Power hardware-in-the-loop simulation testing of a flywheel energy storage system for shipboard applications

Energy storage is anticipated to play an important role on future surface combatants as specialized weapons and sensors systems are introduced, which may require high power and fast ramp rates over short periods of time. The energy magazine (EM) concept has been proposed as one approach for incorporating these types of systems into future, as well as existing, platforms. The EM is envisioned as a power converter with inherent energy storage capability, providing buffering between connected loads and the shipboard power generation system. This paper presents results from power hardware-in-the-loop (PHIL) simulation experiments in which an actual flywheel energy storage system (FESS) is tested as part of an emulated energy magazine, supplying a pulsating load.
