Multi‐Strategy Synergy‐Based Differential Evolution for Large Wind Farm Layout Optimization

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Exploring clean energy alternatives to fossil fuels has become a major research focus worldwide. Wind energy is regarded as one of the most promising renewable energy sources due to its clean and sustainable nature. However, wake interactions among turbines significantly reduce power conversion efficiency, making wind farm layout optimization (

Post‐Arc Transient Dielectric Recovery Characteristics of Vacuum Interrupter in the Large‐Capacity Generator Circuit Breaker

open access: yesHigh Voltage, EarlyView.
ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)

Current‐Carrying Characteristics of High‐Voltage Land Cables With Different Grounding Methods for Low‐Frequency AC Transmission

open access: yesHigh Voltage, EarlyView.
ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

Practical Day‐Ahead Gas Generator Dispatch Optimisation for Enhancing the Reserved Capacity

open access: yesIET Smart Energy Systems, EarlyView.
Practical day‐ahead gas generator dispatch optimisation model is proposed to enhance the system reserved capacity. ABSTRACT In order to reduce carbon dioxide emissions, traditional coal‐fired power generation has been strictly limited in China recently, which has led to the problem of reserved capacity shortage. As one of the critical east provinces of

Evolution and Application of Instream Flow Methodologies to Small Hydropower Developments: An Overview of the Issues

open access: yes, 1985
ISBN 0-913235-37-7Methods for evaluating instream flow needs have evolved over the last 30 years resulting in two categories which are defined as 'standard-setting' and 'incremental.' Standard-setting methodologies refer to those measurement and ...

Enter Salmon: Trophic risk mediates riverine barrier‐crossing behaviours of parr

open access: yesJournal of Animal Ecology, EarlyView.
This study provides evidence that artificial riverine barriers alter juvenile Atlantic salmon behaviour in a context‐dependent manner, with predator presence further restricting movement and barrier interactions. By addressing the overlooked impacts of barriers on river‐resident parr stages, our findings contribute to a better understanding of ...

GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.
