Hydrogen energy system modeling method, electronic device and storage medium

PendingCN122287134AAccurately reflect true impactImprove physical accuracyIntegrated energy systemProcess engineering
This invention discloses a modeling method, electronic device, and storage medium for hydrogen energy systems. The method includes: establishing a hydrogen production mass flow model for an electrolyzer, and using a multi-condition linearization method to handle the nonlinear operating efficiency of the electrolyzer; establishing a storage mass flow model for a hydrogen storage tank, dynamically characterizing its effective capacity based on the tank's physical volume, operating pressure, and ambient temperature parameters; constructing a hydrogen mass flow bus, linking the electrolyzer's hydrogen production variable and the storage tank's hydrogen filling variable to this bus, and establishing hydrogen mass flow balance constraints among the models to characterize that at any given time, the total amount of hydrogen flowing into the bus equals the total amount flowing out. This invention solves the problem of insufficient accuracy in traditional models, achieving a balance between high accuracy of the equipment model and high solution efficiency for the optimization problem, providing a reliable modeling foundation for the optimal scheduling of hydrogen-containing integrated energy systems.

A Multimodal Data Retrieval Method Based on Semantic Association

This invention relates to a multimodal data retrieval method based on semantic association, belonging to the field of intelligent integrated circuits, and more specifically to the field of big data processing and artificial intelligence technology. The method includes: using an intelligent identification model to intelligently identify whether a scene-recorded video matched with an actual law enforcement scenario belongs to the first crime scene based on semantic association information, video association information, and image association information; if it does not belong to the first crime scene, retrieving the next scene-recorded video matching the actual law enforcement scenario for further intelligent identification. This invention addresses the technical problem that existing semantic association-based user retrieval methods cannot be applied to law enforcement scenarios. By employing a semantic association-based multimodal data retrieval mode in the legal documents and case databases of law enforcement departments, the retrieval continues until a relevant video belonging to the first crime scene of the actual law enforcement scenario is obtained, thereby solving the aforementioned technical problem.
