Hierarchical dynamic active wake control for wind farm power generation enhancement and fatigue load suppression with participation in secondary frequency regulation

International Journal of Electrical Power & Energy Systems
Wind farms (WFs) are required to participate in secondary frequency regulation (SFR), and operate in power reference tracking (PRT) or power generation enhancement (PGE) modes.

Design and Performance of a High‐Efficiency Inhibitor: Synergistic Effect of Modified Chitosan and Boron Nitride Nanosheets on Steel Protection

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal corrosion causes significant economic losses and safety hazards, underscoring the urgent need for effective, environmentally friendly corrosion inhibitors. In this study, an organic–inorganic composite inhibitor, chitosan–glucose–BN (CS–GL–BN) was developed to protect Q235 mild steel in a 3.5‐wt% NaCl solution.

Analysis of grid-connected operation characteristics and limit access capacity of offshore wind farms

Energy Reports, 2022
Wind power is a relatively ripe renewable energy power generation technology, which has the superiority of large-scale development and utilization. Large-scale deep-sea wind farms are a significant direction for wind power development.

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Challenges in All-DC Offshore Wind Power Plants

Energies, 2021
As the size and distance from shore of new offshore wind power plants (OWPPs) increase, connection to shore using high-voltage (HV) direct-current (DC) technology becomes more cost-effective.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

When Do Robots Go Green? Unveiling Mechanisms, Thresholds, and Spillovers of Industrial Robotics on Global Ecological Capacity

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper examines the relationship between industrial robotics adoption and ecological capacity, measured by biocapacity, using panel data from 50 countries over the period 2000–2024. We investigate the transmission mechanisms, non‐linearities, spatial spillovers, and heterogeneity characterizing this relationship.
