As multiple levels of electricity markets become intertwined and coupled across different time scales, regional power grids, while serving as hubs for trading channels, also face a series of operational risks, such as network congestion and ensuring security and reliability of supply. In response to the supply security scenario under market-oriented models, based on the analysis of intra-provincial transmission section blocking, an optimization method for inter-regional and inter-provincial power supply capability in the electricity spot market is proposed. Firstly, based on the correlation model of inter-provincial trading channels, inter-provincial physical interconnections, and intra-provincial transmission sections, the mechanism of intra-provincial network congestion formation is analyzed. Secondly, the Gradient Boosting Decision Tree algorithm predicts intra-provincial transmission section blocking, identifying critical sections that form the boundary for electricity purchases in the spot market. Finally, to maximize electricity purchases through inter-regional channels while considering constraints on DC power injection stability, the power supply capability of the target province is optimized. The proposed method is validated by analyzing it based on actual provincial networks. © 2025 Power System Technology Press. All rights reserved.

Flexible electrodes have significant potential in fields such as healthcare and neuroscience, as they enable comprehensive recording and analysis of human electrical signals, providing deeper insights into physiological conditions and the state of internal organs and tissues [1, 2]. However, commercial Ag/AgCl wet electrodes face issues such as dehydration,poor comfort, and insufficient mechanical strength, while other types of electrodes, like dry and semi-dry electrodes,also have their own limitations, including the higher contact impedance. In contrast, ionically conductive electrodes offer potential advantages such as transparency, stability, and low impedance, making them a promising alternative to existing electrically conductive electrodes [3]. Acrylic acid (AA)and 2-acrylamido-2-methylpropanesulfonic acid (AMPS) are commonly used in the synthesis of ionic gels, as they ionize in water to produce a large number of ions, helping to maintain moisture balance and reduce impedance caused by dehydration [4]. However, the presence of freely moving ions in the gel network can interfere with conductivity, highlighting the need to introduce new conductive networks to enhance performance [5].

All-safe liquid-state lithium-ion batteries(ASLS-LIBs) is of great interest as they can potentially combine the safety of all-solid-state batteries with the high performance and low manufacturing cost of traditional liquid-state LIBs. However, the practical success of ASLS-LIBs is bottlenecked by the lack of advanced separator technology that can simultaneously realize high performances in puncturing-tolerability,fire-resistance, and importantly, wetting-capability with non-flammable liquid-electrolytes. Here, we propose a concept of inorganic in-situ separator(IISS) by hybrid-sol physical crosslinking directly onto the electrode surface to address the above challenges. Particularly, the hybrid-sol is designed with silica nanoparticles as the building block and poly(vinylidene difluoride) nanoparticles as the crosslinking agent. The critical factors for controlling the IISS microstructures and properties have been systematically investigated. The advantages of the IISS have been confirmed by its fast wetting with various fireresistant liquid-electrolytes, customizable thickness and porous structures, robust interface with planar or three-dimensional(3D)-structured electrodes, and importantly, unexpected self-adaptability against puncturing. Enabled by the above merits, a fire-resistant ASLS-LIB is successfully assembled and demonstrated with stable electrochemical performance. This sol-crosslinked IISS may open an avenue for the studies on the next-generation separator technology, cell assembling, solid electrolyte processing as well as non-flammable secondary batteries.

Silicon photonics has provided a platform for the convergency of photonic devices and electronic circuits, facilitating the development of optical telecommunications and optical interconnects on chip[1]. As the basic building block of optical communication systems, electro-optic tuning is expected to be more compact, high bandwidth, energy efficient, and allow for CMOS-compatible fabrication in the future[2]. Resonator-based electro-optic tuning has attracted more and more interest due to the small footprint, enhanced light-matter interactions and high energy efficiency. Compared with microring and microdisk resonators, photonic crystal nanobeam cavities （PCNBCs） realize higher quality factors, stronger light-matter interactions, ultrasmall mode volume and a much larger free spectral range （FSR）[3].
