Architecture of Railway Self-Coordinated Energy System Based on Polymorphic Clean Energy
As the nation accelerates the transition of the transportation sector's energy structure,the application of clean energy within this field is gaining increasing attention.The railway self-sufficient energy system,as a crucial component of energy transformation in the railway industry,plays a significant role in achieving energy self-suffi-ciency and enhancing energy efficiency,which contributes to reducing overall railway energy consumption and ad-vancing carbon peak and carbon neutrality goals.This study systematically examines the primary requirements of railway self-sufficient energy systems from four dimensions:safety,efficiency,environmental sustainability,and economic feasibility.Based on the"source-grid-load"framework,the study explores the integration mechanisms of railways with clean energy,focusing on the distinct opportunities for electrified and non-electrified railways in real-izing clean energy transitions.This research conducts an in-depth analysis of the characteristics and energy flow pro-cesses involved in the fusion of railway and clean energy systems,offering a detailed examination of their integra-tion models and suitability,thereby laying a theoretical foundation for constructing a railway self-sufficient energy system.Building on this foundation,the study further identifies typical application scenarios for both electrified and non-electrified railways and develops physical architectures suited to the features of self-sufficient energy systems in railways.Additionally,an evaluation index system is proposed,emphasizing aspects of architectural rationality,model diversity,environmental friendliness,and significant economic benefits to systematically assess the system's performance in practical applications.This evaluation framework not only facilitates a comprehensive assessment of the effectiveness of railway self-sufficient energy systems but also provides scientific support for technical path-ways and policy implementation towards low-carbon development in the railway sector.This study presents new perspectives and developmental pathways for the low-carbon transition of future railway systems and the deep inte-gration of clean energy.
