Simulation of the interaction between flywheel energy storage and battery energy storage on the International Space Station

摘要

Replacement of one module of the battery charge discharge unit (BCDU) of the International Space Station (ISS) by a flywheel energy storage unit (FESU) is under consideration. Integration of these two dissimilar systems is likely to surface difficulties in areas of system stability and fault protection. Other issues that need to be addressed include flywheel charge and discharge profiles and their effect on the ISS power system as well as filter sizing for power quality purposes. This paper describes a SABER/sup TM/ based simulation to study these issues.
