  • Electricity storage control device
    Patent number: 10807495
    Abstract: According to one embodiment, an electricity storage control device includes a setting unit, and a control unit. The setting unit sets, for each time zone, a target state of charge (SOC) of electric energy to be stored in an electricity storage device in the time zone. The control unit controls at least charging or discharging of the electricity storage device based on the set target SOC for each time zone, a SOC detected from the electricity storage device, and a voltage of a supply destination of electric power from the electricity storage device.

  • Power management apparatus, power management method and power management program
    Patent number: 9764649
    Abstract: According to an embodiment, a power management apparatus 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.

  • Power management apparatus and power management system
    Patent number: 9707862
    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.
