Abstract: A new solution is proposed for the problems of economy of power consumption and stability of power supply system in different seasons in metro stations.Firstly, by fully considering the characteristics of different seasons and time periods, six different power supply modes are designed and switched according to the change of time periods in the actual power supply process.This flexible design of power supply modes can effectively cope with the power consumption demand of metro stations in different seasons and improve the economy of the power supply system.Secondly, in order to reduce the voltage fluctuation that may occur during the switching process of different modes, a hybrid energy storage capacity allocation mechanism is introduced.Byoptimizing the system parameters and adjusting the switching strategy of the power supply modes, the system can ensure the smoothness of the power during the switching process, so as to improve the stability of the power supply system and power quality.Finally, through comparison, the effectiveness and feasibility of the optimal scheduling scheme are concluded, providing new solution ideas and methods for the economy and reliability of the power supply system in metro stations.
