Abstract: This paper focuses on riding through cases when a VRB system is partially failed. A comprehensive experimental study and a theoretical analysis have been performed on such a case. Several failure situations have been considered and two operation modes are put forward to respond to the failure including the use of lower rated power and times rated power. The results indicate that two modes of operation for dealing with the VRB partial failure create no significant effect on VRB energy storage system efficiency, and hence providing a way to improve the reliability of VRB energy storage systems under emergency conditions.

Key words: VRB energy storage system, partial degradation, lower rated power, times rated power
