This paper presents an impedance-based stability analysis of metro traction power system considering regenerative braking application. Impedance model of vehicle-catenary traction system is first established, and impedance-based stability criterion is developed to analyze potential instability phenomenon caused by regenerative braking application. The analysis results reveal the relationship of stability and regenerative braking energy. Also, the relationship of grid strength and regenerative braking power is established. Simulation results are provided to validate the proposed impedance-based stability analysis method.
