RAILWAY POWER MANAGEMENT DEVICE, RAILWAY POWER MANAGEMENT METHOD, AND RAILWAY POWER MANAGEMENT PROGRAM

摘要

In order to effectively use power such as regenerative power in a station facility, a power management apparatus for managing a power storage device which stores the power and discharges the power to a distribution system is provided, so that the power storage device effectively discharges the power. A power management apparatus of an embodiment is provided with storage means, discharge plan creation means, discharge instruction means. The storage means stores a discharge amount of a power storage device to a distribution system, correspondingly to a prescribed parameter. The discharge plan creation means, when storable regenerative power is generated, creates a discharge plan to determine a discharge amount of the power storage device, from past data stored in the storage means, of regenerative power amount of a train and the discharge amount of the power storage device to the distribution system. The discharge instruction means outputs a discharge instruction to the power storage device.
