研究考虑列车混行的运行-调度一体化优化方法.通过对再生制动能量的利用，将列车的运行与调度联系起来，建立以能耗最优为目标的列车运行-调度一体化优化模型.考虑不同速度等级列车之间的追踪间隔和越行行为，确保在列车行车安全的情况下，在优化列车运行曲线的同时优化列车时刻表，实现线路上运行能耗的全局最优.采用粒子群算法对模型进行求解，获得不同速度列车的运行曲线及时刻表.仿真算例表明，该方法的节能效果明显，不仅可以在运行能耗方面节省9.6%，列车之间的再生能利用也可以达到13.2%，平均每辆车节能可以达到7.6%；采用改进后的再生制动能量利用方法，可以将能量利用在常规方法的基础上提升12.7%.
Abstract: The integrated optimization method of scheduling and control in express/slow rail transit was analyzed. The running control and scheduling of the train were related by using regenerative energy. An integrated model of scheduling and control was constructed by optimizing energy consumption. The different levels of speed tracking intervals between trains, the overtaking behavior and the safety of the trains were considered in order to optimize train operation curve and train schedules at the same time and get the global optimum value of operation energy consumption. The particle swarm optimization algorithm was used to solve the model in order to obtain the operation curve and timetable of the different levels of speed trains. Results show that the model not only can save energy by 9.6% in the aspects of running, but also can save energy by 13.2% in the aspects of regenerative braking energy by the comparison with the current situation. The average energy saving can reach 7.6% per car, and the improved method of regenerative braking energy can save energy 12.7% more than the original design.
