Abstrakt

This paper presents a novel DC microgrid-enabled metro traction power system (MMTPS), where the renewable energy sources and regenerative braking power of metro trains are unifiedly managed by DC microgrid to reduce the energy consumption and obtain the economic benefits for metro traction power system (MTPS). The concept and system structure of MMTPS is first developed, where the metro energy router (MER) is presented to dynamically integrate the DC microgrid into MTPS. Furthermore, the four operation modes of MMTPS are defined and analyzed, including voltage control mode, power control mode, regenerative braking-supporting mode and islanded mode. In addition, the control strategies are developed to support the operation of MMTPS with the different operation modes. The simulation results show the stable performance of proposed control strategies, which thus validates the effectiveness of the MMTPS. The proposed MMTPS is able to reduce the energy consumption and improve the reliability of MTPS.
