Comparative Performance Analysis of Various Flat Plate Solar Collectors Incorporating Spiral and Square Arrangement of Circular Type Riser Tube

open access: yesEnergy Science &Engineering, EarlyView.
Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.

Adaptive Fuzzy Energy Management of Wind‐Battery Systems With Flexible Desalination Load

open access: yesEnergy Science &Engineering, EarlyView.
An adaptive fuzzy energy management strategy is proposed for a wind‐battery‐powered reverse osmosis desalination system. The controller dynamically adjusts the desalination load based on wind power availability and the battery state of charge to reduce battery stress.

A Simplified Two‐Vector Approach for Common‐Mode Voltage Reduction in Model Predictive Control Drives of Permanent Magnet Synchronous Motor

open access: yesEnergy Science &Engineering, EarlyView.
In this study, a modified model predictive control scheme is proposed, in which a dedicated weighting factor is incorporated into the cost function to explicitly account for common‐mode voltage (CMV) effects during the control process. This modification leads to a significant reduction—up to 40%—in the magnitude of the generated CMV.

A Novel Bipolar DC Connection Strategy for Photovoltaic Power Plants With a 50% Reduction in DC Cabling Length

open access: yesEnergy Science &Engineering, EarlyView.
Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

Optimizing Fabrication of Plasma‐Driven CuO Shell Over Porous Al2O3 Substrate to Meet Coating Issues

open access: yesJournal of the Chinese Chemical Society, EarlyView.
In situ Cu2O‐to‐CuO transformation during plasma electrolytic oxidation of aluminum alloys. ABSTRACT A plasma‐driven in situ conversion strategy was developed in which Cu2O nanoparticles introduced into an alkaline phosphate–hydroxide electrolyte undergo oxidative transformation to CuO within plasma micro‐discharge channels during plasma electrolytic ...

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

open access: yesThe Journal of Wildlife Management, EarlyView.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.
