内容介绍：

Railway decarbonization requires more than replacing diesel traction with electricity; it calls for a system-level integration of train operation, traction power infrastructure, renewable generation, and energy storage. This lecture will first review the role of electrification in reducing railway emissions and the technical challenges created by highly dynamic train loads, regenerative braking, voltage constraints, and timetable-dependent power flows. It will then present modelling approaches for multi-train traction power networks, showing how train trajectories, dwell times, substations, and network losses can be represented within a unified energy-flow framework. Particular attention will be given to the coupling between train driving strategies and traction power supply performance: speed-profile optimization can reduce traction demand, while timetable coordination and network-aware control can improve regenerative braking energy reuse and reduce substation energy consumption. The lecture will also discuss emerging decarbonization technologies, including reversible substations, hybrid energy storage, renewable traction power integration, digital twins, and data-driven optimization. It will be of interest to researchers and practitioners working on railway electrification, train control, power systems, and sustainable transport.
