由于能源价格上涨和环境问题，节能技术受到越来越多的关注。沿着其他运输方式，铁路正面临着越来越大的压力，以提供更智能和更有效的电源管理策略。本文提出了一种综合优化方法，地铁运营，以最小化全天变电站的能源消耗，通过计算最合适的列车运行轨迹（驱动速度剖面）和时刻表配置。提出了列车运行轨迹优化算法和时刻表优化算法。列车运行性能受到许多密切相关的不同系统的影响。结果表明，采用最优列车运行轨迹和时刻表，可以显著降低变电站能耗和负荷，从而提高系统性能和稳定性。这也具有降低新地铁变电站投资成本的效果。
Energy efficient techniques are receiving increasing attention because of rising energy prices and environmental concerns. Railways, along with other transport modes, are facing increasing pressure to provide more intelligent and efficient power management strategies.This paper presents an integrated optimization method for metro operation to minimize whole day substation energy consumption by calculating the most appropriate train trajectory (driving speed profile) and timetable configuration. A train trajectory optimization algorithm and timetable optimization algorithm are developed specifically for the study. The train operation performance is affected by a number of different systems that are closely interlinked. Therefore, an integrated optimization process is introduced to obtain the optimal results accurately and efficiently.The results show that, by using the optimal train trajectory and timetable, the substation energy consumption and load can be significantly reduced, thereby improving the system performance and stability. This also has the effect of reducing substation investment costs for new metros.
