Combining wake redirection and derating strategies in a load-constrained wind farm power maximization [PDF]

Wind Energy Science
Power derating and wake redirection are two wind farm control techniques proposed in the last decade as means for increasing the overall wind farm power output.

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

Advanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

Analysis of small signal stability in direct-drive wind farm under wind power generation variations

电力工程技术
The small-signal stability problem of large-scale grid-connected wind farms consisting of permanent magnet synchronous generators (PMSGs) under wind power variations is addressed in this paper, with focus placed on the DC-link voltage timescale.

Harmonizing Rigidity and Flexibility: Embedding COF Quantum Dots Into Extracellular Matrix Gel as Carbon Monoxide Depot for Acoustically Triggered Time‐Programmable Anti‐Infective Therapy

Advanced Science, EarlyView.
A rigid‑flexible integrated CO depot is engineered by embedding rigid COFQDs into a flexible ECM gel network. The rigid framework enables high‑capacity CO storage and sonodynamic bacterial killing, while the flexible ECM gel controls sustained CO release, collectively eradicating multidrug‑resistant infection and promoting scarless healing.

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Do Tax Incentives for Farmland Leases Increase Farm Supply? Evidence From Iowa's Beginning Farmer Tax Credit

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT In recent decades, agriculture has become increasingly concentrated through horizontal mergers and acquisitions via corporate entities, and policy makers are concerned this will be exacerbated by the aging population of farm operators. To reduce market concentration in agriculture, many states have enacted policies to entice new prospective ...

Distribution Strategy of Wind Farm Active Power and Its Implementation

Kongzhi Yu Xinxi Jishu, 2013
Currently, average distribution is generally adopted for the active power control instruction of wind farms. If the wind speed differs much among wind turbines in the wind farm, the output active power of the wind farm may as well differ much from the ...

Assessing Household Welfare in Response to Rising Food Prices in The Gambia

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines how rising food prices affected household welfare in The Gambia using nationally representative data from the 2015/16 Integrated Household Survey (IHS‐3). The analysis reflects household consumption behavior and market conditions prevailing during that period and provides a structural benchmark for understanding ...

Integer programming for optimal yaw control of wind farms [PDF]

Wind Energy Science
It is well-known that wakes caused by wind turbines within a wind farm negatively impact the power generation and mechanical load of downstream turbines. This is already partially considered in the farm layout.
