Nowadays, energy conservation and emission reduction have become the top priority of metro systems. This paper concentrates on the application of regenerative braking technology in the energy-saving operation of metro systems. The research focus of this paper is maximizing the utilization of regenerative energy. We propose an energy-saving optimization method for train operation plans. Firstly, the train operation plan optimization model is constructed based on the adjustment of train operation interval and opposite departure interval. Secondly, we design a simulation algorithm that can effectively solve such a problem. Finally, the real-world line structure and speed profiles are used to verify the effectiveness of the optimization model and the algorithm. The results show that the optimization effects of this method are 0.8% and 2.2%, respectively, during peak and off-peak hours when the power grid is separated, and the optimization effects are 3% and 3.6%, respectively, during peak and off-peak hours when the power grid is connected. The method improves the utilization of regenerative energy and reduces the waste of resources significantly. Compared with taking the overlapping time to represent available regenerative energy, the energy calculation method proposed in this paper is more accurate.
