摘要

本研究提出一种考虑储能装置部署的高速列车节能运行图优化方法。结合出发时间、停留时间和安全前车等约束条件，开发了一种混合PSO-SA算法来求解该模型。在宝鸡-兰州段进行验证，结果表明，可再生能源的即时利用率为47.26%，随着储能的部署，可再生能源的即时利用率上升到62.79%。在保证求解质量的前提下，混合算法的计算时间比传统算法减少了74.59%。与遗传算法相比，PSO-SA算法的最优结果提高了4.76%。经济分析强调在关键供电区域优先部署储能，以获得最佳成本效益，为可持续铁路运营提供可操作的策略。本研究为节能高铁系统提供了理论和实践见解。

Energy-efficient operation diagram optimization for high-speed trains considering energy storage device deployment

This study proposes an energy-efficient operation diagram optimization method for high-speed trains considering the deployment of energy storage devices. A hybrid PSO-SA algorithm is developed to solve the model, incorporating constraints such as departure times, dwell durations, and safety headways. Validated on the Baoji-Lanzhou section, results demonstrate an immediate regenerative energy utilization rate of 47.26 %, rising to 62.79 % with energy storage deployment. The hybrid algorithm reduces computation time by 74.59 % compared to traditional SA algorithm while maintaining solution quality. Compared with the GA algorithm, the optimal result obtained by the PSO-SA algorithm improved by 4.76 %. Economic analysis highlights prioritizing storage deployment in key power supply zones for optimal cost-effectiveness, offering actionable strategies for sustainable railway operations. This research provides theoretical and practical insights into energy-efficient high-speed rail systems.
