An energy storage system that converts irregular power to controlled power by a hydraulic power converter that utilizes the irregular power to pump hydraulic fluid, stores at least a part of the pumped hydraulic fluid in a pressurized accumulator cluster, and provides controlled power by a hydraulic motor operated by pressurized hydraulic fluid from the accumulator cluster, according to a specified power demand. The operation of the hydraulic power converter may be controlled electrically and mechanically, and the hydraulic power converter may be integrated in a vehicle, to maintain an optimal operation range of the engine, or in an energy production device, for generating controlled power from the irregular output of the device. |
