Abstract
Storage is an extremely important area of research and has several applications, including potential of furthering the integration of renewable in the grid. An efficient and cost-effective electric storage is a transformative technology and benefits the environment and decreases the reliance on conventional energy sources. Flywheel energy storage systems, unlike chemical batteries of around 75% efficiency, have the potential of much higher cycle-life and round-trip efficiency (RTE), without recycling battery chemicals at life-end. Determination of RTE of a storage system requires multidiscipline system modeling and simulations. The modeling and simulation presented in this paper determines the RTE of the flywheel storage system. The losses in the converter, magnetic bearings, and the machine losses (copper and iron losses) are considered for calculation of RTE. The loss variance due to power and speed change during the charging and discharging cycles are incorporated in the model.
