Abstract
In one embodiment, a power management apparatus creates a switching plan for switching control of opening/closing of a first switch provided between an energy storage device and a distribution system side, and a second switch provided between the energy storage device and a feeder side, both of which are not closed simultaneously. Further, the power management apparatus determines a switching control content to the first switch and the second switch, according to the created switching plan, and outputs a determined instruction to the first switch and the second switch. In this configuration, the power management apparatus determines presence or absence of interchange of regenerative power between trains up to an optional unit time later, based on train information including an operation diagram, and when the interchange of the regenerative power between the trains is present, creates the switching plan to close the first switch for the unit time, and when the interchange of the regenerative power between the trains is not present, creates the switching plan to close the second switch for the unit time.
