PROBLEM TO BE SOLVED: To suppress reduction of acceleration performance of a train accompanying reduction of an electro line voltage by suppressing reduction of the electro line voltage when a schedule is disturbed.SOLUTION: A power supply and demand system includes a power storage device installed on the ground, a power converter connected between the power storage device and an electro line and configured to discharge electricity from the power storage device to the electro line and charging electricity from the electro line to the power storage device, and a charging/discharging control device for outputting a control signal to the power converter to control charging/discharging of the power converter. The charging/discharging control device obtains a prediction schedule predicting the future running state of each train, and obtains a train delayed in running on the basis of the prediction schedule, and controls the power converter so as to discharge electricity from the power storage device to the electro line at the acceleration timing of the delayed train. |
