Rail Transit"Network-Source-Storage-Vehicle"Collaborative Energy Supply Technology System
In order to minimize energy consumption in rail transit systems,the coordinated power supply technology of"network-source-storage-vehicle"integrates with renewable energy power generation systems along the line.This approach establishes a new coordinated power supply technology system that enables efficient energy utilization across time and space.This paper comprehensively analyzes the fundamental composition and characteristic types of physical,informational,and social architectures within the coordinated power supply system.Building upon this analysis,it introduces a temporal and spatial matching evaluation method for"load-source"based on the core concept of asset energization from a systemic comprehensive evaluation and operational perspective.Furthermore,it elaborates on important technological systems such as multi-source integration,protection reconstruction,and elastic evaluation.Emphasizing efficient energy-saving operations,it focuses on high-efficiency and high-resilience energy self-consistency technology through coordination among network,source,storage,and vehicle components.Additionally,leveraging artificial intelligence and information technology tools is proposed to construct multi-level energy management systems aimed at achieving effective coupling of diverse energy flows while ensuring safe,stable,and cost-effective operation of the system.The paper systematically summarizes key technologies related to the"network-source-storage-vehicle"coordinated energy supply system for rail transit including architectural characteristics;evaluation;optimization;safe operation;as well as coordinated operation of the system.It also outlines technical composition systems relevant to coordinated energy supply systems providing valuable references for engineering practices.
