Demonstrated Rapid Ballistic Synchronization From Rest of a Hydraulically-Driven Synchronous Generator
We present a small-scale pneumo-hydraulic energy storage system (ss-CAES) which can provide frequency support to a power grid, as fast instantaneous reserve.This system is designed to be maintained at rest until called, thus avoiding idling costs.It utilizes a hydraulic drive train which transmits very high torque directly to the shaft of a synchro
