摘要： A power management device managing electric power in a load facility group including plural load facilities includes: a detector that detects an instantaneous value of power consumption for each of the plural load facilities; a forecaster that forecasts an instantaneous value of power consumption for each of the plural load facilities; an operation unit that obtains a difference between the value detected by the detector and the value forecasted by the forecaster, for each of the plural load facilities; a controller that outputs a storage command or a discharge command based on whether the difference obtained by the operation unit is positive or negative; and a storage/discharge device that stores/discharges electricity based on the storage command or the discharge command output by the controller. The power management device can respond to instantaneous and steep power consumption amount change in a load facility to enable efficient use of power.

摘要： An energy storage and regeneration system that converts irregular, non-constant, and variable input power to regular, constant, and controlled output power using hydraulics whereby the irregular input power is used to pump hydraulic fluid into an accumulator array where it is stored pressurized. Energy is released in a controlled fashion using a hydraulic motor operated by the pressurized hydraulic fluid from the accumulator array, in accordance with the specified power demand. One or more power units may be deployed depending on the amount of energy required at the output. Each power unit includes a hydraulic motor and associated floating accumulator whose internal pressure is controlled to maintain a substantially constant pressure differential across its associated motor. The system can be integrated into various energy system sources including renewable energy such as wind, PV or thermal solar, wave, tidal, etc.
