Abstract

Resilience in the context of power systems involves several aspects of design, control, and monitoring. The uninterruptible power sources (UPS) are mostly adopted for several applications, to prevent data loss, to temporary power providing for mission-critical and safety-critical systems, like medical devices or strategical systems. The most adopted solution is still to use lead-acid batteries. The monitoring of the status of the battery pack in UPS, in which the pack is maintained charged for a long time, is of interest, to prevent catastrophic failures due to the unexpected battery fault. In this paper, the application of the SFRA online is proposed for the evaluation of the UPS performance, as a first step for the proposal of a resilience-oriented monitoring methodology. The testing system and some experimental results are presented and discussed.
