimensional reduced model incorporating symmetry planes was developed and subsequently validated. This approach has been shown to significantly minimize the extensive computational time typically required when the full model is adopted, while providing enhanced accuracy compared to commonly used models in existing literature, achieving an improvement in accuracy exceeding 5%. Moreover, the methodology that has been adopted enables a more comprehensive investigation of the storage system, thus facilitating the capture of local data. The findings indicated a pronounced effect of the arrangement of the rock bed, the rock dimensions, and the HTF velocity on the heat transfer within the thermocline rock bed thermal energy storage system. It was determined that the thermal energy storage was optimized when the rocks were arranged in a face-centered cubic configuration, which is associated with lower porosity. It was established that, at an HTF velocity of 3.84 × 10–4 m.s-1 and a rock diameter of 0.01 m, transitioning from a simple cubic arrangement to a face-centred cubic arrangement resulted in a 16.5% increase in capacity ratio and a 21.5% enhancement in exergy efficiency. Furthermore, it was determined that this transition also delayed the charging process by 39% (equivalent to 40 min).

They are used to power mobile phones, laptops and more recently electric vehicles (both two- and four-wheelers). The chemical behavior of the cells is rather complex and non-linear. For reliable and sustainable use of the cells for practical applications, it is imperative to predict the precise pace at which their capacity will degrade. More importantly, the lifetime of the cells must be predicted at an early stage, which would accelerate development and design optimization of the cells. However, most of the existing methods cannot predict the lifetime at an early stage, since there is a weak correlation between the cell capacity and lifetime. In this study for accurate forecasting of the battery lifetime, the patterns of the parameters such as cell current, voltage, temperature, charging time, internal resistance, and capacity were examined during charging and discharging cycle of the cell. Twelve manually crafted features were prepared from these parameters. The dataset for the features was created using the raw data of the first 100 cycles of 124 cells. Six ensemble and non-ensemble machine learning algorithms, namely, multiple linear regression (MLR), decision tree, support vector machine (SVM), gradient boosting machine (GBM), light gradient boosting machine (LGBM), and extreme gradient boosting (XGBoost), were trained with the features for predicting the life-cycle of the cells. The <i>R</i>² and root mean squared error (RMSE) values of MLR, decision tree, SVM, GBM, LGBM, and XGBoost were found to be 0.72 and 201, 0.83 and 155, 0.85 and 146, 0.92 and 100, 0.9 and 112, and 0.94 and 95, respectively. The prediction accuracy of lithium-ion cell life-time was found to be the best with the XGBoost algorithm. This shows that only first 100 cycles are required foraccurately predicting the number of cycles the lithium-ion cell can work for. Lastly, the results of the study were compared with the available studies in the literature. Three studies were chosen, and the RMSE of the method proposed in this study was found to be higher than the three studies by 43, 17, and 20.
