Energy–Carbon Synergy in Data Center-Based Energy Hub: Optimal Trading Decision in Coupled Electricity–Heat Markets Under Ladder-Type Carbon Trading

Data centers are becoming flexible prosumers in integrated electricity–heat systems (IEHSs) because of their large energy demand, workload flexibility, and waste-heat recovery potential. Coordinating these resources can improve energy utilization and carbon performance while supp...

Scriptless cross-chain deferred asset transfer for AIoT

In AIoT service scenarios such as sensing-as-a-service and edge AI outsourcing, a service requester may need to establish a payment commitment before service execution, while final transaction should be deferred until service delivery is verified. When the requester and the provi...

SEB-IOTA: a trust-driven and hierarchically verified data broadcasting framework for smart grids with HMM-anchored reputation dynamics

Purpose To address secure, low-latency broadcasting of high-value data in smart grids, this paper aims to propose secure and efficient broadcast framework based on IOTA (SEB-IOTA). It tackles three key bottlenecks: single points of failure in centralized architectures, poor real-...

Optimization and analysis of phase-locked loop for grid-following inverters with weak grid connection

Purpose This study aims to analyze and enhance the stability of three-phase grid-connected inverters in weak grid environments, with a particular focus on the negative impact of the phase-locked loop (PLL) on system stability. Design/methodology/approach A small-signal transfer f...

A Downscaling Method for Cloud-to-Ground Stroke Density and Its Improvement on Tower-Level Lightning Hazard Risk Identification

Cloud-to-ground (CG) stroke density is key for lightning hazard risk assessment, but conventional grid-cell methods face an inherent trade-off between spatial resolution and statistical confidence. To address this issue, this study takes Fangchenggang City, Guangxi, as the study...

Research on assessment and adaptive correction technology of power system protection fixed value mismatch

With the increasing integration of distributed energy resources, the issue of protection setting mismatch caused by overlapping fast tripping zones in traditional radial distribution networks has become increasingly prominent, affecting the reliability and selectivity of system p...

Energy-efficient coordinated scheduling of stacker cranes and automated guided vehicles in a smart-meter automated storage and retrieval system

Automated storage and retrieval systems require coordinated scheduling of stacker cranes and automated guided vehicles because their operations are coupled through task precedence, shared buffers, resource conflicts, and energy-related travel costs. This study examines a smart-me...

Series-Connected Grid-Following and Grid-Forming Hybrid Control Strategy for VSC-HVDC Converters to Enhance Transient Voltage Stability in Receiving-End Power Grids

With an increase in the High-Voltage Direct Current (HVDC) infeed, the strength of the receiving-end AC grid decreases, leading to transient voltage instability. Voltage source converter (VSC)-HVDC stations have a large unit capacity and high controllability, offering great poten...

Interfacial engineering enables air-stable Li 5 FeO 4 prelithiation additives for long-Life LiFePO 4 |graphite batteries

Abstract Lithium iron phosphate (LiFePO4, LFP)|graphite (Gr) full cells are widely used in large-scale energy storage owing to their safety and long cycling stability. However, irreversible lithium consumption during solid electrolyte interphase (SEI) formation depletes the limit...
