摘要： According to one embodiment, a device for evaluating an energy storage device includes first processing circuitry and second processing circuitry. The first processing circuitry detects a plurality of times at which an amount of charge of the energy storage device satisfies a threshold condition, based on measurement data on the energy storage device in operation, selects a plurality of time intervals, calculates a charge-discharge efficiency in each of the time intervals based on charge-discharge command values belonging to the time interval, and divides a set of the charge-discharge efficiencies into a plurality of clusters and generates characteristic information on the clusters based on at least one of the measurement data and the charge-discharge command values. The second processing circuitry generates output data for displaying: transition data indicating transition of the charge-discharge efficiency belonging to the cluster; and characteristic information on the cluster.

摘要： A power control apparatus has a peak cut prediction unit that predicts a period of time to impose a restriction on power supply from a power system to a consumer based on a predetermined condition, a threshold setting unit that sets a predetermined threshold such that a power supply amount from the power system to the consumer does not exceed the threshold in the period of time predicted by the peak cut prediction unit, and a charge/discharge control command unit that stops power supply from the power system to the consumer and causes a power storage device to be discharged by an amount of demand power exceeding the threshold when demand power of the consumer reaches the threshold in the period of time predicted by the peak cut prediction unit.

摘要： Asynchronous operation of an external power-supply device activated in blackout with an internal power-source device placed in a house or a plant is ensured. A commercial power-source system and an external power-supply device are connected to a power-source line provided in a house, etc., through a double-throw switch. The house, etc., is provided with an internal power-source device including multiple power supplies being connected to a load through the power-source line. When a power-source monitoring unit detects the blackout of the commercial power-source system, a controller stops the respective operations of the internal power supplies, and switches over the double-throw switch from the commercial power-source system to the external power-supply device. After the external power-supply device is connected to the power-source line, the control unit starts following operation in the order of the power source having a less output capacity fluctuation and connects those to the external power-supply device.
