In Algeria, where the energy sector relies heavily on fossil fuels, integrating renewable energy systems is essential for enhancing energy security and reducing environmental impacts. This study focuses on optimizing a hybrid renewable energy system (HRES) for off-grid applications in the Hassi Messaoud region of Algeria to balance technical performance, economic viability, and environmental sustainability. A hybrid system consisting of photovoltaic (PV) panels, wind turbines (WTs), fuel cells (FCs), and diesel generators (DGs) was modeled and optimized using a genetic algorithm (GA). The optimization process aims to minimize the annual cost of the system while ensuring high reliability, as measured by the loss of power supply probability, and maximizing the use of renewable energy. A particle swarm optimization (PSO) approach was also implemented for comparison, highlighting the advantages of the GA in terms of cost distribution and system reliability. The optimized HRES demonstrated that renewable sources (PV and WT) provided 77% of the total energy demand, with an overall system cost of 0.18080 <span><math><mrow><mi>$</mi><mo>·</mo><msup><mrow><mrow><mi>kWh</mi></mrow></mrow><mrow><mo>−</mo><mn>1</mn></mrow></msup></mrow></math></span>, significantly lower than recent studies, which reported costs between 0.213 and 0.609 <span><math><mrow><mi>$</mi><mo>·</mo><msup><mrow><mrow><mi>kWh</mi></mrow></mrow><mrow><mo>−</mo><mn>1</mn></mrow></msup></mrow></math></span>.

Economic analysis showed that DGs and FCs accounted for 44% and 24% of the annual cost, respectively, highlighting the impact of backup systems in ensuring reliability. Sensitivity analysis under varying load demands and renewable energy availability confirmed the robustness of the system, and the GA approach was found to be more effective than PSO in maintaining cost efficiency and reliability. Additionally, the social analysis highlighted a renewable fraction of 91.5%, emphasizing the contribution of the system to sustainable energy practices. These findings validate GA-based optimization as a superior method for designing cost-effective, reliable, and environmentally sustainable HRES, offering significant potential to reduce fossil fuel dependency in industrial applications.

Adding nanoparticles to molten salt to create nanofluids is known to significantly improve the thermal conductivity of the molten. However, nanoparticle agglomeration is inevitable and substantially affects the thermal conductivity of molten salts. Moreover, the mechanisms whereby agglomeration influences thermal conductivity remain unclear. This paper presents an innovative multiscale coupling model that combines molecular dynamics (MD) simulations with the lattice Boltzmann method (LBM) to investigate the thermal conductivity of CuO nanoparticles in ternary NaCl–KCl–LiCl molten salt-based nanofluids. Both nonaggregated and aggregated states were considered. After conducting MD simulations at the microscale to examine the thermal contact resistance at the interface between nanoparticles, we employed the LBM to determine the effective thermal conductivity of the nanofluids at the mesoscale. The findings reveal the formation of significant heat flow channels in nanofluids containing nanoparticles. However, an increase in the thermal contact resistance reduces these channels in agglomerated particles, potentially reducing the thermal conductivity compared with that in the nonaggregated nanofluids. In cluster-like structures, fewer nanoparticles are positioned within heat flow channels, in contrast to chain-like arrangements. This reduction limits the enhancement in the thermal conductivity and minimizes variations in the thermal conductivity due to differences in the aggregate particle number and orientation. Furthermore, the thermal conductivity exhibited notable variations with varying agglomerated nanoparticle diameters at identical mass fractions. Both smaller and larger particles can increase the level of contact thermal resistance, ultimately reducing the thermal conductivity.</div></div>","PeriodicalId":100472,"journal":{"name":"Energy Storage and Saving","volume":"4 1","pages":"Pages 70-82"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520055","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}

Elevated temperatures in EV batteries primarily result from thermal instability during various operating, traveling, and charging conditions. In formula student electric vehicle (FSEV) competitions, where efficiency and reliability are critical, effective cooling of the battery pack (BP) is essential. This study analyzed the cooling performance of an air-cooled thermal management system using relevant system parameters and precise thermal modeling through CFD simulations. Various cooling parameters, such as coolant flow rate, fan speed, and cooling channel geometry, were systematically adjusted to evaluate their effects on BP temperature distribution, thermal equilibrium, and overall performance. Key metrics, including maximum temperature and temperature distribution within the battery module, were used to compare simulation results and optimize outcomes for future applications. Experiments validated the simulations of the optimal solution. The results of this investigation provide valuable insights for designing and improving active cooling systems for LIBPs in FSEVs. The average variance of the obtained temperature data was 4.256% based on simulation results. At an air velocity of 17 m·s⁻¹, the BP temperature remained within the ideal range of 30–40 °C.

Wind energy conversion systems (WECSs) can accept fixed speed and variable speed (VS) operations.

Maximum power point tracking (MPPT) systems are essential for maximizing the efficiency of wind energy generation in wind turbine (WT) installations linked to power grids. This study introduces a hybrid fuzzy logic controller-based MPPT (FLC-MPPT) for WTs connected to permanent magnet synchronous generators (PMSGs) to accurately determine the maximum power output of WTs. This study employs a three-phase back-to-back converter to link a PMSG to a utility grid. The reference signals for pulse width modulation controllers comprise two-phase system currents. It constructs a converter that can transfer electrical energy in both directions using insulated-gate bipolar transistor technology and is powered by a battery. The machine-side converter uses model predictive control for the present control loop. Given the generator’s susceptibility to changes in wind conditions, this factor is of the utmost importance. A WT simulation was conducted using MATLAB/Simulink and an FLC methodology was employed. The model used a PMSG. Measurements of rotor speed, power, induced voltage, and current were taken in relation to variations in wind speed.
