Coordinated dispatch of virtual power plants in distribution systems under ramping constraints and uncertainties

This paper proposes a coordinated dispatch framework for distribution systems with virtual power plants (VPPs) that addresses both substation ramping constraints and load-ramping uncertainty. A data-driven quantile-regression temporal convolutional network (QR-TCN) is developed t...

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...

QTL mapping for spike length and candidate gene identification in wheat spike development (Triticum aestivum L.)

Spike length (SL) is a crucial factor influencing yield in wheat ( Triticum aestivum L.). In this study, a recombinant inbred line (RIL) population derived from the cross between Guixie 3 and Avocet S was utilized for genetic mapping of quantitative trait loci (QTL) controlling s...

RDIC-MSCKF: Risk–Direction-Decoupled and Innovation-Calibrated MSCKF for Stereo Visual-Inertial Odometry

Filtering-based stereo visual-inertial odometry often assigns fixed or uniformly scaled covariance to tracks accepted by the front-end, although accepted observations can differ in terms of tracking reliability, local directional identifiability, and agreement with the batch-leve...

Predictive coordination control algorithm for cooling system of a 140-kW proton exchange membrane fuel cell stack based on decoupling of component function

Operating temperature dominates performance and durability of proton exchange membrane fuel cell, and optimal control of operating temperature is essential for high performance and longer lifespan. Hence, this paper proposes predictive coordination control algorithm for cooling s...

Seasonal Reversal of Polarity Dominance in High‐Current Cloud‐to‐Ground Return Strokes Over East Asian Midlatitudes

Abstract Extreme positive cloud‐to‐ground lightning over East Asian midlatitudes exhibits a spring–autumn double maximum hidden by the familiar winter climatology. Using 1,838,538 return strokes with absolute peak currents at least 200 kA during 2006–2024, we resolve its annual c...

Study on Threshold Values of Safety Control Indicators for Rapid Drawdown of 200~300 m High Earth-Rockfill Dams

High dams and large reservoirs serve flood control, power generation, water supply and ecological security, where rapid safe drawdown is vital for emergency handling and long-term safe operation. Targeting undefined rapid drawdown control standards for over-200 m ultra-high earth...
