Thus, this study aimed to optimize the operating parameters of the photocatalytic degradation process using copper sulphide (CuS) and UV-visible irradiation via response surface methodology (RSM) to determine the relationship that exists between the most significant factors and the water quality parameters. The efficiency of the CuS photocatalyst was evaluated as a function of three input variables viz. (A) catalyst load (1–2 g/L), (B) mixing speed (60–120 rpm), and (C) exposure time (10–60 min) by using Box–Behnken design (BBD) adapted from RSM. Using chemical oxygen demand (COD), turbidity and colour removal as responses, a 15-run experiment matrix was generated by the BBD to investigate the interactive effects of the three abovementioned input factors. The correlation coefficients (R2) [0.9332, 0.9948, 0.9805] and their corresponding Adjusted R2 [0.8663, 0.9878 and 0.9545] values were near 1, suggested that a good fit existed between the developed statistical model and the collected data. For the use of CuS, the optimal solution suggested a COD (47.2%), turbidity (75.1%) and colour (48.3%) at a catalyst load (2 g/L), mixing speed (120 rpm), and exposure time (30 min), and maximum desirability of 96% removal efficiency. CuS was shown to be a viable photocatalyst for wastewater treatment under UV-vis irradiation under specific operating conditions.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 6","pages":"2922-2939"},"PeriodicalIF":3.5,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70077","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Renewable hybrid systems are typically recommended for this purpose; however, maintaining stability necessitates either a connection to the grid requiring electricity purchases from power plants, which are significant sources of pollution, or the deployment of extensive equipment to ensure system stability. This study examines four climatic regions in Iran, evaluating the selection between two storage systems, battery-hydrogen and battery–flywheel, through simulation and two-stage optimization. HOMER PRO software was utilized for both simulation and optimization, while the method based on the removal effects of criteria (MEREC) was employed for criteria weighting in decision-making, in conjunction with the technique for order of preference by similarity to ideal solution (TOPSIS) method. The findings indicate that the battery-hydrogen system is significantly more cost-effective, achieving savings of up to $211,327 in net present cost (NPC) and $0.738 in cost of energy (COE). Furthermore, the battery–hydrogen system demonstrates a greater reliance on renewable energy sources, increasing by up to 23.6% compared to the battery–flywheel system.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 5","pages":"2512-2529"},"PeriodicalIF":3.5,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The parameters of the interval charge were further optimized, and the waveform analysis based on MATLAB was used to analyze the vibration interference components.

Pyrolysis can convert biomass into sustainable chemicals and fuels. Therefore, the pyrolysis characteristics and the evolution of small molecular gases were studied using TG–FTIR–MS to investigate the pollutant formation mechanism during the pyrolysis of fast-growing grasses. The results revealed that the pyrolysis of the fast-growing grasses occurred in three stages, with weight loss rates of about 1%, 60%, and 3% in each stage. The heating rate had a minor effect on the total weight loss, which was about 65.7%. Increasing the heating rate improved the pyrolysis of the fast-growing grass, and the pyrolysis characteristic index at 30°C/min was 6.57 times that at 10°C/min, the peak emission intensities of NO, NH3, HCN, HNCO, CO, and CO2 all shifted to the high-temperature zone. In general, the heating rate had a noticeable promotion effect on the evolution rate of the small molecular gases, but has the opposite effect on the amount of gas generated.

The hybrid power system is a complicated nonlinear entity that highlights the significant issue of dynamic control owing to inadequate damping under fluctuating load conditions. In this respect, the present article explores the application of fuzzy logic based advanced controller for power system operations. The proposed controller's efficacy is demonstrated by a comparison of outcomes with other currently established controllers. We compare the fuzzy logic approach against an evolutionary algorithm namely COVID-19 technique. The results show that fuzzy logic works much better than the COVID-19 technique at reducing frequency variations. This is shown by the objective function values and demerit index calculations. The settling time of a fuzzy logic-optimized-PID (FPID) controller is more than 10 percent faster than that of a COVID-19-optimized PID controller. Further, fuzzy logic is used to optimize the MSPID controller. We found that the MSFPID has a 13.8 percent improvement in settling time with respect to FPID. We also conducted an investigation into the impact of EV integration on system stability. Results indicate that system dynamics improve with the increased presence of EVs. A new investigation with EVs for continuous load demand showed fast response from EVs against each load change. Furthermore, the proposed secondary controller exhibits robustness against practical system variations, hence confirming the healthiness of optimized gains. Finally, we test the secondary controller in a more complex dual-area hybrid power system, confirming its effectiveness.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 6","pages":"2772-2787"},"PeriodicalIF":3.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70066","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144244752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, a novel technique combining hydraulic fracturing and dissolution was proposed. The feasibility of this method was verified through simulations based on the distinct element method. Subsequently, the impact of weakened mechanical properties (deformation and strength) on fracture propagation was analyzed. Finally, the possibility of controlling the non-uniform propagation of fractures through treatment parameters was discussed. The results indicate that fractures tend to preferentially expand in weakened zones when deformation parameters or strength parameters deteriorate. Greater degradation of deformation and strength leads to larger fracture offset. The degree of fracture offset can be reduced by increasing the viscosity of fracturing fluid, based on which manual control of fracture offset can be realized. This study introduces a hybrid method combining physical and chemical actions for coal seam gas extraction, offering theoretical guidance for practical applications.","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 6","pages":"2842-2855"},"PeriodicalIF":3.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their decentralized nature poses challenges in resource coordination. This study proposes a bi-level optimization framework for distribution networks integrating peer-to-peer (P2P) energy trading and shared energy storage. The upper-level model minimizes distribution system operator (DSO) operational costs, including network losses and storage management, while ensuring voltage stability. The lower-level model enables prosumers to maximize P2P market profits through adaptive load adjustments and shared storage utilization. To address the nonlinear, high-dimensional optimization challenges, an improved Convex-Soft Actor-Critic (C-SAC) algorithm is developed, combining deep reinforcement learning with convex optimization to achieve privacy-preserving distributed coordination. Case studies on an IEEE 33-node system demonstrate that the framework increases prosumer profits by 56.9%, reduces DSO costs by 23.6%, and lowers network losses by 21.5% compared to non-cooperative scenarios. The shared storage system reduces capacity and power requirements by 20% and 14.1%, respectively. The C-SAC algorithm outperforms traditional methods (DDPG, SAC) in convergence speed and economic metrics, showing scalability across larger systems (IEEE 69/118 nodes).
