The decrement in PSEC of 176.2 kJ/kgTS and increment in solubilization of 7.5 % was due to the effective action of APG surfactant.

Based on the Smoothed Particle Hydrodynamics (SPH) method, a two-dimensional wave tank is established to study wave interactions with this hybrid multi-raft system. To validate the proposed SPH model, a laboratory experiment is conducted to assess the hydrodynamic performance of a triple-raft structure. The SPH model is then applied to compare hydrodynamic performance between double and triple raft configurations. This study reveals the interaction and interference effects between waves and the rafts. The results indicate that, compared to the double-raft structure, the addition of a third raft significantly enhances the pitching motion of the original two rafts. The effects of the raft width, the resonance mode, and the mooring system are analyzed. The findings demonstrate that resonance dominates the wave energy extraction performance at specific frequencies. The double-point mooring mode facilitates the device's absorption of multi-period waves, while its mooring forces are significantly higher than that of the single-point mooring system.

Despite the existence of various techniques, many face challenges in achieving a balance between precision, robustness, computational efficiency, and execution time. In this paper, we present a novel hybrid algorithm, Differentiated Creative Search combined with Newton-Raphson (DCS-NR), designed to improve the accuracy and efficiency of PV parameter extraction. DCS employs a dual-strategy mechanism that balances exploration and exploitation through divergent and convergent thinking, ensuring a comprehensive search for solutions. The Newton-Raphson method further refines the parameters optimized by DCS, minimizing the discrepancy between estimated and measured currents, and consequently improving power estimation. The proposed approach is evaluated on three distinct models: Single Diode Model (SDM), Double Diode Model (DDM), and PV Module Model (PMM). Among the different models tested, DCS-NR consistently delivers superior accuracy. For example, it achieves an RMSE of 7.75392 × E−04 for the RTC France SDM and 1.77454 × E−04 for the PVM 752 cell, outperforming ten state-of-the-art metaheuristic algorithms. Moreover, DCS-NR demonstrates remarkable computational efficiency, requiring only 0.830 s on average for the RTC France SDM, which is considerably faster than algorithms such as Flying Foxes Optimization (251.5 s). Furthermore, it proves highly effective in real-world conditions, under varying irradiance and constant temperature, as well as vice versa. The method consistently converges within approximately 100 iterations, showcasing rapid optimization capabilities. These findings highlight the potential of DCS-NR as a powerful and versatile tool for photovoltaic parameter extraction, capable of addressing diverse and challenging scenarios.</div></div>","PeriodicalId":419,"journal":{"name":"Renewable Energy","volume":"245 ","pages":"Article 122764"},"PeriodicalIF":9.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we examine the balance between short-term losses in hydropower generation and the potential for compensatory benefits in the form of revenue from recreational ecosystem services, irrespective of the direct beneficiary. Our framework integrates a fish habitat model, a hydropower optimization model, and a recreational ecosystem service estimate to evaluate different environmental flow scenarios. The optimization process gives three outflow release scenarios, informed by previous streamflow realisations (dam inflow), and designed environmental flow constraints. The framework is applied and tested for the river Kuusinkijoki in North-eastern Finland, which is a habitat for migratory brown trout and grayling populations. We show that the revenue loss due to the environmental flow constraints arises through a reduction in revenue per generated energy unit and through a reduction in turbine efficiency. Additionally, the simulation results reveal that all the designed environmental flow constraints cannot be met simultaneously. Under the environmental flow scenario with both minimum flow and flow ramping rate constraints, the annual hydropower revenue decreases by 16.5 %. An annual increase of 8 % in recreational fishing visits offsets the revenue loss. The developed framework provides knowledge of the costs and benefits of hydropower environmental flow constraints and guides the prioritizing process of environmental measures.</div></div>","PeriodicalId":419,"journal":{"name":"Renewable Energy","volume":"244 ","pages":"Article 122756"},"PeriodicalIF":9.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
