Summary: Energy management strategy (EMS) is proposed to optimize the flow rate, discharge, and charge cycles of battery energy storage systems (BESS) by coordinating supercapacitors (SC) and photovoltaic systems (PV). The proposed EMS reduces the impact of high charge/discharge currents on the BESS and extends its life by using SC to handle transient energy mismatches. Simulation and hardware validation show improved performance of BESS and SC with the proposed EMS compared to conventional charge and discharge methods for hybrid energy storage systems (HESS). Economic analysis demonstrates the cost-effectiveness and economy of standalone PV and HESS systems with the proposed EMS over PV and BESS systems beyond 6 years of operation.

Summary: To address the increasing installation capacities of solar PV systems in desert areas, this study examines the impacts of ambient temperature, wind speed, dust accumulation, and cleaning frequency on energy production and optimal angles of PV panels. Results show higher energy production estimates using an isotropic model, and the cooling effect of wind speed reduces the operating temperature of thin-film panels. Cleaning the panels bi-monthly decreases annual energy production, and doubling the dust accumulation rate decreases energy production for all cases. The optimal tilt and azimuth angles vary within -3.0 degrees with dust accumulation rate.

Summary: The possibility of direct methanol synthesis from biomass pyrolysis syngas using Cu/ZnO/Al2O3 catalysts was investigated. Methanol yield was influenced by temperature, pressure, and time on-stream. The presence of CO2 in the syngas resulted in decreased catalyst performance, while CH4 did not affect performance. This research provides insights into the challenges of producing methanol from unconventional syngas and motivates future work to develop a robust catalyst for H2-deficient and CO2-rich syngas.
