Abstract

Against the backdrop of global energy transition, photovoltaic (PV) power generation has witnessed rapid expansion, with China’s newly installed capacity in 2024 accounting for 52.4% of global additions. However, PV support systems face significant wind-induced vibration challenges in complex scenarios. This study systematically reviews advances in wind-induced vibration mitigation technologies for PV supports. First, structural characteristics and failure mechanisms are analyzed for fixed-axis, single-/dual-axis tracking, cable-suspended flexible, and offshore PV support systems. Second, synergistic applications of wind tunnel tests, numerical simulations, and field monitoring are reviewed to reveal nonlinear dynamic mechanisms such as vortex-induced vibration (VIV) and flutter. Third, many important dominant factors, such as aerodynamic parameters, geometric parameters, structural parameters, topographic effects are analyzed in detail. And design strategies such as prestress optimization, damping enhancement, and stiffness assignment are used to mitigate wind-induced vibration response in practice. Current challenges are discussed including unclear dynamic aeroelastic coupling mechanisms, insufficient scaling model similarity, and lack of standards for diverse scenarios. In future, developing high-fidelity multi-physical models, intelligent vibration suppression technologies, and cross-disciplinary frameworks will be emphasized to enhance system robustness and cost-effectiveness under extreme climates, supporting the global scaling of PV deployment.

Abstract

Environmental degradation and health concerns. In this context, the valorisation of organic waste through anaerobic digestion represents a promising alternative for sustainable household energy production. This study presents an experimental assessment of domestic biogas production from organic waste under local conditions in Chad. A pilot-scale anaerobic digestion system was designed and operated for a period of 30 days. The digester was fed with a mixture of vegetable organic waste and fresh cow dung used as inoculum. Key operational parameters, including temperature and pH, were regularly monitored throughout the digestion process. The system was designed to meet the cooking energy needs of a household of eight persons, and the technical feasibility of biogas production was evaluated. The experimental results showed that biogas production started from the tenth day of fermentation and increased progressively with the hydraulic retention time. The pH remained within a range favourable to methanogenic activity, while temperature variations were compatible with mesophilic digestion conditions. The observed biogas production confirmed the methanogenic potential of the selected organic substrates and demonstrated the suitability of the proposed low-cost digester for domestic energy applications. Biogas volume increases with daily feeding (1/60 of the useful volume) and a retention time of 30 days, reaching a maximum volume of 1,2 m³. This can reduce daily consumption by approximately 0,2 m³ of butane, 1,24 kg of charcoal, and 2,5 kg of firewood.The findings indicate that anaerobic digestion of household organic waste can contribute to sustainable energy supply, waste management improvement and reduction of pressure on forest resources in Chad. This study provides practical evidence supporting the deployment of small-scale biogas systems in similar socio-economic contexts.
