Abstract
With the rapid development of electrified railways, energy consumption continues to rise, making it imperative to optimize energy structures and promote green, low-carbon transitions. High-speed railways operate under heavy loads and at high speeds, while urban rail transit systems frequently start and stop, generating substantial regenerative braking energy that accounts for 10% to 40% of traction energy on heavy-load or long-gradient routes. Effectively recovering and utilizing this energy is a crucial strategy for alleviating the pressure of railway energy consumption. In alignment with the "dual-carbon" goals, this paper explores the feasibility of integrating new energy sources and energy storage systems into traction power supply systems, focusing on the recovery and utilization of regenerative braking energy in maglev trains during braking. To overcome the limitations of individual utilization methods such as energy dissipation-based, train scheduling-based, feedback-based, and energy storage-based approaches, a hybrid utilization scheme is proposed to enhance energy recovery efficiency. The findings offer valuable insights for reducing energy consumption in rail transit and advancing the development of green railways.
