Coordinated operational optimization of a variable-speed pre-expander and bypass for compressed air energy storage

The discharge process of compressed air energy storage (CAES) is challenged by inlet throttling loss and off-design mismatch caused by continuously declining cavern pressure. To address this issue, a coordinated operational optimization integrating a variable-speed pre-expander w...

Stereometric Molecular Engineering for Ultra‐Stable Aqueous Zinc‐Ion Batteries

ABSTRACT Aqueous zinc‐ion batteries (AZIBs) offer a safe and low‐cost energy storage platform yet are plagued by interfacial instability. Here, we investigate the relationship between molecular stereoisomerism and interfacial adsorption using inositol as a model system. Theoretic...

Synergistic optimization of the Han-to-Wei project under dry conditions via the MOEA/D-PFE: a case study of the Huangjinxia reservoir

Interbasin water transfer (IBWT) projects are essential for regional water security, yet complex trade-offs exist among reservoir operation objectives under variable hydrological conditions. Taking the Huangjinxia Reservoir of the Han-to-Wei River Diversion Project as a case stud...

A Grid-Forming Control Strategy Based on a Hybrid Approach Combining a Physical Model and LSTM for Photovoltaic and Energy Storage Systems

Traditional grid-forming converter (GFC) control faces fundamental challenges in maintaining DC bus stability during rapid power transients, primarily due to the limited dynamic response capability of source-side energy storage devices. To address this, this paper proposes a hybr...

Gas–Solid Two-Phase Flow-Induced Pipeline Wear in CAES: Enhancing Long-Term Durability for Energy Conversion and Storage Integration

In salt cavern compressed air energy storage (CAES) systems, slag particles entrained by high-pressure airflow can cause pipeline wear and flow instability, posing challenges to long-term operational safety. However, direct experimental studies are constrained by high-pressure, l...

Few-Shot SAR Object Detection with Prior Class Perceptron and Cross-Entropy

Few-Shot Synthetic Aperture Radar (SAR) object detection aims to identify and localize unseen categories using only a small number of annotated support samples. However, performance is fundamentally constrained by two coupled challenges: speckle noise and structured clutter cause...
